+
+## Overview
+
+It is recommended that you start from the image classification demo on the Android device to understand how to build the MindSpore Lite application project, configure dependencies, and use related APIs.
+     
+This tutorial demonstrates the on-device deployment process based on the image classification sample program on the Android device provided by the MindSpore team.  
+
+1. Select an image classification model.
+2. Convert the model into a MindSpore Lite model.
+3. Use the MindSpore Lite inference model on the device. The following describes how to use the MindSpore Lite C++ APIs (Android JNIs) and MindSpore Lite image classification models to perform on-device inference, classify the content captured by a device camera, and display the most possible classification result on the application's image preview screen.
+   
+> Click to find [Android image classification models](https://download.mindspore.cn/model_zoo/official/lite/mobilenetv2_openimage_lite) and [sample code](https://gitee.com/mindspore/mindspore/tree/r0.7/model_zoo/official/lite/image_classification).
+
+## Selecting a Model
+
+The MindSpore team provides a series of preset device models that you can use in your application.  
+Click [here](https://download.mindspore.cn/model_zoo/official/lite/mobilenetv2_openimage_lite/mobilenetv2.ms) to download image classification models in MindSpore ModelZoo.
+In addition, you can use the preset model to perform migration learning to implement your image classification tasks. 
+
+## Converting a Model
+
+After you retrain a model provided by MindSpore, export the model in the [.mindir format](https://www.mindspore.cn/tutorial/en/r0.7/use/saving_and_loading_model_parameters.html#mindir). Use the MindSpore Lite [model conversion tool](https://www.mindspore.cn/lite/tutorial/en/r0.7/use/converter_tool.html) to convert the .mindir model to a .ms model.
+
+Take the mobilenetv2 model as an example. Execute the following script to convert a model into a MindSpore Lite model for on-device inference.
+```bash
+./converter_lite --fmk=MS --modelFile=mobilenetv2.mindir --outputFile=mobilenetv2.ms
+```
+
+## Deploying an Application
+
+The following section describes how to build and execute an on-device image classification task on MindSpore Lite.
+
+### Running Dependencies
+
+- Android Studio 3.2 or later (Android 4.0 or later is recommended.)
+- Native development kit (NDK) 21.3
+- CMake 3.10.2
+- Android software development kit (SDK) 26 or later
+- OpenCV 4.0.0 or later (included in the sample code)
+
+### Building and Running
+
+1. Load the sample source code to Android Studio and install the corresponding SDK. (After the SDK version is specified, Android Studio automatically installs the SDK.) 
+
+    ![start_home](../images/lite_quick_start_home.png)
+
+    Start Android Studio, click `File > Settings > System Settings > Android SDK`, and select the corresponding SDK. As shown in the following figure, select an SDK and click `OK`. Android Studio automatically installs the SDK.
+
+    ![start_sdk](../images/lite_quick_start_sdk.png)
+
+    (Optional) If an NDK version issue occurs during the installation, manually download the corresponding [NDK version](https://developer.android.com/ndk/downloads) (the version used in the sample code is 21.3). Specify the SDK location in `Android NDK location` of `Project Structure`.
+
+    ![project_structure](../images/lite_quick_start_project_structure.png)
+
+2. Connect to an Android device and runs the image classification application.
+
+    Connect to the Android device through a USB cable for debugging. Click `Run 'app'` to run the sample project on your device.
+
+    ![run_app](../images/lite_quick_start_run_app.PNG)
+
+    For details about how to connect the Android Studio to a device for debugging, see <https://developer.android.com/studio/run/device>.
+
+3. Continue the installation on the Android device. After the installation is complete, you can view the content captured by a camera and the inference result.
+
+    ![result](../images/lite_quick_start_app_result.jpg)
+
+
+## Detailed Description of the Sample Program  
+
+This image classification sample program on the Android device includes a Java layer and a JNI layer. At the Java layer, the Android Camera 2 API is used to enable a camera to obtain image frames and process images. At the JNI layer, the model inference process is completed in [Runtime](https://www.mindspore.cn/lite/tutorial/en/r0.7/use/runtime.html).
