How to display Total Memory, Used Memory, and Available Memory in your Android Phone using Basic4Android

Submitted by donbermoy on Friday, January 31, 2014 - 21:09.

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. This has the dual benefit of increasing the general responsiveness of Android devices, since apps don't need to be closed and reopened from scratch each time, but also ensuring background apps don't consume power needlessly. Thus, it is really important to manage our memory in Android phones. On this, you need to create Three Labels and named it as "lblAvail" for displaying the Available Memory, "lblTotal" for displaying the Total Memory, and "lblUsed" for displaying the Used Memory. You need also to create one button and named it btnMemory to display all of this memory in one. Next, named your abstract design as "main". Your abstract designer will be like this one below:

Declare your variable in the Sub_Global like this:

Sub Globals
        'These global variables will be redeclared each time the activity is created.
        'These variables can only be accessed from this module.
   Dim ph As ICOSPhone
        Dim btnMemory As Button
        Dim lblAvail As Label
        Dim lblTotal As Label
        Dim lblUsed As Label
End Sub

Dim ph As ICOSPhone - ph here is our variable for ICOSPhone in which it has all the necessary libraries in using phone utilities. Dim lblAvail As Label - we use this label to display the the Available Memory of your phone. Dim lblTotal As Label - we use this label to display the the Total Memory of your phone. Dim lblUsed As Label - we use this label to display the the Used Memory of your phone. Now create a new activity. It should look like this:

Sub Activity_Create(FirstTime As Boolean)
        'Do not forget to load the layout file created with the visual designer. For example:
        Activity.LoadLayout("main")
End Sub

Now your activity when run will look like this below: firstRun

Next, type the following code below. That this code means to display the all the values of our memory when our btnMemory is click.

Sub btnMemory_Click
        lblUsed.Text = ph.UsedMemory
        lblAvail.Text = ph.AvailMemory
        lblTotal.Text = ph.TotalMemory
End Sub

The ph.UsedMemory here is the method used to display the Used Memory, ph.AvailMemory for displaying Available Memory, and ph.TotalMemory for displaying Total Memory. When you click this button, it will display like this image below: finalImage

Here's the full code for this tutorial:

Sub Process_Globals
        'These global variables will be declared once when the application starts.
        'These variables can be accessed from all modules.
End Sub
 
Sub Globals
        'These global variables will be redeclared each time the activity is created.
        'These variables can only be accessed from this module.
   Dim ph As ICOSPhone
        Dim btnMemory As Button
        Dim lblAvail As Label
        Dim lblTotal As Label
        Dim lblUsed As Label
End Sub
 
Sub Activity_Create(FirstTime As Boolean)
        'Do not forget to load the layout file created with the visual designer. For example:
        Activity.LoadLayout("main")
End Sub
Sub Activity_Resume
End Sub
 
Sub Activity_Pause (UserClosed As Boolean)
 
End Sub
 
 
Sub btnMemory_Click
        lblUsed.Text = ph.UsedMemory
        lblAvail.Text = ph.AvailMemory
        lblTotal.Text = ph.TotalMemory
End Sub
