Calling startIntentSenderForResult from Fragment (Android Billing v3)

Question

The new Android Billing v3 documentation and helper code uses startIntentSenderForResult() when launching a purchase flow. I want to start a purchase flow (and

Answer 1

I suggest two solutions:

1.) Put the IabHelper mHelper on the activity and call the IabHelper from the fragment.

Something like:

To use this solution, Declare IabHelper as public in the activity and use a method to call the launcher from the Fragment.

public class MyActivity extends Activity{

    public IabHelper mHelper

    public purchaseLauncher(){

    mHelper.launchPurchaseFlow(this, SKU_GAS, 10001,   
         mPurchaseFinishedListener, "bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ");

   }

    /*The finished, query and consume listeners should also be implemented in here*/
}

public class FragmentActivity extends Fragment{

      MyActivity myAct = (MyActivity) getActivity();

      myAct.purchaseLauncher();

}

2.) In onActivityResult, call the appropriate fragment that contains the IabHelper object. Appropriate fragment can have an access method to the helper object.

protected void onActivityResult(int requestCode, int resultCode,Intent data)    
{
    super.onActivityResult(requestCode, resultCode, data);

    FragmentManager fragmentManager = getSupportFragmentManager();
    Fragment fragment = fragmentManager.findFragmentByTag("YourTag");       
    if (fragment != null)
    {
        ((MyFragmentWithIabHelper)fragment).onActivityResult(requestCode, resultCode,data);
    } 
}

Answer 2

You need to pass fragment and data to parent activity, then call fragment onActivityResult from the parent activity.

like this

in fragment:

HomeActivity activity = (HomeActivity) getActivity();
activity.purchaseLauncher(this, mHelper, productDTO.getSku(), RC_REQUEST, mPurchaseFinishedListener, PAYLOAD);

in parent activity:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (storeFragment != null) {
            storeFragment.onActivityResult(requestCode, resultCode, data);
        }
    }

    public void purchaseLauncher(StoreFragment storeFragment, IabHelper mHelper, String sku, int requestCode, IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener, String payload) {
        this.storeFragment = storeFragment;
        mHelper.launchPurchaseFlow(this, sku, requestCode, mPurchaseFinishedListener, payload);
    }

Answer 3

You need to call

super.onActivityResult(requestCode, resultCode, data);

at the beginning of your Activity's and Fragment's onActivityResult to cascade the Results to the fragments.

In my FragmentActivity this reads as

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // No action here, call super to delegate to Fragments
    super.onActivityResult(requestCode, resultCode, data);
}

Answer 4

1) You should modify your resultCode (RC_REQUEST) to put fragment index to it.

int rc_reqest = RC_REQUEST +  ((getActivity().getSupportFragmentManager().getFragments().indexOf(this)+1)<<16)  ;      
mHelper.launchPurchaseFlow(getActivity(), sku, rc_reqest ,mPurchaseFinishedListener, payload);

2) in IabHelper.launchPurchaseFlow(...)

change mRequestCode = requestCode

to

mRequestCode = requestCode&0xffff;

Answer 5

From SDK 24 and above, there is a startIntentSenderForResult method available in support Fragment also, which works as intended. Note that there is an additional Bundle parameter, which can be passed as null. Thus, final code will be:

startIntentSenderForResult(pendingIntent.getIntentSender(),
    1001, new Intent(), Integer.valueOf(0), Integer.valueOf(0),
    Integer.valueOf(0), null);

Of course, for API 23 and below, we will still need to use the tricks described in other answers.
