Hi all,
I want to customize a permission for a service in Framework. The service is
also customized by me, the implement's mechanism is IPC (aidl) and boots
with the device. And it checks permissions before apps call the service's
method. But the result of checking permissions is always failure:denied.
I define the permission in framework/base/core/res/Manifest.xml:
<permission android:name="com.android.permission.SIMCARD_AUTHENTICATION"
android:protectionLevel="dangerous" />
Service code:
private boolean checkPermissions() {
Log.d(TAG,"checkPermissions"+mContext.checkCallingOrSelfPermission(android.Manifest.permission.SIMCARD_AUTHENTICATION));
Log.d(TAG,"Binder.getCallingPid()="+Binder.getCallingPid()+"Binder.getCallingUid()="+Binder.getCallingUid());
if
(mContext.checkCallingOrSelfPermission(android.Manifest.permission.SIMCARD_AUTHENTICATION)
!= PackageManager.PERMISSION_GRANTED){
return false;
}
return true;
}
Note: the log info is always -1(denied) and the other is normal.
The manifest.xml of APPs:
<application>
<activity android:name="DefaultActivity" android:label="@string/unknown">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<use-permissions android:name
="com.android.permission.SIMCARD_AUTHENTICATION"></use-permissions>
Who can help me ? Thanks!
