强调一下哈，MainActivity创建项目之后就自动生成了，Manifest中也有的，然后什么都不动跑过一次，APP不会崩掉，加了Retrofit之后崩掉了
已解决，感觉我每天都有一问，跟拉锯哥视频上呈现出来的错误不太一样，但用一样的方法解决了
compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }如果有小伙伴也在学Retrofit！！一定要跟着拉锯哥的视频走！！照做就完事了！！
D/HwFLClassLoader: USE_FEATURE_LIST had not init!
呸，百度了一下那个是华为渲染问题，不过APP崩掉的原因是活动问题，但活动又都声明注册了，没明白咋整
