Error:(50, 9) error: cannot access AsyncHttpClient
bad class file: /Users/user/AndroidStudioProjects/yan.com/Yin/app/libs/android-async-http-1.4.8.jar(com/loopj/android/http/AsyncHttpClient.class)
unable to access file: null
Please remove or make sure it appears in the correct subdirectory of the classpath.
在应用程序下的build.gradle文件中添加依赖项:
dependencies {
compile 'com.loopj.android:android-async-http:1.4.9'
}

如果不起作用,请尝试执行以下命令:
gradlew installarchives
- 它也应该在不下载jar文件的情况下工作
- 另一个注意事项是,我使用的是1.4.5版
