Implementing Satellite Menu for Android ( classes could not be instantiated)

I added this object to my xml layout
<android.view.ext.SatelliteMenu
android:id="#+id/menu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="8dp"
sat:closeOnClick="true"
sat:expandDuration="500"
sat:mainImage="#drawable/ic_launcher"
sat:satelliteDistance="170dp"
sat:totalSpacingDegree="90" >
</android.view.ext.SatelliteMenu>
and recieve this error :
The following classes could not be instantiated:
- android.view.ext.SatelliteMenu (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
so i look in Log and i got these details

that this mean ?
when i run this project in the first time the object work fine and after this it do troubles

OPTION #1:
Sometimes, when a new resource is added, Eclipse doesn't compile correctly the new code (maybe a caching issue), causing this error.
Normally, simply restarting Eclipse is enough to fix the problem.
OPTION #2:
Sometimes, rendering custom views causes this exception. The only workaround I know is checking View.isInEditMode every time you try to use the getResources().
An example could be:
if (isInEditMode()) {
//do something else, as getResources() is not valid.
} else {
//you can use getResources()
String mystring = getResources().getString(R.string.mystring);
}

Embedding org.apache.cordova.CordovaWebView on Android throwing error

I am working with Phonegap, cordova-2.0.0 in an Android application. I want to use org.apache.cordova.CordovaWebView in my main layout. My main layout looks like the xml below.
Layout XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<org.apache.cordova.CordovaWebView
android:id="#+id/mainView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
/>
</RelativeLayout>
It is very simple test application and I followed the steps from http://docs.phonegap.com/en/2.0.0/guide_cordova-webview_android.md.html.
I followed all steps except creating cordova-x.x.x.jar file. I got cordova-2.0.0.jar from phonegap download and copied this jar file to the \libs folder.
If I remove the org.apache.cordova.CordovaWebView element from main layout, then it runs without exception.
Run as Android application produces the following error output.

It's an old topic but as I had the same problem and I could resolve it, I post the solution that permitted me to solve the problem if anyone has the same problem.
In the overrided function, getActivity() from CordovaInterface in the MainActivity, you have to implement it at less with these lines:
#Override
public Activity getActivity() {
return this;
}

Looks like config.xml is missing from your res/xml directory in your Android app.

Error while creating a bitmap xml in Android

I'm using android 3.0 and I try to create bitmap xml that will create a background by repeat of a pattern.
I called it pattern_4_4_repeat.xml and it is located in 'drawable':
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/pattern_base"
android:tileMode="repeat">
</bitmap>
It is working well and looks good when I run it. The problem is that I get an error in the Error Log that says the following:

I don't understand what am I missing here.
Thanks for your help

problem seems that #drawable/pattern_base is invalid (logcat says requires a valid src attribute )
ensure that drawable folder contains image with same name.

The problem was solved.
I've used ADT v14 when I had the problem, but after updating the ADT to v15 the error stopped showing in the Error Log.

main.xml: java.lang.NullPointerException Android Eclipse Error

So I just installed the Android SDK and the ADT addon for eclipse and ran into a problem.
When I go to the graphical layout in main.xml no layout shows up. Instead I just get this error

It doesnt matter what android version I am in I still get this error. I have tried uninstalling the SDK and the addon and to no avail. I am using SDK r14 tools and the ADT 14.0.
Anyone got any suggestions

Does it happen as soon as you open the XML file?
It may be worth checking the source in the XML file. Open the directory to where the file is contained and edit it (in Notepad etc) and just paste the following:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hi, did this work?" />
</LinearLayout>
That's about as simple as it gets. If that works, you know the XML in your current main.xml is wrong.
May also be worth rebuilding/cleaning your project.

Eclipse Grapic Layout: Unable to resolve drawable ... in attribute "background"

Hi. I'm adding a background xml file to an Imageview but i get this error in the Eclipse Graphical layout:
error! Unable to resolve drawable
"com.android.ide.common.rendering.api.ResourceValue#1ae0c2"
in attribute "background" Exception
details are logged in Window > Show
View > Error Log
When i run the widget on the device, the background is displayed in the right way, but the error in Eclipse is really annoying. The background file is:
<?xml version="1.0" encoding="utf-8"?>
<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/grey_back_tile"
android:tileMode="repeat" />
And here's where I use it:
<ImageView android:layout_gravity="top|center_horizontal" android:layout_marginTop="4dp" android:layout_width="286dp" android:layout_height="47dp" android:background="#drawable/widget_background_banner"/>
The error log stack trace shows:

Naturally the "grey_back_tile.png" is a valid resource, and it's located int the "drawable-hdpi" folder. Any clue to get rid of that error?

I know I am late to this but faced the same issue. I'm pretty certain it's an Eclipse ADT bug but to prevent the annoying errors, if you create a style and add a background item to your tiled background and refer the layout to that, as opposed to editing the background attribute on the layout, it should work and you won't get the annoying errors.
So, tiled background XML named app_background:
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/space" android:tileMode="repeat" />
Then a style, referring to it:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="TestBackground">
<item name="android:background">#drawable/app_background</item>
</style>
</resources>
And then assign the style to the layout:
style="#style/TestBackground"
