app性能监测 特价

// 示例代码：优化启动流程
App({
  onLaunch: function() {
    // 只执行必要的初始化任务
    this.initEssentialServices();
  },
  initEssentialServices: function() {
    // 初始化核心服务
  }
});

// 示例代码：避免内存泄漏
public class MyActivity extends AppCompatActivity {
  private Handler handler = new Handler();

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // 避免匿名内部类持有外部类的引用
    handler.postDelayed(new Runnable() {
      @Override
      public void run() {
        // 执行任务
      }
    }, 1000);
  }

  @Override
  protected void onDestroy() {
    super.onDestroy();
    handler.removeCallbacksAndMessages(null); // 清除回调防止内存泄漏
  }
}
