Android – cannot resolve base64.encodetostring

I'm trying to save an image on firebase using the following code

  Bitmap bm = BitmapFactory.decodeFile(imgDecodableString);
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  bm.compress(Bitmap.CompressFormat.JPEG,100,baos);
  byte[] byteArray =  baos.toByteArray();
  String encodedImage = Base64.encodeToString(byteArray,Base64.DEFAULT);

But I face a mistake:

cannot resolve method 'encodeToString(byte[],?)' 
cannot resolve symbol 'DEFAULT'

How to resolve this error

resolvent:

I think you imported org.apache.commons.codec.binary.base64 in the file. Please recheck and try to use import android.util.base64. It will solve the problem that you cannot solve the method 'encodetostring (byte [],?)'
