Android手机"DCD ON“错误，经常在Logcat中运行

Question

我正在试着运行和测试我的应用程序，但是在我的LogCat (除了我的应用程序通常的堆栈跟踪)中，我得到了所有这些奇怪的额外的红色错误，并且不知道它是来自什么。这是令人沮丧的，因为它不断增加更多的行，当我只是试图找到我的应用程序错误，所以很难滚动找到我的应用程序错误。即使我没有按手机上的任何东西，它也会不断添加这些奇怪的DCD ON线等等.知道如何阻止他们成为我的LogCat吗？我正在使用三星Galaxy 5。谢谢。

Answer 1

我讨厌工具不做你需要他们做的事情。像你这样的问题，我挣扎了很长时间。最初，我尝试使用命令行，并将grep链接在一起，但在您失去所有输出之前，似乎只能链接几个。我在那上面浪费了很多时间。

DCD ON是由/system/bin/smdexe公司生产的。您可以尝试筛选出smdexe正在运行的PID。

如果你在Mac上，我认为你最好的选择是使用LogRabbit (我是这个工具的创建者，所以我当然有偏见)。

启动记录器，然后右键单击应用程序名称，只查看LogRabbit中的消息。选择“添加过滤器.”。保存筛选器并从列表中进行选择。现在，您将只看到您的应用程序数据。你可以做得更多，但这是一个很好的起点。

以下是您可以做的一些教程：https://www.youtube.com/watch?v=HeildKynnuc&list=PLZVr2R6DumNZUoMZRndqM7cL63gp2NTYE

希望这能帮到你。

顺便说一句，这是一个动画GIF，我认为它解释了在Android和Eclipse：http://imgur.com/q8q0pJC中，logcat的滚动锁是什么样子的

Answer 2

要完成任务(请参阅“只从应用程序获取所有日志”)，您必须通过标记或包名过滤logcat输出：

tag:MyTag

或

app:com.myapplicationpackage

编辑：如果您想获得所有的logcat错误，并且第一个过滤解决方案听起来不适合您，您仍然可以通过在终端中打印logcat，并在错误行中排除"DCD“，来解决这个问题：

adb logcat *:E | grep -v "DCD ON"

或

adb logcat | grep -e "E/" | grep -v "DCD ON"

更新(关于"DCD ON“)：由于DCD (数据载体检测)的在线状态，消息E/SMD﹕ DCD ON似乎是进程间通信的一部分。要获得更精确的信息，您可以与高通开发商论坛联系。

Answer 3

On Mac

退出Android Studio并再次运行它。解决了我的问题。
