In the application a file is downloaded and it works in a phone with kitkat, but when I did the test in another phone with Marshmallow, it is truncated, the error that shows in the logcat is:
java.lang.SecurityException: No permission to write to /storage/emulated/0/Download/Score/Sample.txt: Neither user 10060 nor current process has android.permission.WRITE_EXTERNAL_STORAGE.
here the code:
