我试图用GCM向手机发送推送通知,它在
Android 4的设备上工作正常,但当我尝试在Android 2.3上发送通知应用程序崩溃,我收到此错误

这是我的GCMBaseIntentService类
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCMIntentService";
PendingIntent contentIntent;

}
private void generateNotification(Context context,String message,String title) {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.icon = R.drawable.ic_launcher;
notification.tickerText = "i-Asigutare";
notification.defaults = Notification.DEFAULT_ALL;
notification.setLatestEventInfo(context,title,message,null);
notificationManager.notify(0,notification);
}
}
解决方法
问题是关于notification.setLatestEventInfo方法.
该方法在API级别11中为deprecated,鼓励使用Notification.Builder.您还可以查看NotificationCompat.Builder以了解支持库的用法.
如果你仍然想按照自己的方式行事,你应该看看这个问题的接受答案：
Android – notification manager,having a notification without an intent
这清楚地表明使用这样的
notification.setLatestEventInfo(context,contentTitle,contentText,PendingIntent.getActivity(getApplicationContext(),new Intent(),0));
