Android Studio JNI detected error in application

[sufiaji]

Hi team,

I added output_stream:"DETECTIONS:output_detections" in file face_detection_mobile_gpu.pbtxt and generate AAR so that I can get face landmark (eyes, nose, mouth) in Android Studio. Application successfully started but within few seconds it crashes with below error in Android Studio logcat.

Did I miss something?
Thank you

Hi team,

Same error when tried to run object detection. App successfully started on my Android device but then few seconds later it crashed with same message:

JNI DETECTED ERROR IN APPLICATION: JNI GetObjectClass called with pending exception java.lang.NoClassDefFoundError: com.google.mediapipe.formats.proto.DetectionProto$Detection
at com.google.protobuf.Parser com.google.mediapipe.formats.proto.DetectionProto$Detection.parser() (DetectionProto.java:2530)
........

This time I didn't change any files related to object detection since the functionality of output stream callback already there.
Thank you.

Hi,
I really need your help please... Been working for almost 1 week to solve this issue but no clue :(
Thank you

Hi,

Problem solved. Implement protocol buffer full version (not lite) in Gradle solved the issue. Apparently the method being called in GetProtoVector is not exist in protobuf lite version.
Thanks!
