Clear upto a specific activity from the stack history
Suppose I have activities named A, B, C, D. Now, consider A has been launched as the root activity and B has been launched from A and C has been launched from B and D has been launched from C.
Now I have a button named "Success" in the activity D. If suppose, I press the button "Success" in the activity D, then the activity C should be removed from the history stack and go to activity B, but on Pressing back key from the activity D should display activity C instead of B and Clear D from stack. Please can anyone help me to resolve this problem?

If you organised this in activities, and are all part of a, let's say, step by step which my vary depending on the previous, I strongly believe in the power ofstartActivityForResultandonActivityResult

Add this Code in your Activity_D for Button click
btnSuccess.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(Activity_D.this, Activity_B.class));
finishAffinity();
}
});
Also add this in your Activity_D to Handle Back Button Pressed.
@Override
public void onBackPressed() {
finish();
super.onBackPressed();
}
From Activity_C to Activity_D
startActivity(new Intent(Activity_C.this, Activity_D.class));
Don't call finish() here.

Thanks. But as per your code, the stack is not clearing. and when I click back button from B it will go to activity D. So I hope this will not work for me.

When you click on Success button, you can use the following line of code to open your B activity:
Intent d_intent = new Intent(D.this, B.class);
d_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
d_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(d_intent);
finish();
Here Activity B will be started from the back stack rather than a new instance because of Intent.FLAG_ACTIVITY_CLEAR_TOP and Intent.FLAG_ACTIVITY_NEW_TASK clears the stack and makes it the top one. So when we press the back button the whole application will be terminated. And on Back press you need to simply call
finish();
Hope it will help you out.

In that case, you can try this without Intent.FLAG_ACTIVITY_NEW_TASK flag

When you click on Success button, you can use the following line of code to open your B activity:
Intent d_intent = new Intent(D.this, B.class);
d_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
d_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(d_intent);
finish();
Here Activity B will be started from the back stack rather than a new instance because of Intent.FLAG_ACTIVITY_CLEAR_TOP and Intent.FLAG_ACTIVITY_NEW_TASK clears the stack and makes it the top one. So when we press the back button the whole application will be terminated. And on Back press you need to simply call
finish();
Hope it will help you out.
