When I run my Android App I get the following error:

  • Are you using `MapViewFragment` in your code? I am having a similar error in mine, trying to inflate it from XML. – IgorGanapolsky Mar 15 '16 at 17:50

Could you share your code? Did you use the emulator to run your app or a phisical device?

Because there may be many reasons:

  1. You have opened something but never close them. Closable has a close() method which you must call to manually release the opened resources associated with the component when you no longer need it (for example in a finally block).

  2. Also, that error message shows up when there is a problem in AndroidManifest.xml. For example when the <activity> tag accidentally went out of <application>

  3. Emulators have StrictMode on by default, on real devices it can be turned on in code via:

Code:

StrictMode.setVmPolicy (new StrictMode.VmPolicy.Builder().detectAll().penaltyLog()
                                          .penaltyDeath().build());
