启用 StrictMode（检测全部）的 Crashlytics 给出“检测到未标记的套接字”

Question

我尝试将Crashlytics 添加到我的应用程序中，该应用程序已经启用了StrictMode 和detectAll()。结果是Untagged socket detected; use TrafficStats.setThreadSocketTag() to track all network usage。

全栈：

W/System.err: StrictMode VmPolicy violation with POLICY_DEATH; shutting down.

我尝试新建一个项目，还是一样，测试项目中MainActivity中的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    setCrashlytics();
    setStrictMode();
}

private void setCrashlytics() {
    Fabric.with(this, new Crashlytics());
}

private void setStrictMode() {
    if (BuildConfig.DEBUG) {
        StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                .detectAll()
                .penaltyLog()
                .build());
        StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                .detectAll()
                .penaltyLog()
                .penaltyDeath()
                .build());
    }
}

我确实看到了 Okhttp has this issue（以及其他库），但我不知道这是否相关。
我将添加一个解决方法作为答案（基本上不使用detectAll()），但我想知道是否有适当的解决方案，也许有办法将标签添加到套接字？

Answer 1

解决方法是不使用detectAll()，我复制了detectAll() 的代码（来自Crashlytics）并对其进行了修改；但是我不得不删除部分代码，因为有些类无法访问。
我不是这种解决方法的忠实拥护者，但我不确定是否有更好的解决方案。

private void setStrictMode() {
    if (BuildConfig.DEBUG) {
        StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                .detectAll()   // detectDiskReads, detectDiskWrites, detectNetwork
                .penaltyLog()
                .build());

        StrictMode.setVmPolicy(getStrictModeBuilder().build());
    }
}

private StrictMode.VmPolicy.Builder getStrictModeBuilder() {
    StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();

    builder.detectLeakedSqlLiteObjects();

    final int sdkInt = Build.VERSION.SDK_INT;
    if (sdkInt >= Build.VERSION_CODES.HONEYCOMB) {
        builder.detectActivityLeaks();
        builder.detectLeakedClosableObjects();
    }

    if (sdkInt >= Build.VERSION_CODES.JELLY_BEAN) {
        builder.detectLeakedRegistrationObjects();
    }

    if (sdkInt >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
        builder.detectFileUriExposure();
    }

    if (sdkInt >= Build.VERSION_CODES.O) {
        builder.detectContentUriWithoutPermission();
    }

    builder.penaltyLog().penaltyDeath();
    return builder;
}

选项二 - 从VmPolicy 中删除penaltyDeath() - 这就是我目前正在做的事情：

private void setStrictMode() {
if (BuildConfig.DEBUG) {
    StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
            .detectAll()   // detectDiskReads, detectDiskWrites, detectNetwork
            .penaltyLog()
            .build());

    StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                .detectAll()
                .penaltyLog()
                .build());
}

Answer 2

Api 28 已经引入：

public StrictMode.VmPolicy.Builder penaltyListener (Executor executor,
                StrictMode.OnVmViolationListener listener)

因此，至少您可以监听特定的违规行为（例如 UntaggedSocketViolation）并选择忽略它们。当然，如果 Crashlytics 能够适当地标记他们的套接字会更好。
