ARC Welder: “Device does not have package com.google.android.gsf” despite “usePlayServices”: [“gcm”]
In my apk running in ARC welder I get: java.lang.UnsupportedOperationException: Device does not have package com.google.android.gsf at com.google.android.gcm.GCMRegistrar.checkDevice(GCMRegistrar.java:98) I get this despite having the following in Additional Metadata: { "usePlayServices": ["gcm"], "crx_key": ... } .
