Starting an alarm manager application on reboot

Presently, I am working on app that sets the phone into the vibration mode or the ringer mode at the selected time. I have successfully implemented this using the alarmmanager in my application.
I want my app to remember all the pending intents when the phone is rebooted.
I found a sample code in the internet, but it seems to crash my app when the phone is rebooted. I don't know what's going wrong.
Here is alarmreciever.java
package ishan.khandelwal.vitsilentmode;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.widget.Toast;
public class AlarmReciever extends BroadcastReceiver
{
private AudioManager mAudioManager;
#Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent("ishan.khandelwal.vitsilentmode");
context.startService(serviceIntent);
}
mAudioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
// Show the toast
Toast.makeText(context, "Vibration Mode", Toast.LENGTH_SHORT).show();
}
}

Thanks for the help in advance.

Ok, the problem is that you have specified in your AndroidManifest the wrong/a nonexistent receiver implementation. You specified this:
<receiver
android:name=".receiver.StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
The problem is you have no class called StartMyServiceAtBootReceiver. What you I think you should have is something like this:
<receiver
android:name=".AlarmReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>

Why does my manifest.xml keep deleting the changes I make when I put the program into an apk

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

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.

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

Android ClassNotFoundException on published app

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:

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.

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:

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.
