开头会告诉你，是哪个包ANR 了。所以，以后搜索ANR 可以在log 里面搜索：
Cmd line: com.oppo.reader
后面替换成你的包名。
第一步：查看主线程

他说，在等待一个锁，0x08d75003。 你可以在trace 里面搜索这个字符，或者后面说，held by thread 66，那就搜索线程66
tid=66
第二步：找到线程66

问下了同事， - locked <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) 表示，从这行的堆栈开始，进入synchronized 代码块。（至于是不是，可以自己去获取堆栈，尝试下。）
那么，也就是在这里，子线程执行代码，占用了 - locked <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter)这个锁。
第三步：处理
怎么处理呢？
- 把没有用的锁，去掉。程序里面不要随意的加锁
- 我们这里是因为一大坨代码，都写在了执行事务里，导致，执行事务的时候，占用了SQLite 链接。导致主线程拿不到SQLite 的锁。
其他技巧
1.如果你觉得是某一块代码执行时间过长导致ANR,那么可以把这一块代码换成下面这个，看看会不会ANR.
long begin = System.currentTimeMillis();
while(System.currentTimeMillis() - begin < 1000 * 60 * 10){
a = 50;
DBAdapter.getInstance().queryALLBook();
}
上面这块代码，会执行10分钟。里面不停的执行SQL 操作。
