I want to save a file on internal storage into a specific folder. My code is:
File mediaDir = new File("media");
if (!mediaDir.exists()){
mediaDir.createNewFile();
mediaDir.mkdir();
}
File f = new File(getLocalPath());
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
fos.write(data);
fos.close();
getLocalPath
returns /data/data/myPackage/files/media/qmhUZU.jpg
but when I want to create the media folder I'm getting the exception "java.io.IOException: Read-only file system". Any ideas how to write my files on internal phone storage in in folder media? Thanks.
You should use ContextWrapper like this:
ContextWrapper cw = new ContextWrapper(context);
File directory = cw.getDir("media", Context.MODE_PRIVATE);
As always, refer to documentation, ContextWrapper has a lot to offer.
