我对this one提出了一个非常类似的问题。当用户收到推送通知时，我希望他们能够点击它以打开我的应用中的页面。这是我目前无法使用的代码。
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, ActivityPersonalRewardsGfits.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
目前，会生成消息并调用此方法，但它不会打开我的ActivityPersonalRewardsGfits类。不，这不是一个错字，程序员实际拼写这样的礼物。
如何让我的应用程序打开该课程？
编辑： 我的通知启动应用程序，但随后抛出此错误：

答案 0 :(得分：2)
您的ActivityPersonalRewardsGfits活动缺少
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
我无权访问您的代码部分，但我猜您可能也没有使用正确的上下文。所以为了以防万一，我会替换
Intent notificationIntent = new Intent(context, ActivityPersonalRewardsGfits.class);
用这个：
Intent notificationIntent = new Intent().setClassName("com.appname", "com.appname.ActivityPersonalRewardsGfits");
答案 1 :(得分：0)
您的代码看起来是正确的。该方法与在我的应用程序中工作的代码相同。因此，我看到了错误的两种可能性：
活动无法启动。确保在应用程序清单中，活动意图过滤器具有以下内容：
<category android:name="android.intent.category.LAUNCHER" />
广播接收器未执行。您发布的代码看起来是广播接收器的代码。你确认它确实在执行吗？如果不是，可能的原因是：
（a）您尚未正确注册来自GCM的推送通知广播事件。
（b）您的申请流程未激活。从Android 3.x开始，当应用程序订阅的广播被发送时，应用程序不会自动启动。尝试手动启动应用程序（以便该过程变为活动状态）。如果这是问题，则有解决方法。
