Re: Security help

[Christopher Tate]

The very first line of the error log that you pasted:

> E/ServiceManager( 533): add_service('simphonebook',0x2b) uid=10006 -
> PERMISSION DENIED

tells you that your application is not running as the system user,
which would be uid 1000. Only system apps are allowed to register
system services. To have your application run as the system user, its
manifest needs to declare android:sharedUserId="android.uid.system".

I also see that you have a class
com.android.smithmyers.mobilepowersurvey.MobilePowerSurvey -- you
really should not put non-Android classes into the com.android.*
package namespace. This should probably be com.smithmyers.* instead.
