The import org.apache.http.client cannot be resolved error when I update sdk to M

For eclipse -- Find library in your sdk and add it manuallyplatforms/android-23/optional/org.apache.http.legacy.jar

For android studio add this line in build.gradle

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

android androidhttpclient

for android studio add one line in build.gradle file of app like:

android {       compileSdkVersion 23       ....       defaultConfig {       ..       ..       } useLibrary 'org.apache.http.legacy'}

android androidhttpclient
