I just spent a minute knocking out a test case over a cup of tea. Seems to
work fine for me on WIFI, GPRS, and 3G.
Tom.
void testConnection() {
TextView view = (TextView) findViewById(R.id.message);
HttpURLConnection conn = null;
try {
URL url = new URL("
http://finance.yahoo.com/d/quotes.csv?s=GOOG+T&f=sl1c1p2";);
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.connect();
Reader reader = new InputStreamReader( conn.getInputStream() );
StringWriter writer = new StringWriter();
for (int c = reader.read(); c >= 0; c = reader.read())
writer.write(c);
view.setText(writer.toString());
} catch (IOException e) {
Log.e("test", "connection test failed", e);
} finally {
if (conn != null) conn.disconnect();
}
}
