我刚把android studio从0.6.1更新到0.8.1
我的代码没有改变，但是新的更新破坏了一切。似乎整个android sdk没有正确加载。一个给定的类最终看起来是这样的：
这个项目仍然使用旧的Ant编译系统，但是我有另一个使用Gradle的项目，同样的问题正在发生。当我回到我原来的0.6.1版本时，它工作得很好。
我检查了项目结构，以确保项目sdk指向正确的位置。
Gradle控制台在将项目与Gradle同步时不返回错误：
Executing tasks: [:app:generateDebugSources, :wearable:generateDebugSources, :facebook:generateDebugSources]
Configuration on demand is an incubating feature.
Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0

BUILD SUCCESSFUL
Total time: 4.053 secs
gradle类路径是
com.android.tools.build:gradle:0.12.+根据请求从项目的应用程序文件夹中获取build.gradle文件：
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion '20'
defaultConfig {
applicationId 'com.bandsintown'
minSdkVersion 10
targetSdkVersion 20
versionCode 113
versionName '4.6.5'
}
buildTypes {
release {
debuggable false
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
lintOptions {

}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:20.+'
compile 'com.nineoldandroids:library:2.4.+'
compile 'com.viewpagerindicator:library:2.4.1@aar'
compile 'com.google.android.gms:play-services:5.+'
compile project(':facebook')
}
事实上，我注意到第一行在复制时是错误的。它过去是
apply plugin: 'android'的，但现在已经改变了，新版本的gradle变成了您在com.android.application中看到的那样。然而，改变这条线仍然给我同样的问题。有什么想法吗？
最佳答案
从0.6.1升级到0.8.0时，我遇到了类似的问题
不幸的是，我不能百分之百确定我是如何解决的，但我认为以下几点救了我：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ibma.ibmaapp"
android:versionCode="2"
android:versionName="1.0">
<uses-sdk
android:minSdkVersion="19"
android:targetSdkVersion="19"
android:maxSdkVersion="19" />
...
</manifest>
在androidmanifest.xml中添加sdkversion（见上文）
单击菜单“文件”>“无效缓存/重新启动…”
如果尚未修复，请打开sdk管理器并卸载“android l”和“android w4.4”包（如果已安装）
再检查一遍，也许重复步骤2
