    <p>I've been trying to make a simple live wallpaper out of a boot animation. So basically i have about 50 .pngs in my drawable folder. I'm able to set the animation to about 10-20 frames and it works great. But once i set it to about 30 frames...I get an OutOfMemory Error. I was hoping maybe someone could take a look at my code and maybe give an example of how I could achieve more frames? That would help so much i've been looking at this for hours > &lt;</p> <p>Here's my code:</p> <pre><code>package com.androidnetwork.animlivewp; import android.content.res.Resources; import android.graphics.Bitmap;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
