Alternative to system server.

[Rohit Rao]

Hello,

I developed a system service process on content generated by user apps, but realized that 
system servers do not have access to location 

a) data/data/<app package name> 

b) sdcard/Android/data/<app package name>

however has access to read and write at data/data but apps cannot write.

Is there any alternative other than system service which have following properties

1) Executes in the background

2) Available for the lifecycle of the device.

3) World permission(read/write).

Alternatively is possible to give permissions for the system server to read and write at the above mentioned locations.  

Any inputs/tips would be really helpful

Thank you,
