Raising (Something Like) a Tweet

String responseBody=client.execute(post, responseHandler);

JSONObject response=new JSONObject(responseBody);

}

catch (Throwable t) {

Log.e("Patchy", "Exception in updateStatus()", t);

goBlooey(t);

}

}

private void goBlooey(Throwable t) {

AlertDialog.Builder builder=new AlertDialog.Builder(this);

builder

.setTitle("Exception!")

.setMessage(t.toString())

.setPositiveButton("OK", null)

.show();

}

private View.OnClickListener onSend=new View.OnClickListener() {

public void onClick(View v) {

updateStatus();

}

};

}

Here, we:

• Set up an DefaultHttpClient instance for accessing the Apache

HttpClient engine

• Get access to our EditText widgets from the layout


• On a Send button click, call updateStatus()


• In updateStatus(), we create an HttpPost object to represent the

request, fill in the authentication credentials, fill in the status as a

form element, turn the whole thing into a valid HTTP POST

operation, execute it, and parse the response as a JSON object

If things work, at present, we do nothing to update the activity; if an

Exception is raised, we log it to the Android log and raise an AlertDialog.

You also need to add the INTERNET permission to your AndroidManifest.xml
