Question

我正在尝试将附加内容中的一些数据从gcm服务发送到我的活动，但该捆绑包将变为空。我尝试过使用Bundle extra和intent extras方法，并尝试在onCreate和onNewIntent方法中接收它们。由于某种原因，它没有收到。

以下是我的GcmService中的代码： -

        Intent intent = new Intent(this, ChatActivity.class);
        Bundle bundle = new Bundle();
        bundle.putInt(AppConstants.KEY_RESERVATION_ID, 0);
        bundle.putString(AppConstants.KEY_HOST_OR_CONCIERGE_ID, fromId);
        bundle.putInt(AppConstants.KEY_HOST_TYPE, MessageThreadDao.TYPE_HOST);

        intent.putExtra(AppConstants.KEY_RESERVATION_ID, 0);
        intent.putExtra(AppConstants.KEY_HOST_OR_CONCIERGE_ID, fromId);
        intent.putExtra(AppConstants.KEY_HOST_TYPE, MessageThreadDao.TYPE_HOST);
        intent.putExtras(bundle);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        String soundPref = Utility.getStringSharedPreference(this, AppConstants.PREFS_SOUND);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher)).setAutoCancel(true)
                .setContentTitle(getString(R.string.rental_notification)).setContentText(msg);

        if (soundPref.equals("1"))
            mBuilder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);
        else {
            mBuilder.setSound(Uri.parse(""));
        }

        //        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        //            mBuilder.setColor(getResources().getColor(R.color.header_blue));
        //        }
        mBuilder.setContentIntent(contentIntent);

        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

以下是我的活动中的代码： -

//In onCreate
        mReservationId = getIntent().getExtras().getInt(AppConstants.KEY_RESERVATION_ID, 0);
            mHostOrConciergerId = getIntent().getExtras().getInt(AppConstants.KEY_HOST_OR_CONCIERGE_ID, 0);
            mHostType = getIntent().getExtras().getInt(AppConstants.KEY_HOST_TYPE, 0);

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        try {
        if (intent.getExtras() != null) {

            mReservationId = intent.getExtras().getInt(AppConstants.KEY_RESERVATION_ID, 0);
            mHostOrConciergerId = intent.getExtras().getInt(AppConstants.KEY_HOST_OR_CONCIERGE_ID, 0);
            mHostType = intent.getExtras().getInt(AppConstants.KEY_HOST_TYPE, 0);
        }
        retrieveChatHistoryFromDB();

    } catch (Exception ignore) {
    }
}

Android Manifest中的

： -

 <activity
            android:name=".activity.ChatActivity"
            android:label="@string/messages"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustResize|stateAlwaysHidden" />

我也没有设置任何标志。只是一个简单的意图，仍然没有收到数据。

Answer 1

您可以从GCM服务类

中删除此代码

 Bundle bundle = new Bundle();
        bundle.putInt(AppConstants.KEY_RESERVATION_ID, 0);
        bundle.putString(AppConstants.KEY_HOST_OR_CONCIERGE_ID, fromId);
        bundle.putInt(AppConstants.KEY_HOST_TYPE, MessageThreadDao.TYPE_HOST);

 intent.putExtras(bundle);

Answer 2

尝试更改活动manifest.xml的启动模式

android:launchMode="singleTop"

Answer 3

从代码中删除以下行

intent.putExtra(AppConstants.KEY_RESERVATION_ID, 0);
intent.putExtra(AppConstants.KEY_HOST_OR_CONCIERGE_ID, fromId);
intent.putExtra(AppConstants.KEY_HOST_TYPE, MessageThreadDao.TYPE_HOST);

应该是这样的

Intent intent = new Intent(this, ChatActivity.class);
Bundle bundle = new Bundle();
bundle.putInt(AppConstants.KEY_RESERVATION_ID, 0);
bundle.putString(AppConstants.KEY_HOST_OR_CONCIERGE_ID, fromId);
bundle.putInt(AppConstants.KEY_HOST_TYPE, MessageThreadDao.TYPE_HOST);
intent.putExtras(bundle);

您想要在NewNetent（）上接收的活动应该有

android:launchMode="singleTop"

或添加标志t0 intent

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                    Intent.FLAG_ACTIVITY_SINGLE_TOP);

捆绑数据未在GCM的活动中接收
