it is to detect whether the current app is installed newly, or got upgraded from a lower version.
There are many use cases for this functionality.

Check if first install:

public static boolean isFirstTimeInstalled(Context context) {
    try {
        long firstInstallTime = context.getPackageManager().getPackageInfo(context.getPackageName(), 0).firstInstallTime;
        long lastUpdateTime = context.getPackageManager().getPackageInfo(context.getPackageName(), 0).lastUpdateTime;
        return firstInstallTime == lastUpdateTime;
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return true;
    }
}

Check if app is upgraded:

public static boolean isAppUpgraded(Context context) {
    try {
        long firstInstallTime = context.getPackageManager().getPackageInfo(context.getPackageName(), 0).firstInstallTime;
        long lastUpdateTime = context.getPackageManager().getPackageInfo(context.getPackageName(), 0).lastUpdateTime;
        return firstInstallTime != lastUpdateTime;
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return false;
    }
}

Thank you and good luck!
