NullPointerException

[AntonLunegovPerm]

Hello! I'm ran into with some error. When I'm enter the symbols by keyboard, sometimes I'm get a crash like this.

E/AndroidRuntime: FATAL EXCEPTION: Thread-14 Process: com.pa.mango, PID: 19742 java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a null object reference at com.android.tools.profiler.support.profilers.EventProfiler$InputConnectionHandler.run(EventProfiler.java:316) at java.lang.Thread.run(Thread.java:764)

My XML-file is:
