IllegalAccessError / conflict with GCM 8.3.0 library

Hi,

First, thanks for all, I love your library and it's working good with a new project :)

When I add the library in an old project, after the compilation I have this error :

FATAL EXCEPTION: IntentService[GCM] Process: my.app, PID: 7667 java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.()' is inaccessible to class 'com.google.android.gms.iid.zzd' (declaration of 'com.google.android.gms.iid.zzd' appears in /data/app/my.app-1/base.apk:classes2.dex) at com.google.android.gms.iid.zzd.zzdL(Unknown Source) at com.google.android.gms.iid.zzd.(Unknown Source) at com.google.android.gms.iid.zzd.(Unknown Source) at com.google.android.gms.iid.InstanceID.zza(Unknown Source) at com.google.android.gms.iid.InstanceID.getInstance(Unknown Source) at gcm.RegistrationIntentService.onHandleIntent(RegistrationIntentService.java:54) at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:67) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.os.HandlerThread.run(HandlerThread.java:61)

This is the line of the problem :

InstanceID instanceID = InstanceID.getInstance(this);
I have look the reason of this error and it seem it's because I use a version too old of my play-services.

compile 'com.google.android.gms:play-services:8.3.0'
But it's working without adding the lib wisefy so how can I isolate this problem because I don't want to update my library ?

Oh! Interesting...yes, there is a conflict that is coming from the compile 'com.android.support:appcompat-v7:25.3.1' in WiseFy. I don't think we actually need the support libraries for anything at this time, so I'm okay with removing it for now until it's actually in use.

I'll push an update, but an alternative would be to exclude the version of appcompat-v7 that WiseFy is bringing in.

Thanks a lot !
How can I exclude the version of appcompat-v7 that WiseFy is bringing in ?

This should do it until I release 1.0.10:

compile ('com.isupatches:wisefy:1.0.9') {
      exclude module: 'appcompat-v7'
}

Thanks for reporting everything :)

Thanks it's working :)

Should be okay in 1.0.10 as well
