how to return back to the previous activity

Question

i have three activities A, B and C. when i press a button in activity A it starts activity B and when i press a button in activity B it starts activity C. up to here there is no problem.

but when i press the back button on activity C it should returns me back to B. but what happens could be described as follows:

1st time B starts C, then C goes back to B
2nd time B starts C, then C goes back to B
3rd time B starts C, then C goes back to B
4th time B starts C, then C goes back to B

and so on,

now, when I press the back button on B it should navigates me back to A, but what happens is, when i press the back button on B it returns me to B over and over again to B as much as B started C. if the activity B started C 5 times, then when press the back button on B it returns me 5 times to the same activity B and in the 6th time it returns me to A

please let me know why that is happeneing and how to solve it

code

//in activity C
@Override
public void onBackPressed() {
    super.onBackPressed();

    new Intent(SchadenListeActivity.this, 
VersMoreDetailsModActivity.class);
    finish();
}

//in activity B
@Override
public void onBackPressed() {
    super.onBackPressed();

    new Intent(VersMoreDetailsModActivity.this,   
 VersicherungsListeActivity.class);
    finish();
}

Answer 1

You are creating new instances of Activity in onBackPressed.Simply,remove the intent statements from your activities.

//in activity C

@Override
public void onBackPressed() 
 {
 super.onBackPressed();
 finish();
}

//in activity B

@Override
public void onBackPressed() 
 {
 super.onBackPressed();
 finish();
}

Answer 2

Include parent activities in your manifest with the attribute android:parentActivityName="com.example.myfirstapp

Answer 3

When you go from A->B->C dont finish any of the activity. Delete the onBackPressed() code, no need to handle it.

Answer 4

Each time in onBackPressed()method you are starting a new Activity and android works on Backstack Model..

Let me explain this

Activity-A  Activity-B  Activity-C

So each time you are clicking OnBackPressed the stack is showing this behaviour.

Stack [ Activity-A, Activity-B, Activity-C,(Backpressed)(POP Activity-C), Activity-B, Activity-C, (Backpressed)(POP - Activity-C), Activity - B, Activity - C, (BackPressed)(POP - Activity-C), Activity - B, Activity -C...]

So Remaining Stack will be like

Stack [ Activity-A, Activity-B, Activity-B, Activity - B, Activity - B, Activity -C...]

Just call finish(); not new Intent.
