1.先Enable Android SUPPORT,可以在file->setting->plugin设置
2.尝试删除C:\Users\Administrator下面的.AndroidStudio/config
, .AndroidStudio/system
and .AndroidStudio/plugins
,一定要先备份。重启试试。
3. 按如下设置: File >> Invalidate caches/restart >> Invalidate and Restart
重启AS,有警告则点击:Enable Android Support
4. 尝试删除项目目录下的 .idea/workspace.xml
,记得先备份。重启AS再Enable Android Support
5.尝试更新: Android Studio ,从菜单操作:Help>CheckForUpdates>Update.
6. 尝试增加如下参数大小: -Xmx
and -XX:MaxPermSize
values in the studio.vmoptions
file
7.尝试如下步骤:
- Close Android Studio
- Remove .idea/workspace.xml
- Restart android studio (your project with the issue is opened automatically)
- A new .idea/workspace.xml is created
- Sync project with gradle files
- Open File -> Settings - > Plugins -> Enable
- "Android Support" Plugin.
- Android NDK support (I had to disable and re-enable it)
- Restart Android Studio
8.尝试替换 build.gradle 文件,如下:
buildscript {
...
repositories {
mavenLocal()
maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
maven { url "https://jitpack.io" }
mavenCentral() // jcenter() works as well because it pulls from Maven Central
maven {
url 'https://maven.google.com/'
name 'Google'
}
jcenter()
}
...
}
allprojects {
repositories {
mavenLocal()
maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
maven { url "https://jitpack.io" }
mavenCentral() // jcenter() works as well because it pulls from Maven Central
maven {
url 'https://maven.google.com/'
name 'Google'
}
jcenter()
}
}
