I am building an andorid application that has 8 buttons and I have use very small sized png images for the backgrounds. The size of all images is only 355 kb but when I run the application it gives me error saying

java.lang.OutOfMemoryError: Failed to allocate a 256000012 byte allocation with 16777216 free bytes and 119MB until OOM

Why does it takes so much memory? Is there any better way to use less memory? This is how I made the button in my xml. Thank You 

           <Button
            android:id="@+id/groupmeButton"
            android:layout_width="70dp"
            android:layout_height="70dp"
            android:layout_alignParentLeft="true"
            android:layout_gravity="center"
            android:layout_marginLeft="50dp"
            android:background="@drawable/image1"
            android:onClick="onClick"
            />

First, image1 is too large in terms of resolution (pixels wide, pixels high).

Second, you probably put image1 in res/drawable/. res/drawable/ is a synonym for res/drawable-mdpi/, meaning that drawables in res/drawable/ are designed for mdpi screens. If you run your app on a higher-density screen, Android will upscale the image to adapt to the higher density. Instead of putting drawables like PNGs and JPEGs in res/drawable/, either:

  • Have different versions of the same image for different densities. The Image Asset wizard in Android Studio can set this up for you.

  • Or, put the image in res/drawable-anydpi/, to tell Android not to upscale or downscale the image.

You can you vector Drawable now as Android is supporting Vectors as well. To support vector below API level 21 you can follow below official link.

https://developer.android.com/studio/write/vector-asset-studio.html

Probably that can help you to avoid huge memory for images.
