nit: you can move this to private

[qinmin, 2013/09/23 16:19:03]

or just remove the function and merge it with the native jni call

Done. (move to private)

+  void ResetCredentials(JNIEnv* env, jobject obj, jobject callback);
+
+  static bool RegisterMediaDrmCredentialManager(JNIEnv* env);
+
  private:
+ ~MediaDrmCredentialManager();

   // Callback function passed to MediaDrmBridge. It is called when reset
   // completed.
   void OnResetCredentialsCompleted(const std::string& security_level,
                                    bool success);
 
   // Reset DRM credentials for a particular security level. Returns false if
   // we fail to create the MediaDrmBridge, or true otherwise.
   bool ResetCredentialsInternal(const std::string& security_level);
 
   // The MediaDrmBridge object used to perform the credential reset.
   scoped_ptr<media::MediaDrmBridge> media_drm_bridge_;
 
   // The callback provided by the caller.
   ResetCredentialsCB reset_credentials_cb_;
 
   DISALLOW_COPY_AND_ASSIGN(MediaDrmCredentialManager);
 };
 
 }  // namespace content
