Hi Mike,
I would suggest a better approach for this.
------------------------------------
Firstly I will put your problem in my worlds what I understand:
You have 3 Activities ActivityA, ActivityB, ActivityC.
ActivityA is starting activity.
Activities launch sequence is:-
ActivityA -->(On some user action) --> ActivityB --> (After some time,
say 5seconds) --> ActivityC
And closing sequence:-
ActivityC -->(On Back button press) --> ActivityA. (Skipping
ActivityB from stack) -->(Pressing back key from ActivityA will exit
the application)
--------------------------------------
Solution:-
-----------------
Step1- In ActivityA on some user action start ActivityB
public void someUserAction() {
Intent intB = new Intent(ActivityA.this, ActivityB.class)
startActivity (intB); // This will start ActivityB keeping
ActivityA below in the stack.
// Note: don't call finish() here, in this Activity.
}
----------------
Step2- In ActivityB, on some timer timeout, start ActivityC with
startActivityForResult
public void onSomeTimerTimeout () {
Intent i = new Intent(ActivityB.this, ActivityC.class);
startActivityForResult(i, 1001); // 1001 is just some request
code.
You will need this in onActivityResult() (step4)
// This will start ActivityC keeping ActivityB in
stack below ActivityC for the background blur look-n- feel as you
need.
}
-----------------
Step 3- In ActivityC handle back key press:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
setResult(RESULT_CANCELED);
// This will set the Result as RESULT_CANCELED and finish
this AvtivityC. Going back to ActivityB.
finish();
return true;
}
else {
return false;
}
}
------------------
Step4- Now back in ActivityB, override onActivityResult()
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (resultCode == RESULT_CANCELED) {
finish();
// This will check if the result is RESULT_CANCELED (set in
ActivityC), and finish this ActivityB without even showing up the
screen for ActivityB. So user will feel like going back to ActivityA
directly from ActivityC.
}
-----------------
Step5- Note: Keep all window manager flags (Blur, transparent)
unchanged. As per your requirement.
------------------------------
Try this out, and revert back in case of any queries.
