[Bug report] Crash on Pixel 6 / 6 Pro with pose-detection-accurate:18.0.0-beta5

[thanhlucnguyen]

Describe the bug
App crashes with a native JNI error (fid == null) when using ML Kit Pose Detection (accurate) version 18.0.0-beta5.

The crash happens immediately on app startup, even before any ML Kit API is explicitly called.

This issue only occurs on Pixel 6 / Pixel 6 Pro (Tensor) and is reproducible across multiple Android versions (12 and 13), while other devices (including Pixel 6a) work normally.

To Reproduce

• Add dependency:
  implementation "com.google.mlkit:pose-detection-accurate:18.0.0-beta5"
• Build and run the app on Pixel 6 or Pixel 6 Pro
• Launch the app
• App crashes immediately on startup

Error:

JNI DETECTED ERROR IN APPLICATION: fid == null
in call to GetObjectField

Relevant stacktrace:

com.google.mlkit.vision.mediapipe.MediaPipeGraphRunner.load
com.google.mlkit.vision.pose.internal.zzh.load
com.google.mlkit.common.sdkinternal.ModelResource.zza
com.google.mlkit.common.sdkinternal.MlKitThreadPool

Expected behavior
The app should start normally without crashing, and ML Kit should initialize safely in the background.

SDK Info:

• com.google.mlkit:pose-detection-accurate:18.0.0-beta5

Note:

• Version 18.0.0-beta3 works correctly (no crash), but it does not support Android 16KB page size, so upgrading to beta5 is required.

Smartphone:

• Device: Pixel 6, Pixel 6 Pro (crash)
• OS: Android 12 (API 31), Android 13 (API 33)

Not affected:

• Pixel 6a
• Other Android devices
