Android 8.0 及以上集成友盟推送采坑记录

setPushIntentServiceClass无效

采用mPushAgent.setPushIntentServiceClass(PushService.class)接收处理消息的方式，在友盟channel进程可以成功接收到消息，Logcat有消息日志打印，但在主进程接收不到消息

经测试，Android 8.0 及以上集成友盟推送接收及处理消息统计：

android:permission

Android 8.0 及以上务必添加权限：android:permission="android.permission.BIND_JOB_SERVICE"

<service
    android:name=".service.PushService"
    android:permission="android.permission.BIND_JOB_SERVICE"
    />

解决思路：点击进入mPushAgent.setPushIntentServiceClass(PushService.class)方法

public <U extends UmengMessageService> void setPushIntentServiceClass(Class<U> var1) {

可知参数PushService必须继承至UmengMessageService，再点击进入类UmengMessageService

public abstract class UmengMessageService extends UMJobIntentService {

public class UMJobIntentService extends JobIntentService {

public abstract class JobIntentService extends Service {

查看JobIntentService类源码发现有许多if (VERSION.SDK_INT >= 26)的判断，实际上在VERSION.SDK_INT >= 26，即Android 8.0以上采用JobScheduler机制实现服务调度，因此声明Service必须添加android:permission="android.permission.BIND_JOB_SERVICE"权限

自定义消息

如果只需接收自定义消息，并在客户端自行处理消息及构建通知栏，只需setPushIntentServiceClass，不能setMessageHandler，两者不能同时设置生效

//mPushAgent.setMessageHandler(MyUmengMessageHandler.getInstance(context));
//mPushAgent.setNotificationClickHandler(notificationClickHandler);
mPushAgent.setPushIntentServiceClass(PushService.class);

android:process

切勿设置

android:process=":push"

否则独立进程获得全局变量的值与主进程产生不同步现象

Time-out while trying to bind Service

如果发现报错：

2019-10-26 16:00:23.633 336-336/system_process W/JobServiceContext: Time-out while trying to bind 713f514 #u0a73/21000 com.lianlianpay.llterminal/.service.PushService, dropping.
2019-10-26 16:00:23.635 13259-13259/? I/yezhou: PushService.onDestroy

解决方法：注释或删除onBind方法

//@Nullable
//@Override
//public IBinder onBind(Intent intent) {
//    return null;
//}

构建通知栏

从Android 8.0开始，NotificationManager需要创建NotificationChannel，然后调用createNotificationChannel把NotificationChannel传递进去，并且通过setChannelId设置相应的id

public void buildNotification() {
    manager = (NotificationManager) mContext.getSystemService(mContext.NOTIFICATION_SERVICE);
    Notification.Builder builder = new Notification.Builder(mContext);
    //解决Android8.0收不到消息问题
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel mChannel = new NotificationChannel(PUSH_CHANNEL_ID, PUSH_CHANNEL_NAME, NotificationManager.IMPORTANCE_LOW);
        manager.createNotificationChannel(mChannel);
        builder.setChannelId(PUSH_CHANNEL_ID);
    }

    Intent intent = new Intent(mContext, ReveiveEmailActivity.class);
    Bundle bundle = new Bundle();
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pendingIntent = PendingIntent.getActivity(mContext, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    builder.setContentTitle("appblog");
    builder.setContentText("AppBlog.CN");
    builder.setDefaults(Notification.DEFAULT_ALL);
    builder.setContentIntent(pendingIntent);
    builder.setSmallIcon(R.mipmap.ic_launcher);
    builder.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_launcher));
    builder.setAutoCancel(true);

    manager.notify(id++, builder.build());
}
