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

[runox]

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:

1. Sub
   
   Globals
   
2. 'These global variables will be redeclared each time the activity is created.
   
3. 'These variables can only be accessed from this module.
   
4. Dim
   
   ph As
   
   ICOSPhone
   
5. Dim
   
   btnMemory As
   
   Button
   
6. Dim
   
   lblAvail As
   
   Label
   
7. Dim
   
   lblTotal As
   
   Label
   
8. Dim
   
   lblUsed As
   
   Label
   
9. 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:

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

Now your activity when run will look like this below:

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

1. Sub
   
   btnMemory_Click
   
2. lblUsed.Text = ph.UsedMemory
   
3. lblAvail.Text = ph.AvailMemory
   
4. lblTotal.Text = ph.TotalMemory
   
5. 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:

Here's the full code for this tutorial:

1. Sub
   
   Process_Globals
   
2. 'These global variables will be declared once when the application starts.
   
3. 'These variables can be accessed from all modules.
   
4. End
   
   Sub
   
5. 
   
6. Sub
   
   Globals
   
7. 'These global variables will be redeclared each time the activity is created.
   
8. 'These variables can only be accessed from this module.
   
9. Dim
   
   ph As
   
   ICOSPhone
   
10. Dim
    
    btnMemory As
    
    Button
    
11. Dim
    
    lblAvail As
    
    Label
    
12. Dim
    
    lblTotal As
    
    Label
    
13. Dim
    
    lblUsed As
    
    Label
    
14. End
    
    Sub
    
15. 
    
16. Sub
    
    Activity_Create(FirstTime As
    
    Boolean
    
    )
    
17. 'Do not forget to load the layout file created with the visual designer. For example:
    
18. Activity.LoadLayout("main"
    
    )
    
19. End
    
    Sub
    
20. Sub
    
    Activity_Resume
    
21. End
    
    Sub
    
22. 
    
23. Sub
    
    Activity_Pause (UserClosed As
    
    Boolean
    
    )
    
24. 
    
25. End
    
    Sub
    
26. 
    
27. 
    
28. Sub
    
    btnMemory_Click
    
29. lblUsed.Text = ph.UsedMemory
    
30. lblAvail.Text = ph.AvailMemory
    
31. lblTotal.Text = ph.TotalMemory
    
32. End
    
    Sub
