Okay, it took me some time so I post my answer for others.
Of course you have to specify the place where you want to save it (but that's obvious) then create OutputStream:
String path = Environment.getExternalStorageDirectory().toString() + "/DCIM";
File file = new File(path, "test.txt");
FileOutputStream outputStream = null;
try {
outputStream = new FileOutputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
After this we create Metadata object and initialize it and then download it using metadata.getPathLower().
try {
Metadata pathMetadata = client.files().getMetadata("/test.txt");
client.files().download(pathMetadata.getPathLower()).download(outputStream);
Log.e("METADATA", pathMetadata.toString());
} catch (DbxException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
The strange this is that the getPathLower() returns "test.txt" but when we type it raw inside download() method it returns
java.lang.IllegalArgumentException: String 'path' does not match pattern
("/test.txt" doesn't work too).
It took me much time to make it work so I hope my answer helps someone to save this time.
Happy coding!
Glad to see you already got this working. For reference though, "/test.txt" should certainly work too, as that's the correct format. What did you get when you tried that? (Perhaps there was a typo?) You also shouldn't need the call to
getMetadataanyway if you already know the path.getPathLowerjust returns a string like "/test.txt" (not "test.txt", which wouldn't work as it's missing the leading slash).
