title: Application not open main activity when it was killed after pressing home button in android
body: <p>In my Application, activity A is launcher activity, from A it called B and from B it called C, I have such more than 5 activities. In C when I press home button, and again open my app it open C, that is fine in my case. But after pressing home button in C, when it idle for some time and application is killed, after that when I open my app it opens C. But I want to open main launcher activity that time. How can I do this?</p>
  
  <p><strong>A > B > C > HOME button > idle for some time > application killed > open app > C.</strong></p>
  
  <p><strong>In this case I want to open main activity A instead of C.</strong></p>
