I am using IMX6 SABREAUTO-AI board with Android 7.I wanted to customize the android system application,after modifying the android system app (ex : Contacts app),I compiled only that application to get the apk file with modification what i have done(using "mm -b" command).
I tried to push the apk file into "system" folder using
adb push <apk file path> /system/app
now i am getting the read only file system error.
to change the permissions for "system" folder every one saying device should be rooted
is it possible to root the my nxp board? if possible what is better solution with out breaking the board?
in the Android_User's_Guide.pdf mentioned that,if the build type is "userdebug" it provides image with root access and debug, similar to "user".
I have tried the usedebug build variant also ,but getting same error "read only file system" when i try to push the apk file in to /system/app
