织物库中的格式错误的异常

【中文标题】织物库中的格式错误的异常

【英文标题】：Malformed exception in fabric library

【问题描述】：

最近我在日志中看到一个异常，即 Fabric（Beta）尝试检查更新，这是错误：

E/Beta: Error while checking for updates from null
io.fabric.sdk.android.services.network.HttpRequest$HttpRequestException: java.net.MalformedURLException: Protocol not found: null?instance=

我不知道为什么 Fabric 会尝试使用空 URL 检查更新，但我真的很想消除该错误。

详细的堆栈跟踪：

【参考方案1】：

我通过更新 crashlytics 库版本解决了很多错误日志和上面的异常。

【讨论】：

这也对我有用，我仍在寻找 Fabric 中关于为什么会发生这种情况的任何信息，或者他们是否甚至知道发生这种情况但还没有。如果您找到任何东西，请发布链接。

【参考方案2】：

我还解决了在 /app/build.gradle 文件中更新 Crashlytics 版本的问题。

为了方便，我把修复代码留在这里：

dependencies 

    compile('com.crashlytics.sdk.android:crashlytics:2.9.4@aar') 
        transitive = true;
