我正在尝试将日期从 Android 发送到 PHP。我在启动屏幕活动中添加了一些代码以便能够做到这一点。但是，它给了我一个错误。我不知道我错过了什么。下面是完整的代码：
public class Splash extends Activity {
DBAdapter db = new DBAdapter(this);
protected int _splashTime = 5000;
private Thread splashTread;
private String android_id;
private String formattedDate;
SharedPreferences prefs = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Calendar c = Calendar.getInstance();
System.out.println("Current time => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("MM'/'dd'/'yyyy");
formattedDate = df.format(c.getTime());
android_id =Secure.getString(this.getContentResolver(),
Secure.ANDROID_ID);
Log.d("IP", getIpAddress());
Log.d("id", android_id);
Log.d("date",""+ formattedDate);
final Splash sPlashScreen = this;
splashTread = new Thread() {
@Override
public void run() {
try {
synchronized(this){
wait(_splashTime);
}
} catch(InterruptedException e) {}
finally {
finish();
Intent i = new Intent();
i.setClass(sPlashScreen, Tab.class);
startActivity(i);
try {
splashTread.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
splashTread.start();
prefs = getSharedPreferences("com.sample.package", MODE_PRIVATE);
}
@Override
public void onBackPressed() {
}
public String getIpAddress() {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
Log.e("LOG", ex.toString());
}
return null;
}
@Override
protected void onResume() {
super.onResume();
if (prefs.getBoolean("firstrun", true)) {
prefs.edit().putBoolean("firstrun", false).commit();
Log.d("FIRST LAUNCH?", "YES");
sendData();
}else{
Log.d("FIRST LAUNCH?", "NO");
}
}
public void sendData() {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://whatever.php");
try{
List<BasicNameValuePair> deviceInfo = new ArrayList<BasicNameValuePair>(3);
deviceInfo.add(new BasicNameValuePair("ip", getIpAddress()));
deviceInfo.add(new BasicNameValuePair("date", formattedDate));
deviceInfo.add(new BasicNameValuePair("id", android_id));
httppost.setEntity(new UrlEncodedFormEntity(deviceInfo));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
Log.i("postData", response.getStatusLine().toString());
} catch (IOException e) {
Log.e("log_tag", "Error in http connection "+e.toString());
}
}
}
我把活动的所有代码贴出来了，这样比较容易理解。
