@ngocle92dn Yes, it's just a regular app (and a small one at that at 30 kB!).
Normally I install apps over ADB.
Code:
C:\>adb install Lights-Alpha2.apk
ADB is part of the big Android Studio, but you don't need a GB of stuff.
Just Google "minimal ADB" and you can find a download of the 2.5 MB file adb.exe
You could just transfer apps over just like you transfer books, then use a file explorer on your device to click it.
Then, as the app is installed somewhere else you can (should) delete what you copied over.
Still, once you get ADB working you'll appreciate the one step install.
@kndlewis You'll find that adb.exe is installed in Android Studio somewhere like Android\SDK\platform-tools\adb.exe
You can set the environment PATH to include that or use DOSKEY to set up a macro or CD to the directory or simply type out the whole C:\Programs....
Code:
C:\>adb devices
