重新创建活动时，Android Volley不会从服务器加载数据

Question

I have three Activities, namely A, B and C.

Activities A and C are FragmentActivities

Finishing from Activity B is fine, since Volley will work properly in Activity A.

Same thing when finishing Activity C.

However, when I want to go from Activity C to A, I have to destroy B. It worked, but the problem is, I received no data from Volley when loading to Activity A.

Answer 1

Add these flags when starting activity A

    Intent intent = new Intent(this, ActivityA.class)
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);

and add flag in manifest also

    android:launchMode="singleTask"

you will be getting new callback onNewIntent(Intent intent) if you want to send any data
