Security tips for android application developers

This post was most recently updated on May 29th, 2019

Android is most popular mobile operating system. Most of original equipment manufacturers are using as their prime operating system. It is from Google and its new versions come with faster speeds. More and more user-friendly and security features add ons comes up with each and every android versions. Of late with the latest version update comes primarily most of deeper security features to make operating system more user friendly and secure.

Prime component of android is its applications. Beginning from its home screen to keyboard, each and everything attached with updates and customisations with another app using at the same sphere. This made android an unique and most preferable operating system where each and every app department changes in accordance with user choices.

There are huge cache of android application reservoirs inside Google Play Store where we can find each and every free alternatives as well as paid ones so that we can use it as per ours choices and customisations. Similarly, we can change each and every segment of skins such as home screen, key board and so on and for this we can download alternative app from Google Play Store.

So, the importance attached with security of apps for android becomes immense and for this it is important for application developers to adhere with the updated terms and conditions of Google Play Store from Google so that never at any point of time they would face banning of application.

On the other hand Google always provides checks and balances to the functioning of these apps and first these apps has to undergo inside sandboxing system and then with android they are functioning inside sandboxing environment so that if at all any point of time there is chance of apps getting intruded into malwares then chance of these malwares getting into mobiles is far less as all of these operate inside sandboxing environment.

Application developers must see these security measures and security application process interface from Google and include while developing any app to release inside Google Play Store. It not only makes app secure but also get good mark from Google and that makes yours app popular and it gets you lots of revenue as the result of it.

From time to time Google helps application developers with some interesting interfaces and that provides enormous amount of help for the application developers. They should include these code snippets while developing apps. It is important for them not omit these checks and balances. It not only makes the code development easier for application developers but also makes them helpful to make their app secure and that not only creates more buzz among users but also the tendency of loyalty for security of apps comes with it.

Before releasing final version of app it is important to check your app in similar android testing environment and then release it with beta version so that live and user feedback lets you understand what you left behind and what are the essential you want to add in order to make your app running again and again. If you find any bugs then you can take expert opinion of expert advice from Google to make it run smoother and smarter again and again.

Should I Build an App or a Website

This post was most recently updated on April 22nd, 2019

In the era of mobile computing emergence of apps are there. Since the beginning of the internet, we do see a predominance of website and series of development orientation comes up with each and every builds of a website. Semantically speaking of app or website there are no confusions and about it. Both are parallel and to provide intense and detailed information about concerned websites.

In the course of times and development of the internet, there are times where we can see there are a clearer and smarter differentiation and some advantages one upon the other. That is why at some point of time webmasters feel not sure about whether to build an app or a website.

The story of the internet does almost similar to the development and emergence and rise of a website. With due course of time, we do see a clear pattern of development of a website and the emerging world wide web due to development of faster internet does provide huge denominations of development agendas that need to attain with each and every simultaneous year.

The modern web which evolves from the time of internet which started in 1989. It uses hypertext links phenomenon mainly which is not a new concept. It has been there since 1965. Its potential has been known and well furnished with the presentation of a web in 1989 through proper information management.

After almost two decades later when we see the emergence of the web it is completely different and more energetic than it was earlier started. First, it was aimed to build a world wide web so that messages can be seen through hypertext links to make website rendering successful.

In the eras of Windows XP and prior to that we have seen how there are web browsers from Microsoft, Apple and others to have the complete war among themselves, and that continues for sometimes until and unless the browser war along themselves settled and the permanent development of different features wrong browsers begin to surface.

After the completion of web browser wars, we see the predominance of Internet Explorer, Edge, Safari, Chrome, Opera, Firefox and that loads to the development oriented towards building up a stronger and secure web browser.

With due course of time, there are unanimous acceptances of all browsers so that a new set up of standards for cross-browser compatibilities, developed through World Wide Web Consortium and make it possible to accept and that makes the official end of browser war among all web browsers.

After making the functional realities of creating the cross-browser compatibility a reality, the competitive browser competitions ends and hen begins the process of strengthening security and stability of web browsers. In the era of web bowser competitions, the gain Is for users as they find more and ore feature phenomenon and that makes the running web browser easy and faster.

At the same time beginning of 2000 and later years we find the emergence of smartphones and tablets and with due course of time Google’s Android has become one of the most revered and popular mobile operating systems we do find the presence of a large number of smartphones being built by homemade companies with cheaper prices and that makes smartphone availabilities all over all around easier for people to afford and that provides the best smartphone experience with manageable pricing.

