Gear SDK SAFileTransfer FILE_IO错误

我试图使用Samsung Mobile SDK将文件从Android主机发送到Samsung Gear设备，无论我如何尝试，始终会出现FILE_IO错误。

我正在尝试所有可用的权限（双方）。

有人可以给我任何提示吗？

Android方面：

String filename = "file:///storage/emulated/0/Download/TestRecipe2-25.zip"; 
if (mGuruAgentService != null) mGuruAgentService.sendFile(filename);

public int sendFile(String fileName) {
  if (mFileTransfer == null)
    registerForFileTransfer();
  if (mFileTransfer != null) {


  try {
    Log.i(TAG, "Sending file " + fileName);
    tx = mFileTransfer.send(mPeerAgent, fileName);
    return tx;
  } catch (Exception e)
  {
  Log.i(TAG, "Cannot send file" + e.getMessage());
  }

}
return 0;
}

侧面：

function fileReceiveInt() {
var newFilePath = "downloads/file.zip";

var receivefilecallback =
{
onreceive: function(transferId, fileName)
{
console.log("Incoming file transfer request form the remote peer agent. transferId: " + transferId + " file name : " + fileName);

try {
gFileTransfer.receiveFile(transferId, newFilePath);
} catch(e) {
console.log("Error Exception, error name : " + e.name + ", error message : " + e.message);
}
},
onprogress: function(transferId, progress)
{
console.log("onprogress transferId: " + transferId + ", progress : " + progress);
},
oncomplete: function(transferId, localPath)
{
console.log("File transfer complete. transferId: " + transferId);
},
onerror: function(errorCode, transferId)
{
console.log("FileReceiveError transferId: " + transferId + " code : " + errorCode);
}
}


try {
console.log('setting recieve interface');
gFileTransfer = SAAgent.getSAFileTransfer();
gFileTransfer.setFileReceiveListener(receivefilecallback);

} catch (err) {
console.log('getSAFileTransfer exception <' + err.name + '> : ' + err.message);

}
}

我将始终以FILE_IO错误的形式获取onError :(我正在测试gFileTransfer.receiveFile（transferId，“”）;以获取默认路径，以及File：/// opt / usr / media / Downloads ...
