I'm building a small quiz app with 3 activities A, B, C. A startActivity() to B. B has a fragment B_frag to show the quiz detail, after finish the quiz B_frag will startActivity() to C which is the result activity. C has an option to redo the quiz which will startActivity() to B again, this time with a string through intent.putExtra(). The problem is nothing comes out of the intent.getStringExtras() on activity B after being called from C. Can someone pls tell me why this happens and how to fix it?

From the Activity C try to use FLAG_ACTIVITY_SINGLE_TOP when you call startActivity() to start Activity B. Then in Activity B override onNewIntent() to get the new intent from Activity C.

Show us some code.
For sending data from Activity A to Activity B, try this:
intent.putExtra("someKey", yourView.getText().toString());
In Activity B:
Bundle bundle = getIntent().getExtras();
if (bundle!=null){
yourString= bundle.getString("someKey", "no name");
}
yourView.setText(yourString);

Setting `Intent.FLAG_ACTIVITY_NEW_TASK` is completely useless when you call `startActivity()` from one of your own activities, as the `Activity` will always be launched into the current task (unless you have explicitly set `taskAffinity` in the manifest. Also, this flag has no effect whatsoever on extras in the `Intent`. – David Wasser Oct 06 '16 at 14:43
