Android tips: Turn your app into an app that comes with the mobile phone system [/system/APP]

How to put your favorite app into the system app is actually very simple, only two operations are required

1. Root the phone first. This step is a prerequisite.

2. If you use the File Manager, you need to copy your favorite app to the/system/APP directory directly. Remember to read and write the/system/APP

If you use the ADB shell command to play the game, it will be simpler,

ADB push local directory/xx.apk/system/APP

Of course, many people will encounter some problems, such:

Failed to copy 'C: \ Users \ changeself \ downloads \ google service \ rootexplorer_v2.12h.apk 'to'/system/APP/rootexplorer_v2.12h.apk ': Read-Only File System

"Read-Only File System" indicates that you/system/APP have the read-only permission. Therefore, you cannot create files on it, the copy operation actually creates a file in that directory.

To solve this problem, run the mount command:

ADB shell Mount-O remount, RW-T yaffs2/dev/block/mtdblock0/System
