[0]在安卓手机上drawToTexture不能正确返回纹理对象，是HTMLCanvas

浏览器上 是能返回正确值，在layaNative模式出包。手机上调用此方法返回的对象类型不对
  
private _agentTexture: any;
private _agent:Laya.Sprite; 
 
public startDrag(dragCom: Laya.Sprite, touchID: number, sourceData?: any): void {let bounds = dragCom.getSelfBounds();
this._agentTexture = Laya.Sprite.drawToTexture(dragCom,Laya.SpriteConst.TEXTURE,bounds.width, bounds.height, -bounds.x + view.x, -bounds.y + view.y);
this._agent.graphics.drawTexture(this._agentTexture, (this._agent.width - bounds.width) * 0.5, (this._agent.height - bounds.height) * 0.5);
 
}
