怎么样调用原生Activity?

正在开发一个app，硬件厂商给的SDK要求继承BaseActivity。我直接用原生插件继承WXModule的JSMethod里面 startActivity(),结果出现空白页什么也没有，而且卡死了，只能强制结束。有没有其他办法？

public class BleLockModule extends WXModule  {  

    BleLock bleLock=new BleLock();  
    String address="";  

    @JSMethod(uiThread = true)  
    public void toast(String message,final JSCallback jsCallback){  
        Toast.makeText(mWXSDKInstance.getContext(),message,Toast.LENGTH_LONG).show();  
        JSONObject result = new JSONObject();  
        result.put("data","我是来自原生插件的数据");  
        jsCallback.invoke(result);  

    }  

    @JSMethod(uiThread =true)  
    public void openLock(JSONObject options,final JSCallback jsCallback){  
        //String deviceId=options.getString("deviceId");  
        final Context context = mWXSDKInstance.getContext();  

        Activity activity= (Activity) mWXSDKInstance.getContext();  
        Intent it=new Intent(activity,OpenLocakActivity.class);  
        Bundle bundle =new Bundle();  
        it.putExtras(bundle);  
        it.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP );  
        context.startActivity(it);  
}  
}
