Solution 1:

Add these two to Mainfest.xml file

<uses-permissionandroid:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Then you need to request permission before any operation dynamically like below

if (ContextCompat.checkSelfPermission(thisActivity,Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {
    // Permission is not grantedif (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
        // Show an explanation to the user *asynchronously* -- don't block// this thread waiting for the user's response! After the user// sees the explanation, try again to request the permission.
    } else {
        // No explanation needed; request the permissionActivityCompat.requestPermissions(thisActivity,
                newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                MY_PERMISSIONS_WRITE_EXTERNAL_STORAGE);
    }
}

Solution 2:

After android 6.0, only declare permissions request in AndroidManifest.Xml is not enough, you also explicitly request corresponding permissions before doing some task.

ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    1);

and

@OverridepublicvoidonRequestPermissionsResult(int requestCode,
    String permissions[], int[] grantResults) {
    switch (requestCode) {
        case1:
            {
                if (grantResults.length > 0 &&
                    grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission was granted, do something you want        
                } else {
                    // permission denied
                    Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
                }
                return;
            }
    }
}
