java - Android 5.x ClassNotFoundException 在 6.0+ 上运行良好

Question

我已将项目的 minSdkVersion 从 19 更新到 21。这导致我无法运行应用程序的 5.0/5.1 设备出现问题。我在我的 Application 类上不断收到 ClassNotFoundException。完整的日志、应用程序类和 gradle 文件如下。如果我将我的项目恢复到 minSdkVersion 19，那么应用程序将在 4.4+ 上运行而没有问题。

我的尝试

• 清理/重建

• 更新和降级构建工具版本

• 跨项目的所有支持库都具有相同的版本号

• 将我的所有 list 类设为相对然后绝对

• 更新了所有 SDK 和构建工具

Answer 1

当面向 api 21 时，编译器将读取 100 个 dex 文件的限制。因此，我发现一个简单的解决方案是将其添加到 gradle 文件中的 dexOptions 中。这会将您的所有 dex 文件合并到尽可能低的数量。

在您的 build.gradle 文件中添加以下内容

android {
    ...
    dexOptions {
        preDexLibraries = false
    }
}
