Question

I have an Activity called MyProgressDialog which contains a ProgressDialog. This ScreenProgressDialog activity is called in the Main activity by intents:

       if(msg.what == SET_PROGRESS){

            intent.putExtra("action", "set");
            ...

            intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);

            startActivity(intent);
        }
        else if(msg.what == SHOW_PROGRESS){             


            intent.putExtra("action", "show");
            ...

            intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);

            startActivity(intent);              
        }
        else if(msg.what == HIDE_PROGRESS){

            intent.putExtra("action", "hide");

            intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

            startActivity(intent);

        }

Here is the MyProgressDialog activity:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Log.e("screenPD", "spd created");

    extras = getIntent().getExtras();



    pd = new ProgressDialog(this);

    ...setting the pd...        

    pd.show();  

    Log.e("screenPD", "spd shown");
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    setIntent(intent);

    int newTitle = intent.getExtras().getInt("title");

    if (intent.getExtras().getString("action").equals("set")){
        pd.set methods...
        pd.show();

        Log.e("DialogSET", "DialogSET "+intent.getExtras().getInt("progress"));
    }
    else if (intent.getExtras().getString("action").equals("show")){
        pd.set methods...
        pd.show();

        Log.e("DialogSHOW", "DialogSHOW "+progress);

    }
    else if (intent.getExtras().getString("action").equals("hide")){
        pd.dismiss();
        this.finish();
        Log.e("DialogHIDE", "DialogHIDE");
        return;
    }
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.e("screenPD", "destroyed");     
}

And here is the LogCat:

DialogHIDE(2615): DialogHIDE
screenPD(2615): spd created
screenPD(2615): spd shown
screenPD(2615): destroyed

So the 3rd intent starts, calls the finish(); return; and the Onreate method is started which displays a new ProgressDialog. The onDestroy is called, but the ProgressDialog doesn’t hide from the screen. After the finish() method the activity shold be closed. Where is the problem? Thank you!

Answer 1

There is no error. the method invoking finish() will run out to completion and after its completion the controll returns to Android
