When Android makes an external connection and this url is not available it returns an error.
How to customize an error as in the example below:
java.io.IOException: Error response: 401 Service Unavailable
for something like:
Erro: Serviço não dospinível
I hope I have been clear in the question.
The error is already being customized by the library / method that is producing the IOException . In this case the solution would be to capture this exception in a block catch() and throw a new IOException with the custom text. If you want to customize this text only when the% original_contains exactly the text "Error response: 401 Service Unavailable" will have to make a comparison of this string with the one that is returned by IOException (using exception.getMessage() ).
For example:
try {
...
player.playAsync(url);
...
} catch (IOException e) {
if ("Error response: 401 Service Unavailable".equals(e.getMessage()) {
throw new IOException("Erro: Serviço não disponível");
} else {
throw e;
}
}
