Question

我在libc中的应用程序崩溃了。我不知道原因，如果有人知道这次崩溃，请帮助我。

我在网站上获得了这些信息，但我没有任何共享资源（除了一个.so文件作为库），这并没有解决我的问题。

Answer 1

您可以使用addr2line工具更好地了解错误的位置。你可以这样做：

arm-linux-androideabi-addr2line -e libc.so -C 0005d050

如果你有一部开发电话，strace工具也可以提供一些见解。

Answer 2

感谢您的支持。实际上在我的代码中，我正在进行字节到短转换，这会破坏堆。即使分配了足够的内存，我也不知道它是如何被破坏的。在我将此字节移动到解码器中的原生层的短转换后，我现在没有崩溃。

认为它可以帮助你们。所以，结论不仅仅是本机的，即使在java层的内存中也存在任何损坏，我正在使用libc进行转储。即使问题出在Java层，这也误导我专注于原生层。

谢谢＆amp;问候，
