Is there a simple way to have external properties for an android APK?

I have an android application that gets invoked through ADB on a desktop machine. I have a properties file on the desktop machine which the android application somehow needs to be aware of, but they need to be external to the APK.

On the desktop (which will invoke the activities within the APK via ADB) I c开发者_JAVA百科annot easily repackage the APK with the .properties file and then re-install the APK on the phone (I tried this via aapt, but it is not preferable because it removes the signature on the APK and I cannot easily resign the apk on the particular desktop machine).

I would rather not pass them via intent extras, as there are a lot of them, and I cannot use adb shell setprop because it doesn't work while the phone is running. I also cannot put them on external storage because I am not guaranteed the phone will have an SD card. Can I put them in "internal storage" somewhere (if that exists) ?

I basically need to be able to pass numerous properties onto the device when I install the APK, but I cannot put them in the APK itself, and not all the devices will have SD cards.

Any ideas ?