It provides ample opportunities for development of apps which are precisely customizable options to use with smartphones and run with its ample justifications for more and more provisional development of a website and another alternative way to develop and propagate it.

Due to the emergence of touchscreen mobility and its extreme compatible with smartphones the development of apps is mostly possible. In 1971 for the first time, Samuel Hurst developed the preliminary version of touch screen and that provides one of ample way to maximize exposures with computing devices

It all started with compatible versions of games in terms of apps to be played with iPod in 2001. The simple games like brick and solitaire can be found in these devices, where we do see how a single website with various levels of optimizations could be found with single set up known as apps for mobile devices.

In the first demo of very first iPhone which provides the beginning of well calculated and managed iPhone devices which provides room for the development of apps to be run with mobile operating system environment with due care.

Apple begins the first application store known as Apple store for its mobile devices and with the monetization options more and more developers and webmasters move to the complete development of apps so that they can showcase these in Apple store as well as people can download these apps to use these ins stores easily as well as the development of monetisation options that lead to proper and manageable ways for development of apps worldwide.

Now, the future of application development is great with the advent of newer and constructive application writing languages such as that of Go languages more and more users seems to provide more and more features while calculating and use of simple forms of languages.

Nowadays with apps, one can book railway, airlines tickets and find the tickets, book hotels, cab and can do plenty of things such as payments and other facilities that are readily available.

With the emergence of apps mostly we can find more and more individualized presentations of a website where customers can customize their user experience to find out more and more stupendous deals and work out their billings and other e-commerce purchases.

Even bigger electronic commerce houses such as Amazon, Flipkart and so are encouraging users to download an app and then register it with their username and passwords and then use it so as to find customizable experiences and suggestions for their purchases.

From all of these descriptions, one can conclude that there are so much of similarities between websites and apps but there are strengths of both in certain situations.

With the website, there are various customizable and popular prototyping available to develop one of biggest databases such as that of Joomla, WordPress, so that you can develop your website instantly without anything that of delay.

Due to constant set up of dedicated followers of each of prototyping, one can find the development standards of these websites in the terms of the latest version to make it perform and provide one of most ultra-modern interfaces with each and every presence of website management.

Due o presence of responsive website designing it becomes easily compatible with most of we designing parameters and performs nicely with different web browsers without difficulties.

If your host is providing enough resources then building up a robots applications with the help of your resources from hosting side is possible and that can manage both website and apps without any difficulties.

Due to an addition of too many of add-ons we do find more and easier website performance management and making it more secure through the presence of content delivery network and hardware firewall etc. to make the website run without any difficulties.

Due to constant updates of these prototypes from the dedicated source of developers we do and more and more performance boosts and security embedded within these so as to present users with more and more dynamic and performance boost channels so as to run the website with an extremely secure environment.

Now, we do see the strengths of these websites are more and easier as we do see already some of the compatible tools to make it work automatically and boost the running of a website in clear-cut and advantageous manner.
Thre are many strengths of apps also.

Most of the apps are actively developed through software development kit which is provided by major internet providers such as Google, Apple, and the users have vast resources to learn it from and then utilize those resource to its perfection not find out the most easier option.

Most of these software development kits have the option for auto-correction of codings as well as most of the parts are well augmented through the presentation of a graphical user interface to develop an app without any difficulties.

Most of these gaming apps are now possible and with it most of the highly advantageous gaming performances with mobile devices are possible and that makes one of the most outstanding gaming markets within application measurements.

There are some apps which perform betters in apps and bad on a website and one is the vibrant example of this is Gmail which is smarter with apps and comparatively slower on a website.

With due course of time and with a proper and dedicated form of development we do find there are apps which are overpowering website versions.

The personalised service which we do find with apps comparatively variance with website to website while we do see with some electronic commerce website the presentation of apps and its customised content does provide one of most augmented presentations of straightforward rendering and managing of it but with some websites such as needs we do find that it is website that runs good and not the apps.

One of the most preferred functionalities of an app is the presence of offline use of it and that makes running of app extremely useful and this way it does provide one of the preferable solutions for better visibility action with the comparison to that of website version of a website.

