I currently have an Activity that when it gets displayed a
Notification will also get displayed in the Notification bar.
This is so that when the User presses home and the Activity gets
pushed to the background they can get back to the Activity via the
Notification.
The problem arises when a User presses the back button, my Activity
gets destroyed but the Notification remains as I want the user to be
able to press back but still be able to get to the Activity via the
Notification. But when a USER tries this I get Null Pointers as its
trying to start a new activity rather than bringing back the old one.
So essentially I want the Back button to act the exact same as the
Home button and here is how I have tried so far:
---
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (Integer.parseInt(android.os.Build.VERSION.SDK)
< 5
&& keyCode == KeyEvent.KEYCODE_BACK
&& event.getRepeatCount() == 0) {
Log.d("CDA", "onKeyDown Called");
onBackPressed();
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed() {
Log.d("CDA", "onBackPressed Called");
Intent setIntent = new Intent(Intent.ACTION_MAIN);
setIntent.addCategory(Intent.CATEGORY_HOME);
setIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(setIntent);
return;
}
---
However the above code still seems to allow my Activity to be
destroyed, How can I stop my Activity from being destroyed when the
back button is pressed?
