I have an application thats been published awhile on Google play, I have been fixing reported bugs as they come in but recently this log below came in and I don't know what to make of it:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.mammothtooth.flightinfo/com.mammothtooth.flightinfo.ui.SplashActivity}: java.lang.ClassNotFoundException: com.mammothtooth.flightinfo.ui.SplashActivity in loader dalvik.system.PathClassLoader[/system/framework/com.google.android.maps.jar:/mnt/asec/com.mammothtooth.flightinfo-1/pkg.apk]

Does anyone know anything about this type of error log? My SplashScreenActivity is there and its defined as the entry point of the application in the manifest as follows:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/Theme.Sherlock" >
<uses-library android:name="com.google.android.maps" />
<activity
android:label="#string/app_name"
android:name=".ui.SplashActivity"
android:theme="#android:style/Theme.NoTitleBar"
android:configChanges="keyboard|keyboardHidden|orientation"
android:screenOrientation="portrait">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Would the placing of the uses-library be an issue in the manifest?
I can't reproduce this issue on any of my android devices so any help is greatly appreciated in locating what might be the cause of this issue.

I'm Naive in Android development. I tried to use flow/mortar for development and stuck with an exception.
Here's what I did. In Eclipse, I chose New (Crtl N) -> Android Project from existing code and imported the flow sample downloaded from the square flow website https://github.com/square/flow/.
Eclipse marked errors in all the files as the package name was not matching the file's location. So to fix the package mismatch issue, I moved the files from : \flow-master\flow-sample\src\main\java\com\example\flow to : \flow-master\flow-sample\src\com\example\flow.
After this, I got some more errors saying 'Unresolved to a Type' which I fixed by importing proper jar files. Now all the errors are cleared and I tried to install and launch the app.
The app crashes as soon as we launch with the Logcat error below:
E/AndroidRuntime(5438): FATAL EXCEPTION: main
E/AndroidRuntime(5438): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.flow/com.example.flow.MainActivity}: java.lang.ClassNotFoundException: com.example.flow.MainActivity

The error says that the file MainActivity is not found even when the file is available in the path com.example.flow.. Can someone please help me understand what the issue is?

EDIT: STILL NEED HELP >:( Logcat added, as well as the manifest fix I can use for emulators only but not physical devices. If I transfer file to APK and load onto my device the manifest.xml file for that project just reverts to the second copy of the manifest.xml file.
I had this code working literally 5 minutes ago where the whole app would run a welcome screen, 6 different "flash cards", and an exit screen with button transitions. Now all of a sudden if I push any button the app crashes. Just says app has stopped working unexpectedly. I would put the logcat, but the error message is always dealing with the activity missing in the manifest. I am getting frustrated and just want to sleep.
logcat I get for the bottom manifest file that it always goes to. If it manually add the others then I do not get it. DOES NOT WORK WHEN TURNING PROJECT INTO APK FORMAT

LOGCAT JUST SAYS ACTIVITY NOT FOUND DECLARE IN MANIFEST
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

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:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="business.premium"
android:versionCode="1"

<application

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</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
Can someone please tell me how to fix my problem? I'm building my first android app and below is the error codes I get when application is launched in Emulator.
Thank you

The cause of your problem is:
java.lang.ClassNotFoundException: obd.gss.namespace.activity.Gssobdreadermainactivity
Did you forget to add your Activity to your manifest?
Your Manifest should look something like:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="obd.gss.namespace"
android:versionCode="1"
android:versionName="1.0" >
<!-- permissions and other stuff here -->
<application
android:icon="#drawable/icon"
android:label="#string/app_name">
<activity android:name=".activity.Gssobdreadermainactivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!--more activities and services here -->
</application>
</manifest>
Note that the combination of the manifest tag's package attribute and the activity tag's name attribute should be exactly the same as the fully qualified name of your class. Using my above example, you would wind up with:
obd.gss.namespace.activity.Gssobdreadermainactivity
I've had a similar issue, particularly with newly imported projects. The closest thing to a solution I've found is to make sure the .classpath file is writable, restart Eclipse(or whichever IDE you use), refresh the project, clean and build the project and try again. This doesn't always fix it, but doing it a couple times usually makes the error go away for me. The essence of the error is that the Android OS can't find the Activity, although it does know that the Activity should exist and is trying to launch it.
What does your source tree look like? You probably need to remove the .activity. and .Activity. prefixes from your applications fully quallified class name. Unless, of course, you have an "activity" and an "Activity" folder in your source tree (=
