Why make Mobile App?

In this article I shall write about how to create and develop a successful app. A successful app means that app which proves good for monetisation. Which incurs heavy profits for developer. In the coming up series of article hopefully I shall write about the skills and techniques associated with for productio and development of a detailed app with its database management so that not only you gain assess to monetisation of your app but also you can build upon alternative career with it.

When you run and develop app in play store and finds it well equipped for monetisation then you can go for professional app development. It can make your career to reach towards ultra level heights so that you can rebuild it. There is no age limit and no educational barriers for this in order to understand and learn how apps works and how to create a good app from this.

How to Create a Successful App?

Mobile app can be that of android or for iOS and the process of development constitutes of idea, prototype, design, develop and launch of app in play store. These are the steps for development of app. When you have an idea of building some thing or that of building an app then firt thing comes to the mind is that whether you wants to make it up for wallpapers or for database or for gaming. It contains design and programming.

Mobile app development is not all about coding but the lements that is associated with it is the desing of the mobile apps as the concept or design is prime importance on design and it is the focus towards it and it is important to understand this in order to develop mobile app development. Draw how should app looks like and you can take inspiration from other apps or you can solely create the design of your app and think what should have been the prime focus and importance attached with it so that you do not have to be confused while entering into coding stages.

Then ask yourself how much code language do you know if you know it then it is good and if you have no knowledge still you can create mobile app as you do not have to worry about it at all.As per esitamtes and the amount of langauge use we have seen the presence of Python in data language setting is on the higher side as it is the ost easier form of code language and java is difficult but still it is popular and it is one of oldest language form to stay so we should also build some app with it.

What ever be you should be using java from time to time in the cases of mobile app development. Coding of mobile app development is one side but it is not all of the mobile app, as design and development and distribution are the vital part of mobile app development and coding is the back end process which you will do to connect all o these. Most of people think mobile app development is all about coding and coding but it is not that true.

App Development Options:

After development of apps the next is to publish apps those on play stores. There are two types of app one is that of native apps and their other is that of hybrid apps. Native apps can only run with specific platforms such as Apple-iOS or Android. Hybrid apps works in both. Native apps provide platforms for hybrid apps to work. In order to publish your app in Google Play Store or Apple iOS you have four options and four steps to go on.

First is the developer license, publishing procedure, guidelines for description and device availability. Here we will learn more towards Android developer options though in the process you can learn to develop hybrid app so that it can work on both playstore that of android and Apple-iOS. Developer license is 99$ a year and it is renewable in each year. You can upload as many apps as you could with this sum of money. It is important for you to understand that when you become an experience developer then you can release the app in Apple iOS system so that it will not hurt you financially.

For Google Play Store it is one time fee of 25$ and you do not have to pay fee again and you can upload as many apps as you can with this sum and it is one time membership fee for you and for this it is important for first time developer should concentrate on developing apps for android platform so that you will not be facing any sudden financial loss with it. Then comes the process of publishing process and this is known as uploading of app to play store or Apple store. Apple provides the review process for each and every apps and it is from three days to two to three weeks but in most cases within one week you will find the response of it.

The review process or the publishing process in Apple play store is very stringent and it can deny permission for publishing based on the siilarity of app, not so unique app and so on so it is important for develoepr to understand that when you develop an app the first point is to publish within android play store as there is no review process with it so you can publish app fter obtaining developer license. In the play store there is no review process as after uplaoding app your app is published within 24 hours and then it is open for monetisation as with due course of time you caan go for word of mouth or for advertisement to obtain the specific app populairty and with due course of timeit comes to the stage of moentisation.

Both Apple and Android play store have very rigid and strong guidelines for publishing of app into their store. Android has the detailed instructions in PDF formats. For android no backbone of dashboard of coding required as it is flexible but for iOS the backbone of coding required as it is not open source. Android goes on with material designing for its guidelines for designing and for iOS the designs aesthetics and function. Apple does not provide detailed designing guidelines so it means it provides wider specifications but do concentrate that its review process is very stringent and for this it is important to go with the specific designing principle Apple has.

In the case of design availability which is the device in which your app is going to run then Apple has two types of device Apple iPhone and iPad but in the case with android it has so far more than 24000 different devices and still counting and increasing. This means you have to code app considering the compatibility with so many devices but alternatively with Apple it is not so as you oly have to work with two devices for device availability of your android device. Making app for two devices and making app for almost 24000 devices in terms of screen sizes, resolutions is far more difficult and that show the presence of development of responsive designing for android which makes apps to work in faster and more convenient way.

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.
