当我右键单击我的 Android 项目并选择 Run->Android Application 时。模拟器启动并且更改确实反射(reflect)出来。
但是当我执行下面的命令时，它没有反应。
mvn clean install
mvn android:deploy
mvn android:emulator-start
此外，如果没有打开模拟器，则 deploy 和 emulator-start 命令会失败。

最佳答案
在 mvn android:deploy 之前运行 mvn android:emulator-start。 maven 插件无法部署到不存在的模拟器。在部署之前，您还必须等待模拟器启动。
使用 adb devices 检查连接到您计算机的 Activity android 设备。
关于java - Android Maven 没有启动模拟器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12874305/
