"Go" to completely resolve install_failed_update_incompatible installation errors

Use the ADB shell to enter the system, enter/data/app or/data/data, delete the same package name as the apk you installed;
Press CTRL + C to exit the system, use the ADB pull/data/system/packages.xml command to place the Packages.xml on your PC locally, and then find the package name you need to delete to a piece of data. For example:

1. <package name= "Com.android.wallpaper" codepath= "/system/app/livewallpapers.apk" nativelibrarypath= "/data/data/ Com.android.wallpaper/lib "flags=" 1 "ft=" 11b7e237e00 "it=" 11b7e237e00 "ut=" 11b7e237e00 "version=" ten "userId=" 10012 " ><sigs count= "1" >
2. <cert index= "2"/>
3. </sigs>
4. </package>

Copy Code

Save the Packages.xml, and then ADB push Packages.xml/data/system sends the Packages.xml file back to the device.
Then re-install your apk file again to see if success.

Add:

ADB shell

cd/data/app/, delete apk file Rm-rf xxx

cd/data/data/, delete apk file Rm-rf xxx
