Android FrameProcessor method close() will crash

[solmate-james]

I use face detection and hair segmentation, both of which work when used alone.
My situation is that face detection is turned on in Activity, and there is a Bottom Navigation Bar at the bottom of the screen. When you click on it will switch Fragment.
After entering Fragment will turn on hair segmentation, but the App will crash.

com.google.mediapipe.framework.MediaPipeException: not found ValidatedGraphConfig Initialization failed

I think the implementation of FrameProcessor is caused by singleton.
So I want to close the FrameProcessor before entering the Fragment
But it will crash directly when I call it.

How do I use FrameProcessor close() well?

#1555 #580
I have confirmed the above two questions. It seems that they only use one model, so they can singleton FrameProcessor, but I have to set a different mobile_gpu.binarypb in new FrameProcessor(), the situation is different.

I have found a similar issue, Could you please verify with this. If the reference doesn't work, please provide the below details.

Assuming the above issue is often due to finding the calculator dependencies. Can you provide all the steps to reproduce the above error. With respective details like android phone and its version.

@sgowroji
I think #1450 has no way to help me solve it. He seems to be misplaced aar.

I use a simple example to replicate the processor.close() crash problem.
https://github.com/jiuqiant/mediapipe_face_detection_aar_example
I cloned the above code, and only added a button to the xml. When I click it, I call processor.close() and it will crash.

activity_main.xml
Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="processor.close()"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"

MainActvitiy.java
Button button = findViewById(R.id.button);
button.setOnClickListener(view -> {
if (processor != null) processor.close();
});

My Android phone is Samsung (Galaxy A8+), and the Android version is 9.0.
Thanks for your reply!

@camillol knows the FrameProcessor better than @mcclanahoochie and me. It's better to ask @camillol to take a look.
