【中文标题】Android Studio 与 MobileFirst 的集成【英文标题】：Android Studio integration with MobileFirst 【发布时间】：2015-02-20 15:21:55 【问题描述】：

我在运行与 android Studio 集成的 IBM MobileFirst Studio (Eclipse Kepler) 的本机 android 示例 (Hello World) 时遇到了几个问题。

我遵循了文档中的所有步骤，包括所有先决条件here。当我通过上下文菜单运行应用程序时：右键单击应用程序 Run As > Android Studio Project。 MobileFirst 启动 Android Studio，但应用程序在 AndroidStudio 配置中仍然存在以下错误和警告：

    警告：AndroidStudio 要求我迁移到 Gradle。我忽略了这次迁移，因为我发现 Gradle 的编译和部署延迟相当大。 我选择我的项目并按F4，在Project > Project SDK选项中，SDK无效，我选择一个有效。 在Modules > Modules SDK选项中，SDK无效，我选择了一个喜欢的，同上。 在“库”选项中，找不到 3 个库，因此我删除了引用。 在 SDK 选项中，我只选择 API 10。

此时，应用程序编译并正确部署了模拟器。运行时，IBM 启动画面出现并立即关闭，无需进入应用程序。

logcat 上出现以下内容：

另一个问题是，当我返回从 MobileFirst 启动应用程序时，AndroidStudio 会打开并要求我从外部重新加载修改过的文件（来自 MobileFirst），显然没有同步并且对设置的更改消失了。

有人知道如何解决这些问题吗？

我应该澄清一下，要执行 AndroidStudio，我必须安装 Fix Pack MobileFirst。

对不起我的英语。

感谢您的意见和帮助。

【问题讨论】：

您使用的是来自developer.ibm.com/mobilefirstplatform/documentation/… 的样本之一吗？另外，这是完整的 logcat 输出吗？ 没有两个问题。 我用完整的日志更新了问题 我在 IBM MobileFirst Platform 中从零开始创建了 helloworld 项目 您可以在步骤 2、3 和 4 上花费时间吗？那里什么是无效的，你把它改成了什么？缺少什么？ 【参考方案1】：

Android 的 Worklight 项目目前不支持 Gradle。

对于其余的问题，我通过以下方式解决了问题：

    指定 SDK

    在 app-name.iml 中，从以下行中删除范围：

    <orderEntry type="library" name="libs" level="project" />

最近在 Android Studio 中似乎发生了一些变化，因为项目过去使用它开箱即用（Gradle 除外，目前不支持）。

试试上面的。

【讨论】：

如果我删除该行，应用程序会抛出编译错误：\GCMIntentService.java 错误:(3, 68) java: com.worklight.androidgap.push 包不存在 HelloWorldAgain2.java 错误:(8 , 26) java: 包 org.apache.cordova 不存在 错误:(10, 36) java: 包 com.worklight.androidgap.api 不存在 错误:(11, 36) java: 包 com.worklight.androidgap. api 不存在 Error:(12, 36) java: package com.worklight.androidgap.api 不存在 Error:(14, 39) java: cannot find symbol symbol: class CordovaActivity ...... 我的意思是，用我的替换那行。这只是删除“范围”属性。 那行和我的一样，没有范围属性 嗯，很奇怪。在指出 libs 错误的设置屏幕中，您有一个包含 4 个选项的下拉列表，选择一个后，您可以返回该文件，然后删除范围属性（至少我在那里看到），然后编译工作并显示应用程序。
