Question

从27.1.1版本升级到v28.0.0 Android支持库后，我的构建失败，但出现以下异常：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'

原因：

Warning: androidx.media.AudioAttributesCompatParcelizer: can't find referenced field 'android.support.v4.media.AudioAttributesImpl mImpl' in program class android.support.v4.media.AudioAttributesCompat
Warning: androidx.media.AudioAttributesImplApi21Parcelizer: can't find referenced field 'android.media.AudioAttributes mAudioAttributes' in program class android.support.v4.media.AudioAttributesImplApi21

Warning: androidx.media.AudioAttributesImplBaseParcelizer: can't find referenced field 'int mLegacyStream' in program class android.support.v4.media.AudioAttributesImplBase

我尝试添加

-keep class android.support.v4.media.** { *; }

到我的Gradle配置，但错误仍然存在。

任何人都可以提供帮助吗？

谢谢

我不知道这是否是最好的解决方案，但是将这些行添加到我的proguard-rules.pro文件之后，它可以解决问题：

-dontwarn androidx.**
-keep class androidx.** { *; }
-keep interface androidx.** { *; }

迁移至v28.0.0支持库后，Android gradle构建失败
