如何将位图放置到Whatsapp直接通知回复中？

Question

我正在开发一个应用程序，该应用程序能够直接从notificationlistener回复Whatsapp通知，文本效果很好，但是当我发送图像时，该消息未发送，并且给我敬酒，并显示消息“无法发送空消息”信息”。你能帮我吗？

private NotificationCompat.Action replyAction(Notification notification) {
 NotificationCompat.Action action;
 for (NotificationCompat.Action action2 : new NotificationCompat.WearableExtender(notification).getActions()) {
    if (isAllowFreeFormInput(action2)) {
        return action2;
    }
 }
 if (!(notification == null || notification.actions == null)) {
     for (int i = 0; i < NotificationCompat.getActionCount(notification); i++) {
        action = NotificationCompat.getAction(notification, i);
         if (isAllowFreeFormInput(action)) {
            return action;
         }
    }
}
 return null;
}

private boolean isAllowFreeFormInput(NotificationCompat.Action action) {
if (action.getRemoteInputs() == null) {
    return false;
}
for (RemoteInput allowFreeFormInput : action.getRemoteInputs()) {
    if (allowFreeFormInput.getAllowFreeFormInput()) {
        return true;
    }
}
return false;
}

我在这里发送消息

private void sendMsg(String msg, String base64){
  RemoteInput[] allremoteInputs = new 
  RemoteInput[remoteInputs.size()];
  Intent localIntent = new Intent();
  localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  Iterator it = remoteInputs.iterator();


  String encdoedDataString = base64.replace("data:image/png;base64,","");

  byte[] decodeString = 
  Base64.decode(encdoedDataString.getBytes(), Base64.DEFAULT);
  Bitmap decodedByte = BitmapFactory.decodeByteArray(decodeString, 0, decodeString.length);
  decodedByte.prepareToDraw();


int i=0;
while (it.hasNext()) {
    allremoteInputs[i] = (RemoteInput) it.next();

    bundle.putParcelable(allremoteInputs[i].getResultKey(), decodedByte); /*my Bitmap*/
    //bundle.putCharSequence(allremoteInputs[i].getResultKey(), msg);//This work, apart from Hangouts as probably they need additional parameter (notification_tag?)

    i++;
}

RemoteInput.addResultsToIntent(allremoteInputs, localIntent, bundle);

try {
    Objects.requireNonNull(replyAction(notification)).actionIntent.send(this, 0, localIntent);
} catch (PendingIntent.CanceledException e) {
    Log.e(Const.LOG, "replyToLastNotification error: " + e.getLocalizedMessage());
}  
}
