i tried lots of jar file http apache library not getting solution. if 1 have suggestion tell me.

error focus line 37 indicate "request" in try catch.

edit again:

after second thought, android's library contains httpclient (pre android 6.0), including yourself, creating conflict. try remove jar , try.

remove line

compile files('libs/httpclient-4.3-beta1.jar')

you may need remove well

compile files('libs/org.apache.commons.logging-1.1.1.jar')
