Installing android app on sdcard

Question

I developed an app which can install on sdcard or in mobile internal memory. I used android:installLocation attribute set to "auto".

Now the problem I am facing is when I run app on device then it shows me move to sdcard button enabled but when I uploaded the app to market and installed it from market then move to sdcard button is not enabled.

Any Idea where I am lagging.

Make sure your app is not copy-protected:

The Application Info screen now has either a “move to SD card” or “move to phone” button, but this is often disabled. Copy-protected apps and updates to system apps can’t be moved to the SD card, nor can those which are don’t specify that they work on the SD card.
