Getting Started

1. Configure Matrix version in gradle.properties.

  MATRIX_VERSION=0.4.7

2. Add matrix-gradle-plugin in your build.gradle:

  repositories {
    maven {
      url "https://dl.bintray.com/matrix/maven/"
    }
  }

  dependencies {
      classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
  }
 

3. Add dependencies to your app/build.gradle.

  dependencies {
    implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
  }
  
  apply plugin: 'com.tencent.matrix-plugin'
  matrix {
    trace {
        enable = true	//if you don't want to use trace canary, set false
        baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
        blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
    }
  }

4. Implement PluginListener to receive data processed by Matrix.

  public class TestPluginListener extends DefaultPluginListener {
    public static final String TAG = "Matrix.TestPluginListener";
    public TestPluginListener(Context context) {
        super(context);
        
    }

    @Override
    public void onReportIssue(Issue issue) {
        super.onReportIssue(issue);
        MatrixLog.e(TAG, issue.toString());
        
        //add your code to process data
    }
}

5. Implement DynamicConfig to change parametes of Matrix.

  public class DynamicConfigImplDemo implements IDynamicConfig {
    public DynamicConfigImplDemo() {}

    public boolean isFPSEnable() { return true;}
    public boolean isTraceEnable() { return true; }
    public boolean isMatrixEnable() { return true; }
    public boolean isDumpHprof() {  return false;}

    @Override
    public String get(String key, String defStr) {
        //hook to change default values
    }

    @Override
    public int get(String key, int defInt) {
      //hook to change default values
    }

    @Override
    public long get(String key, long defLong) {
        //hook to change default values
    }

    @Override
    public boolean get(String key, boolean defBool) {
        //hook to change default values
    }

    @Override
    public float get(String key, float defFloat) {
        //hook to change default values
    }
}

6. Init Matrix in the onCreate of your application.

  Matrix.Builder builder = new Matrix.Builder(application); // build matrix
  builder.patchListener(new TestPluginListener(this)); // add general pluginListener
  DynamicConfigImplDemo dynamicConfig = new DynamicConfigImplDemo(); // dynamic config
  
  // init plugin 
  IOCanaryPlugin ioCanaryPlugin = new IOCanaryPlugin(new IOConfig.Builder()
                    .dynamicConfig(dynamicConfig)
                    .build());
  //add to matrix               
  builder.plugin(ioCanaryPlugin);
  
  //init matrix
  Matrix.init(builder.build());

  // start plugin 
  ioCanaryPlugin.start();

For more Matrix configurations, look at the sample.

Matrix

Matrix 是一款微信研发并日常使用的 APM（Application Performance Manage），当前主要运行在 Android 平台上。 Matrix 的目标是建立统一的应用性能接入框架，通过各种性能监控方案，对性能监控项的异常数据进行采集和分析，输出相应的问题分析、定位与优化建议，从而帮助开发者开发出更高质量的应用。

Matrix 当前监控范围包括：应用安装包大小，帧率变化，启动耗时，卡顿，慢方法，SQLite 操作优化，文件读写，内存泄漏等等。

• APK Checker: 针对 APK 安装包的分析检测工具，根据一系列设定好的规则，检测 APK 是否存在特定的问题，并输出较为详细的检测结果报告，用于分析排查问题以及版本追踪
• Resource Canary: 基于 WeakReference 的特性和 Square Haha 库开发的 Activity 泄漏和 Bitmap 重复创建检测工具
• Trace Canary: 监控界面流畅性、启动耗时、页面切换耗时、慢函数及卡顿等问题
• SQLite Lint: 按官方最佳实践自动化检测 SQLite 语句的使用质量
• IO Canary: 检测文件 IO 问题，包括：文件 IO 监控和 Closeable Leak 监控

特性

与常规的 APM 工具相比，Matrix 拥有以下特点：

APK Checker

• 具有更好的可用性：JAR 包方式提供，更方便应用到持续集成系统中，从而追踪和对比每个 APK 版本之间的变化
• 更多的检查分析功能：除具备 APKAnalyzer 的功能外，还支持统计 APK 中包含的 R 类、检查是否有多个动态库静态链接了 STL 、搜索 APK 中包含的无用资源，以及支持自定义检查规则等
• 输出的检查结果更加详实：支持可视化的 HTML 格式，便于分析处理的 JSON ，自定义输出等等