+
+> This following describes the JNI layer implementation of the sample program. At the Java layer, the Android Camera 2 API is used to enable a device camera and process image frames. Readers are expected to have the basic Android development knowledge.

+
+### Configuring MindSpore Lite Dependencies
+
+When MindSpore C++ APIs are called at the Android JNI layer, related library files are required. You can use MindSpore Lite [source code compilation](https://www.mindspore.cn/lite/tutorial/en/r0.7/build.html) to generate the `libmindspore-lite.so` library file.
+
+In Android Studio, place the compiled `libmindspore-lite.so` library file (which can contain multiple compatible architectures) in the `app/libs/ARM64-V8a` (Arm64) or `app/libs/armeabi-v7a` (Arm32) directory of the application project. In the `build.gradle` file of the application, configure the compilation support of CMake, `arm64-v8a`, and `armeabi-v7a`.　　
+
+```
+android{
+    defaultConfig{
+        externalNativeBuild{
+            cmake{
+                arguments "-DANDROID_STL=c++_shared"
+            }
+        }
+
+        ndk{ 
+            abiFilters'armeabi-v7a', 'arm64-v8a'  
+        }
+    }
+}
+```
+
+Create a link to the `.so` library file in the `app/CMakeLists.txt` file:
+
+```
+# Set MindSpore Lite Dependencies.
+include_directories(${CMAKE_SOURCE_DIR}/src/main/cpp/include/MindSpore)
+add_library(mindspore-lite SHARED IMPORTED )
+set_target_properties(mindspore-lite PROPERTIES
+    IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/libs/libmindspore-lite.so")
+
+# Set OpenCV Dependecies.
+include_directories(${CMAKE_SOURCE_DIR}/opencv/sdk/native/jni/include)
+add_library(lib-opencv SHARED IMPORTED )
+set_target_properties(lib-opencv PROPERTIES
+    IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/libs/libopencv_java4.so")
+
+# Link target library.       
+target_link_libraries(
+    ...
+    mindspore-lite
+    lib-opencv
+    ...
+)
+```
+
+
+
+In this example, the  download.gradle File configuration auto download ` libmindspot-lite.so  `and  `libopencv_ Java4.so` library file,  placed in the 'app / libs / arm64-v8a' directory.
+
+Note: if the automatic download fails, please manually download the relevant library files and put them in the corresponding location.

+
+libopencv include [libopencv include]( https://download.mindspore.cn/model_zoo/official/lite/lib/opencv%204.4.0/include.zip)
+
+
+
+### Downloading and Deploying a Model File
+
+In this example, the  download.gradle File configuration auto download `mobilenetv2.ms `and placed in the 'app / libs / arm64-v8a' directory.
+
+Note: if the automatic download fails, please manually download the relevant library files and put them in the corresponding location.
+
+mobilenetv2.ms [mobilenetv2.ms]( https://download.mindspore.cn/model_zoo/official/lite/mobilenetv2_openimage_lite/mobilenetv2.ms)
+
+
+
+### Compiling On-Device Inference Code
+
+Call MindSpore Lite C++ APIs at the JNI layer to implement on-device inference.
+
+The inference code process is as follows. For details about the complete code, see `src/cpp/MindSporeNetnative.cpp`. 
+
+1. Load the MindSpore Lite model file and build the context, session, and computational graph for inference.  
+
+    - Load a model file. Create and configure the context for model inference.
+        ```cpp
+        // Buffer is the model data passed in by the Java layer
+        jlong bufferLen = env->GetDirectBufferCapacity(buffer);
+        char *modelBuffer = CreateLocalModelBuffer(env, buffer);  
+        ```
+        
+    - Create a session.
+        ```cpp
+        void **labelEnv = new void *;
+        MSNetWork *labelNet = new MSNetWork;
+        *labelEnv = labelNet;
+        
+        // Create context.
+        lite::Context *context = new lite::Context;
+        
+        context->device_ctx_.type = lite::DT_CPU;
+        context->thread_num_ = numThread;  //Specify the number of threads to run inference
+        
+        // Create the mindspore session.
+        labelNet->CreateSessionMS(modelBuffer, bufferLen, "device label", context);
+        delete(context);
+        
+        ```
+        
+    - Load the model file and build a computational graph for inference.
