<h2 id="gesturebuilderinstall">I can't install the GestureBuilder sample 

app in the emulator</a></h2>

<p>This is similar to the ApiDemos problem described above, except that

you cannot fix it by uninstalling GestureBuilder from the emulator. The 

GestureBuilder app cannot be uninstalled because it is currently installed 

within the system files themselves.</p>

<p><strong>Symptoms</strong></p>

<ul><li><p>You cannot run GestureBuilder in the emulator:</p>

<pre>[2009-12-10 14:57:19 - GestureBuilderActivity]Re-installation failed due to different application signatures.

[2009-12-10 14:57:19 - GestureBuilderActivity]You must perform a full uninstall of the application. WARNING: This will remove the application data!

[2009-12-10 14:57:19 - GestureBuilderActivity]Please execute 'adb uninstall com.android.gesture.builder' in a shell.</pre>

</li>

<li><p>Running <code>adb uninstall com.android.gesture.builder</code> fails:</p>

<pre>$ adb uninstall com.android.gesture.builder

	Failure</pre>

</li></ul>

<p>For now, the work-around is to change the sample's package name

so that the system can install it as a new app rather than as a 

replacement for the existing GestureBuilder app. To change the 

package name, open the manifest file and modify the package attribute 

of the manifest element. Next, update imports and other references to 

the package name, rebuild the app, and run it in an AVD.</p>

<p>For example, here's how you could do this in Eclipse:</p>

<ol>

  <li>Right-click on the package name

(<code>src/com.android.gesture.builder</code>).</li>

  <li>Select <strong>Refactor &gt; Rename</strong> and change the name, for example to

<code>com.android.gestureNEW.builder</code>. </li>

  <li>Open the manifest file. Inside the <code>&lt;manifest&gt;</code>

tag, change the package name to

<code>com.android.gestureNEW.builder</code>.</li>

  <li>Open each of the two Activity files and do Ctrl-Shift-O to add

missing import packages, then save each file.</li>

<li>Run the GestureBuilder application on the emulator.</li>

</ol>

<p>If you get an error message such as "Could not load /sdcard/gestures. 

Make sure you have a mounted SD card," be sure that your target AVD has an 

SD card. To create an AVD that has an SD card, use the

<a href="{@docRoot}guide/developing/tools/avd.html#options"><code>-c</code> 

option</a> in the <code>android create avd</code> command.</p> 

<h2 id="signingcalendar">I can't compile my app because the build tools generated an expired debug certificate</h2>

<p>For general information about signing Android applications, see 

<a href="{@docRoot}guide/publishing/app-signing.html">Signing Your Applications</a>. </p>

<h2 id="manifestfiles">Unable to view manifest files from within

Eclipse</a></h2>

<p>When you try to open an application's manifest file from within

Eclipse, you might get an error such as this one:</p>

<pre>An error has occurred. See error log for more details.

org.eclipse.wst.sse.ui.StructuredTextEditor.isBlockSelectionModeEnabled()Z</pre>

<p>Try reverting to the 3.0 version of the Eclipse XML Editors and

Tools. If this does not work, remove the 3.1 version of the tool. To do

this in Eclipse 3.4:</p>

<ol>

	<li>Select <strong>Help > Software Updates...</strong></li>

	<li>Select the <strong>Installed Software</strong> tab.</li>

	<li>Select <strong>Eclipse XML Editors and Tools</strong>.</li>

	<li>Click <strong>Uninstall</strong>.</li>

	<li>Click <strong>Finish</strong>.</li>

</ol>

<p>When you restart Eclipse, you should be able to view the manifest

files. </p>
