as3 _ctx is null pozirk android in app purchases ANE

Question

I googled _ctx is Null and I was shocked to find nothing relating to Android. I am hoping this pose will help someone if we find the right answer.

Here is a link to the ANE I am using: https://github.com/pozirk/AndroidInAppPurchase

I have no idea where to go from here. It once worked now its not. :(

I am trying to use Pozirk's InAppPurchase.ane - which I have used before but suddenly its not working. I am not sure what changed. It may be, the ANE, or something in google play. Not sure but now its not working and I keep on getting this error:

_ctx is null.

Answer 1

You did not add ANE file to your project properly. This question was already asked and answered: http://inside.pozirk.com/2013/02/18/adobe-air-in-app-purchase-native-extensions/#comment-87 http://inside.pozirk.com/2013/02/18/adobe-air-in-app-purchase-native-extensions/#comment-89

Answer 2

My checklist, after tinkering FlashBuilder for 2 hours:

1) "project" > Properties > ActionScript Build Path > Native Extensions > Add ANE > "add InAppPurchase.ane"

2) "project" > Properties > ActionScript Build Packaging > Google Android > Native Extensions > "select package InAppPurchase.ane"

3) ... AS3 code uses the in-app-purchase API ...

4) The ANE seems to fail if you try to use it in debug mode; an exported APK should be used instead.

5) FlashBuilder > Project > Export Release Build:

• Verify that the ANE is included in the package (Native Extensions)
• Verify that your are using the correct signing certificate.

6) Copy the created APK to the Android device.

7) Install the APK using a file explorer.

8) The app finally runs, instead of crashing/hanging at startup.
