Did you push the qnn libraries to the device?
The onnxruntime needs the qnn library to execute models.

no, I haven't pushed anything. I just added the libQnnHtp.so in jnilibs folder in android. Can you share a little more details about which libraries are needed and what would be the absolute path to push these in?

Hi, under which path of the device does the library need to be placed?

from onnxruntime.

I used the following official demo code to push the library, but encountered the error with HTP backend Android 8Gen2 device. "QNN SetupBackend failed: Failed to create device. Error: 14001".
std::vector<const char*> options_keys = {"backend_path"};
std::vector<const char*> options_values = {"/data/user/0/com.example.myapplication/cache/libQnnHtp.so"};

However, the official demo run_qnn_ep_sample.bat file includes multiple libraries:

1. libQnnHtp.so
2. libQnnHtpV73Stub.so
3. libQnnHtpV73Skel.so
4. libQnnHtpPrepare.so
5. libqnnhtpv73.cat
6. libQnnCpu.so
7. libQnnSystem.so

I also tried using options_values.push_back("/data/user/0/com.example.myapplication/cache/*.so"), or copied these *.so files to the cache folder (the same folder as libQnnHtp.so), but it still failed.

How can I provide these libraries to the device to successfully run the HTP backend on Android device?

Build Info:

• libonnxruntime.so = 1.18
• QNN SDK = 2.22*

I just export the library path using the LD_LIBRARY_PATH.
Linux(android) occurs the fault without the libary, they are searching some folders. such as /vendor/lib64, /sytem/lib64 ....
It depends on the systems. As I set the LD_LIBARY_PATH, it also search the library in LD_LIBRARY_PATH.

$ export LD_LIBRARY_PATH="/data/user/0/com.example.myapplication/cache/"
