Solve permission denied error when using SystemProperties.set()

[B Sampath Kumar]

Hi,

I’ve a problem of not having enough permissions for setting a “persist.xxxxx” property from one of the applications. This application shares the UserId of the phone so I tried to hack in property_service.c and add an entry:

 

{“persist.”, AID_RADIO, 0}

 

in property_perms structure.

 

After this I was able to set the property but without this I get a “permission denied” error.

Does anyone know how to solve permission denied error ?

Btw, I get this error: "> init: sys_prop: permission denied uid:1001  name:persist.xxxxx"

as you have already hacked property_service.c, uid 1001 is AID_RADIO, so why not change the key of your porperty_set call, eg:from persist.xxxxx to persist.radio.xxxxx?
