Assets are normally stored compressed, so currently opening it requires uncompressing into an in-memory buffer. From that perspective, 1MB is pretty big -- it's over 1% of the total memory available to the kernel and all apps on the G1! To get around this, you can store your file uncompressed -- the new aapt has an option to turn off compression for custom fie extensions -- so you can read it directly from the .apk as an AssetFileDescriptor. It would also be nice to support streaming access that uncompresses while you read... patches welcome. :) > 2.

PNGs, MP3s, etc are not compressed in the .apk since their data is already compressed. > 2. Can I change the file size limit, or is it a fixed feature? Fixed. > 3.

Can I delete the resources from raw or assets at runtime (or is this > totally invalid since the compiler sets up R.raw to have methods > representing the files) to save space? Not at all, sorry. You .apk is completely read-only. > 5. How big is too big an application? (mine is a large word dictionary > and the whole app after first run takes 4 meg) Given the storage space on the G1, that is pretty big -- 5-10% of the space available to all applications, their private data (Gmail messages and such), and the browser cache. That size of an .apk will probably reduce the number of users you have, depending on how valuable people find the app to be. -- 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.
