How to run or debug on android phone instead of emulator?

Question

Android emulator is so slow that it is not possible to test run applications. Is there anyway to debug/run applications on real phone with IDE instead of emulator?

Answer 1

Enable USB-Debugging on your phone. Connect it to your computer. ADB should recognize it and you can use it the same way as a virtual device.

If ./adb devices lists your phone as a lot of question marks, then it is lacking some permissions. To fix this, restart the adb server as root. Something on the line of:

~$ ./adb devices
List of devices attached 
emulator-5554   device
?????????????   device  <--- your phone
~$ sudo -s
~# ./adb kill-server
~# ./adb devices
List of devices attached 
emulator-5554   device
1232345345345   device  <--- your phone
