Error while completing app created in Android Studio

When you enter a ImageView , and try to run the app on the emulator, it displays the following message on the screen: **com.android.phone has stopped** , plus this message disappears and it executes normally.

But when I run on the phone, it has the following error:

  

Caused by: android.content.res.Resources $ NotFoundException: Resource ID # 0x7f060056

Soon after that, close the application.
