我是新来的论坛，刚刚注册。我是阿根廷人，所以我的语法也许并不完美，但是却试图使我理解。 事情就是这样，一年前，我在Android Studio上制作一个应用程序，而我的朋友和我出于多种原因而停下来。现在，我们有一些时间来完成它，但是该项目的问题存在问题，我记得我当时解决了它。事情是我使用的api版本和SDK版本。 首先，必须为大量设备支持应用程序，并且我们不需要太多新事物。因此，我们的目标是尽可能获得最受欢迎的SDK（但是，我们确实需要使用我将在下面列出的API）。
我们使用的是SDK 26，并且该日期已正确构建。 现在，Android Studio建议更新到SDK 28，但我尝试这样做，但仍然失败 我将列出目前拥有的API和SDK ：（请记住推荐流行的SDK版本和该SDK的API版本）
apply plugin: 'com.android.application'

很抱歉，如果这是一个新手问题，或者如果我在线程的位置失败，但是如果有人帮助我，这将非常有帮助。 致以我的问候， 没有Xrless。
第二个结果：
应用插件：“ com.android.application”
