我正在开发一个安卓应用程序。我在其中获取用户照片图像(5 张图像)(使用带有面部检测的opencv2.4.2相机)并使用 Web 服务将其保存到服务器中的数据库中。为此,我使用 Opencv2.4.2 人脸检测示例,Ksoap2用于 Web 服务。在我的 android模拟器设备(android 4.0.4)应用程序中工作正常。但是当我检查另一台设备(android 4.0.3)时,它会抛出"Unfortunately, Myapp has stopped"。我在下面附上了我的日志文件。我不知道是什么问题。你能给我关于这方面的建议吗?

你段错误。这意味着您访问了您没有合法访问权限的内存。该地址非常低,因此几乎可以肯定是由于取消引用空指针或尝试访问空数组。实际的崩溃发生在 dalvik 堆中。因此,您以某种方式将 null 传递给堆或覆盖了堆正在使用的某些内容。

这很可能是通过 JNI 调用覆盖 dalvik 认为已释放并已重用的内存而发生的。
