edit

this how enabling pro-guard in app build.gralde file, using 'proguard-android-optimize.txt

 buildtypes {         release {             minifyenabled true             shrinkresources true             proguardfiles getdefaultproguardfile('proguard-android-optimize.txt'), 'proguard-rules.pro'         }     } 

add this:

-keep class cz.msebera.android.httpclient.** { *; } -dontwarn cz.msebera.android.httpclient.** 

update: try this:

-keep class com.loopj.android.** { *; } -keep interface com.loopj.android.** { *; } -keep class cz.msebera.android.** { *; } -keep interface cz.msebera.android.** { *; } -dontwarn cz.msebera.android.** -dontwarn com.loopj.android.**
