The Redmi Note 4G has a 5.5 inch screen, placing it on the larger end of smartphone screens. Because its screen is over 5.3 inches, this phone also qualifies as a phablet.
You can install .apk files to emulator regardless of what you are using (Eclipse or Android Studio). here's what I always do: (For full beginners).1- Run the emulator, and wait until it's completely started.- now open run.bat and write adb install your_apk_file.apk. 6- wait until the installation is complete. 7- voila your apk is installed to your emulator. Note: to re-install the application if it already existe use adb install-r your_apk_file.apk. sorry for the detailed instruction as I said for full beginners.
Choose media device. Then, simply find your phone's folder on your computer (it will be in My Computer or Computer on Windows machines) and copy the APK file into a folder of your choice in your Android smartphone. You will now be able to search for the file location in the my files folder on your device.pk files, are like .exe (executable) files on a pc, with some differences. When you install software on a pc, it loads the program, with all of the files it needs to operate on your pc, and the .exe, is the working part of the program (dlls are the libraries).
