Question

我试图将我现有的游戏（用libgdx编写）从Eclipse迁移到Android Studio。迁移我的桌面项目后正常工作，但我的Android项目有问题。在Android中我使用Admob广告。

我收到以下错误消息：

如您所见，Android Support Repository已安装

我的项目结构：

我试图将android支持更改为其他版本，但我得到同样的错误。

任何帮助将不胜感激。

Answer 1

我认为您导入项目的问题是由此引起的

buildToolsVersion "19.1.0"
compileSdkVersion 19

您尝试使用比Android支持库更旧的buildTools：

    compile 'com.android.support:support-v4:21.0.0'
    compile 'com.android.support:appcompat-v7:21.0.0'

您需要做的就是将上面的值更改为21。

请按以下步骤操作：

Prerequirements

确保您已下载最新的extras以及   通过SDK-Manager Android 5.0 SDK。



Android Studio

打开应用模块的build.gradle文件，然后更改您的   compileSdkVersion到21.基本上没有必要改变   targetSdkVersion SDK-Version到21，但是建议你这样做   应始终target the latest android Build-Version。在里面   结束你gradle文件将如下所示：
android {
    compileSdkVersion 21
    // ...

    defaultConfig {
        // ...
        targetSdkVersion 21
    }
}
请务必事后同步您的项目。

还要更改buildToolsVersion：

buildToolsVersion "19.1.0"

到

buildToolsVersion "21.1.2"

应该有效

如果你想让你的项目比上面更新，这里是我前一段时间创建的build.gradle我的Android项目：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.piotr.myapplication"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'

    compile 'com.google.android.gms:play-services:8.4.0'
}

编辑：仍然缺少某些东西。请尝试以下步骤

将您的依赖项更新为上述最新版本。
添加此行

`在

之前

`android {
         buildToolsVersion "19.1.0"`

并更改

repositories {
    mavenCentral()
    ...

与

 repositories {
          jcenter()
          mavenCentral()
          ...

希望有所帮助

Answer 2

最后我找到了解决方案

我使用libGDX project setup创建了一个空白的新libGDX项目，其包含与我之前的设置相同的包，并且我将所有类从旧项目复制到这个新项目。完成所有操作后，我得到了我的代码的工作版本。

我没有注意到buld.gradle作为评论和@piotrek1543答案提交的任何差异。

我不知道究竟是什么问题，但我的项目现在有效。

我希望这将有助于将来的任何人！

Answer 3

非常难过，每次我在gradle设置中包含nexus存储库管理器时都会出现此错误

repositories{
maven{  url "http://localhost:8081/nexus/content/groups/public/" }
}

我被迫删除删除本地nexus存储库，并进行编译。我觉得越来越多，谷歌对发展中国家的开发商的需求不敏感，因为互联网真的很贵而且速度很慢。我被迫离开了

repositories{
jcenter()
}
