[Android 14/15/16] TensorFlow Lite GPU delegate not supported? (ObjectDetection demo issue)

hank2024 — Mon, 10 Nov 2025 09:22:50 GMT

Hi,

I have been testing the TensorFlow Lite Object Detection demo on several Android BSP releases for the i.MX8MQ EVK, but the GPU delegate cannot be enabled successfully.
The inference works correctly on CPU, but when switching to GPU delegate, initialization fails and inference does not start.

Test Environment

Item Version / Detail

SoC	NXP i.MX8MQ
Android BSP	android-16.0.0_1.0.0 / android-15.0.0_2.0.0 / android-14.0.0_1.2.0
Demo	TensorFlow Lite Object Detection (from TensorFlow)
GPU	Vivante GC7000Lite
NPU	Not used

Problem Details

The app runs fine with CPU inference, but when enabling GPU delegate, it fails to initialize.
Here are some of the relevant logcat messages during GPU mode:

2025-09-11 20:05:58.595 libEGL E call to OpenGL ES API with no current context (logged once per thread) 2025-09-11 20:05:55.994 Surface E IGraphicBufferProducer::setBufferCount(0) returned Invalid argument 2025-09-11 20:05:56.086 BaseTaskApi W Closing an already closed native lib

in the code:

if (CompatibilityList().isDelegateSupportedOnThisDevice) { baseOptionsBuilder.useGpu() activeDelegate = "GPU" } else { objectDetectorListener?.onError("GPU is not supported on this device") // also print this !!!!!!!!!!!! }

I have check:

In /vendor/lib64/, there are libraries such as libOpenCL.so, libtim-vx.so,

Is direct GPU Delegate unsupported on i.MX8MQ even in Android BSP? (Similar to this Android 13 thread, where VX was recommended for Android 14+.)

Hi hank:

The stock TFLite GPU delegate is not supported on i.MX8MQ Android BSPs , this is expected due to GPU backend compatibility and NXP's chosen acceleration strategy. Use VX (TIM-VX) delegate on i.MX8M, and Neutron delegate on i.MX95.

Thank you very much for your reply. I have already resolved the issue. I also referred to this document. i.MX TensorFlow Lite on Android User's Guide
