    <p>I took a fully working application and copied it and made it a library (Properties -> Android, Is Library). I also renamed this project to keep track of it separately - com.mylib.</p> <p>I then took the original application com.myapp and removed all the .java files except for one with some data (no actual code). I linked this up via Properties -> Android, and in the Library section added in the mylib library. It shows up with a green check. </p> <p>Changed the myapp's manifest activities to all have the library as the prefix as recommended by Google.</p> <pre><code>android:name="com.mylib.AppInfo" </code></pre> <p>Cleaned both the library and the project, and exited and restarted Eclipse as well. Compiles fine, and the program runs the main activity "AppInfo", but attempting to get to other activities always fails with ClassNotFoundException. </p> <p>I've also tried different name prefixes in the myapp manifest such as:</p> <pre><code>android:name="com.myapp.AppInfo" android:name=".AppInfo" </code></pre> <p>But these fail to get to the main app. Although no activity class names were changed in the library or the myapp manifest, I've reviewed them character by character to be sure they all match up both in case and exact letter.</p> <p>Using Eclipse under Windows 7 x64, and the app is set for minSdk of 11. Latest SDK tools also loaded (v20.0.3). Also Proguard is not being used (yet), and I'm using actual hardware (Android 4.0).</p> <p>I'm pulling my hair out trying to get the library to work. I have a completely different library and app pair working the same way on another project, and I've compared every property and option between the two libraries and projects and can't find anything that is missing or added that causes this to fail.</p> <p>Here's the full error from LogCat:</p> <pre><code>java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.myapp/com.myapp.LiveWallpaperSettings}: java.lang.ClassNotFoundException: com.myapp.LiveWallpaperSettings </code></pre> <p>Any suggestions or ideas on how to track this down? </p>

    1. COAfter you selected it as a library, it had the green check. once you clicked OK, and reopened the project settings, does it still appear as a green check? Does the library project's folder is in the same location as your project's folder?

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.
