you need to add

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

under the <manifest> tag in your manifest file

Is this happening on android 6.0 as well? Then you will have to go for runtime permissions as well. Pre marshmallow-

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> in the android manifest file.

Marshmallow and above(Targeted SDK)- You should be checking if the user has granted permission of external storage by using:

    public  boolean haveStoragePermissions() {
    if (Build.VERSION.SDK_INT >= 23) {
        if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                == PackageManager.PERMISSION_GRANTED) {
            Log.v(TAG,"Permission is granted");
            return true;
        } else {

            Log.v(TAG,"Permission is revoked");
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            return false;
        }
    }
    else { //permission is automatically granted on sdk<23 upon installation
        Log.v(TAG,"Permission is granted");
        return true;
    }
}

Then make your activity implement OnRequestPermissionResult-

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(grantResults[0]== PackageManager.PERMISSION_GRANTED){
        Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);
        //resume tasks needing this permission
    }
}
