+### Android SDK Demo
+
+We have provided a demo project from the Android SDK source: [hyperlpr3-android-sdk](https://github.com/HyperInspire/hyperlpr3-android-sdk.git)，You can compile the shared library and use the project as needed.
+
+### Quick to use in Android
+
+If you need to quickly integrate our sdk in your own Android project, then you can add the following dependency to your project's build.gradle:
+
+- Step 1. Add the JitPack repository to your build file.Add it in your root build.gradle at the end of repositories:
+
+```java
+allprojects {
+    repositories {
+        ...
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+
+- Step 2. Add the dependency
+```
+dependencies {
+    implementation 'com.github.HyperInspire:hyperlpr3-android-sdk:1.0.2'
+}
+```
+
+- Step 3. Use hyperlpr in your application
+
+```
+// Initialization, which can be performed only once, is usually performed at program initialization
+HyperLPR3.getInstance().init(this, new HyperLPRParameter());
+
+…
+
+// exec recognition
+Plate[] plates =  HyperLPR3.getInstance().plateRecognition(bitmap, HyperLPR3.CAMERA_ROTATION_0, HyperLPR3.STREAM_BGRA);
+```

+
+我们提供了一个Android-SDK相关的Demo工程：[hyperlpr3-android-sdk](https://github.com/HyperInspire/hyperlpr3-android-sdk.git)，您可以根据需求去编译动态库使用该项目。
+
+### 在Android中快速集成HyperLPR
+
+如果你需要快速将我们的sdk集成到你自己的Android项目中，那么你可以将以下依赖添加到项目的build.gradle中:
+
+- 步骤 1. 将JitPack仓库添加到构建文件中。将其添加到根构建中。在仓库末尾添加Gradle:
+
+```
+allprojects {
+	repositories {
+		...
+		maven { url 'https://jitpack.io' }
+	}
+}
+```
+
+- 步骤 2. 添加以下依赖
+```
+dependencies {
+	  implementation 'com.github.HyperInspire:hyperlpr3-android-sdk:1.0.2'
+}
+```
+
+- 步骤 3. 在应用程序中使用hyperlpr
+
+```java
+// 初始化通常在程序初始化时执行，只需执行一次
+HyperLPR3.getInstance().init(this, new HyperLPRParameter());
+
+…
+
+// 识别一张图像
+Plate[] plates =  HyperLPR3.getInstance().plateRecognition(bitmap, HyperLPR3.CAMERA_ROTATION_0, HyperLPR3.STREAM_BGRA);
+```
