所以我尝试将android模拟器用于我的离子应用程序，因为我需要尝试使用他们的Web服务器方法无法实现的sqlite。
反正。我做了什么：
cd myProject
离子cordova build android =＆gt;成功
离子cardova模拟android

所以我确实有avds - 没有？
问题是什么？
答案 0 :(得分：1)
我认为你的路径不匹配。尝试明确指定avd
答案 1 :(得分：0)
我用以下方法解决了同样的错误：
ionic cordova platform rm android
ionic cordova platform add android@7.1.0
并运行Android模拟器（来自终端或Android Studio），然后使用离子cordova模拟android
