Well. Ran into an issue with my patch. Getting this issue when the opening up Wallet. I tried using the previous hacks but something seems wrong. Willing to listen to ideas.
EDIT: Seems like it may have something to do with the way that I'm signing the apk. Figures. Logcat mentions /etc/nfcee_access.xml limiting access to the secure element. I suppose that with the test-keys error is causing the app to fail. Again, open to suggestions.
EDIT 2: So I'm going to put this down for a bit since I can't figure out the signing thing. I've included two apks. The "signed" can be placed in /system/app and will open giving the attached error. The other one isn't signed so it won't run on your phone. If someone can figure out that last bit I'm fairly sure that patches that I put in place should work.
