GCM How do I detect if app is open and if so pop up an alert box, instead of normal notification flow?

Question

I have an app where I want to build 2 different flow\'s in:

• 1.a App is open on any activity

• 1.b App show\'s an alertbox where user can choose to go to

Answer 1

A solution I just found does require a GET_TASK permission:

ActivityManager activityManager = (ActivityManager) getApplicationContext().getSystemService(Context.ACTIVITY_SERVICE);
List services = activityManager
        .getRunningTasks(Integer.MAX_VALUE);
boolean isActivityFound = false;

if (services.get(0).topActivity.getPackageName().toString()
        .equalsIgnoreCase(getApplicationContext().getPackageName().toString())) {
    isActivityFound = true;
}

Log.d("GCM", "Activity open: "+isActivityFound);

UPDATE

In order to launch an alertbox (which isn't possible here) I created a custom alert box and let it use the AlertBox as theme. This is the activity in AndroidManifest.xml:

And the custom activity:

public class NotificationAlertActivity extends Activity implements
        Observer, OnClickListener {

    private String pendingObjectId;
    private ModelFlag modelFlag;
    private Database db;
    private ArrayList discussions;
    private ArrayList tips;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notification_alert);

        findViewById(R.id.button_yes).setOnClickListener(this);
        findViewById(R.id.button_no).setOnClickListener(this);

    }

I updated the onHandleIntent with this bit:

if (isActivityFound) {
    Intent dialogIntent = new Intent(getBaseContext(),
            NotificationAlertActivity.class);
    dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    getApplication().startActivity(dialogIntent);
}
