how much cache size available in android?

We have made a streaming player fo开发者_StackOverflow社区r android. now we want to store song data in the cash. How big the cache available for android app?


the documentation for getCacheDir() says

You should not rely on the system deleting these files for you; you should always have a reasonable maximum, such as 1 MB, for the amount of space you consume with cache files, and prune those files when exceeding that space.

However if you use getExternalCacheDir(), you can use as much storage as it is available on the sd-card
