title: activity's life cycle is beyond its application process?
body: <p>I got a main-activity, then it opened a new-activity. After putting it to background by clicking home button. If I killed the process using adb shell commands, then I reopen my app. </p>
  
  <p>The new-activity is shown by default instead of starting from the first activity. 
  <br></p>
  
  <p>My question is that activity's life cycle is beyond its application process? 
  As the sample shows, even activity's application process is killed, the saved activity still is there. Is this correct? And will android system recycle the saved activities later? </p>
