Android Broadcast Receiver Error: Class not found exception

Question

I have a Broadcast receiver setup so that a pop-up message is displayed to the user after each upgrade of my app, or if this is the first time the package is installed. I tested this on my Droid running Android 2.2 both as a fresh install and after upgrading my app, as well in the Emulator running 1.5 and 1.6, and I see everything run fine.

However, I received an error report from a user that lists the following exception:

java.lang.RuntimeException: Unable to instantiate receiver 
com.name.pkg.FirstRunBroadcastReceiver: java.lang.ClassNotFoundException: com.name.pkg.app_name.FirstRunBroadcastReceiver in loader dalvik.system.PathClassLoader[/data/app/com.name.pkg.app_name.apk]

Can someone tell me why one of my users received this exception?

In my Manifest file, I have things setup like this:

<receiver android:name=".FirstRunBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_REPLACE"/>
        <data android:scheme="package" android:path="com.name.pkg.app_name">
    </intent-filter>
</receiver>

The class FirstRunBroadcastReceiver is setup like this:

package com.name.pkg.app_name;

public class FirstRunBroadcastReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Contenxt context, Intent intent)
    {
        Uri uri = intent.getData();
        if( uri.toString().compareTo("package:com.name.pkg.app_name") == 0 )
        {
            //set shared prefs data to determine if start-up message should be shown
        }
    }
}

Upon a first time install, the default value for the shared prefs is set so that the pop-up message will be displayed, but I wouldn't think that would have anything to do with this exception.

I tested it again, and I don't receive an exception. Thanks for any help you can provide.

Is package declaration in your FirstRunBroadcastReceiver class as follows?

package com.name.pkg.app_name;

According to your exception stack it should be so.
