Android 使用easyar 加载sd卡的图片资源报错

Question

E/EasyAR: Error: fail to load config: [{"images" :
    [{"image":"/storage/emulated/0/armagic/icon/0.png","name":"name0","uid":"0"}]}]

我调用的是

private void loadExternalFromJsonFile(ImageTracker tracker, String path) {
    for (ImageTarget target : ImageTarget.setupAll(path, StorageType.Absolute)) {
        tracker.loadTarget(target, new FunctorOfVoidFromPointerOfTargetAndBool() {
            @Override
            public void invoke(Target target, boolean status) {
                Log.e("HelloAR", "loadAllFromJsonFile: " +
                        String.format("load target (%b): %s (%d)", status, target.name(), target.runtimeID()));
            }
        });
    }
}

json path传的是 {"images" :
      [{"image":"/storage/emulated/0/armagic/icon/0.png","name":"name0","uid":"0"}]}
