Add method to check which App Store the Android app is installed from, or if it’s sideloaded.

Spartan Sprint San Jose 2019. I completed my Spartan trifecta on March 17, 2019.

Java Code:

/**
 * Get the name of App Store the App is installed from.
 */
public static String getAppStore(Context context) {
    String pName = BuildConfig.APPLICATION_ID;

    PackageManager packageManager = context.getPackageManager();
    String installPM = packageManager.getInstallerPackageName(pName);
    if ("com.android.vending".equals(installPM)) {
        // Installed from the Google Play
        return "Google Play";
    } else if ("com.amazon.venezia".equals(installPM)) {
        // Installed from the Amazon Appstore
        return "Amazon Appstore";
    }
    return "unknown";
}

Debug in log

Log.d("myApp", "getAppStore: "+ Utils.getAppStore(this));

Kotlin code:

/**
 * Get the name of App Store the App is installed from.
 */
fun getAppStore(context: Context): String {
    val pName = BuildConfig.APPLICATION_ID

    val packageManager = context.packageManager
    val installPM = packageManager.getInstallerPackageName(pName)
    if ("com.android.vending" == installPM) {
        // Installed from the Google Play
        return "Google Play"
    } else if ("com.amazon.venezia" == installPM) {
        // Installed from the Amazon Appstore
        return "Amazon Appstore"
    }
    return "unknown"
}

Thanks for reading :)
