在开发者控制台中，我收到一些有关以下异常的错误报告：

java.lang.RuntimeException: Unable to instantiate receiver com.cypressworks.changelogviewer.InstallReciever: java.lang.ClassNotFoundException: com.cypressworks.changelogviewer.InstallReciever in loader dalvik.system.PathClassLoader[/mnt/asec/com.cypressworks.changelogviewer-1/pkg.apk]

用户添加了消息，当他在市场上更新应用程序时发生此错误。

我自己从未经历过这个例外，尽管我猜测原因。接收方收听android.intent.action.PACKAGE_REPLACE和android.intent.action.PACKAGE_ADDED。当应用程序本身更新时，广播将被发送到接收方，但在它接收时，它已被删除。

我的猜测是否合理以及如何避免此错误？

这是清单条目：

        <receiver
            android:name=".InstallReciever"
            android:exported="false"
            android:enabled="true">
            <intent-filter>
                <action
                    android:name="android.intent.action.PACKAGE_REPLACED" />
                <action
                    android:name="android.intent.action.PACKAGE_ADDED" />
                <data
                    android:scheme="package" />
            </intent-filter>
        </receiver>

以下是代码：

public class InstallReciever extends BroadcastReceiver {

    @Override
    public void onReceive(final Context c, final Intent intent) {
        final SharedPreferences prefs = PreferenceManager
                .getDefaultSharedPreferences(c);

        //Checking some preferences...

        //Creating a notification

        final String ns = Context.NOTIFICATION_SERVICE;
        final NotificationManager mNotificationManager = (NotificationManager) c
                .getSystemService(ns);

        final int icon = R.drawable.icon;
        final CharSequence tickerText = c.getString(R.string.notification_text);
        final long when = System.currentTimeMillis();

        final Notification notification = new Notification(icon, tickerText,
                when);

        final CharSequence contentText = c.getString(R.string.app_name);

        final Intent notificationIntent = new Intent(c,
                ChangeListActivity.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP
                | Intent.FLAG_ACTIVITY_NEW_TASK);

        final PendingIntent contentIntent = PendingIntent.getActivity(c, 0,
                notificationIntent, 0);

        notification.setLatestEventInfo(c, tickerText, contentText,
                contentIntent);

        mNotificationManager.notify(0, notification);
    }

}

错误报告java.lang.ClassNotFoundException
