IAB startSetup NullPointerException

I am attempting to setup In-App Billing in my application. I haven't got very far and am running into a null pointer exception when trying to start my IabHelper. I am following this google tutorial.

import com.iabtest.util.IabHelper;
import com.iabtest.util.IabResult;

public class MainActivity extends Activity
{
    IabHelper mHelper;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String base64EncodedPublicKey = "My_secret_key";

        mHelper = new IabHelper(this, base64EncodedPublicKey);
        mHelper.enableDebugLogging(true); //Turned on to try to help solve the issue
        Log.d("TEST", "Starting setup.");
        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener()
        {
            public void onIabSetupFinished(IabResult result)
            {
                Log.d("TEST", "Setup finished.");

                if(!result.isSuccess())
                {
                    // Oh noes, there was a problem.
                    Log.d("TEST", "Problem setting up in-app billing: " + result);
                    return;
                }

                //IAB SET UP!
                Log.d("TEST", "IAB ready");
            }
        });
    }
}

In the below logcat, it appears that the null pointer exception is being triggered in IabHelper.java on line 267. Since this is google code, I'm not sure how to fix this. Here is line 267.

if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {

Here is my LogCat with the error:

Edit: I'm still not sure the reason for the error. However, I have found a useful tutorial that has been better than the google documentation. http://www.techotopia.com/index.php/Integrating_Google_Play_In-app_Billing_into_an_Android_Application_%E2%80%93_A_Tutorial

回答1:

Another fine example of Googles 'write once, let others fix our problems'. Even at this moment (June 2014) the 'patch' is still not in the released sdk. To solve the problem replace

 if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {

with

  PackageManager pm=mContext.getPackageManager();
  List<ResolveInfo> intentServices = pm.queryIntentServices(serviceIntent, 0);
  if (intentServices != null && !intentServices.isEmpty())

Then in the dispose code

replace

  if (mContext != null) mContext.unbindService(mServiceConn);

with

  if (mContext != null && mService!=null) mContext.unbindService(mServiceConn);

I hope this helps.

回答2:

please add jar file of google play services.this is error regrarding missing google play service

回答3:

Probably this issue relates to the issue raised here

The updated code hasn't been pushed out to the SDK Manager yet, but you can view all the changes related to this issue here:

https://code.google.com/p/marketbilling/source/detail?r=7ec85a9b619fc5f85023bc8125e7e6b1ab4dd69f

There are 4 files affected by the issue. Make the changes they suggest and see if you still run into the same issue.

回答4:

In fact, it is here that is returning null.

Intent serviceIntent = getExplicitIapIntent();

Treat this situation:

 Intent serviceIntent = getExplicitIapIntent();

        if(serviceIntent != null) {

            if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {
                // service available to handle that Intent
                mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
            }
        }
