Upload and Retrieve the Temporary File - Android

This guide demonstrates how to upload and retrieve files from VideoSDK's temporary file storage system.

uploadBase64File()

• By using the uploadBase64File() method of the Meeting class, you can upload your file to Videosdk's Temporary storage.

• The uploadBase64File() method only works with base64. Therefore, it is necessary to convert your file into base64 format.

• You have to pass base64Data,token,fileName and implementation of TaskCompletionListener as parameter in uploadBase64File() method.

• When the upload is complete, the onComplete() method of TaskCompletionListener will provide the corresponding fileUrl, which can be used to retrieve the uploaded file.

• If an error occurs during the upload process, the onError() method of TaskCompletionListener will provide the error details.

Kotlin

private fun uploadFile() {
  val base64Data = "<Your File's base64>" // Convert your file to base64 and pass here
  val token = "<VIDEOSDK_TOKEN>"
  val fileName = "myImage.jpeg" // Provide name with extension here
  meeting!!.uploadBase64File(
    base64Data,
    token,
    fileName,
    object : TaskCompletionListener<String?, String?> {
      override fun onComplete(data: String?) {
          Log.d("VideoSDK", "Uploaded file url: $data")
      }

      override fun onError(error: String?) {
          Log.d("VideoSDK", "Error in upload file: $error")
      }
    }
  )
}

Java

private void uploadFile() {
  String base64Data = "<Your File's base64>"; // Convert your file to base64 and pass here
  String token = "<VIDEOSDK_TOKEN>";
  String fileName = "myImage.jpeg"; // Provide name with extension here
  meeting.uploadBase64File(base64Data, token, fileName, new TaskCompletionListener<String, String>() {
    @Override
    public void onComplete(@Nullable String data) {
        Log.d("VideoSDK", "Uploaded file url: " + data);
    }

    @Override
    public void onError(@Nullable String error) {
        Log.d("VideoSDK", "Error in upload file: " + error);
    }
  });
}

fetchBase64File()

• By using the fetchBase64File() method of the Meeting class, you can retrieve your file from Videosdk's Temporary storage.

• To retrieve a file, you need to pass the fileUrl (which is returned by the uploadBase64File() method), the token, and an implementation of the TaskCompletionListener as parameters.

• When the fetch operation is complete, the onComplete() method of TaskCompletionListener will provide the file in base64 format.

• If an error occurs during the fetch operation, the onError() method of TaskCompletionListener will provide the error details.

Kotlin

private fun fetchFile() {
  val url = "<Your FileUrl>"  // Provide fileUrl which is returned by uploadBase64File()
  val token = "<VIDEOSDK_TOKEN>"
  meeting.fetchBase64File(url, token, object : TaskCompletionListener<String?, String?> {
      override fun onComplete(data: String?) {
          Log.d("VideoSDK", "Fetched file in base64:$data")
      }

      override fun onError(error: String?) {
          Log.d("VideoSDK", "Error in fetch file: $error")
      }
  })
}

Java

private void fetchFile() {
  String url = "<Your FileUrl>";  // Provide fileUrl which is returned by uploadBase64File()
  String token = "<VIDEOSDK_TOKEN>";
  meeting.fetchBase64File(url, token, new TaskCompletionListener<String, String>() {
      @Override
      public void onComplete(@Nullable String data) {
          Log.d("VideoSDK", "Fetched file in base64:" + data);
      }

      @Override
      public void onError(@Nullable String error) {
          Log.d("VideoSDK", "Error in fetch file: " + error);
      }
  });
}

note

The file stored in the system will be automatically deleted once the current room/meeting comes to an end.
