Question

您好我正在尝试从链接下面运行示例应用程序

它使用c库来读取pdf文件

但我面临以下错误

java.lang.UnsatisfiedLinkError: Library pdfview2 not found

请告诉我eclipse中是否有其他设置使用本机库

提前致谢

详细日志如下。

请点击链接并按照以下步骤操作。

之前我有相同的错误。现在我得到了输出。这在Android原生编译器中存在问题。

Answer 3

我在Android应用中使用了相同的库。我得到了同样的错误。据我记得的错误是我在Java代码中重命名了包。我还必须重命名C代码中的本机方法以匹配新包。

您是否重命名了包裹？

Answer 4

打开终端/命令提示符。导航到Android项目的根目录。运行ndk-build。有关详细信息，请访问http://developer.android.com/tools/sdk/ndk/index.html
