Answer 1

在你的gradle中加上这个。

android {
        packagingOptions {
            exclude 'META-INF/DEPENDENCIES.txt'
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/maven/pom.properties'
            exclude 'META-INF/NOTICE.txt'
            exclude 'META-INF/NOTICE'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/notice.txt'
            exclude 'META-INF/license.txt'
            exclude 'META-INF/dependencies.txt'
            exclude 'META-INF/LGPL2.1'

        }
    }

在proguard-rules.pro添加

-dontwarn com.kosalgeek.android.photoutil.**

并将true设置为minifyEnabled true 可能这会有所帮助。

Answer 2

正如我所看到的，您已经在发布版本中启用了proguard，因此通过pruguard获取警告非常常见。

在您的情况下，这些与lib com.kosalgeek.android.photoutil有关。我认为你应该使用 -dontwarn 作为上面提到的Devendra。

如果这不起作用，那么您可能应该为您的库找到正确的proguard规则。
