Configuring ADB:

By ensuring the smartwatch is coupled, connect your smartphone or tablet to your PC and check that it is recognized by adb with the command:

adb devices
The response to this command should give you a numeric code supported by the device name.

Tests the connection type in the following commands:

Install app on android smartwatch wear:

If you have successfully completed the steps now your smartwatch is ready to receive commands(See Screenshot above) adb and send any app will be very simple.

1.Simply arrange the apk (from legal sources and official) of the app you want to install  and place it in the folder adb.

2.Disconnect your smartphone or tablet from the USB port and with the following command you can proceed with the installation:

adb -e install filename.apk

3.Instead of “filename” you can just replace the actual name of the file. At the end of the process you should see the message “Success” and your app will already be present and bootable on smartwatch.


Set a resolution (DPI) customized:

To allow visualization “regular” of the app, on the small screens of smartwatch we can play on the density virtual screen (before be sure to know what the original of your smartwatch). Even this is possible thanks to a command:

adb -e shell density wm 240

Instead of 240, you can enter the desired value. One less than the default (eg. 240 for LG G Watch like in image below) allow you to have more items on the screen, at the price of a loss of readability on smaller characters.



Ending an app:

When you have finished using the app and want to get out of it you can use two methods.

1.The simplest, but not always working, plan to make a double tap on the screen

2. You’ll have to use the following command adb:

adb -e shell am force-stop nomepacchettoapp

The package name of the app is traceable with the command:

adb shell ps -e

Once completed you can use to restore the original resolution of the device, using the command specified in the relevant section of this guide. Remember also that the app for smartphones and tablets are not optimized for the processors and the batteries of the devices Android Wear, so keep the charger always on or the battery  will very soon.
