Is any alternate of Intent.FLAG_ACTIVITY_REORDER_TO_FRONT

Question

I am creating Two activities as below now when click on button from MainActivity it shows SecondActivity and on click button from SecondActivity shows MainActivity normally but now on click soft back button Device show ANR.

MainActivity buttonClick -> SecondActivity buttonClick -> Soft back click , results ANR.

Is there any workaround?

This issue with Android 4.4.4. I know about this https://code.google.com/p/android/issues/detail?id=63570#c2 issue.

Thanks for any help.

        TextView tv;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            tv = (TextView) findViewById(R.id.textView1);
            tv.setText("Main Activity");

        {
            Intent intent = new Intent(this, SecondActivity.class);
            startActivity(intent);
        }

Post the logcat please – Triturable

thanks for help but its not work..(finish is just for show log) – Albina

@Triturable : nothing in logcat just show ANR Launcher isn't responding. – Albina

is there anything u r doing apart from posted above in activity? – Resplendent

try to use in your manifest file, within activity tag android:parentActivityName="your first Activity" – Thoracoplasty

What should happen when user presses on back button? Your code is only that much? – Triturable

@DIVA no, i just test this code on NEXUS 7 android 4.4.4 – Albina

@Triturable when user presses on back button just close Activities one by one.. – Albina

I've got the same behavior with Nexus 7 android version 5.0.2 and Nexus 5 android version 5.0.1. – Geothermal

Answer 1

use intent.setFlags (Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_CLEAR_TOP); the application will not crash.
