Why isn't my Android app working when I test it on a real device?

Question

I'm building an Android app with Ionic Framework, and am trying to run it on a real device with USB debugging, like in these tutorials:

http://www.neilberry.com/how-to-run-your-ionic-app-on-real-devices/?s=2015-08-24-how-to-run-your-ionic-app-on-real-devices

http://junerockwell.com/how-to-run-ionic-on-real-devices/

Step-1

$ ionic platform add android

$ ionic build android

After adding the Android platform and building an APK with the above commands, it works correctly with no error. So, I try the next step:

Step-2

I connected device and PC via Debugging mode to run android devices. I ran the command ionic run android. I get the below error messageL

$ ionic run android

ANDROID_HOME=C:\Android\sdk JAVA_HOME=C:\Program Files\java\jdk1.8.0_25 WARNING : No target specified, deploying to emulator WARNING : no emulator specified, defaulting to Nexus_5_API_23_x86 Waiting for emulator... emulator: ERROR: x86 emulation currently requires hardware acceleration! Please ensure Intel HAXM is properly installed and usable. CPU acceleration status: HAX kernel module is not installed!

How can I solve this problem?

List of my ionic info:

$ ionic info

Your system information: Cordova CLI: 5.4.1 Gulp version: CLI version 3.9.0 Gulp local: Local version 3.9.0 Ionic Version: 1.2.4 Ionic CLI Version: 1.7.13 Ionic App Lib Version: 0.6.5 OS: Windows 8.1 Node Version: v4.2.4

Why don't you use Android Studio for this task? It is easier to handle then using the command line. — Joerg, Jan 22 '16 at 05:52
I solved, after installed my phone's driver on PC, check devices list that `adb devices`. — lwinkyawmyat, Nov 16 '16 at 02:29
try to install android studio then open the platform/android folder from you source folder then debug it and resolve your error this the best way to rectified you errors — Zaza, Sep 12 '17 at 11:56

I don't use ionic, I use cordova. In cordova you call the emulator by:

cordova emulate android

and to run the app on a device:

cordova run android --device

Maybe you try:

ionic run android --device

In ionic, "ionic run android" will try to run on the connected Android device. If no such device is found, it will launch the emulator (similar to calling "ionic emulate android"). – user276648 May 12 '16 at 09:34

Maybe you can try running adb start-server. I know I need to do this first before being able to see my device in chrome://inspect/#devices. You of course need adb which probably comes from the Android SDK.

This error isn't related to ionic frameworks because HAXM installer isn't installed on Android SDK Manager.

This question already has an answer here: Error in launching AVD with AMD processor.
