How do I write a byte array to a file in Android?
I think you'd better add close function of FileOutputStream for clear code
It works me perfectly
try {
if (!file.exists()) {
file.createNewFile();
}
FileOutputStream fos = new FileOutputStream(file);
fos.write(bytes);
fos.close();
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
Are you sure the file is created already?
Try adding this:
File file = new File(path);
if (!file.exists()) {
file.createNewFile();
}
/data/data/ is a privileged directory in Android. Apps can't write to this directory or read from it.
Instead, you should use context.getFilesDir()
to find a valid filename to use.
