Phonegap run android命令挂起，尝试将应用程序安装到设备上

Question

I'm working on Phonegap for few days. Before this I was able to run phonegap apps into emulator through command line successfully, but now that's showing a peculiar hang; nothing happening no error, no flow of execution.

Now I'm running my apps by installing the .apk file directly through Android command line. But, still I want to know why it's not working, why this run command hangs there?

Answer 1

In my case ADB DEVICES displayed me invalid devices, an ADB KILL-SERVER solved this for me.

i suspect that is was caused by a my laptop going into sleep mode.

Answer 2

when it says trying to install app onto device the command is actually running adb install C:/yourpath/yourapp.apk which copies the app the android installation.

You shouldn't worry if it takes a long time. The installation is proceeding as planned, just be patient. The bigger your app, the longer is takes. For me a ~300MB app takes a full 7 mins to install to an attached device via USB. And the same app will take 13 mins to install to an Android emulator.

The emulator is known to be slow, there's a big SO thread regarding this issue here - Why is the Android emulator so slow? How can we speed up the Android emulator?
