Question

我的Android应用使用Google地图，可以很好地编译SDK23和SDK19设备。它在SDK23（LG G4）上运行良好，但生成此错误SDK19设备（Samsung Galaxy 4）=＆gt; java.lang.NoClassDefFoundError：com.google.android.gms.R $串

这些是我的依赖项： Android Studio Dependencies

我的清单文件：

         The API key for Google Maps-based APIs is defined as a string resource using the <meta-data> tag

         Note that the API key is linked to the encryption key used to sign the APK.
         You need a different API key for each encryption key, including the release key that is used to
         sign the APK for publishing.
         You can define the keys for the debug and release targets in src/debug/ and src/release/.

当我搜索此错误时，我无法找到解决方案/回答为什么我的应用程序在SDK23下编译/运行正常，但在SDK19下生成此运行时错误。

任何帮助将不胜感激！

Answer 1

请尝试清理您的项目，然后从App Gradle中删除最后两个依赖项：play-services gcm an identityities

Answer 2

终于解决了这个问题。

我需要降级清单编译'com.google.android.gms：play-services：8.4.0' 到旧版本编译'com.google.android.gms：play-services：8.3.0'以确保与两台设备上的设备软件兼容。

该应用程序现在可在SDK19和SDK23手机上运行。感谢Mounir指出我正确的方向。非常感谢！
