+# OCR文字识别 Android Demo 使用文档
+
+在 Android 上实现实时的OCR文字识别功能，此 Demo 有很好的的易用性和开放性，如在 Demo 中跑自己训练好的模型等。
+
+## 环境准备
+
+1. 在本地环境安装好 Android Studio 工具，详细安装方法请见[Android Stuido 官网](https://developer.android.com/studio)。
+2. 准备一部 Android 手机，并开启 USB 调试模式。开启方法: `手机设置 -> 查找开发者选项 -> 打开开发者选项和 USB 调试模式`
+
+## 部署步骤
+
+1. OCR文字识别 Demo 位于 `fastdeploy/examples/vision/ocr/PP-OCRv3/android` 目录
+2. 用 Android Studio 打开 PP-OCRv3/android 工程
+3. 手机连接电脑，打开 USB 调试和文件传输模式，并在 Android Studio 上连接自己的手机设备（手机需要开启允许从 USB 安装软件权限）

+</p>
+
+> **注意：**
+>> 如果您在导入项目、编译或者运行过程中遇到 NDK 配置错误的提示，请打开 ` File > Project Structure > SDK Location`，修改 `Andriod SDK location` 为您本机配置的 SDK 所在路径。
+
+4. 点击 Run 按钮，自动编译 APP 并安装到手机。(该过程会自动下载预编译的 FastDeploy Android 库 以及 模型文件，需要联网)
+   成功后效果如下，图一：APP 安装到手机；图二： APP 打开后的效果，会自动识别图片中的物体并标记；图三：APP设置选项，点击右上角的设置图片，可以设置不同选项进行体验。

+
+### PP-OCRv2 & PP-OCRv3 Java API 说明
+
+- 模型初始化 API: 模型初始化API包含两种方式，方式一是通过构造函数直接初始化；方式二是，通过调用init函数，在合适的程序节点进行初始化。 PP-OCR初始化参数说明如下：
+  - modelFile: String, paddle格式的模型文件路径，如 model.pdmodel
+  - paramFile: String, paddle格式的参数文件路径，如 model.pdiparams
+  - labelFile: String, 可选参数，表示label标签文件所在路径，用于可视化，如 ppocr_keys_v1.txt，每一行包含一个label
+  - option: RuntimeOption，可选参数，模型初始化option。如果不传入该参数则会使用默认的运行时选项。
+    与其他模型不同的是，PP-OCRv2 和 PP-OCRv3 包含 DBDetector、Classifier和Recognizer等基础模型，以及PPOCRv2和PPOCRv3等pipeline类型。
+```java
+// 构造函数: constructor w/o label file
+public DBDetector(String modelFile, String paramsFile);
+public DBDetector(String modelFile, String paramsFile, RuntimeOption option);
+public Classifier(String modelFile, String paramsFile);
+public Classifier(String modelFile, String paramsFile, RuntimeOption option);
+public Recognizer(String modelFile, String paramsFile, String labelPath);
+public Recognizer(String modelFile, String paramsFile,  String labelPath, RuntimeOption option);
+public PPOCRv2();  // 空构造函数，之后可以调用init初始化
+// Constructor w/o classifier
+public PPOCRv2(DBDetector detModel, Recognizer recModel);
+public PPOCRv2(DBDetector detModel, Classifier clsModel, Recognizer recModel);
+public PPOCRv3();  // 空构造函数，之后可以调用init初始化
+// Constructor w/o classifier
+public PPOCRv3(DBDetector detModel, Recognizer recModel);
+public PPOCRv3(DBDetector detModel, Classifier clsModel, Recognizer recModel);
+```  
+- 模型预测 API：模型预测API包含直接预测的API以及带可视化功能的API。直接预测是指，不保存图片以及不渲染结果到Bitmap上，仅预测推理结果。预测并且可视化是指，预测结果以及可视化，并将可视化后的图片保存到指定的途径，以及将可视化结果渲染在Bitmap(目前支持ARGB8888格式的Bitmap), 后续可将该Bitmap在camera中进行显示。
+```java
+// 直接预测：不保存图片以及不渲染结果到Bitmap上
+public OCRResult predict(Bitmap ARGB8888Bitmap)；
+// 预测并且可视化：预测结果以及可视化，并将可视化后的图片保存到指定的途径，以及将可视化结果渲染在Bitmap上
+public OCRResult predict(Bitmap ARGB8888Bitmap, String savedImagePath);
+public OCRResult predict(Bitmap ARGB8888Bitmap, boolean rendering); // 只渲染 不保存图片
+```
+- 模型资源释放 API：调用 release() API 可以释放模型资源，返回true表示释放成功，false表示失败；调用 initialized() 可以判断模型是否初始化成功，true表示初始化成功，false表示失败。
+```java
+public boolean release(); // 释放native资源  
+public boolean initialized(); // 检查是否初始化成功
+```
+
+## 替换 FastDeploy SDK和模型
+替换FastDeploy预测库和模型的步骤非常简单。预测库所在的位置为 `app/libs/fastdeploy-android-sdk-xxx.aar`，其中 `xxx` 表示当前您使用的预测库版本号。模型所在的位置为，`app/src/main/assets/models`。
+- 替换FastDeploy Android SDK: 下载或编译最新的FastDeploy Android SDK，解压缩后放在 `app/libs` 目录下；详细配置文档可参考:
+  - [在 Android 中使用 FastDeploy Java SDK](../../../../../java/android/)
+
+- 替换OCR模型的步骤：
+  - 将您的OCR模型放在 `app/src/main/assets/models` 目录下；
+  - 修改 `app/src/main/res/values/strings.xml` 中模型路径的默认值，如：
+```xml
+<!-- 将这个路径修改成您的模型 -->
+<string name="OCR_MODEL_DIR_DEFAULT">models</string>  
+<string name="OCR_LABEL_PATH_DEFAULT">labels/ppocr_keys_v1.txt</string>
+```  
+
+## 更多参考文档
+如果您想知道更多的FastDeploy Java API文档以及如何通过JNI来接入FastDeploy C++ API感兴趣，可以参考以下内容:
