Using startActivityForResult for multiple actions

Question

I am using startActivityForResult for two actions like this

Activity A -> startActivityForResult(ActivityB,0) -> Activity B -> setresult(10); finish(); -> Activity A -> if(result==10) {dofunction(); } 

but I have to use this logic for 4 or more operations.

 Activity A -> startActivityForResult(ActivityB,0) -> Activity B -> finish(); -> Activity C -> finish(); -> Activity D -> setresult(10); finish(); -> Activity A -> if(result==10) {dofunction(); } 

but it does not work.

Answer 1

DECISION:

 Activity A -> startActivityForResult(activityB,0); Activity B -> activityCintent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(activityCintent); finish(); Activity C -> activityDintent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(activityDintent); finish(); Activity D -> setresult(10); finish(); Activity A -> if(result==10) {dofunction(); } YEPPP 

this is the logic of FLAG_ACTIVITY_FORWARD_RESULT. First you start an action for the result, a new activity transfers this intention to another new action until you set the result. Hope this will be helpful for those facing the same issue.

After naming in startActivityForResult(ActivityB,0) we issue a request code for the specified activity, i.e. startActivityForResult(ActivityB,REQUEST_CODE_FOR_ACTIVITYB) . with request code - any integer. Then in onActivityResult check each request code and implement your logic
