Android 从 WearableListenerService 开始活动

Question

收到来自 Wear 的消息后，我在手持设备上使用 Wea​​rableListenerService 启动活动。 我尝试了所有不同类型的 Intent Flags 和其他选项，但没有一个真正起作用。我得到的只是活动应该开始的时间是一个

I/Timeline: Timeline: Activity_launch_request time:54107858 intent:Intent

我的听众（前台服务）：

public class MessageService extends WearableListenerService {

private static final int ID_SERVICE = 101;

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    Intent notiIntent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notiIntent, 0);
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    String channelId = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? createNotificationChannel(notificationManager) : "";
    Notification notification = new NotificationCompat.Builder(this, channelId)
            .setContentTitle(getString(R.string.app_name))
            .setContentText("Test")
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentIntent(pendingIntent)
            .build();

    startForeground(1, notification);

    return START_REDELIVER_INTENT;
}

@Override
public void onDestroy() {
    super.onDestroy();

}

@RequiresApi(Build.VERSION_CODES.O)
private String createNotificationChannel(NotificationManager notificationManager){
    String channelId = "my_service_channelid";
    String channelName = "My Foreground Service";
    NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
    // omitted the LED color
    channel.setImportance(NotificationManager.IMPORTANCE_NONE);
    channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
    notificationManager.createNotificationChannel(channel);
    return channelId;
}

@Override
public void onMessageReceived(MessageEvent messageEvent) {
    if (messageEvent.getPath().equals("/wear_control")) {
        Intent i = new Intent(this, MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(i);
    }
    else {
        super.onMessageReceived(messageEvent);
    }
}
}

Manifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.ronston.wearcontrol">

    tools:ignore="GoogleAppIndexingWarning">
    <activity

        android:screenOrientation="portrait"/>

    <service
        android:name=".MessageService"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" />
            <data
                android:host="*"
                android:pathPrefix="/wear_control"
                android:scheme="wear" />
        </intent-filter>
    </service>

    <activity
        android:name=".MainActivity"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

那么代码有什么问题呢？

提前致谢，抱歉代码错误...

我在这几个星期都遇到同样的问题。

最后我发现问题出在我的小米设备上。

也许你也有同样的问题……

Answer 2

尝试替换以下代码：

@Override
public void onMessageReceived(MessageEvent messageEvent) {
if (messageEvent.getPath().equals("/wear_control")) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);
}
else {
    super.onMessageReceived(messageEvent);
}

有了这个：

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);
}
