WARNING : No target specified, deploying to emulator

Question

I'm trying to run an ionic app on my mobile phone (Android 4.4.2). USB-Debugging is activated.

When i run the command "ionic emulate android" everything works fine and the app is opend in the emulator.

But when I run the commad "ionic run android" I get following warning:

WARNING : No target specified, deploying to emulator

and the app is started on the virtual device...

Shouldn't the app run on my mobile phone? What am I doing wrong? How can I specify the target?

P.S.: When I copy the .apk file to the phone I can run the app.

Solution 1

I solved the problem.

Here is what I did: I typed into the command line: adb devices (located in the "platform-tools" folder in the Android SDK) which returned me an empty list.

So I installed my phone's drivers, which I downloaded from the vendors homepage.

Now the list contains my device and the app is started on my mobile phone.

Solution 2

I had another developer tool opened (Chrome Inspect) and it "ate" the connection. In my case, just closing the Chrome Inspect panel and running ionic run android worked.

Solution 3

I had a different problem, with a very simple solution.
When plugging in your Android device for the first time, it'll ask you to trust the computer's certificate. That popup screen disappeared on me, as I was just getting a call.

Simply unplugging/replugging your phone and accepting your computer's certificate should do the trick!

Solution 4

Once you've enabled your device for debugging, make sure to turn on usb tethering on the device;

Settings > Tethering & Networks > USB tethering

This fixed the problem for me.

Solution 5

In my case I had Android 5.1.1, and below are the steps I took:

• Please check that your PC recognizes your phone (you can access the files like in a USB flash drive). If not please install the drivers from google here.
• Please check that the USB debugging options is checked on your phone, then: 1- Go to Setting -> General -> '{} Developer options' 2- Look for the 'USB debugging' option 3- If the 'USB debugging' option is disabled then turn off 'Developer options' and turn it back on. Now you should be able to check the 'USB debugging' option.
