我尝试将Crashlytics添加到我的应用中，该应用已通过StrictMode启用了detectAll()。结果为Untagged socket detected; use TrafficStats.setThreadSocketTag() to track all network usage。

W/System.err: StrictMode VmPolicy violation with POLICY_DEATH; shutting down.
我试图创建一个新项目，它与测试项目中MainActivity中的代码相同：
@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），但是我不知道这是否有意义。
我将添加一个变通方法作为答案（基本上不使用detectAll()），但是我想知道是否有合适的解决方案，也许有一种将标记添加到套接字的方法？
答案 0 :(得分：1)
一种解决方法是不使用detectAll()，我复制了detectAll()的代码（来自Crashlytics）并进行了修改；但是，由于有些类无法访问，因此我不得不删除部分代码。
我不是这种解决方法的忠实拥护者，但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penaltyDeath()中删除VmPolicy-这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());
}
答案 1 :(得分：0)
Api 28引入了：
public StrictMode.VmPolicy.Builder penaltyListener (Executor executor,
StrictMode.OnVmViolationListener listener)
因此，至少您可以侦听特定的违规行为（例如UntaggedSocketViolation）并选择忽略它们。当然，如果Crashlytics适当地标记其套接字会更好。