In the end while building website one is certain what will be the cost of it in term of purchasing of domain and hosting, in the other hand first you have to decide which one you should try it out whether the web app that runs in web browser or the mobile app that can be included in mobile application environment or market.

How much application development cost as compared with a that of a building of websites and what are the profits and enormous development of website management should provide an intuitive interface to it?

In addition to, this when you want to develop a website then do search for why do you need it and what are the preconditional requirements for this and what are pros and cons of it and while doing so do always remember to manage these aspects to find out more and more economy and development-oriented purposes.

In the end, choose the right database modules or CMS such as that of WordPress or Joomla and which you need to use it for perfection and all of these should provide weather to build a website or build an app and then whether to build a web app or an android app for your betterment of web standards.

How to create your own Android Virtual Device in order to test your app created with Android Studio?

This post was most recently updated on April 18th, 2019

Android Virtual Device (AVD) is meant for Android Studio, to test out the apps into a new phone so as to realize complete android virtual environment. In the upcoming series of tutorials, we will be learning about coding and other aspects. Prior to learning of Android Studio coding, t is important to learn all of these elements so that in the future when all of these are going to be implemented inside Android Studio there would be nothing difficult for you to attach and execute android apps.

There will be no confusions for you when you run apps and its related coding. In this tutorial, we will be learning about how to create our own AVD. In order to create AVD, we do need Android Studio (AS). First, click on the icon namely ‘AVD Manager’ which manages all of ours Android virtual devices at a single location.

After clicking on another window ‘Android Virtual Device Manager’ window will open. Now, in this Device manager earlier I had created two android virtual devices. One is ‘myAndroid’ which I have created from ‘Nexus 5’.

The original device manager is Nexus 5 and in order to keep the default settings intact, I have created another device from it so that even if when we simulate app on another device say here ‘myAndroid’ then, of course, the default settings of Nexus 5 will remain intact.

Now we are going to create the copy of the existing android virtual devices. Instead of editing the original one we will like to develop and create the copy of the device so that the original settings of the device remain as usual. From left side down of ‘Android Virtual Device Manager’ click on ‘Create Virtual Device’. The next window should pop up as ‘Select Hardware’ and then choose the device definition.

Here you will be given the choice of devices. Here we will choose ‘Nexus 5’. There is no compulsory to choose this device. You could choose any of these devices. Then go to the extreme right-hand side and below were written as ‘clone device’ and click on to it.

This simulator will clone the device of ‘Nexus 5’ and thus the original device configuration of ‘Nexus 5’ seems intact. Now ‘configure hardware profile’ window will open.

Here we will like to modify the RAM settings. In the original Nexus 5 device, the RAM setting is 1536 MB and we would like to reduce it so that simulator will work perfectly without taking too much load on system RAM.

In ‘Memory’ segment of ‘Configure Hardware Profile’ change the RAM into 1000 so that we could run the Nexus 5 modified device within 1000 RAM.

Then click ‘Finish’ and now inside ‘Select Hardware’ profile we have the new device named ‘Nexus 5 (Edited)1’ and then from the right-hand side and below of it click on ‘Next’.

Now, you will be reaching to another windows namely ‘System Image’ and here you will go to select Android Operating system images. If you have AMD processor then it is better to select or download ‘armeabi-v7a’ of Android 7 or Nougat. It should be there on the ‘Select a system image’ and inside ‘Other images’.

If your computer has Intel processor then you could choose from the list of recommended android system image from ‘Recommended tab’, Then click on ‘Next’ to reach to next window namely ‘verify configuration’. In the ‘Verify Configuration’ in the ‘AVD Name’ change the ‘Nexus 5(Edited)1 API 24’ to any of the names such as ‘MyEmulator’.

Verify Configuration

Here, we can find information related with which device is edited and which android system image and in this case we have installed ‘Android 7.0 armeabi-v7a’ and then the startup orientation of android device should be portrait or landscape, here we should select ‘portrait’ and make emulated performance of graphics to be set on ‘Automatic’ and it is your choice to enable or disable ‘Device frame’.

Device frame is the hardware side of viewing angle. You can expand ‘show advanced settings’ to go for advanced configuration but in most of the cases, this is not necessary. Then click ‘Finish ‘to return back to ‘Your Virtual Devices’.

