Eclipse Android Project Error

Question

Trying to run my Android App and Eclipse (in Windows 7) is throwing up an error. Yesterday I had no problem so I can't think what I could have done to caus eit. The error message is

**Your project contains error(s), please fix them before running your application.**

Well, I went to window->view->error log and I found this

Warning
While loading class "com.android.sdklib.internal.project.ProjectProperties", thread "Thread[main,6,main]" timed out waiting (5000ms) for thread "Thread[org.eclipse.jdt.internal.ui.text.JavaReconciler,1,main]" to finish starting bundle "com.android.ide.eclipse.adt_11.0.0.v201105251008-128486 [317]". To avoid deadlock, thread "Thread[main,6,main]" is proceeding but "com.android.sdklib.internal.project.ProjectProperties" may not be fully initialized.
org.osgi.framework.BundleException: State change in progress for bundle "reference:file:plugins/com.android.ide.eclipse.adt_11.0.0.v201105251008-128486.jar" by thread "org.eclipse.jdt.internal.ui.text.JavaReconciler".
at org.eclipse.osgi.framework.internal.core.AbstractBundle.beginStateChange(AbstractBundle.java:1073)

I would like ot add that although the project itself is showing an error no source file or resource has an error.

SO far I have tried:

clean/build (several times)

close eclipse and reopen (several times)

shutdown computer and restart

Thanks in advance.

EDIT:

Tried again and got the following message in console:

[2011年08月14日 00:40:47 - Dex Loader] Unable to execute dex: wrapper was not properly loaded first [2011年08月14日 00:40:47 - MyAppName] Conversion to Dalvik format failed: Unable to execute dex: wrapper was not properly loaded first

Don't know it cant convert to Dalvik format. The SDK is in the build path.

• MByD: This problem usually indicates that you need to include some jar that you use in your build path.
• sherif: do other android projects work ?
• user485498: @sherif. I tried to run another project and now all Android projects are showing the same error. I can't run any of them.
• user485498: @MByD. Thanks, but I am not using any outside jar files. Just the Android SDK and the class files in my project.
• sherif: ok then there is a problem with your sdk or with the plugin try to reinstall both shoud do the trick

Answer 1

After much stress and pain and me almost throwing my computer out the window I found the problem is in the debug.keystore file. Although Eclipse gave me no warning of this. After deleting the debug.keystore file I cleaned/build my project.

Eclipse gave the following error.

Re-installation failed due to different application signatures.

[2011年08月14日 13:16:42 - MyApp] You must perform a full uninstall of the application.

WARNING: This will remove the application data!

[2011年08月14日 13:16:42 - MyApp] Please execute 'adb uninstall com.etc.etc' in a shell.

[2011年08月14日 13:16:42 - MyApp] Launch canceled!

I didnt follow the advice but simply renamed my package. It works now. I'm not sure what to do with older packages that I have released onto the Market. It will be difficult to add new versions if I have to rename them to test them on the emulator/my phone.

• Jeff Hay: The uninstall warning you are getting there is just on the test device (or emulator image) that you are using - the same app can't have two different signatures (debug and release) on the one device. It will work fine for the market.

Answer 2

feels to me something wrong with the SDK. Why dont you uninstall the current Android sdk and install a new version instead.

Answer 3

Right-click on your Project in Eclipse and choose Properties. Check in the Java Build Path that you have the Google API's in the Libraries tab. Check the references to them.

• user485498: Hmmm... I checked the SDK in the build path (please see my edited question). It says Access rules: 1 rule defined, Forbidden. Presumably this is undesirable, although I dont know how to change it.
• John J Smith: Out of interest, in Eclipse, does your project folder have a little 'a' above it or a 'J' ?
• user485498: 'a'. It is an android project. The project has the dreaded red x, but all source files are fine.I am at the point of thinking about reinstalling eclipse and the sdk.
