Hi all,

  I am using <uses-permission

                android:name="android.permission.ACCESS_SURFACE_FLINGER" />

to access the ISurface, But I am getting the error: 

E/SecHardwareRenderer(  424): iSurface is get

E/SecHardwareRenderer(  424): mframesize set  ok

W/ServiceManager(   90): Permission failure: android.permission.ACCESS_SURFACE_FLINGER from uid=10036 pid=424

E/SurfaceFlinger(   90): Permission Denial: can't access SurfaceFlinger pid=424, uid=10036

you might miss to set the device graphics group.

for example, /dev/graphics/* is belong to graphics group. as a result, SF will have permission to access it. 

refer to ueventd.rc

/dev/graphics/*           0660   root       graphics

thanks,

Thanks for your reply. Default my /dev/graphics/* is belong to graphics group. 

I change the android.permission.ACCESS_SURFACE_FLINGER permission protectionLevel from signature to normal in frameworks/base/core/res/AndroidManifest.xml file, it fixed the permission problem, although it's a bad idea.

Finally We add same interface in MediaPlay, solve our problems.

# cd /dev/graphics

# ls -l
