This is sort of a java question too… How to read in a large array of chars, quickly?
I have a file on the /sdcard/ with a million chars (2 bytes each) that I would like to read in quickly. It is a binary file written from another system and I cannot change it. It can be read into a byte[] array extremely quickly with a statement like // dInStream is an open DataInoutStream // This is a really, really fast operation on Android byte[] rBuffer = new byte[2*1000000]; // Yes I know this is a lot for Android numBytesRead = dInStream.read(rBuffer, 0, 2*1000000); But then to get the data into a char[] array is evading me. I have tried lots of stuff from java.nio like ByteBuffers converting to CharBuffers and the get methods and they will do the conversion but they are so very S L O W. It takes < 1 sec to do the dInStream.read call and then like 30 seconds to walk over the wraped ByteArray.asCharBuffer using the various get methods. For a sec I thought ByteBuffer.asCharBuffer.array() was going to save the day. But it exceptions out because the wrap of the byte[] array is owned by the ByteBuffer, not the CharBuffer. Is there any way just to do the dInStream.read directly into the char array or maybe “cast” the byte[] array to a char[] array? Thanks in advance for any help! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
