android – Proguard issues with Gradle 3.0.0

Posted by: admin May 14, 2020 Leave a comment

Questions:

I’m trying to create an APK using ProGuard and the new Gradle 3.0.0 version. I’m getting a lot of warnings on classes that I thought I ignored in my ProGuard configuration file. The same configuration works well with Gradle 2.3.3 but seems to break on 3.0.0. The warnings are so many it’s almost not reading the ProGuard configuration at all.

My build.gradle

buildscript {
    repositories {
        mavenCentral()
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.0.0'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'


    }

}


allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://jitpack.io'
        }
        maven {
            url 'https://maven.google.com'
        }

    }
}
android{
 buildTypes {
        release {
            minifyEnabled true

            signingConfig signingConfigs.release
            lintOptions {
                disable 'MissingTranslation'
            }

        }

How to&Answers:

I’ve upgraded to gradle 3.0.1 and most of the warnings are gone. If you’re still on 3.0.0 then use this in your proguard file

-dontwarn android.** 

Not ideal but gets it working.

Answer:

I had the same issue, although my case is kind of unique, here is my solution:

After upgrading to the new 3.0.1 version (com.android.tools.build:gradle:3.0.1), I saw fewer warnings (originally I had >3000 warnings).
The source of my problem was that I used a library which had a dependency on the whole android framework (This one: https://github.com/tony19/logback-android, the issue #73).

I also looked into the dependencies (./gradlew app:dependenices), because I had libraries which depends on the old apache http client, which also causes some warnings. I had to eliminate them as well.

Answer:

It may help you

Enabling ProGuard for local library modules no longer affects the library's code. Instead, you should run ProGuard on the app module that consumes the library.

Answer:

Add below code in android tag

lintOptions { // set to true to turn off analysis progress reporting by lint quiet true // if true, stop the gradle build if errors are found abortOnError false // if true, only report errors ignoreWarnings true }
