  1.     204 if (inputEventObj) {
  2.     208     env->CallVoidMethod(mReceiverObjGlobal,
  3.     209          gInputEventReceiverClassInfo.dispatchInputEvent, seq, inputEventObj);
  4.     210     if (env->ExceptionCheck()) {
  5.     211         ALOGE("Exception dispatching input event.");
  6.     212         skipCallbacks = true;
  7.     213     }
  8.     214         env->DeleteLocalRef(inputEventObj);
  9.     215 } else {
  10.     216      ALOGW("channel '%s' ~ Failed to obtain event object.", getInputChannelName());
  11.     217     skipCallbacks = true;
  12.     218 }
