Android 4.3 added "AppOps" whitch is like permission manager.
Points
- added AppOpsManager, AppOpsService in the frameworks(Java Layer).
- If you would like to use "AppOps", you can called getSystemService(Context.LAYOUT_INFLATER_SERVICE).
- Each "Service" in frameworks decide to run operation, by obtaining a setting from the AppOpsService,
If you want to know more info, you should do grep "AppOpsManager.MODE_ALLOWED / MODE_IGNORED" in AOSP.
Create "AppOpsService" instance
AppOpsService is created in ActivityManagerService's constructor.
private ActivityManagerService() {
File systemDir = new File(dataDir, "system");
:
mAppOpsService = new AppOpsService(new File(systemDir, "appops.xml"));
:
}
Setting data of AppOpsManager
Setting data of AppOps is saved to xml file.
Xml file is named "appops.xml". It is saved under the System directory.
public class AppOpsService extends IAppOpsService.Stub {
public AppOpsService(File storagePath) {
mFile = new AtomicFile(storagePath);
mHandler = new Handler();
readState();
}
void readState() {
}
void writeState() {
}
}
