如何修复这些proguard警告

Question

我在我的项目中使用第三方库，从那时起proguard向我发出这些警告，我不能将其与该库联系起来，这是我使用的库:Lollipin

警告我得到

Warning:android.databinding.DataBindingUtil: can't find referenced class android.databinding.DataBinderMapper
Warning:android.databinding.ViewDataBinding: can't find referenced class android.databinding.DataBinderMapper
Warning:there were 43 unresolved references to classes or interfaces.
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.

我试过了吗?

我这样编辑proguard-rules.pro:

-keeppackagenames com.github.orangegangsters.lollipin

还是不去!我也试过清理和重建项目，也没有成功。

build.gradle:

apply plugin: 'com.android.application'
 android {
compileSdkVersion 24
buildToolsVersion '24.0.2'
defaultConfig {
    applicationId "com.example.teach"
    minSdkVersion 15
    targetSdkVersion 24
    versionCode 27
    versionName "5.0"
}
buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:24.2.1'
compile('com.mikepenz:materialdrawer:5.6.0@aar') {
    transitive = true
}
compile ('com.github.orangegangsters:lollipin:2.0.0@aar') {
    transitive = true
}
 compile 'com.google.android.gms:play-services-ads:9.6.0'

}
apply plugin: 'com.google.gms.google-services'

Answer 1

我也有同样的问题，所以我在我的proguard.cfg

中添加了以下更改

-dontwarn android.databinding.**
-keep class android.databinding.** { *; }
-dontwarn okio.**
-dontwarn retrofit2.Platform$Java8
-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

Answer 2

尝试:

-dontwarn com.github.orangegangsters.lollipin

不是

-keeppackagenames com.github.orangegangsters.lollipin

Answer 3

这是因为Lollipin使用了Databinding库。

添加到gradle:

dataBinding {
        enabled = true
}
