android - How to stop an app after some time?

Question

Hei! In my android app I have a button that starts the app Barcode Scanner. I want to stop this app after 2 minutes, for example. How can I do this?

This is my code :

qrgame = (Button) findViewById(R.id.qrgame);
qrgame.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(
                        "com.google.zxing.client.android.SCAN");
                intent.setPackage("com.google.zxing.client.android");
                intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
                startActivityForResult(intent, 0);
            }
        });

Answer 1

you can finish your activity as you can start your activity using

startActivityForResult(intent, 0);

you need to pass the same requestcode to this method

finishActivity(requestCode);

for delay time you can you Thread, Timer etc.

Or you can close your opened activity just implement Timer, thread which will hold you 2 min or as per your requirement then call

finish();
