Not able to close app from Dialog in android

Question

I want to add one functionality in app. I want to close the app while I click on exit button but my button is on Dialog so when I try to use finish() is does not do the same. I just want to close the app.Please help.

// code for the same

    if (v.getId() == R.id.imgLogout) {

        AlertDialog.Builder alertDialog = new AlertDialog.Builder(getContext());
        alertDialog.setMessage("Are you sure you want to exit?");
        alertDialog.setPositiveButton("YES", new OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // session.logoutUser();
                finish();


            }
        });

Must sure before you calling _finish()_ you'r dismissing dialog by _dismiss()_ — Piyush, Sep 04 '17 at 07:08

First Close All Paused Activity. Than You Can Close App. You Remember this activity is last.

if (v.getId() == R.id.imgLogout) {

    AlertDialog.Builder alertDialog = new AlertDialog.Builder(getContext());
    alertDialog.setMessage("Are you sure you want to exit?");
    alertDialog.setPositiveButton("YES", new OnClickListener() {

     public void onClick(DialogInterface dialog, int which) {                
           finish();
          // context.finish();  if use in fragment
       }
   });

Firstly in your dialog class pass the context of the caller activities say MainActivit.class context

Now first close the dialog

//so as to avoid the window leaks as on destroying the activity it's context would also get vanished.

 dialog.dismiss();

and then

((Activity) context).finish();

A very simple way to close app is:

Intent intent = new Intent(Intent.ACTION_MAIN);
                    intent.addCategory(Intent.CATEGORY_HOME);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(intent);
                    finish();

So in your case try this:

 if (v.getId() == R.id.imgLogout) {

    AlertDialog.Builder alertDialog = new AlertDialog.Builder(getContext());
    alertDialog.setMessage("Are you sure you want to exit?");
    alertDialog.setPositiveButton("YES", new OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            // session.logoutUser();
            Intent intent = new Intent(Intent.ACTION_MAIN);
                    intent.addCategory(Intent.CATEGORY_HOME);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(intent);
                    finish();


        }
    });
