Hi Job.Bao,
packages/apps/mind_game/AndroidManifest.xml:1: error: Error parsing XML: not well-formed (invalid token)
The above mentioned is the error I am facing right now.
In AndroidManifest.xml I added the following line as mentioned in the Quectel document
android:sharedUserId="android.uid.system"

@kevinzhang2020 could you give me a hand?
