Question

我正在尝试生成签名版本，但它显示以下错误：

Warning:there were 87 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning:there were 2 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.

我尝试了rebuild / clean build选项，但我每次都会遇到同样的错误。

我的项目有以下依赖项：

compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:support-v4:23.1.1'
    compile 'com.android.support:preference-v7:23.1.1'
    compile 'com.android.support:preference-v14:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'com.android.support:palette-v7:23.1.1'
    compile 'com.cocosw:bottomsheet:1.+@aar'
    compile 'com.github.paolorotolo:appintro:3.2.+'
    compile 'com.pnikosis:materialish-progress:1.7'
    compile 'com.google.android.gms:play-services-ads:8.4.0'
    compile('com.crashlytics.sdk.android:crashlytics:2.5.5@aar') {
        transitive = true;
    }

请建议如何解决上述问题。感谢。

Answer 1

看起来ProGuard可能正在剥离您的构建所依赖的类。尝试禁用ProGuard进行发布构建（minifyEnabled false）并查看是否有效。如果这样做，那么您需要配置ProGuard规则，以便不删除代码所依赖的类型。

Answer 2

我通过在我的proguard规则文件的顶部添加-ignorewarnings来解决了这个问题。

Answer 3

尝试将packagingOptions添加到gradle中，尝试清理项目，删除build文件夹并重新重建，指定您在gradle中使用的所有jar文件。