Now, we reach the main windows of listings of virtual devices. Here, you will find our new android device such as ‘myEmulator’ and here you will see we have ‘Android 7.0’ arm central processing unit with 650MB RAM as we have distributed, 1000MB RAM as we would expect the system had taken 350 RAM so for the sake of other performs we have now 650 MB RAM.

In this way, we have created successfully our new android device namely ‘MyEmulator’. We can launch this AVD in emulator through the arrow button at the end of the name of the emulator. Click it and wait for sometime to the emulator to work.

Launching of emulator takes time in accordance with the speed of your computer and hardware configuration of the computer. Within some time one Android device will come up in a separate Window.

We have created a new AVD and launching of this AVD do take some time for the first run and subsequently, it does not take that much time to run from the second run onwards. While opening up android simulator two or more processes does run in the background and that can be seen from the footer of Android Studio.

After AVD runs and then gradle device runs and then the background process is waiting for the target device to come online which means the apps which we have just built within Android Studio will slowly be converted into apk files and then run within these console or android simulator.

Android files are apk files which are similar to that of dot exe files of windows computers. Sometimes running of preview do take longer time due to presence of infinite loops inside app and for this it is important to refresh the layout so that running and launching of app should come out within seconds inside of android app and it is important to run the android simulator once again without closing the window of android simulator in order to launch the entire android simulator and its functioning.

In the second series of the launching of simulator the installation of APK which is the form of the app which we have constructed, should take some time and after that you could see your app is running inside the simulator. Which means this will be the prototype of our app with android 7 which should be compatible with all the other android versions up to android 4.01.

In this simulator, we have completely new android 7 which work in the normal way, and most of the normal android works can be done and with its stacked android web browser even one can browse the internet and do other forms and this means it is a complete Android system.

In this way we can run ours android app and see how it is performing and that means in a completely wonderful way we can see and find, how ours apps are performing in an better or inferior way so that ultimately, we do not have to go to physical android device and then test side by side how ours app is running and instead we do not have to search for android 4, 5,6,7 devices as we could do this all here with this simulator and in the future we would be reading about how to create log files, and then see how the functioning of app is there with complete and clarity in finding out how the app is performing.

How to Increase Jio 4g Speed

This post was most recently updated on July 9th, 2019

Jio launched its 4G volte service for faster internet. It came with revolution and that evolution reduced prices of competitors. Jio increases its user base to large numbers and became number one in terms of subscribers. of late we do find the slowness of Jio 4g especially during morning time.

This article is exactly dealing with this. I Have also found that speed of internet and the broken streaming of videos mostly in day time and I wish to find out its solutions. First look out whether Jio tower is nearer to yours locality or not and then if it is nearer and still there is slow connectivity this means that there are more that stipulated subscriber in your locality than it is aimed for.

Now it is time to install some of Jio apps such that connectivity will become faster. Fast install Jio and then Jio call app and if you wish to make Jio call yours default sms provider then you can do it or not do it it is as per yours wishes. In order to increase JIo 4G speed first download cloudflare VPN from Google play store.

With android use of vpn comes up with installation of VPN software and cloudflare VPN is one of the faster and secure virtual private network and it works for desktop as well as that for android devices too. It speeds up DNS queries of website and android faster.

Most of website and application connects to internet through DNS propagation and with it the connecting this with websites becomes faster as cloudflare is a content delivery network and most of website runs g of these websites becomes faster as it is circulated through world wider content delivery networks servers of cloudflare.

It has tunnel type and choose full tunnel for faster loading of website and then choose from encryption mode choose TLS. What it makes is that it speeds up internet connection and searching for DNS becomes faster with it, and with it comes loading of website or connected apps with faster internet connectivity.

With Jo 4G and with cloudflare VPn internet connections of finding out DNS queries becomes faster with it. If you are using jio 4g for tethering hotspot of sharing internet connectivity with computer then inside computer go to control panel and then to network and sharing center and then go to change adapter settings. Then go to Wireless network connection, then double click that and then go to properties and then choose IP4 or IP6 and then put the following DNS addresses into it.

IP version 4
1.1.1.1
1.0.0.1
IP version 6
2606:4700:4700::1111
2606:4700:4700::1001

Then save it and now you will find the faster and secure internet with more prone to protect privacy of individuals. In this way, even on slower Jio 4G connectivity you will find that by using cloudflare vpn app with android or Apple and then with Windows computer you will find the faster loading of websites and faster internet.
