Android Question Out of memory with StringBuilder

[Alessandro71]

Any known memory limit with string builder?
This happened while building a JSON string

~e:java.lang.OutOfMemoryError: Failed to allocate a 150994952 byte allocation with 25165824 free bytes and 72MB until OOM, max allowed footprint 150793064, growth limit 201326592
~e: at java.util.Arrays.copyOf(Arrays.java:3260)

Sounds like you did a mistake somewhere.

Are you really building a 100mb+ json string?

pictures inside...
and I thought 150MB on a 3GB device should not be issue...
I'll switch to building and uploading a file instead

The OS will not let your app consume all the available memory and the case here is more strict as you need the memory block to be contiguous.
