Problem

I am following the guide of the README.md

when I traced the problem I found it occurs in .withConnectableCallbacks() .clear() in clearRegistrations() in Registrar class is run

java.lang.RuntimeException: Unable to pause activity......... Caused by: java.lang.NullPointerException at com.novoda.merlin.registerable.Registrar.clearRegistrations(Registrar.java:65) at com.novoda.merlin.Merlin.unbind(Merlin.java:30) at com.example.android.onegreatpost.MainActivity.onPause(MainActivity.java:155) at android.app.Activity.performPause(Activity.java:5426) at android.app.Instrumentation.callActivityOnPause(Instrumentation.java:1244) at android.app.ActivityThread.performPauseActivity(ActivityThread.java:3304) at android.app.ActivityThread.performPauseActivity(ActivityThread.java:3273)  at android.app.ActivityThread.handlePauseActivity(ActivityThread.java:3251)  at android.app.ActivityThread.access$1300(ActivityThread.java:143)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1279)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:136)  at android.app.ActivityThread.main(ActivityThread.java:5356)  at java.lang.reflect.Method.invokeNative(Native Method)  at java.lang.reflect.Method.invoke(Method.java:515)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:864)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:680)  at de.robv.android.xposed.XposedBridge.main(XposedBridge.java:133)  at dalvik.system.NativeStart.main(Native Method) 

Potential Solution

I might be make use .withBindableCallbacks() & .withDisconnectableCallbacks() for now
or fix it from the clearRegistrations() and check null values becfore clearing

Thanks in advance
