Android Question android uid system INCOMPATIBLE and system signature


New Member
Hello to all . I have been involved in this issue for two weeks and I could not solve it. I will be happy to help you.
I use this code in my manifesto:
android: sharedUserId = "android.uid.system"
But when I use aosp signatures for my signature app. And I use Signapp.Jar to build my own Sign app. It gives the following error when running:
I had a few questions:
1: Where can I find Signapp.jar?
2: Where is this route? It is mentioned in various sites:
out / host / linux-x86 / framework / signapk.jar
3: I use the platform keys in the aosp to do this. Is this correct?
