Java for Android Call getPackageName() from within an AsyncTask

I am working on an Android app using InAppBilling. I recently moved the following code from my main Activity to an AsyncTask, as recommended by Google:
class GetItemList extends AsyncTask<Integer, Integer, Long> {
IInAppBillingService mService;
ServiceConnection mServiceConn = new ServiceConnection() {
#Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
#Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
}
};
#Override
protected Long doInBackground(Integer... params) {
ArrayList<String> skuList = new ArrayList<String> ();
skuList.add("i001");
skuList.add("i002");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
Bundle skuDetails = null;
try {
skuDetails = mService.getSkuDetails(3, getPackageName(), "inapp", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> responseList
= skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList) {
JSONObject object;
object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
String mPremiumUpgradePrice;
String mGasPrice;
if (sku.equals("i001")) mPremiumUpgradePrice = price;
else if (sku.equals("i002")) mGasPrice = price;
}
}
} catch (RemoteException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error Remote: " + e.getMessage());
e.printStackTrace();
}
catch (JSONException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error JSON: " + e.getMessage());
e.printStackTrace();
}
return null;
}
}
My problem is that the call to getPackageName() (the first line of the try block) is giving the error, "The method getPackageName() is undefined for the task GetItemList." How do I call getPackageName() from within an AsyncTask? I've tried GetContextWrapper.getPackageName(), getApplicationContext.getPackageName(), and getResources.getPackageName().
Corrected code, based on mixel's answer below:
package com.myknitcards;
import java.util.ArrayList;

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_available_cards);
String packagename = this.getPackageName();
new GetItemList(packagename).execute();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.available_cards, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
class GetItemList extends AsyncTask<Integer, Integer, Long> {
private String pName;
GetItemList(String packagename){
pName = packagename;
}
IInAppBillingService mService;
ServiceConnection mServiceConn = new ServiceConnection() {
#Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
#Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
}
};
#Override
protected Long doInBackground(Integer... params) {
ArrayList<String> skuList = new ArrayList<String> ();
skuList.add("i001");
skuList.add("i002");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
Bundle skuDetails = null;
try {
skuDetails = mService.getSkuDetails(3, pName, "inapp", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> responseList
= skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList) {
JSONObject object;
object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
String mPremiumUpgradePrice;
String mGasPrice;
if (sku.equals("i001")) mPremiumUpgradePrice = price;
else if (sku.equals("i002")) mGasPrice = price;
}
}
} catch (RemoteException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error Remote: " + e.getMessage());
e.printStackTrace();
}
catch (JSONException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error JSON: " + e.getMessage());
e.printStackTrace();
}
return null;
}
}

Add constructor to GetItemList that accepts packageName and assigns it to private field. Then use it in mService.getSkuDetails().
And when you instantiate GetItemList in your activity pass value that returned by getPackageName() to GetItemList constructor.

HTML is not JSON, and it can not be parsed into JSONObjects. The top answer for org.json.JSONException: Value <!DOCTYPE of type java.lang.String cannot be converted to JSONObject is pretty good at explaining this further.

Android: how to restart a method with a button click

I have a button that gets month and year from spinners then calls an Async task, which read json data. That part works fine But if I try and change the month and year then click the button again it does nothing. I have to press back to reload the page to click the button again to get different results.
Here is my code. Can any of you smart folks please help me.

How do you process results of your InvoiceAsyncTask? Do you implement a callback from your AsyncTask's onPostExecute() to the activity?
Maybe the sample below will help you.
First, implement AsyncTask class with callback interface:
public class ServerRequestAsyncTask extends AsyncTask<String, Void, ServerResponseDetails> {
public ServerRequestAsyncTask(Fragment fragment, ServerRequestDetails request) {
mFragment = fragment;
mRequest = request;
}
public interface OnServerRequestAsyncTaskCompletedListener {
void onServerRequestAsyncTaskCompleted(ServerResponseDetails response);
}
public void cancel() {
if (mHttpGet != null && !mHttpGet.isAborted()) mHttpGet.abort();
cancel(true);
}
And also add onPostExecute():
#Override
protected void onPostExecute(ServerResponseDetails response) {
if (mFragment != null) mFragment.onServerRequestAsyncTaskCompleted(response);
}
I call AsyncTask from Fragment, but you can use it with Activity instead.
Then, in your Activity you implement interface:
#Override
public void onServerRequestAsyncTaskCompleted(ServerResponseDetails response) {
// do what you need here, then 'finish' task by setting mServerRequest to null
mServerRequest = null;
}
And to execute AsyncTask:
protected ServerRequestAsyncTask mServerRequest = null;
public boolean isServerRequestRunning() {
return (mServerRequest != null);
}
public void cancelServerRequest() {
mServerRequest.cancel();
}
public void sendServerRequest(Fragment fragment, ServerRequestDetails request) {
if (Application.isNetworkAvailable()) {
if (!isServerRequestRunning()) {
mServerRequest = new ServerRequestAsyncTask(fragment, request);
mServerRequest.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR,
{params});
}
}
}
mServerRequest variable holds reference to currently executed task. You can call mServerRequest.cancel() if need to abort.

Thanks Everyone But I have figured it out. I needed to cancel the Async task in the post execute method.
#Override
protected void onPostExecute(String result) {
try {
JSONArray jArray = new JSONArray(result);
invoice(jArray);
cancel(true);
isCancelled();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Not sure what I am doing wrong, I tried various things and trying to look up different ways to go about doing this and none of them have worked... maybe it is something more simple than I see... the problem I think lies in the private class within this class.

I haven't read your code in great detail, but I suspect a strong contributor is this:
HttpPost httppost = new HttpPost("http://127.0.0.1:3000/wardrobe");
If you're using the emulator it's probably more likely you want to connect to "10.0.2.2". which is:
Special alias to your host loopback interface (i.e., 127.0.0.1 on your
development machine)
