Android Question Receive text using AsyncStreamsText (Error)

[mmanso]

Hi all,

I'm trying to receive simple text content through a server socket running in Android. From the foruns, I've found that I should use the AsyncStreamsText class.

I'm trying to but when I compile my project I get this error:

Any help?

Thanks.

Can you upload the project (File - Export as zip)?

Here it is.

The issue is that you are encoding the String to a Data object and then sending the Data object to the AsyncStream which expects a String.

You should have some warnings about 'Object converted to String. This is probably a programming mistake'.

I guess you are attempting to ensure that the String is UTF8 encoded in order to send it to the AsyncStream? But what you're actually doing is changing the data type of the string in question and then Asyncstream throws it's toys out of the pram as it is being sent a data type it isn't expecting.

Have you tried just sending the String as is, without the conversion?

It is better to name the variable AST as it is an AsyncStreamsText object, not AsyncStreams object.

AsyncStreams.Write - Expects an array of bytes.
AsyncStreamsText.Write - Expects a string.
