Clear all actions except one in android

Question

Below I show how I want to navigate through Activities:

I tried to write the following code inside Dand E:

Intent list = new Intent(AddComplaint.this, B.class);
list.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(list);

However, I ran into two problems:

• When it starts B, a gray screen is displayed for a while, then it loads.
• When I get back from B, it exits the application, and does not go to A(dashbord).

How can i fix this?
