Re: [android-developers] Re: OutofMemory Excepton error in android

Actually even 5K can crash his app... it all depends on what he did before the allocation.

Android has a nasty bug of claiming you dont have enough memory even if your heap has more than enough free space if it grew close to its maximum value previously (and dont't forget fragmentation as well, 10MB of free heap doesn't mean you can allocate 10MB).

Basically i found that if i get a OOM exception when the allocated size isn't something  enormous, it's usually because is misbehaved earlier :)

So my suggestion to Karunakar (assuming he can't do random reads on the file and the file isn't really big) is to profile his app and see if he needs to do some fixing up before he gets to the point of reading the file.

Other than that, he can always try the big heap flag or just dump everything to native heap.

how big is the file you're reading..?

In general, you can't allocate that much space on Android.  To combat
this you need to be able to do lazy I/O.

But ... are you trying to read in a dictionary (using apertium?).  I'd
guess this is a few megabytes at least right?  Having a megabyte or
two on the heap won't necessarily crash your app, but having more than
that certainly can!  (This of course, depends on the device..)
