Question

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，但我真的想删除该错误。

详细堆栈跟踪：

Answer 1

我通过更新crashlytics库版本解决了很多错误日志和上面的例外。

Answer 2

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

为了方便起见，我将修复代码留在这里：

dependencies {

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

}

结构库中格式错误的异常
