我用九段SDK V.1.4在Android工作室包：eu.kudan.ar九段AR簡單示例的Android不起作用[解決]
該項目建立沒有錯誤，但是當我運行應用程序，我有這個錯誤：

資產進口良好。 問題是：
trackableSet.loadFromAsset("demo.KARMarker");
這是我的活動：
public class MainActivity extends ARActivity implements ARImageTrackableListener {
public void onCreate(Bundle savedInstanceState) {
// set api key for this package name.
ARAPIKey key = ARAPIKey.getInstance();
key.setAPIKey("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");
super.onCreate(savedInstanceState);
}
public void setup() {
// create a trackable from a bundled image.
ARImageTrackable wavesTrackable = new ARImageTrackable("waves");
wavesTrackable.loadFromAsset("waves.png");
// create video texture.
ARVideoTexture videoTexture = new ARVideoTexture();
videoTexture.loadFromAsset("waves.mp4");
ARVideoNode videoNode = new ARVideoNode(videoTexture);
// add video to the waves trackable.
wavesTrackable.getWorld().addChild(videoNode);
// load a set of trackables from a bundled file.
ARTrackableSet trackableSet = new ARTrackableSet();
trackableSet.loadFromAsset("demo.KARMarker");
ARImageTracker tracker = ARImageTracker.getInstance();
// add our trackables to the tracker.
tracker.addTrackableSet(trackableSet);
tracker.addTrackable(wavesTrackable);
// create an image node.
ARImageTrackable legoTrackable = tracker.findTrackable("lego");
ARImageNode imageNode = new ARImageNode("BatmanLegoMovie.png");
// make it smaller.
imageNode.scaleBy(0.5f, 0.5f, 0.5f);
// add it to the lego trackable.
legoTrackable.getWorld().addChild(imageNode);
}
@Override
public void didDetect(ARImageTrackable trackable) {
Log.i("KudanSamples", "detected " + trackable.getName());
}
@Override
public void didTrack(ARImageTrackable trackable) {
Log.i("KudanSamples", "tracked");
}
@Override
public void didLose(ARImageTrackable trackable) {
Log.i("KudanSamples", "lost " + trackable.getName());
}
}
我移動資產/的SD卡/標記/資產/和代替
trackableSet.loadFromAsset("demo.KARMarker");
我使用的方法：
trackableSet.loadFromPath("sdcard/marker/demo.KARMarker");
A LSO許可使用：
