各种第一次遇到的android studio报错
- All packages are not available for download! The following packages are not available:
- Package id build-tools;27.0.3
解决方法：File->settings->Appearance & Behavior->System Settings->HTTP Proxy->勾选No proxy
- Unable to resolve dependency for ‘:[email protected]/compileClasspath’: Could not resolve com.android.support:appcompat-v7:27.1.1.
解决方法：
设置里面关代理然后在gradle.properties里注释代码
- Failed to load AppCompat ActionBar with unknown error.
在style.xml文件中找到下面这行代码，前面加上“Base.”
