在執行程式的時候出現了上述異常，導致程式崩潰。檢視異常資訊，沒有丟擲的java異常，只有這些資訊。01-17 16:47:24.648 9269-9269/com.face.imageclassify A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 9269 (l.imageclassify) [ 01-17 16:47:24.648 396: 396 W/ ] debuggerd: handling request: pid=9269 uid=10265 gid=10265 tid=9269 01-17 16:47:24.649 1843-2091/?

檢視上述異常資訊，可以看到是libfaceall.so檔案中的FaceCompare_nativeCompare方法出了問題。
後來查到是java程式碼呼叫.so檔案裡的本地方法時，java程式碼在給本地方法傳引數時傳的值為空，導致本地方法空指標，出現了上述問題。在java程式碼往本地方法傳引數時先判斷值是否為空，問題解決。
