Cannot connect to keystore #34

Cannot connect to keystore android.os.DeadObjectException
at android.os.BinderProxy.transactNative(Native Method)
at android.os.BinderProxy.transact(Binder.java:617)
at android.security.IKeystoreService$Stub$Proxy.begin(IKeystoreService.java:1255)

This mistake happens occasionally. The wrong place is the 496th line of EncryptionManager.
