Good day! This is my other tutorial on controls. The one that i had tutored was the AutoCompleteEditText, and now the Spinner. Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one. Spinner is the same as ComboBox in Visual Basic. On this, you need to create one Label to have a result when you choose an item in the Spinner. Named it as tgtLabel.

Hi! this is an another tutorial in Android using Basic4Android that will view WiFi settings in your phone and can customize to enable/disable your WiFi. This tutorial deals with several categories of items:

• The list of configured networks. The list can be viewed and updated, and attributes of individual entries can be modified.
• The currently active WiFi network, if any.

This is my other tutorial on how to find and display your available memory, used memory, and total memory in your phone. Since Android devices are usually battery-powered, Android is designed to manage memory (RAM) to keep power consumption at a minimum, in contrast to desktop operating systems which generally assume they are connected to unlimited mains electricity. When an Android app is no longer in use, the system will automatically suspend it in memory – while the app is still technically "open", suspended apps consume no resources and sit idly in the background until needed again.

Good day! This is my other tutorial on how to find and display your Android OS Version and your Device Android Model.

Today, the latest Android version is the Android KitKat 4.4.
