title: Getting ResourceNotFoundException after device rebooted
body: <p>I am having Boot Completed Receiver in my application and after Reboot completed, inside my Boot Receiver I am starting an Activity. In that I am getting ResourceNotFoundException on setting layout.</p>
  
  <pre><code>setContentView(R.layout.activity_home);//getting error of resource not found on this line
  </code></pre>
  
  <p>I don't know the reason but its but obviously because it is not able to find the layout or R in my app.
  Anyone has any idea about this? Please kindly guide me to resolve this issue.</p>
  
  <p><strong>EDIT - I found that if I unlock the screen before my app try to load then it will not having any problem. Problem is only occurred when the emulator screen is locked and I unlock it after my app starts. So what happens it shows me the message the your app is unfortunately crashed.</strong></p>
