该打的地方都打印了。AnyChatCameraHelper 在日志都一个没打印出来。其他的日志都是可以打印的。
正常情况下日志：
07-29 15:00:56.729: E/zhaoxiangji(9864): =====182==line=====
07-29 15:00:58.649: E/zhaoxiangji(9864): =====31====line====
07-29 15:00:58.789: E/zhaoxiangji(9864): =====52==line=====
07-29 15:00:58.789: E/zhaoxiangji(9864): =====56==line=====
07-29 15:00:58.809: E/zhaoxiangji(9864): =====70==line=====
07-29 15:00:59.429: E/zhaoxiangji(9864): =====176==line=====
不正常情况下，一个也打不出来。
麻烦提供下思路。 |
