Java apache ant上的crashlytics生成错误导致应用程序崩溃

我们已经为android项目配置了Crashlytics。我们已经为开发人员机器设置了eclipse插件，并且我们正在尝试将ant模块用于构建机器。 我们按照网站上的说明进行了操作，但不幸的是，当我们在设备上运行已签名的APK版本时，应用程序崩溃，logcat显示

我们还缺少哪些额外的步骤

完成的步骤：

1.) Eclipse plugin added, manifest has crashlytics API key
2.) Crashlytics ant folder copied to build machine and imported by custom_rules.xml

我们遵循了此处提到的说明：

但无济于事

请注意，使用eclipse构建的应用程序不会出现任何错误。Mike来自Crashlytics。为添加导入文件将crashlytics_build.xml添加到build.xml中的类似行上方：

<import file="${sdk.dir}/tools/ant/build.xml" /

我在使用gradle时也犯了同样的错误，有没有解决办法？android studio有什么特点？从windows机器编译时，我的应用程序运行良好，但在mac上编译时，它会崩溃，但出现相同的异常。使用gradle时，我也会出现相同的错误。有解决方法吗？android studio有什么好处？从windows机器编译时，我的应用程序运行良好，但在mac上编译时，它崩溃了，只有一个例外。
