Android app does not start in emulator or device

I have finally finished my app and everything was working fine. I went back to add in the admob stuff and now it will not start in the emulator. it says it successfully installed the app on the emulator but it does not launch and the icon is not visible to try to manually run. I think the manifest is where my error is but I am unsure.

It looks like your main activity name is incorrect. Java is case sensitive and your application package name is
package="com.androidsleepmachine.gamble"
while your main activity class name is
com.AndroidSleepMachine.gamble.HOME
The ClassNotFoundException is being thrown because your Activity class name is incorrect in the manifest and isn't being found by the class loader.

It cannot find a class called:
com.AndroidSleepMachine.gamble.HOME
Why is "AndroidSleepMachine" using capital letters?
Why not just use:
android:name=".HOME"
...if your class is indeed called HOME.java? Case-sensitivity may be causing your issue.
com.AndroidSleepMachine.gamble.HOME is not the same as com.androidsleepmachine.gamble.HOME

my test application of worklight for android stopped unexpectedly when i tried to run that on AVD?

I have developed test application Using worklight for android environment. When i test that on worklight server it works fine, but when i tried to run the same on android virtual device (AVD) it throws an error message like Sorry The application Test (process com.Test) has stopped unexpectedly. Please try again. and the application terminates.
I am using Eclipse 4.2 and android version for AVD is 2.3.3

I believe the problem is because you do not have MainActivity defined in your manifest based on this logcat line:
14:55:27.034: E/AndroidRuntime(25344): Caused by:
android.content.pm.PackageManager$NameNotFoundException:
ComponentInfo{com.example.androiddemos/com.example.androiddemos.MainActivity} 01-09
You have MainActivity referenced as the parentActivityName but not defined in the manifest at all:
<activity
android:name=".ResultActivity"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".NotificationActivity" />
</activity>
If you are still using MainActivity you will need to add it to the manifest:
<activity
android:name=".MainActivity">
</activity>

it says that class is not there, but it IS there. I tried to configure things in my project's build path, but not too sure what to tweak there.
And here is how I start my Manifest file:

</intent-filter>
</activity>
Any thoughts on how to solve this, or what to look into? Thanks!

Its because you specified the "android:name" attribute in the application node in the manifest file.
Do not use the android:name attribute!
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException.
Remove it and it should work:
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:description="#string/help_text" >
This answer is taken from: java.lang.ClassNotFoundException on working app

App cannot start at all in Android 2.2 (Froyo)

My app has been running okay until the recent Froyo update. After installing the Android 2.2 SDK, I can compile my code without any errors. However, when I run it, it just force closes:
Here's the log:

The main startup class is com.handyapps.easymoney.EasyMoney. I placed a breakpoint at the start of the onCreate() method but I discovered it didn't even reach there. Somehow, the application just couldn't be loaded in Android 2.2... but it works perfectly fine for all the previous Android versions. Been trying to find the cause for the past 2 days but am totally stumped!!

I've found the solution! Just need to remove the android:name attribute from the application tag in the manifest... but the compiler should have given a warning or error.

From ClassCastException:
Thrown when a program attempts to cast
a an object to a type with which it is
not compatible.
I would go through the code and check the casts I am doing.
