strictmode java.lang.throwablable:未标记的插座

Question

启用了strictmode，我刚开始获得此例外：

java.lang.throwable：检测到未标记的插座；使用clabilstats.setthreadsockettag（）跟踪所有网络使用

Answer 1

有几种处理此异常的方法。首先，您必须检查堆栈跟踪，并确保是您的代码报告违规行为。例如，请查看以下迹线。

D/StrictMode: StrictMode policy violation: android.os.strictmode.UntaggedSocketViolation: Untagged socket detected; use TrafficStats.setThreadSocketTag() to track all network usage
    at android.os.StrictMode.onUntaggedSocket(StrictMode.java:2124)
    at com.android.server.NetworkManagementSocketTagger.tag(NetworkManagementSocketTagger.java:82)
    at libcore.io.BlockGuardOs.tagSocket(BlockGuardOs.java:52)
    at libcore.io.BlockGuardOs.socket(BlockGuardOs.java:372)
    at libcore.io.ForwardingOs.socket(ForwardingOs.java:217)
    at libcore.io.IoBridge.socket(IoBridge.java:658)

    at java.net.AbstractPlainSocketImpl.create(AbstractPlainSocketImpl.java:128)
    at java.net.ServerSocket.createImpl(ServerSocket.java:306)
    at java.net.ServerSocket.getImpl(ServerSocket.java:259)
    at java.net.ServerSocket.bind(ServerSocket.java:377)

    at java.net.ServerSocket.<init>(ServerSocket.java:128)
    at com.java42.android03.binder.peer.messaging.J42PM_ServerConnection.run(J42PM_ServerConnection.java:52)
    at com.java42.base.components.utility.impl.Utility_Thread$1.run(Utility_Thread.java:137)
    at java.lang.Thread.run(Thread.java:919)
    at com.java42.utility.base.J42Thread.run(J42Thread.java:38)

违规的应用程序呼叫是：

J42PM_ServerConnection.run(J42PM_ServerConnection.java:52)

接下来，看看该代码：

public void run() {
    try (ServerSocket serverSocket = new ServerSocket(port)) {
        this.serverSocket = serverSocket;
        CallerId.identifyBasic("J42PSC0179D: listening Inbound....");
        while (!Thread.currentThread().isInterrupted()) {
        ...

由于这是服务器端循环，并且线程ID不会在服务器过程的寿命上更改，因此您可以使用当前线程ID来解决违规行为。

public void run() {
    TrafficStats.setThreadStatsTag((int) Thread.currentThread().getId()); // <---
    try (ServerSocket serverSocket = new ServerSocket(port)) {
        this.serverSocket = serverSocket;
        CallerId.identifyBasic("J42PSC0179D: listening Inbound....");
        while (!Thread.currentThread().isInterrupted()) {
        ...

让我们看一下另一个痕迹：

D/StrictMode: StrictMode policy violation: android.os.strictmode.UntaggedSocketViolation: Untagged socket detected; use TrafficStats.setThreadSocketTag() to track all network usage
    at android.os.StrictMode.onUntaggedSocket(StrictMode.java:2124)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
    at java.lang.Thread.run(Thread.java:919)

与第一个示例一样，您确定违规的应用程序呼叫：

J42PM_ClientConnection.run(J42PM_ClientConnection.java:54)

接下来，看看该代码：

InetSocketAddress socketAddress = serviceResolver.getSocketAddress();
    connection = new J42PM_ClientConnection(socketAddress, responseHandler);
    executorService.execute(new Runnable() {
        @Override
        public void run() {
        connection.run();
        ...

请注意，此代码使用执行程序服务来运行客户端连接。随着连接的创建和破坏，线程ID将在过程的生命中发生变化。我不确定这是否会偏向流量报告，但我认为最好使用恒定值跟踪使用情况。选择一些唯一的数字。使用文件的行号是一个简单的选择。

    InetSocketAddress socketAddress = serviceResolver.getSocketAddress();
    connection = new J42PM_ClientConnection(socketAddress, responseHandler);
    executorService.execute(new Runnable() {
        @Override
        public void run() {
        TrafficStats.setThreadStatsTag(42); // <--
        connection.run();
        ...

最后一个评论，如果您在堆栈跟踪中没有看到对代码的调用，那么您没有什么可以阻止违规行为。问题在另一个库中，除非您可以联系图书馆所有者，否则只需忽略违法行为。

Answer 2

我的解决方案是调用初始化：

private static final int THREAD_ID = 10000;
TrafficStats.setThreadStatsTag(THREAD_ID);

Answer 3

如果使用OKHTTP客户端，请创建Interceptor并在intercept方法实现中添加到以下行

  TrafficStats.setThreadStatsTag(Thread.currentThread().id.toInt())
