Android OS by default does not allow applications to access each others private folders. To be able to read files that are in another applications folder either:

1) you need to have both applications installed using same user id. Add this to both manifests:

android:sharedUserId="com.xx.xx"

And then you need to put your application into /system/app/ folder and reboot the phone. It should be installed automatically during the boot.
