how to show a dialog after 1 or 2 min after opning app for first time

Question

I want to show a custom XML dialog dialogue that will appear after a specific time in the first run, let's say after a min

how can I do it

but I'm confused about what should I do in a situation like below

• if the user open the app for the first time and just spent 30 sec and just pause the app(screen lock or in onPause) or just close the app completely

Just as a note - I have already implemented a one time show dialog(directly in main activity without any layout file ) when the app runs for the first time already

Code

To view the already implemented dialog(shows up on the first run) please go to the // Caution dialog (showDialog method)

Answer 1

but I'm confused about what should I do in a situation like below

if the user open the app for the first time and just spent 30 sec and just pause the app(screen lock or in onPause) or just close the app completely

This is impossible to do if your app is closed.My suggestion would be to create a service on another process that does this dialog such that even if the app process is closed,the service process will still be running unless it is stopped explicitly. Defining a Process of a Service

The android:process field defines the name of the process where the service is to run. Normally, all components of an application run in the default process created for the application. However, a component can override the default with its own process attribute, allowing you to spread your application across multiple processes.

If the name assigned to this attribute begins with a colon (':'), the service will run in its own separate process.

<service   android:name="com.example.appName"   android:process=":externalProcess" />

This is of course in the manifest file . You might also need to show a system dialog thus you will need a system Alert Window permission i your manifest and request for the permision on runtime.

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

Then on runtime request like this:

  public static void openOverlaySettings(Activity activity) {
        final Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + activity.getPackageName()));
        try {
            activity.startActivityForResult(intent, 6);
        } catch (ActivityNotFoundException e) {
            Log.e("Drawers permission :", e.getMessage());
        }
    }

To check if granted use :

if(!Settings.canDrawOverlays(context)) {
            openOverlaySettings(context);
            ok=false;
        }

Then in your service you should create the dialog like below

View aldv= LayoutInflater.from(act).inflate(R.layout.your_layout,null);
        ald=new AlertDialog.Builder(act,R.style.AppTheme)
                .setView(aldv)
                .setCancelable(true)
                .create();
                ald.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