+        ```cpp
+        void MSNetWork::CreateSessionMS(char* modelBuffer, size_t bufferLen, std::string name, mindspore::lite::Context* ctx)
+        {
+            CreateSession(modelBuffer, bufferLen, ctx);  
+            session = mindspore::session::LiteSession::CreateSession(ctx);
+            auto model = mindspore::lite::Model::Import(modelBuffer, bufferLen);
+            int ret = session->CompileGraph(model);
+        }
+        ```
+    
+2. Convert the input image into the Tensor format of the MindSpore model. 
+
+    Convert the image data to be detected into the Tensor format of the MindSpore model.
+
+    ```cpp
+    // Convert the Bitmap image passed in from the JAVA layer to Mat for OpenCV processing
+    BitmapToMat(env, srcBitmap, matImageSrc);
+   // Processing such as zooming the picture size.
+    matImgPreprocessed = PreProcessImageData(matImageSrc);  
+
+    ImgDims inputDims; 
+    inputDims.channel = matImgPreprocessed.channels();
+    inputDims.width = matImgPreprocessed.cols;
+    inputDims.height = matImgPreprocessed.rows;
+    float *dataHWC = new float[inputDims.channel * inputDims.width * inputDims.height]
+
+    // Copy the image data to be detected to the dataHWC array.
+    // The dataHWC[image_size] array here is the intermediate variable of the input MindSpore model tensor.
+    float *ptrTmp = reinterpret_cast<float *>(matImgPreprocessed.data);
+    for(int i = 0; i < inputDims.channel * inputDims.width * inputDims.height; i++){
+       dataHWC[i] = ptrTmp[i];
+    }
+
+    // Assign dataHWC[image_size] to the input tensor variable.
+    auto msInputs = mSession->GetInputs();
+    auto inTensor = msInputs.front();
+    memcpy(inTensor->MutableData(), dataHWC,
+        inputDims.channel * inputDims.width * inputDims.height * sizeof(float));
+    delete[] (dataHWC);
+   ```
+   
+3. Perform inference on the input tensor based on the model, obtain the output tensor, and perform post-processing.    
+
+   - Perform graph execution and on-device inference.
+
+        ```cpp
+        // After the model and image tensor data is loaded, run inference.
+        auto status = mSession->RunGraph();
+        ```
+
+   - Obtain the output data.
+        ```cpp
+        auto msOutputs = mSession->GetOutputMapByNode();
+        std::string retStr = ProcessRunnetResult(msOutputs, ret);
+        ```
+        
+   - Perform post-processing of the output data.
+        ```cpp
+        std::string ProcessRunnetResult(std::unordered_map<std::string,
+                std::vector<mindspore::tensor::MSTensor *>> msOutputs,
+                int runnetRet) {
+        
+            // Get model output results.
+            std::unordered_map<std::string, std::vector<mindspore::tensor::MSTensor *>>::iterator iter;
+            iter = msOutputs.begin();
+            auto brach1_string = iter->first;
+            auto branch1_tensor = iter->second;
+        
+            int OUTPUTS_LEN = branch1_tensor[0]->ElementsNum();
+        
+            float *temp_scores = static_cast<float * >(branch1_tensor[0]->MutableData());
+        
+            float scores[RET_CATEGORY_SUM];
+            for (int i = 0; i < RET_CATEGORY_SUM; ++i) {
+                scores[i] = temp_scores[i];
+            }
+        
+            // Converted to text information that needs to be displayed in the APP. 
+            std::string retStr = "";
+            if (runnetRet == 0) {
+                for (int i = 0; i < RET_CATEGORY_SUM; ++i) {
+                    if (scores[i] > 0.3){
+                   retStr += g_labels_name_map[i];
+                        retStr += ":";
+                        std::string score_str = std::to_string(scores[i]);
+                        retStr += score_str;
+                        retStr += ";";
+                   }
+             }
+            else {
+                MS_PRINT("MindSpore run net failed!");
+                for (int i = 0; i < RET_CATEGORY_SUM; ++i) {
+                    retStr += " :0.0;";
+                }
+            }
+            return retStr;
+        }
