写回答
从提供的日志中，我看到了以下错误：
1、启用时发生晚期enablement错误: - Xcheck:jni。可能的原因是因为你的应用程序依赖于其他库或框架，而这些库或框架还没有被正确启用。
2、在runtime_flags中出现了未知的bits set。这可能是由于一些其他问题导致的，例如某些库或框架没有正确配置。
3、启用了unexpected CPU variant。这可能是由于一些编译错误或优化选项导致的，也可能是因为一些特殊的应用场景导致的。
4、avc: denied { write } for name="property_service" dev="tmpfs" ino=6969 scontext=u:r:untrusted_app:s0:c137,c256,c512,c768 tcontext=u:object_r:property_socket:s0 tclass=sock_file permissive=0。这个错误可能是由于你的应用程序尝试访问一个不存在的文件或目录，或者尝试写入一个不存在的文件。
5、libc: Unable to set property "qemu.gles" to "1": connection failed; errno=13 (Permission denied)。这个错误可能是由于你的应用程序尝试访问一个不存在的文件或目录，或者尝试写入一个不存在的文件。
