Android-8.0新特性-通知通道配置

Android 8.0开始发送通知需要配置渠道id；

Application#onCreate()中配置

//8.0
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    // 通知渠道的id
    String id = "你的渠道id";
    // 用户可以看到的通知渠道的名字.
    CharSequence name = getString(R.string.app_name);
    // 用户可以看到的通知渠道的描述
    String description = getString(R.string.app_push_message_hint);
    int importance = NotificationManager.IMPORTANCE_HIGH;
    NotificationChannel mChannel = new NotificationChannel(id, name, importance);
    mChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
    // 配置通知渠道的属性
    mChannel.setDescription(description);
    // 设置通知出现时的闪灯（如果 android 设备支持的话）
    mChannel.enableLights(true);
    mChannel.setLightColor(Color.RED);
    mChannel.setSound(Uri.parse("android.resource://" + BaseUtil.getPackageInfo(BaseUtil.getApp()).packageName + "/" + R.raw.hint_zz_four), null);
    // 设置通知出现时的震动（如果 android 设备支持的话）
    mChannel.enableVibration(true);
    mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
    //最后在notificationmanager中创建该通知渠道
    if (mNotificationManager != null) {
        mNotificationManager.createNotificationChannel(mChannel);
    }
}

发送通知

//发送通知则需要使用渠道id
Intent it = new Intent(context, MemoListActivity.class);
PendingIntent pi = PendingIntent.getActivity(context, 0, it, PendingIntent.FLAG_CANCEL_CURRENT);
Resources res = context.getResources();
Bitmap bmp = BitmapFactory.decodeResource(res, R.mipmap.ic_launcher);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
//定义notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "你的渠道id");
builder.setContentTitle("备忘录通知")
    .setSmallIcon(R.mipmap.ic_launcher)
    .setLargeIcon(bmp)
    .setContentText(content + "")
    .setTicker("备忘录通知")
    .setSound(Uri.parse("android.resource://您的包名/" + R.raw.hint))
    .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
    // 单机 面板自动取消通知
    .setAutoCancel(true)
    .setContentIntent(pi);

if (notificationManager != null) {
    notificationManager.notify(1, builder.build());// 通过管理器发送通知（通知的id，Notification对象）
}
