As answered here

boolean verifyInstallerId(Context context) {
    // A list with valid installers package name
    List<String> validInstallers = new ArrayList<>(Arrays.asList("com.android.vending", "com.google.android.feedback"));

    // The package name of the app that has installed your app
    final String installer = context.getPackageManager().getInstallerPackageName(context.getPackageName());

    // true if your app has been downloaded from Play Store 
    return installer != null && validInstallers.contains(installer);
}

You can check either your app is installed from Play Store or not and accordingly show them the pop-up.
