Develop Reference

Android Application Project not working in Eclipse

I am having a lot of trouble trying to setting up the Android Development tools in Eclipse.
FYI: I am using a PC (64-bit Windows 7)
I tryed for a long time then uninstalled eclipse and reintalled it. I had Juno and the tutorial I was following was using Indigo so I switched, but the problem was still there.
I found a post that said to delete to keystore and restart, that didn't work.
I have been doing this for hours and I am fed up. does anyone know what is wrong? All the solutions when I google "Failed to load properties file for project" do not help...but it is the same error.
Tutorial I am following: http://www.newthinktank.com/2013/04/install-android-development-tools/
Here is the error I get when the emulator tries to start...
Exception raised during rendering: Could not find bool resource matching value 0x1110013 (resolved name: config_ui_enableFadingMarquee) in current configuration.
Exception details are logged in Window > Show View > Error Log

There are also a bunch of other errors after that, here are some, has anyone ever seen this before???

And some with long stack traces:

I suggest you to try to install the bundle, that includes Eclipse and the Android SDK. You can find the instructions to install it at http://developer.android.com/sdk/installing/bundle.html. I downloaded it on my pc with Windows 7 (64 bit), and it worked like a charm.

Whenever I try to use content assist on findViewById(), the code doesn't get completed. It just stays the same as it was. When I look at the error log, it shows this:

I am on Eclipse-Juno. I sometimes get this error using the View.onClickListener content assist. But the error happens less often. The error log also shows that the plugin responsible is org.eclipse.ui. However, I don't see that plugin on my eclipse/plugin folder. I only see org.eclipse.ui.intro.universal_3.2.600.v20120912-155524
In addition, I also get the "Unhandled event loop exception" when using content assist for View.onClickListener Inner Type.
I found a somehow similar problem. It was reported as a bug in eclipse. Here is the link:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=207496

I got it! I moved the eclipse folder into another location (my Desktop) and BOOM! No more errors! I managed to use the content assist without returning an "Unhandled event loop exception". Maybe the location was crowded with too many files.

Can't rename application package without an error message on one project

============update=============
I was able to edit all 18 classes in my application manually one at a time and get it published under a new name but this is not really an acceptable long term solution. I would still like to know how to fix this problem. As I said, I am able to change the package name of other applications, just not the one I care about.

I go to "application tools" then "rename application project" and I can rename a package except for the one I want to rename. In that case, I get an exception:
The box that pops up is called Refactoring
The heading in the box is A fatal error occurred while performing the refactoring.
And the error message is:
"An unexpected exception occurred while creating a change object. See the error log for more details."
Nothing shows up in the error log and I have no idea what to do. I can easily rename other projects so I think I know the process. The application works fine and in fact is released on Google Play. I want to create a second version for testing that times out in 10 days for people to try so it needs a different name. Just changing the name in the strings file is not enough for Google Play to think it is a different project.
Almost any work around that can get this thing on Google Play as a different application would be just fine.
Any help would be appreciated as most of the posts deal with how to change the name when there is no error, which I can do.

The problem with mine is because I have a code file that is totally commented off, when the re factor tool scans through the files under my package it couldn't read it. Check through your codes make sure the .java files are all valid java files.

Reinstalled Eclipse. Nothing else worked.

Eclipse Juno - Assertion Failed (Problems occurred when invoking code from plug-in: "org.eclipse.jface".)

I recently installed Eclispe Juno for Java for Android. I usually press . after a class name to know the associated methods, in case I wish to choose some other method instead of one already chosen from this list the following error pops up in the IDE.
How can tell IDE that this is not an error and there is no need to pop this message again and again?
The following is the error log from Eclipse

As mentioned before, the problem is caused by the plugin Coffee-Byte plugin for Eclipse. I managed to work-around the problem, for myself at least; disabled everything except Import Statements, Source Headers, Javadocs, and User Defined Regions. I had to manually add regions to the template of methods to get them to fold automatically, but it's a small price to pay for having custom folding.
Also, if anyone is interested in fixing it, the error only occurs if Report problems as you type is enabled in Preferences->Java->Editor. If disabled, then all types of folding work.
Update: I'm currently using Eclipse version Kepler Service Release 1, and build id 20130919-0819. I've re-enabled Normal Methods, Constructors, and Getters and setters; so far, the assertion error hasn't appeared. It seems that the problem has been fixed.

Looks like the problem was caused by Coffee-Byte plugin of Eclipse (plugin used for folding) http://kosiara87.blogspot.in/2011/12/how-to-install-coffee-bytes-plugin-in.html?showComment=1341091754230#c8853438068212069468.

"Unhandled Event Loop Exception" when doing anything in Android XML

I'm getting this "Unhandled Event Loop Exception" error when I do very minimal things with my xml layout in Android (Eclipse 3.6.2). Everything I do makes this error come up. And the dialog box will be something like "Error...35" or something. It's as simple as moving an ImageView around in the Graphical Editor or even typing xml (every keystroke creates a new error). It's not just one error either. it's 7 or 8 of these "Unhandled Event Loop Exception" errors all in a row.
Here's the code inside the Error Log errors.

I found the same issue,but it works fine when i Closed and restarted my Eclipse

If this happens on any XML file, then it is probably a problem in the XML editor. Either way, if you try editing the XML with the built-in plain text editor, it may work. Also, if it is a bug of any kind, updating eclipse and the android plug-in may help. Eclipse 3.7 is out.
