Full screen image size in Android activity

Question

I'm developing a welcome page for my application that would display a full screen image in an activity, along with two buttons. Very much like the welcome screen of Instagram. I understand that you have images for these modes in Android namely ldpi, mdpi, hdpi, and xhdpi. So my question is, what are the each modes maximum resolution and how do I create images that don't stretch up on multitude of screen resolutions and DPI settings? I've read the official Android guide, supporting multiple screens , though much useful, the article didn't answer my question. Hoping to learn it from here.

Thank you! PS: I won't be supporting landscape orientation for welcome screen of my application.

Answer 1

Well, basically you have different screen densities in android, so you need to add images in different resolutions on each drawable folder, for instance:

• xlarge screens are at least 960dp x 720dp (drawable-xhdpi)
• large screens are at least 640dp x 480dp (drawable-hdpi)
• normal screens are at least 470dp x 320dp (drawable-mdpi)
• small screens are at least 426dp x 320dp (drawable-ldpi)

In your Activity onCreate()

 requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                                WindowManager.LayoutParams.FLAG_FULLSCREEN);

or in the AndroidManifest.xml Alternatively you can add

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

to AndroidManifest.xml under
