Wear app打开从磨损通知打开的多个活动

Question

我已经通过pIntent为我的磨损应用创建了一个通知。因此，当我单击通知上的打开按钮时，应用程序将打开一个新活动，而不是已经运行的活动。我在清单中有singleTask。我也尝试在手机上这样做，然后它完美无缺。

这是我的穿着清单：

    <uses-permission android:name="android.permission.VIBRATE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:launchMode="singleTask"
        android:supportsRtl="true"
        android:theme="@android:style/Theme.DeviceDefault">
        <uses-library
            android:name="com.google.android.wearable"
            android:required="false" />

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".timer"
            android:label="@string/title_activity_timer"
            android:launchMode="singleTask"
            ></activity>
    </application>

</manifest>

这是我的磨损java文件代码：

intent = new Intent(timer.this, timer.class);
                pIntent = PendingIntent.getActivity(timer.this, 0, intent, 0);

                notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                notification = new Notification.Builder(timer.this)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentIntent(pIntent)
                        .setContentTitle("Interval Training Timer")
                        .setPriority(Notification.PRIORITY_HIGH)
                        .setContentText("WORK" +  " - " + "Time remaining: " + minutescountdown + ":" + secondscountdown)
                        .build();
                notificationManager.notify(0,notification);

            notification.flags = Notification.FLAG_AUTO_CANCEL;
            notificationManager.notify(0, notification);
