Google Play商店当机

Question

For a few days the Play store is crashing every time I try to open it and I even get the message when I'm not using it. It's very annoing so I looked for what was going wrong. I looked at the logcat and I found that there was a problem with the finsky.xml file.

Couldn't rename file /data/user/0/com.android.vending/shared_prefs/finsky.xml to backup file /data/user/0/com.android.vending/shared_prefs/finsky.xml

So I looked to this file with the shell and I found that there is problems with the permissions.

So I tried to fix the permissions but it wasn't successful.

>chown u0_a178:u0_a178 finsky.xml                                              
chown: 'finsky.xml' to 'u0_a178:u0_a178': Operation not permitted

>chmod 660 finsky.xml
chmod: chmod 'finsky.xml' to 100660: Operation not permitted

I did all of these commands with the root shell.

Is someone there that have an idea of what going with this file ?

Thank you, Louis.

Answer 1

I found the solution. I used :

chattr -AacdDijsStu finsky.xml

After that I could remove the file so Google play started working normally.
