Proguard and error

Question

I use this proguard file:

 -dontskipnonpubliclibraryclasses
 -dontskipnonpubliclibraryclassmembers

 !code/simplification/arithmetic,!code/simplification/cas         


        

Answer 1

It looks like the warning comes from the google library, have you tried something like that:

-dontwarn com.google.android.gms.**
-keep class com.google.android.gms.**

I would also try without the dontwarn cause I would assume you want to be warned if there is something to be warned about!

Answer 2

In Eclipse find org.apache.http.legacy.jar in ..sdk/platforms/android-23/optional.

Import it like external jar, check order/export and in proguard type:

-keep class org.apache.http.** { *; }
-keepclassmembers class org.apache.http.** {*;}
-dontwarn org.apache.**

-keep class android.net.http.** { *; }
-keepclassmembers class android.net.http.** {*;}
-dontwarn android.net.**

Answer 3

Add following lines in your proguard file.

-keep class org.apache.http.** { *; }
-keep class org.apache.** { *; }
-dontwarn org.apache.**
-dontwarn org.apache.http.**
-dontwarn org.apache.commons.**

I had the same problem.

I found the answer here and it worked for me: How to add Apache HTTP API (legacy) as compile-time dependency to build.grade?

In your top level build.gradle file add:

buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}
...

In your app-specific build.gradle file add:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"
    useLibrary 'org.apache.http.legacy'
    ...
}

Hope it works for you! it works now with ProGuard on. I had the exact same problem as you.
