Android Question B4XWriteObject with huge map

[GiovanniPolese]

Hi to All. I have a huge map and when I try to save it with RandomAccesFile.WriteObject, my App crashes. with:

java.lang.OutOfMemoryError: Failed to allocate a 92274696 byte allocation with 49507712 free bytes and 47MB until OOM, target footprint 536870912, growth limit 536870912

I am wondering if it exists any official way to by pass this problem, or I have to invent a trick dividing the map in chunks.

Thanks for any hint.

I'm curious as to why you would have a 92 megabyte map? Surely you could maintain that much information in a SQLite or similar DB more efficiently?

Try increasing -Xmx limit

Try increasing -Xmx limit : what does it mean?

 

[Daestrum]

it tells the java virtual machine how much memory it can use

 

[GiovanniPolese]

And where to set it (and how)? It may be a solution .. but I have no idea on this subject --

I already set LargeHeap option in Manifest.

Anyway the solution is trivial: write each element in a loop, or make a custom bufferization. Nothing dramatic.
