android 6.0 需要手动访问权限

if (ContextCompat.checkSelfPermission(ShareCodeActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {    ActivityCompat.requestPermissions(ShareCodeActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 54);    Log.i("-->", "权限申请");}
