我似乎遇到一个问题，让一个应用程序运行在运行低于Lollipop的AVD上。我将最小的SDK设置为Jellybean（4.2），但每当我尝试使用Jellybean或Kit Kat在AVD上运行它时，它就会崩溃。
我已经看到其他人在这里遇到这个问题并且可以通过multidex解决但是我遇到了这个问题，即使应用程序只包含默认的＆＃34; Hello world＆＃34;首次创建空白活动时的内容。
我创建了一个带有空白活动的演示项目，并且完全没有改变它，但它仍然崩溃。
这是它给出的错误代码：

看着它，我认为它可能是应用程序主题的一个问题，但改变它并没有改变任何东西。我对Android非常陌生，所以我不太确定这可能是什么。
任何建议都将不胜感激。
编辑：我可能还应该补充一点，我使用的是Android Studio，以防万一。
答案 0 :(得分：0)
在defaultConfig
中添加GradlevectorDrawables.useSupportLibrary = true
还要确保您的Activity扩展了AppCompatActivity，而不是普通的Activity。
