title: Android errors/warnings in emulator or on device: which can I ignore?
body: <p>This question is similar to, but not the same as, <a href="https://stackoverflow.com/questions/4965339/logcat-errors-when-running-android-emulator">Logcat errors when running android emulator</a>.</p>
  
  <p>When I run my app on the emulator, or even on the device, there are errors or warnings that I can apparently safely ignore. For example, see <a href="https://stackoverflow.com/questions/1114199/missing-opengl-drivers-on-android-emulator">Missing OpenGL drivers on Android emulator</a>.</p>
  
  <p>How can I accurately identify which errors/warnings are real and signifying a problem, and which can be ignored? I'm guessing the solution is either</p>
  
  <p>1) a list of known messages/issues I can ignore, or</p>
  
  <p>2) some sort of rule about which sources of the errors/warnings can be ignored (e.g. "if the logcat entry has tag X, you can ignore that")</p>
  
  <p>I believe that living with spurious errors/warnings is dangerous, because you're more likely to miss real problems.</p>