Resource Canary

• 分离了检测和分析部分，便于在不打断自动化测试的前提下持续输出分析后的检测结果
• 对检测部分生成的 Hprof 文件进行了裁剪，移除了大部分无用数据，降低了传输 Hprof 文件的开销
• 增加了重复 Bitmap 对象检测，方便通过减少冗余 Bitmap 数量，降低内存消耗

Trace Canary

• 编译期动态修改字节码, 高性能记录执行耗时与调用堆栈
• 准确的定位到发生卡顿的函数，提供执行堆栈、执行耗时、执行次数等信息，帮助快速解决卡顿问题
• 自动涵盖卡顿、启动耗时、页面切换、慢函数检测等多个流畅性指标

SQLite Lint

• 接入简单，代码无侵入
• 数据量无关，开发、测试阶段即可发现SQLite性能隐患
• 检测算法基于最佳实践，高标准把控SQLite质量*
• 底层是 C++ 实现，支持多平台扩展

IO Canary

• 接入简单，代码无侵入
• 性能、泄漏全面监控，对 IO 质量心中有数
• 兼容到 Android P

使用方法

1. 在你项目根目录下的 gradle.properties 中配置要依赖的 Matrix 版本号，如：

  MATRIX_VERSION=0.4.7

2. 在你项目根目录下的 build.gradle 文件添加 Matrix 依赖，如：

  repositories {
    maven {
      url "https://dl.bintray.com/matrix/maven/"
    }
  }

  dependencies {
      classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
  }

3. 接着，在 app/build.gradle 文件中添加 Matrix 各模块的依赖，如：

  dependencies {
    implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
  }

  apply plugin: 'com.tencent.matrix-plugin'
  matrix {
    trace {
        enable = true	//if you don't want to use trace canary, set false
        baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
        blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
    }
  }

4. 实现 PluginListener，接收 Matrix 处理后的数据, 如：

  public class TestPluginListener extends DefaultPluginListener {
    public static final String TAG = "Matrix.TestPluginListener";
    public TestPluginListener(Context context) {
        super(context);
        
    }

    @Override
    public void onReportIssue(Issue issue) {
        super.onReportIssue(issue);
        MatrixLog.e(TAG, issue.toString());
        
        //add your code to process data
    }
}

5. 实现动态配置接口， 可修改 Matrix 内部参数. 在 sample-android 中 我们有个简单的动态接口实例DynamicConfigImplDemo.java, 其中参数对应的 key 位于文件 MatrixEnum中， 摘抄部分示例如下：

  public class DynamicConfigImplDemo implements IDynamicConfig {
    public DynamicConfigImplDemo() {}

    public boolean isFPSEnable() { return true;}
    public boolean isTraceEnable() { return true; }
    public boolean isMatrixEnable() { return true; }
    public boolean isDumpHprof() {  return false;}

    @Override
    public String get(String key, String defStr) {
        //hook to change default values
    }

    @Override
    public int get(String key, int defInt) {
         //hook to change default values
    }

    @Override
    public long get(String key, long defLong) {
        //hook to change default values
    }

    @Override
    public boolean get(String key, boolean defBool) {
        //hook to change default values
    }

    @Override
    public float get(String key, float defFloat) {
        //hook to change default values
    }
}

6. 选择程序启动的位置对 Matrix 进行初始化，如在 Application 的继承类中， Init 核心逻辑如下：

  Matrix.Builder builder = new Matrix.Builder(application); // build matrix
  builder.patchListener(new TestPluginListener(this)); // add general pluginListener
  DynamicConfigImplDemo dynamicConfig = new DynamicConfigImplDemo(); // dynamic config
  
  // init plugin 
  IOCanaryPlugin ioCanaryPlugin = new IOCanaryPlugin(new IOConfig.Builder()
                    .dynamicConfig(dynamicConfig)
                    .build());
  //add to matrix               
  builder.plugin(ioCanaryPlugin);
  
  //init matrix
  Matrix.init(builder.build());

  // start plugin 
  ioCanaryPlugin.start();

至此，Matrix就已成功集成到你的项目中，并且开始收集和分析性能相关异常数据，如仍有疑问，请查看 示例.
