您可以通过发送通知向您的应用推送通知,以便用户与火基地互动,当您的应用关闭时,根据一些参数转到火基地。
确保在执行此操作之前先将您的项目添加到 Fire base 中:否则将您的项目添加到 fire base 中,并在您的项目的 app 文件夹中使用包名、指纹和 google_services.json 文件。
Fire base Cloud Messaging
它会将通知推送到您的应用程序,如果它关闭则它让用户通过按下通知打开应用程序,如果您想向用户显示通知以定向到同一帐户的另一个应用程序,当应用程序将使用这两种代码:
为您创建一流的MyFirebaseMessagingService
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String NOTIFICATION_ID_EXTRA = "notificationId";
private static final String IMAGE_URL_EXTRA = "imageUrl";
private static final String ADMIN_CHANNEL_ID ="admin_channel";
private NotificationManager notificationManager;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getData().size()>0){
Intent notificationIntent = new Intent(Intent.ACTION_VIEW);
notificationIntent.setData(Uri.parse(remoteMessage.getData().get("applink")));
PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
final PendingIntent pendingIntent = PendingIntent.getActivity(this,
0 /* Request code */, notificationIntent,
PendingIntent.FLAG_ONE_SHOT);
int notificationId = new Random().nextInt(60000);
Bitmap bitmap = getBitmapfromUrl(remoteMessage.getData().get("imageurl"));
Intent likeIntent = new Intent(this,LikeService.class);
likeIntent.putExtra(NOTIFICATION_ID_EXTRA,notificationId);
likeIntent.putExtra(IMAGE_URL_EXTRA,remoteMessage.getData().get("message"));
PendingIntent likePendingIntent = PendingIntent.getService(this,
notificationId+1,likeIntent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
setupChannels();
}
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, ADMIN_CHANNEL_ID)
.setLargeIcon(bitmap)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(remoteMessage.getData().get("title"))
.setStyle(new NotificationCompat.BigPictureStyle()
.setSummaryText(remoteMessage.getData().get("message"))
.bigPicture(bitmap))/*Notification with Image*/
.setContentText(remoteMessage.getData().get("message"))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.addAction(R.drawable.icon,
getString(R.string.notification_add_to_cart_button),likePendingIntent)
.setContentIntent(pendingIntent);
notificationManager.notify(notificationId, notificationBuilder.build());
}
}
@RequiresApi(api = Build.VERSION_CODES.O)
private void setupChannels(){
CharSequence adminChannelName = getString(R.string.notifications_admin_channel_name);
String adminChannelDescription = getString(R.string.notifications_admin_channel_description);
NotificationChannel adminChannel;
adminChannel = new NotificationChannel(ADMIN_CHANNEL_ID, adminChannelName, NotificationManager.IMPORTANCE_LOW);
adminChannel.setDescription(adminChannelDescription);
adminChannel.enableLights(true);
adminChannel.setLightColor(Color.RED);
adminChannel.enableVibration(true);
if (notificationManager != null) {
notificationManager.createNotificationChannel(adminChannel);
}
}
public Bitmap getBitmapfromUrl(String imageUrl) {
try {
URL url = new URL(imageUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
return BitmapFactory.decodeStream(input);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
再创建一个类FirebaseIDService来获取fire base的实例id服务
public class FirebaseIDService extends FirebaseInstanceIdService {
public static final String FIREBASE_TOKEN = "firebase token";
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
SharedPreferences preferences =
PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
preferences.edit().putString(FIREBASE_TOKEN, refreshedToken).apply();
}
制作类名LikeService
public class LikeService extends Service {
private static final String NOTIFICATION_ID_EXTRA = "notificationId";
private static final String IMAGE_URL_EXTRA = "imageUrl";
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
要使用 Firebase 在 Oreo 上支持通知,请不要忘记创建频道,并且此频道会在 您的第一个启动器活动中初始化。
在您的项目的第一个启动器活动的 oncreate 中包括这些渠道;
String channelId = "1";
String channel2 = "2";
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(channelId,
"Channel 1", NotificationManager.IMPORTANCE_HIGH);
notificationChannel.setDescription("This is BNT");
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setShowBadge(true);
notificationManager.createNotificationChannel(notificationChannel);
NotificationChannel notificationChannel2 = new NotificationChannel(channel2,
"Channel 2",NotificationManager.IMPORTANCE_MIN);
notificationChannel.setDescription("This is bTV");
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setShowBadge(true);
notificationManager.createNotificationChannel(notificationChannel2);
}
现在您必须将您的 Firebase 服务类放在 Mainfest 应用程序标签下:
<service android:name=".activities.services.MyFirebaseMessagingService"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
<action android:name="com.google.android.c2dm.intent.RECEIVE"/>
</intent-filter>
</service>
<service android:name=".activities.services.FirebaseIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
现在在您的设备上运行您的应用程序,然后使用 fire base 推送通知,确保您的代码已正确集成,然后运行 app: 并转到 fire base 云消息传递:
根据您的应用将数据放入照片中:关闭时:
如果您的应用正在使用中,那么您的预先写入数据选项将显示,其有关您的同一帐户的促销应用的数据,请不要在此处使用其他帐户应用,
确保您的密钥应与上述类中的 onMessagede 在 MyFirebaseMessagingService 类中收到的一样
