Research direction

Start with mobile/examples/phi-3/android and inspect MainActivity.java, SimpleGenAI.generate, and the model files expected in the app's external-files directory. Compare the Qwen model inputs and past_key_values dimensions with the Phi-3 example and verify the tokenizer and model assets used by the demo. Done means the documented model setup runs without the reported tokenizer or dimension errors.

Written by the indexing model from the issue text.

Description

I use the demo which is onnx-runtime/onnxruntime-inference-examples/mobile/examples/phi-3/android , but I use the qwen model which is https://huggingface.co/onnx-community/Qwen2.5-0.5B-Instruct/tree/main to instead of the phi-3. Then I push the model_uint8.onnx file to the android phone. When I run the process，it occur some error below:

Here is the code :
`try {
Log.d(TAG, "start generator result");
SimpleGenAI generator = new SimpleGenAI(getExternalFilesDir(null).getPath());

                        GeneratorParams params = generator.createGeneratorParams();
                        params.setSearchOption("max_length", 20);
                        ByteBuffer data = ByteBuffer.allocateDirect(4 * Float.BYTES).order(ByteOrder.nativeOrder());
                        FloatBuffer floatBuffer = data.asFloatBuffer();
                        floatBuffer.put(new float[] {1.0f, 2.0f, 3.0f, 4.0f});
                        Tensor tensor = new Tensor(data, new long[]{64, 64}, Tensor.ElementType.uint8);
                        params.setInput(promptQuestion, tensor);
                        String result =
                                generator.generate(params, promptQuestion, null);
                        Log.d(TAG, "Result: " + result);
                        runOnUiThread(() -> {
                            generatedTV.setText(result);
                            sendMsgIB.setEnabled(true);
                            sendMsgIB.setAlpha(1.0f);
                        });

                    } catch (GenAIException e) {
                        e.printStackTrace();
                        Log.d(TAG, "GenAIException..");
                    }`

I don't know how to fix this error. Could anyone help me to fix this error? Thanks a lot.
