Cheers, folks
I am trying to install an apk to my Nexus 5 with ROM from AOSP and I want
this .apk to have system uid on install. I know, that it must be signed by
platform certificate. It's an easy task when you have appropriate private
keys by your hand such as the case with AOSP, but what if you have some ROM
and don't have access platform certificate. I want my app to launch with
system uid on those ROMs either, so I decided to resign all platform-signed
apks with my own certificate in such third-party ROMs. I identified all
apks signed with platform certificate remove the META-INF directory from
inside of these apks and signed them with my cert using jarsigner. I have
also updated mac_permissions.xml file and inserted my platform cert there
instead of old one. After booting such ROM everything worked fine except
some apps crashed (especially NFC app constantly tried to initialize and
failed at resource loading). I could also sign my apk with my platform cert
and everything works fine, still these other apps crashing are bothering
me. Could someone please address me the right place, where ROM's platform
certs "have power" i mean where there signatures are check, maybe i missed
something.
I used for debugging AOSP 4.4.2 on Nexus 5
