sdk 23以上不再支持org.apache.http

sdk 23以上不再支持org.apache.http，你可以将降到sdk22 然后在gradle中添加
compile 'com.Android.support:appcompat-v7:22.2.0'

非要用高版本sdk，则添加

 

android {
    useLibrary 'org.apache.http.legacy'}

 

也可以用OkHttp

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0') If you need sdk 23, add this to your gradle: android { useLibrary 'org.apache.http.legacy'} You also may try to download and include HttpClient jar directly into your project or use OkHttpinstead
