该应用程序适用于minSdkVersion 24,但在将其减少到minSdkVersion 19后,我得到的错误很少。在我的设备中运行它但在gradle sync时没有错误。错误日志已发布。依赖关系适用于minSdkVersion 24,但不适用于minSdkVersion 19,给我下面列出的错误,我需要它在minSdkVersion 19等较低版本上工作。任何帮助将不胜感激。

检查源兼容性和目标兼容性是否不是Java-8。将其设置为Java-8。
从gradle中删除这些行有助于删除错误并在我的手机上成功运行,使其在Android 7版本下运行

我无法解决上面的所有答案,但我找到了解决方案。我从libs项目文件夹中删除了库appcompat v4。
