+# 安卓APP
+
+## 目的
+
+1. 实现页面按钮跳转页面
+2. 点击按钮后，页面显示来自JNI的字符串
+
+## 实验步骤
+
+### 1. 准备开发环境
+
+- Android Studio
+- JDK
+- NDK（创建项目时会自动部署）
+- CMake（创建项目时会自动部署）
+
+### 2. 创建一个原生C++安卓项目
+
+![image-20241217213119132](images/image-20241217213119132.png)
+
+> 部署原生C++安卓项目时，路径中不能有空格
+>
+> 使用了API 28: Android 9.0
+
+### 3. 主页面添加按钮
+
+在`MainActivity.java`中添加一个按钮，点击后跳转到`SecondActivity`
+
+```
+package com.example.jnidemoapp;
+
+import android.content.Intent;
+import android.os.Bundle;
+import android.view.View;
+import android.widget.Button;
+import androidx.appcompat.app.AppCompatActivity;
+
+public class MainActivity extends AppCompatActivity {
+    @Override
+    protected void onCreate(Bundle savedInstanceState) {
+        super.onCreate(savedInstanceState);
+        setContentView(R.layout.activity_main);
+
+        // 页面跳转按钮
+        Button button = findViewById(R.id.button_go_to_second);
+        button.setOnClickListener(new View.OnClickListener() {
+            @Override
+            public void onClick(View v) {
+                Intent intent = new Intent(MainActivity.this, SecondActivity.class);
+                startActivity(intent);
+            }
+        });
+    }
+}
+```
+
+### 4. 创建SecondActivity.java
+
+新建`SecondActivity.java`文件，显示来自JNI的字符串
+
+```
+package com.example.jnidemoapp;
+
+import android.os.Bundle;
+import android.widget.TextView;
+import androidx.appcompat.app.AppCompatActivity;
+
+public class SecondActivity extends AppCompatActivity {
+
+    // 加载本地库
+    static {
+        System.loadLibrary("jnidemoapp");
+    }
+
+    // 声明一个本地方法
+    public native String stringFromJNI();
+
+    @Override
+    protected void onCreate(Bundle savedInstanceState) {
+        super.onCreate(savedInstanceState);
+        setContentView(R.layout.activity_second);
+
+        // 显示 JNI 返回的字符串
+        TextView textView = findViewById(R.id.text_jni_string);
+        textView.setText(stringFromJNI());
+    }
+}
+```
+
+### 5. 调整界面布局
+
+- 在`activity_main.xml`中添加一个按钮：
+  ```
+  <?xml version="1.0" encoding="utf-8"?>
+  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
+      android:layout_width="match_parent"
+      android:layout_height="match_parent">
+  
+      <Button
+          android:id="@+id/button_go_to_second"
+          android:layout_width="wrap_content"
+          android:layout_height="wrap_content"
+          android:text="跳转"
+          android:layout_centerInParent="true"/>
+  </RelativeLayout>
+  ```
+
+- 在 `activity_second.xml` 添加一个 `TextView`：
+  ```
+  <?xml version="1.0" encoding="utf-8"?>
+  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
+      android:layout_width="match_parent"
+      android:layout_height="match_parent">
+  
+      <TextView
+          android:id="@+id/text_jni_string"
+          android:layout_width="wrap_content"
+          android:layout_height="wrap_content"
+          android:text="等待JNI数据..."
+          android:textSize="18sp"
+          android:layout_centerInParent="true"/>
+  </RelativeLayout>
+  ```
+
+### 6. 添加JNI字符串
+
+- 配置`CMakeLists.txt`文件
+
+  ```
+  # For more information about using CMake with Android Studio, read the
+  # documentation: https://d.android.com/studio/projects/add-native-code.html
+  
+  # Sets the minimum version of CMake required to build the native library.
+  
+  cmake_minimum_required(VERSION 3.22.1)
+  
+  # Declares and names the project.
+  
+  project("jnidemoapp")
+  
+  # Creates and names a library, sets it as either STATIC
+  # or SHARED, and provides the relative paths to its source code.
+  # You can define multiple libraries, and CMake builds them for you.
+  # Gradle automatically packages shared libraries with your APK.
+  
+  add_library( # Sets the name of the library.
+          jnidemoapp
+  
+          # Sets the library as a shared library.
+          SHARED
+  
+          # Provides a relative path to your source file(s).
+          native-lib.cpp)
+  
+  # Searches for a specified prebuilt library and stores the path as a
+  # variable. Because CMake includes system libraries in the search path by
+  # default, you only need to specify the name of the public NDK library
+  # you want to add. CMake verifies that the library exists before
+  # completing its build.
+  
+  find_library( # Sets the name of the path variable.
+          log-lib
+  
+          # Specifies the name of the NDK library that
+          # you want CMake to locate.
+          log)
+  
+  # Specifies libraries CMake should link to your target library. You
+  # can link multiple libraries, such as libraries you define in this
+  # build script, prebuilt third-party libraries, or system libraries.
+  
+  target_link_libraries( # Specifies the target library.
+          jnidemoapp
+  
+          # Links the target library to the log library
+          # included in the NDK.
+          ${log-lib})
+  ```
+
+  > 这里的库名称需要和SecondActivity.java中的System.loadLibrary函数中的库名称对应
+
+### 7. 编译运行模拟器，并测试
+
+- 起始页面：
+
+  ![image-20241217214158354](images/image-20241217214158354.png)
+
+- 点击按钮后：
+
+  ![image-20241217214245435](images/image-20241217214245435.png)
