Send JSON object via HttpPost method

by Wayne Wenthin » Wed, 09 Sep 2009 05:39:03 GMT


 A snippet for what I do...
public HttpResponse updateGirl(String url, Pawn girl, int pawnID) {
HttpClient httpclient = new DefaultHttpClient();
HttpPut httpput = new HttpPut(url);

// Execute the request

try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
39);
nameValuePairs.add(new BasicNameValuePair("id", Integer
.toString(pawnID)));
......  Many nameValuePairs later.....


httpput.addHeader("Content-Type",
"application/x-www-form-urlencoded");
httpput.setEntity(new UrlEncodedFormEntity(nameValuePairs,
HTTP.UTF_8));
 HttpResponse response = httpclient.execute(httpput);
return response;

} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
// e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;

}

Hope that helps.   I struggled with it for a couple of weeks before I found
a site that had a good source.

Send JSON object via HttpPost method

by Alok Kulkarni » Wed, 09 Sep 2009 16:44:42 GMT


 ey Wayne, thanks a lot..
I have also got a solution parallely which i would like to post

URL url = new URL(serverURL);

// open the conncetion
HttpURLConnection connection =
(HttpURLConnection)url.openConnection();

// Let the run-time system (RTS) know that we want input.
connection.setDoInput(true);
// Let the RTS know that we want to do output
connection.setDoOutput(true);
// No caching, we want the real thing
connection.setUseCaches(false);
// set the content type property
connection.setRequestProperty("Content-type",strContenttype);

// set request method
connection.setRequestMethod("POST");
// create the post body to send
String content = credDevPair.toString();
Log.i("Request ====....... ",content);
DataOutputStream printout = new DataOutputStream (
connection.getOutputStream () );

// send the data
printout.writeBytes(content);
printout.flush();
printout.close();
String output =
convertStreamToString(connection.getInputStream());
Log.i("Response 1....... ",output);
// A Simple JSONObject Creation
JSONObject json=new JSONObject(output);

Log.i("Praeda","<jsonobject>\n"+json.toString()+"\n</jsonobject>");

// A Simple JSONObject Parsing
JSONArray nameArray=json.names();
JSONArray valArray=json.toJSONArray(nameArray);
for(int i=0; i<valArray.length() ;i++)
{

Log.i("Praeda","<jsonname"+i+">\n"+nameArray.getString(i)+"\n</jsonname"+i+">\n"

+"<jsonvalue"+i+">\n"+valArray.getString(i)+"\n</jsonvalue"+i+">");
}
//BufferedReader input = new BufferedReader ( new
InputStreamReader(connection.getInputStream()) );

}catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

}catch(Exception ex)
{

}

}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the
BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which
means
* there's no more data to read. Each line will appended to a
StringBuilder
* and returned as String.
*/
BufferedReader reader = new BufferedReader(new
InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}

return sb.toString();
}

Send JSON object via HttpPost method

by Wayne Wenthin » Thu, 10 Sep 2009 08:58:06 GMT


 ep that is what I vaguely based mine on.   I recognize the Praeda line.   I
had to modify mine because I was not sending back an array of json objects
but a specific one that I handle based on the ID on the backend with ruby.

1. Android setBackgroundResource release memory?

Hi, I have 2 quiet big Animations each 50pics a 20kb
Both defined as Animations .xml

One I let start from the beginning and the second after a button
click.

    //Start immediatly
      imgView.setBackgroundResource(R.layout.anim1);
                        rocketAnimation = (AnimationDrawable)
imgView.getBackground();

    //Start after button click
      imgView.setBackgroundResource(R.layout.anim2);
                        rocketAnimation = (AnimationDrawable)
imgView.getBackground();

It works fine, till i hit the button and assign the second anim to my
view

    08-22 14:56:03.886: DEBUG/AndroidRuntime(1541): Shutting down VM
    08-22 14:56:03.886: WARN/dalvikvm(1541): threadid=3: thread

    08-22 14:56:03.886: ERROR/AndroidRuntime(1541): Uncaught handler:

    08-22 14:56:04.096: ERROR/AndroidRuntime(1541):

    08-22 14:56:04.096: ERROR/AndroidRuntime(1541):     at
android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)

It looks definitly that each animation for itself is fine (i could
even set anim2 at the autostart). but BOTH will exceed the memory.


Btw. on my Nexus One it works perfect. Where it fails is on G1 1.6
(even in Simulator).

So HOW would I release anim1 first before I assign anim2 ??


thx

2. Unable to build android image as described in the porting guide...

I have followed the instructions in the porting guide (http://
source.android.com/porting/index.html). I have set up everything as
described there and always end up with a failed build...

The error message I get is:
Install: out/target/product/emh-board-release1/system/app/
VpnServices.apk
make: *** No rule to make target `out/target/product/emh-board-
release1/obj/lib/libaudio.so', needed by `out/target/product/emh-board-
release1/obj/SHARED_LIBRARIES/libaudioflinger_intermediates/LINKED/
libaudioflinger.so'.  Stop.

I have fetched the external/alsa-lib, external/alsa-utils/ and
hardware/alsa_sound and this didn't help... Any ideas what might be
going wrong... Just for the record, I'm using the latest code.
