recently I am stared using the IMX6 SABRE-AI board with Android 7.1.1. I have modified one of in built in android application(system application EX: Settings app) and compiled successfully to generate new apk with modifications.
Now I tried to push my new apk (settings_modified.apk) file in to /system/apps using adb but i am getting read only error. no write permissions to /system/app.
I have found to get rid of this error
1. my device should be rooted
2. sign the modified apk with OEM key
when i looked in to the NXP community suggesting rooting the device is not recommended.
when comes to the sigining the apk with OEM key, does NXP provide the OEM key by request?
is there way to solve this problem?
