On iOS/windows I can create a osg::Image object by this:

     osg::ref_ptr<osg::Image> icon = osgDB::readRefImageFile(filePath);

the filePath param could be the "Resource/a.png", which is a relative path in the project. but this could not work in Android. I also tried using an absolute path like：

"/storage/emulated/0/res/a.png"

the path was the full sd card path to a.png, but didn't work either.

The Image object was used to be the icon of a osgEarth::Annotation::PlaceNode:

osg::ref_ptr<osg::Image> icon = osgDB::readRefImageFile(filePath);
node->setIconImage(icon.get());

On iOS, the icon could be displayed, but didn't display on Android. I am certain the problem was the osg::Image object didn't create properly on Android.

I appreciate very much if anyone could help. Thanks.

When you say it "didn't work", can you give details about what went wrong? Did you assign your app the "Storage" permission in order to access that path? – XenonofArcticus Feb 12 '19 at 19:37
hi @XenonofArcticus, thanks for replying. I edit the question for more details so you can know what I mean. – Charles Yao Feb 13 '19 at 01:21
@XenonofArcticus the app has the "Storage" permission. – Charles Yao Feb 13 '19 at 01:30
