How to know an application is installed from google play or side-load?

Question

I need to detect my application is installed from google play or other market, how could I get this information?

Answer 1

The PackageManager class supplies the getInstallerPackageName method that will tell you the package name of whatever installed the package you specify. Side-loaded apps will not contain a value.

EDIT: Note @mttmllns' answer below regarding the Amazon app store.

Answer 2

And FYI apparently the latest version of the Amazon store finally sets PackageManager.getInstallerPackageName() to "com.amazon.venezia" as well to contrast with Google Play's "com.android.vending".

Answer 3

I use this code to check, if a build was downloaded from a store or sideloaded:

public static boolean isStoreVersion(Context context) {
    boolean result = false;

    try {
        String installer = context.getPackageManager()
                                    .getInstallerPackageName(context.getPackageName());
        result = !TextUtils.isEmpty(installer);
    } catch (Throwable e) {          
    }

    return result;
}

Kotlin:

  fun isStoreVersion(context: Context) =
    try {
      context.packageManager
        .getInstallerPackageName(context.packageName)
        .isNotEmpty()
    } catch (e: Throwable) {
      false
    }

Answer 4

If you are looking at identifying & restricting the side-loaded app. Google has come up with the solution to identify the issue.

You can follow as below

Project's build.gradle:

buildscript {
 dependencies {
  classpath 'com.android.tools.build:bundletool:0.9.0'
 }
}

App module's build.gradle:

implementation 'com.google.android.play:core:1.6.1'

Class that extends Application:

public void onCreate() {
if (MissingSplitsManagerFactory.create(this).disableAppIfMissingRequiredSplits()) {
    // Skip app initialization.
    return;
}
super.onCreate();
.....

}

With this integration, google will automatically identifies if there are any missing split apks and shows a popup saying "Installation failed" and it also redirects to Play store download screen where user can properly install the app via the Google Play store.

Hope this helps.
