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);
}
}
