Android - save file to Device's "data" folder

Question

I need to save some files in the device's "data" folder, because some other application needs them.

I've tried

new File("/data/filename").createNewFile();

but I get

java.io.IOException: open failed: ENOENT (No such file or directory)

Is the path I'm using wrong?

Try this:

ContextWrapper cw = new ContextWrapper(getApplicationContext());
File directory = cw.getDir("filename", Context.MODE_PRIVATE);

Are you talking about the data folder in root? Then the device must be rooted and you need root permission.
