I can use the PackageManager and retrieve the info for that same package, so I am pretty sure I have the name correct and the app is installed. Do you have any ideas about what might be wrong? Well no idea from just your paragraph description there. :) This API certainly works -- it is used a lot, for things like inflating the UI of app widgets. I am using a sharedUserId, however, the two apps are unified. In fact, I would much rather have just a SINGLE app. However, I want the user to be able to install the app to the SD card, but it includes a AppWidget component (which is optionally used) which cannot reside on the SC card. This seems to be forcing me to create two apps, may main app, and a separate app to handle the AppWidget. If there is a better way to do this, I am all ears. Oh my. Well personally I would really strongly discourage doing that. I think you are going to end up with continual pain in app maintenance, not to mention support for your users dealing with multiple apps like this. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

The call to manager.getPackageInfo works, but the call to GetPackageContents returns null. What is GetPackageContext in your code? Is that just a typo and should be getPackageContext? I actually tend to agree, but I really hate to force the user to install the app to internal memory (there is a fair amount of content). The feedback I have gotten so far from the users that I have asked is that they would rather see a separate app than loose the ability to install on the SD card. Is there ANY other way to deal with this? Well for transferring data between apps, I will say the same thing I already have: I would very much recommend using a receiver, service, or content provider. Don't use shared user IDs. Your widget could just for example send a broadcast to your app when it needs to populate data. As a bonus, your main app could be the one in charge of the data and send a broadcast to the widget app when it has changed to give it the new data. I think you'll find this a much cleaner solution than trying to directly access data files. At any rate, offering your users a small add-on app that they can optionally download to provide a widget is probably not too bad I guess. Heck you could turn it into an advantage and make it paid so it is an additional feature they can purchase for your app. ;) But I do think you should architect it so that the interaction between these pieces is through app components, not data. It will result in a much cleaner and more maintainable design. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
