我正在尝试连接下面的网址。这工作正常但应用程序在执行后崩溃,任何想法? Logcat抱怨第77行 - connection = (HttpURLConnection)url.getContent();,我更改了connection = (HttpURLConnection)url.openConnection();,因为网址没有被执行。此代码在onClick Listener上的按钮内执行。提前谢谢。

URL url = null;
try {
    url = new URL("http://apps.smilemachine.com/smilefactory/api/v1.0/speedup");
} catch (MalformedURLException e) {
    e.printStackTrace();
}
HttpURLConnection connection = null;
try {
    connection = (HttpURLConnection)url.getContent();
} catch (IOException e) {
    e.printStackTrace();
}
try {
    connection.setRequestMethod("GET");
} catch (ProtocolException e) {
    e.printStackTrace();
}
try {
    connection.connect();
} catch (IOException e) {
    e.printStackTrace();
}

Log cat输出:
