Question

我正在研究android中的firebase推送通知，我已经成功实现了，一切运行良好，我正在推送按钮上的特定活动，它工作但只有当我的应用程序在后台运行时，当应用程序关闭时（不在后台）然后点击推送从第一个活动（主要活动）启动应用程序。我搜索了很多链接没有运气，所以任何伙伴都可以帮我解决，我在这里发布我的代码。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";
    public static String PUSH_NOTIFICATION = "PUSH_NOTIFICATION";
    String store_id, img_url;
    String store_name;
    String headline;
    String store_img;
    int size = 200;
    String subtext;

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        size = (int) Math.ceil(Math.sqrt(300 * 200));
        Message message = new Message();
        message.obj = remoteMessage;
        handler.sendMessage(message);
        Intent pushNotification = new Intent(this.PUSH_NOTIFICATION);
        LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
    }


    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
// TODO(developer): Handle FCM messages here.
            Log.d(TAG, "=====push msg------by jigar--" + msg.toString());
            final RemoteMessage remoteMessage = (RemoteMessage) msg.obj;
            if (remoteMessage.getData().size() > 0) {
                Log.d(TAG, "Message data payload: " + remoteMessage.getData());
                final JSONObject jsonObject;
                try {
                    jsonObject = new JSONObject(remoteMessage.getData().toString());
                    Log.d(TAG, "tag: " + jsonObject.getString("store_id"));
                    Log.d(TAG, "message: " + jsonObject.getString("img_url"));
                    store_id = jsonObject.getString("store_id");
                    img_url = jsonObject.getString("img_url");
                    headline = jsonObject.getString("headline");
                    store_name = jsonObject.getString("store_name");
                    store_img = jsonObject.getString("store_image");
                } catch (JSONException e) {
                    e.printStackTrace();
                }
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {

                    Glide.with(getApplicationContext())
                            .load(img_url)
                            .asBitmap()
                            .into(new SimpleTarget<Bitmap>() {
                                @Override

Answer 1

请在AndroidManifest.xml文件的MainActivity标记中添加以下属性。

android:launchMode="singleTask"

Answer 2

使用以下代码，我可以打开我的MainActivity。

NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, MainActivity.class);

    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;
    notificationManager.notify(0, notification);

如何关闭推送通知，同时关闭应用程序（甚至不在后台）
