How to integrate multiple apps into one using Android Studio

Question

I'm working on a project where I've to integrate two Android apps into a single app, using Android Studio IDE.

For example, I have App_A and App_B; these two Android apps are from two separate vendors. Now I've to integrate App_B inside App_A. Hence there would be a single AndroidManifest.xml file (of App_A) with MainActivity (launcher) and a single apk would be generated.

So far, I've imported App_B as a module inside App_A. Now, I can run each module separately. But I've to create a single apk file comprising of two modules.

I've searched in different Android forums in the Internet and so far I've not found any suitable solution.

First of all, I want to know whether it's possible to integrate two Android apps from two different vendors into a single Android app. If it's possible then please provide a solution to this issue. Also it would be a great help if you can send me your suggestions, ideas or any links regarding this issue.

Thanks & regards,

Answer 1

Yes you can do that:

1. Import the third party app's source code as a separate library module.

2. Modify the dependencies section of your Main module's build.gradle file to include the third party module as a dependency like this:

   compile project(':your_module_name_here')

Answer 2

You can launch other apps activities from your main app. It's the same as integrating facebook, you declare com.facebook.LoginActivity in your manifest. In Project_A manifest file declare activity from Project_B. FB eg:

 <activity
        android:hardwareAccelerated="false"
        android:name="com.facebook.LoginActivity"
        android:theme="@style/Vinted.NoActionBar"
        android:screenOrientation="portrait"/>

Also don't forget to include Project_B in gradle, FB eg:

compile('com.facebook.android:facebook-android-sdk:3.23.1')
