使用 LogCat 时，日志会显示 3 次。谁能解释为什么会这样？日志样本：

这发生在我身上几次。尝试重置 DDMS（它是 Eclipse 中的一个隐藏选项，查找“屏幕截图”按钮旁边的向下箭头）。

如果您使用 Timber 等库进行日志记录，请检查您的 CustomApplication 类。您可能会多次初始化库，例如：

public class CustomApplication extends Application {
  @Override public void onCreate() {
    super.onCreate();

    if (BuildConfig.DEBUG) {
      Timber.plant(new DebugTree());
      Timber.plant(new DebugTree());
    }
  }
}
