我正在开发一款音乐播放器应用程序。除了应用程序突然死亡外,一切都正常。有时候这种情况发生在应用程序启动后,有时候是在长时间运行后。有时候一切正常,应用程序没有崩溃。我观察日志以了解是什么原因导致应用程序崩溃,并找到了以下内容:
11-02 16:39:39.293: A/libc(3556): @@@ ABORTING: INVALID HEAP ADDRESS IN dlfree
11-02 16:39:39.293: A/libc(3556): Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1)
以下是完整的日志,当应用程序崩溃时在logcat中找到的内容:
