Android - 10000ms后无法连接到settings.crashlytics.com/54.83.49.38(端口443)

Question

我在我的Android应用程序中使用fabric.io SDK.

它不起作用.在Android Studio Logcat中出现此错误消息:

E/Fabric? Unknown error while loading Crashlytics settings. Crashes will be cached until settings can be retrieved.

08-28 16:42:29.665  22669-22710/com.my.app W/Fabric? Received null settings, skipping initialization!
08-28 16:42:29.665  22669-22705/com.my.app E/Answers? Failed to retrieve settings

这是我的应用程序类:

...
    @Override
    public void onCreate() {
        super.onCreate();
        //Initiate SDKs
        Fabric.with(this, new Crashlytics());   //Crashlytics
        FacebookSdk.sdkInitialize(this);        //Facebook
        registerParse();                        //Parse
...

Answer 1

基本上连接不起作用......

Resons可能是:

1. 通常的连接问题

2. 阻止其他软件(Adblockers)/(检查第一个常见问题)

3. 代理或某些特定的端口设置

4. 可能还有很多其他......

在这种情况下,很难说出原因可能是什么.我会尝试不同的条件.
