This problem I found is the SDK version of the problem, I directly tried a variety of SDK, to see which one is suitable, the current SDK 20 out, I found that there will be a problem, I went back to use SDK 18, the problem quickly solved, if this doesn't work, have a"+" sign in the SDK option, as shown above, and try another version.

这个问题我发现是sdk版本的问题，我直接尝试了各种sdk，看看哪一种合适，目前sdk20出来了，我发现用了就会出问题，我回去用了sdk18，问题快速解决了，如果这个还不行，在sdk选项中有个“+”号，如上图，尝试其他版本。
