Question

我使用samsung knox sdk并更新knox版本（2.7.1）。这个错误出现在尝试编译我的应用程序时。

错误明细：

错误：将字节码转换为dex时出错：原因：Dex无法解析版本52字节代码。这是由具有的库依赖性引起的使用Java 8或更高版本编译。如果你正在使用＆＃39; java＆＃39; 库子模块中的gradle插件添加targetCompatibility =＆＃39; 1.7＆＃39; sourceCompatibility =＆＃39; 1.7＆＃39;到该子模块的build.gradle文件。 ...解析时机器人/应用/企业/ knoxcustom / CustomDeviceManager.class

我添加了compileOptions但又一次获得异常。你能救我吗？

Answer 1

你改变了

compileOptions.with {
            sourceCompatibility = JavaVersion.VERSION_1_7
            targetCompatibility = JavaVersion.VERSION_1_7
        }

到

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
