Calling toString() on an InputStream doesn't do what you think it does. Even if it did, a PDF contains binary data, so you wouldn't want to convert it to a string first.

What you need to do is read from the stream, write the results into a ByteArrayOutputStream, then convert the ByteArrayOutputStream into an actual byte array by calling toByteArray():

InputStream inputStream = new FileInputStream(sourcePath);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

int data;
while( (data = inputStream.read()) >= 0 ) {
    outputStream.write(data);
}

inputStream.close();
return outputStream.toByteArray();
