My parent class open a child activity correctly but when i tried to close this child activity with this.finish() or getCurrentActivity().finish() i get a force close error. I know using getParent().finish() will close the parent activity, so, this means it is feasible to close child activity.
I search and come to getLocalActivityManager(). i believe this is the key to close a child activity in a tab group. But how to apply this ? I am trying but its fruitless.
here is my method to close the child activity.
public void onClick(View v) {
switch(v.getId()){
case R.id.back:
final LocalActivityManager manager = getLocalActivityManager();
manager.getCurrentActivity().finish();
break;
}
}
