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

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
$java.lang.NullPointerException

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.

how to add Facebook latest Android SDK into Eclipse

I'm trying to integrate the Facebook SDK with my Android project with Eclipse.But as we know the latest Facebook SDK is in .aar form and it is supposed to be used in Android Studio.But for some reason i have to continue working with Eclipse.
I tried to extract the .jar file and the res folder and drop them into my project directly,but then my project was full of errors,like classed couldn't be found and such.
So here is one error that appeared when i tried to add a LoginButton to my activity_main.xml
<com.facebook.login.widget.LoginButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"

Trying to integrate Tap for Tap in my Application

I am trying to integrate tap for tap in my application. I am following their documentation from here: https://tapfortap.com/doc/android/integration. Everything seems fine up to when I added:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.tapfortap.Banner
android:id="#+id/banner"
android:layout_width="320dip"
android:layout_height="50dip"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>
I get the following message in the graphical layout:
com.tapfortap.Banner failed to instantiate.
and in the error log:

However thier website says that my app is registered, but I am not able to see any ads if I test it on a device or emulator, however I have added the testing meta tags in my Manifest and all thier permissions.
In Activity:
TapForTap.initialize(this, "*******************");

Thats because there is no class called com.tapfortap.Banner.
You need to use com.tapfortap.sdk.Banner from the new zip file https://github.com/tapfortap/Android/archive/master.zip.
Extract the zip file and again extract TapforTap.aar, you will get classes.jar use that in your program.

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);
}

What could be the problem?

right click your android project choose Android Tools-> Clear Lint Markers
then again run Lint once.

Found this Link.
It was a Bug in the Lint tool. It has been fixed in the latest ADT 16.0.1 release.

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:
org.xmlpull.v1.XmlPullParserException: Binary XML file line #4: <bitmap> requires a valid src attribute

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.
