Question

我的应用程序使用ACRA进行错误报告，我的设备中有一些报告错误：只能使用较低的16位来处理requestCode.Google显示使用startActivityForResult时出现此错误，但我已经我几次搜索了我的代码而且我没有在任何地方打电话。

我很困惑，并且想知道这对用户有何影响（有趣的是，Crash Reports测试版没有显示任何错误）。

其他人遇到这个？

有人可以帮我吗？

来自FragmentActivity源代码：

/**
* Modifies the standard behavior to allow results to be delivered to fragments.
* This imposes a restriction that requestCode be <= 0xffff.
*/
@Override
public void startActivityForResult(Intent intent, int requestCode) {
    if (requestCode != -1 && (requestCode&0xffff0000) != 0) {
        throw new IllegalArgumentException("Can only use lower 16 bits for requestCode");
    }
    super.startActivityForResult(intent, requestCode);
}

您的请求代码似乎只能达到0xffff，这对于我们基地10名痴迷的人来说会转化为65535。
