java - Android - 10000 毫秒后无法连接到 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。

它不工作。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.
    io.fabric.sdk.android.services.network.HttpRequest$HttpRequestException: java.net.SocketTimeoutException: failed to connect to settings.crashlytics.com/54.83.49.38 (port 443) after 10000ms

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

基本上连接不工作...

原因可能是:

1. 常见的连接问题

2. 其他阻止软件(Adblockers)/(首先检查，常见问题)

3. 代理或一些特定的端口设置

4. 可能还有很多其他的...

很难说这种情况下可能是什么原因。我会尝试不同的条件。
