Android 未从通知中启动PendingEvent

我已经尝试了大约20种不同的答案，但没有一种是有效的

只是想从我的通知中启动一个活动。它不起作用了。它没有做任何事情，如果我进入我的主屏幕并点击它，它甚至不会打开应用程序

我从一开始就添加了很多东西，所以对于所有可能不需要的东西感到抱歉。我只是一直在寻找答案

private void sendNotification(String msg, String cont, String title) {
    mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    //        this.getSystemService(Context.NOTIFICATION_SERVICE);
Log.d("msg",msg);

int requestID = (int) System.currentTimeMillis();
Intent notificationIntent = new Intent(getApplicationContext(), WalkerRequest.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Log.d("Intent","setting content intent");
PendingIntent contentIntent = PendingIntent.getActivity(this, requestID, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT
        | PendingIntent.FLAG_ONE_SHOT);

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.paw_icon)
                .setContentTitle(title)
                .setStyle(new NotificationCompat.BigTextStyle()
                        .bigText(cont))
                .setContentText(cont);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

这是完整的类，它是从谷歌直接几乎

public class GcmIntentService extends IntentService {
    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    NotificationCompat.Builder builder;

    public GcmIntentService() {
        super("GcmIntentService");
    }
    public static final String TAG = "GCM Demo";

    @Override
    protected void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that GCM will be
             * extended in the future with new message types, just ignore any message types you're
             * not interested in, or that you don't recognize.
             */
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
                sendNotification("Send error: ", extras.toString(), "Nada");
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
                sendNotification("Deleted messages on server: ", extras.toString(), "nada");
                // If it's a regular GCM message, do some work.
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
                // This loop represents the service doing some work.
                for (int i = 0; i < 5; i++) {
                    Log.i(TAG, "Working... " + (i + 1)
                            + "/5 @ " + SystemClock.elapsedRealtime());
                    try {
                        Thread.sleep(500);
                    } catch (InterruptedException e) {
                    }
                }
                String cont = intent.getExtras().getString("message");
                String title = intent.getExtras().getString("title");

                Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
                // Post notification of received message.
                sendNotification("Received: ", cont, title);
                Log.i(TAG, "Received: " + extras.toString());
            }
        }
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }

    // Put the message into a notification and post it.
    // This is just one simple example of what you might choose to do with
    // a GCM message.

    private void sendNotification(String msg, String cont, String title) {
        mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
        //        this.getSystemService(Context.NOTIFICATION_SERVICE);

        Log.d("msg",msg);

        int requestID = (int) System.currentTimeMillis();
        Intent notificationIntent = new Intent(getApplicationContext(), WalkerRequest.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        Log.d("Intent","setting content intent");
        PendingIntent contentIntent = PendingIntent.getActivity(getBaseContext(), requestID, notificationIntent, PendingIntent.FLAG_ONE_SHOT);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.paw_icon)
                        .setContentTitle(title)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(cont))
                        .setContentText(cont);
        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }
}

尝试以下操作：

public void createNotification（）{
试一试{
Intent pnIntent=newintent（这是newActivity.class）；
pnIntent.putExtra（“通知ID”，通知ID）；
PendingEvent PendingEvent=PendingEvent.getActivity（this，01，pnIntent，Intent.FLAG_ACTIVITY_CLEAR_TASK）；
NotificationCompat.Builder=新建NotificationCompat.Builder（getApplicationContext（））；
builder.setContentTitle（getString（R.string.app_name））；
setContentText（getString（R.string.running））；
builder.setContentIntent（挂起内容）；
builder.setSmallIcon（R.drawable.ic_stat_永久通知）；
builder.setAutoCancel（false）；
builder.setcongressing（true）；
设置优先级（1）；
通知通知=builder.build（）；
final NotificationManager NotificationManager=（NotificationManager）getSystemService（Context.NOTIFICATION\u服务）；
NotificationManager.notify（永久通知ID，通知）；
}捕获（例外e）{
Log.e（“UnityApplication”，“创建通知时出错”，e）；
}
}

当应用程序未处于活动状态时，

getApplicationContext（）

将不可用，因此最好使用该服务的

上下文

我的建议是通过这些方法尽可能追溯到接收推送通知意图的位置，并更改传递给
onReceive（）
方法的任何上下文，并将其替换为
getApplicationContext（）
使用
context
，然后可以在方法中使用context参数。
Try而不是.getActivity（这，…Try.getActivity）（getBaseContext，…是的，我以前也有过，对我不起作用这方面有很多错误…例如Intent.FLAG\u ACTIVITY\u CLEAR\u任务有一个错误，基本上说我不能使用这个选项嘿，很遗憾我不明白你在说什么，能提供一些示例代码吗？抱歉！我正在用完整的c语言编辑帖子类的ode您可以发布您的服务代码吗？我将建议您更改什么添加该类的其余部分和接收类更改此Intent notificationIntent=new Intent（getApplicationContext（），WalkerRequest.class）；更改为Intent notificationIntent=new Intent（this，WalkerRequest.class）；
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}
