如何在改进时出现错误消息： Timer is already running

Answer 1

错误消息是响应正文的一部分。这是一种非常简单的方法，可以访问它。

// Util method to make it easier to transform a stream into a byte array
static byte[] streamToBytes(InputStream stream) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    if (stream != null) {
        byte[] buf = new byte[1024];
        int r;
        while ((r = stream.read(buf)) != -1) {
            baos.write(buf, 0, r);
        }
    }
    return baos.toByteArray();
}

代码中的某处你会有类似的东西

try {
    yourRestApi.getSomeDataRestCall();
} catch (RetrofitError e) {
    if (e.getResponse != null) {
        TypedInput body = e.getResponse().getBody();
        byte[] bytes = streamToBytes(body.in());
        String charset = MimeUtil.parseCharset(body.mimeType());
        // This will be your error message
        String errorMsg = new String(bytes, charset);
    }
}
