android - 不幸的是，应用程序停止了代码名称与 Paypal 集成

Question

在原生接口(interface)实现类中编写如下代码:

    return "test";
}
private void sendAuthorizationToServer(PayPalAuthorization authorization) {

}
public void onDestroy() {


}
public boolean isSupported() {
    return false;
}

}

从主类调用:

 MyNative my = (MyNative)NativeLookup.create(MyNative.class);
        if(my!= null){
          String aa =my.payPalTest();
          System.out.println("result::" + aa);
            System.out.println("paypalInt" + my.toString());
        }

代码构建成功，但是当我尝试从 android 移动设备访问它时，出现错误:

很遗憾已经停止了。如何解决问题

这意味着你有一个未捕获的异常，用电缆连接你的设备并打开 android ddms 来查看跟踪和日志
