Can you provide file(s) that demonstrate the problem? Even the results of a gdalinfo dump may help.

Also, what do you have set for your Dalvik heap size to?

[bosborn]

This implementation loads the entire tiff file into memory for raster random read access. Your reported error occurred attempting to copy the file into memory. Allocation of ~537mb with a growth limit of ~537mb.

Try increasing the heap size.
