Android recently doing a program, copying the database file to a sd, this great little database file several M, I think in code, I tried a couple of hours, that is not successful, a check information, to know ,

In Anroid, when programmatically to transfer a file storage system, android program the size of the file to read and write is limited

1. Uncompressed files generally can not operate 1MB, or not properly written to the destination file

2. Zip file does not have this requirement

So, in general, when we read and write files more than 1MB, then you can add the file name after the name of a compressed file that, for example. Mp3,. Jpq etc.

For general non-extension or as. Txt file so the system are identified as uncompressed files.
