INSTALL_FAILED_DEXOPT permanently wrecking a project?
<p>I got this error attempting to install and test an Android build from eclipse:</p>

<p>Installation error: INSTALL_FAILED_DEXOPT</p>

<p>And logcat reveals this:</p>

<p>07-02 21:49:44.924: E/dalvikvm(863): Invalid type descriptor: 'Lcom/mypackagename/MyClass;'</p>

<p>So I delete the offending class and comment out the reference to it. Then it builds and installs fine. </p>

<p>Now that class name is forever cursed in this project. Even if I create a trivial subclass of java.lang.Object and give it that class name the error resurfaces. </p>

<p>Wiping and restarting the emulator doesn't help. Cleaning the project and restarting eclipse doesn't help. </p>

<p>How did things get screwed-up this badly, and what can I do to fix it?</p>
