When I run the below Java for Android code, I get a NullPointerException on the line that calls getSkuDetails in the doInBackground method in the GetItemList class. But when I step through in the debugger, all the parameters to getSkuDetails have values. pName is not an empty string and querySkus has two items in it. The exact error message I'm getting is "Attempt to invoke interface method 'android.os.Bundle com.android.vending.billing.IInAppBillingService.getSkuDetails(int, java.lang.String, java.lang.String, android.os.Bundle)' on a null object reference." Does anyone know why?

The TextView reference variable (i.e. textview) is accesed which gives a NullPointerException. To Handle the NullPointerException smoothly without making the app crash, we use the “ Try – Catch Block ” in Android. Try: The Try block executes a piece of code that is likely to crash or a place where the exception occurs.
Null Pointer Exception In Java. NullPointerException is a RuntimeException. In Java, a special null value can be assigned to an object reference. NullPointerException is thrown when program attempts to use an object reference that has the null value. These can be: Invoking a method from a null object.
It is, therefore, possible for a null pointer to slip through the net if you are initializing lots of objects on the fly. This is why it’s useful to include measures to prevent null pointer exceptions during runtime. The easiest way to do this?
In fact, null pointer exceptions are so common and so damning, that they are referred to as “the billion-dollar mistake.” Ouch! In this post, we’re going to unwrap the phrase to discover exactly what it means and what you should do when you encounter a null pointer exception in your own code!
What could probably be happening is that mServiceConn instance of ServiceConnection connection class takes some time to connect, and until the connection is established, mService remains null.
To fix this, please try the following code:
public class AvailableCards extends Activity {
IInAppBillingService mService;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_available_cards);
String packagename = this.getPackageName();
TextView priceView = (TextView)findViewById(R.id.availablePrice);
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);
new GetItemList(packagename, priceView).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;
private TextView pView;
GetItemList(String packagename, TextView priceView){
pName = packagename;
pView = priceView;
}
@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 mFirstIntermediate;
String mSecondIntermediate;
if (sku.equals("i001")) mFirstIntermediate = price;
else if (sku.equals("i002")) mSecondIntermediate = price;
pView.setText(sku + ": " + price);
}
}
} catch (NullPointerException ne) {
Log.d("Synch Billing", "Error Null Pointer: " + ne.getMessage());
ne.printStackTrace();
}
catch (RemoteException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error Remote: " + e.getMessage());
e.printStackTrace();
}
catch (JSONException je) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error JSON: " + je.getMessage());
je.printStackTrace();
}
return null;
}
}
