Steps to Reproduce

In our application, we have only one flutter context(one FlutterView wrapped in multiple FlutterWrapperActivity), so the getBitmap will be called when I want to push/pop when switching activities.

However, in our test, we noticed that getBitmap will cause an abort will be triggered when I call the getBitmap for the FlutterView(which is singleton). The original abort code is given below:

  const SkISize& frame_size = layer_tree->frame_size();
  jsize pixels_size = frame_size.width() * frame_size.height();
  jintArray pixels_array = env->NewIntArray(pixels_size);
  FXL_CHECK(pixels_array);

It's located in platform_view_android.cc.
And the crash message is：
Abort message: '[FATAL:flutter/shell/platform/android/platform_view_android.cc(717)] Check failed: pixels_array.

From my point of view, I should call the FlutterView.getBitmap with a lock to avoid the reentry(as I have only one FlutterView). Or should the
void PlatformViewAndroid::GetBitmapGpuTask
avoid aborting when this situation happens.

Question:
How can I avoid the abort logic? Should I ensure that it's not reenterable or should the framework ensure that even I call it continously, it works fine.
