ANDROID - zip file problem

DEXIT D.

Hello, I making android app with dropbox API and I have a problem. My app zips folder on android device and uploads it on dropbox, it works. If I download zip file from dropbox to my PC, I can extract it but if I download this file using dropbox api method getFile with code below, downloaded zip file is corrupted and archive showing error "end of central directory signature not found"

Here is the code:

protected Boolean doInBackground(Void... params) {

String inPath = Environment.getExternalStorageDirectory() + dropboxFile;
File file=new File(inPath);
FileOutputStream mFos = null;

try {

mFos = new FileOutputStream(file);
} catch (FileNotFoundException e){

return false;
}

try {
dbAPI.getFile("/" + dropboxFile, null, mFos, null);
} catch (DropboxException e) {
e.printStackTrace();
}

return true;
}

Can you help me please?

How are you downloading the file when it does work? Are you using the Dropbox web site? Can you compare the file you get that way to the file you get via the API? E.g., compare the file lengths and/or hashes.

Some other things that would be helpful in debugging this:

- the rest of the relevant code (e.g., what do you do with mFos?)

- any output/errors you get from the code
