Different Screen Size : <p>Hey guys i just wanna ask When ever we display a background picture in our activity we placed the picture in the drawable folder with sub different folder like </p>

<pre><code>drawable layout_hdpi or layout_mdpi or layout_ldpi or layout_xhdpi
</code></pre>

<p>and there is a specific density and dimension for each folder so that it can support multiple devices etc .</p>

<p>i want to ask that do i need to modify my picture for each folder like if my picture dimension is 3000*3000</p>

<p>first i have to modify it to 720*1280 for xhdpi and then put it in layout_xhdpi folder then i modify it for hdpi i.e 400*800 dimension and so on ..
It will take much time to do .Is There is any other easy method 
Thanks in Advance !!</p>
