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
1"main" prio=5 tid=1 Blocked 2 | group="main" sCount=1 dsCount=0 flags=1 obj=0x71ebca68 self=0xe6c0f000 3 | sysTid=20358 nice=-10 cgrp=default sched=0/0 handle=0xea9254a4 4 | state=S schedstat=( 2882074832 469149273 2373 ) utm=241 stm=47 core=1 HZ=100 5 | stack=0xff789000-0xff78b000 stackSize=8MB 6 | held mutexes= 7 at com.zhangyue.iReader.DB.DBAdapter.execSQL(SourceFile:2512) 8 - waiting to lock <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) held by thread 66 9 at com.zhangyue.iReader.DB.DBAdapter.queryBookIDWithoutPath(SourceFile:1497) 10 at com.zhangyue.iReader.read.ui.BookBrowserFragment.u(SourceFile:1223) 11 at com.zhangyue.iReader.read.ui.BookBrowserFragment.U(SourceFile:368) 12 at com.zhangyue.iReader.read.ui.cc.run(SourceFile:3098) 13 at android.os.Handler.handleCallback(Handler.java:790) 14 at android.os.Handler.dispatchMessage(Handler.java:99) 15 at android.os.Looper.loop(Looper.java:198) 16 at android.app.ActivityThread.main(ActivityThread.java:7038) 17 at java.lang.reflect.Method.invoke(Native method) 18 at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:519) 19 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:836)
- waiting to lock <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) held by thread 66
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.
1 long begin = System.currentTimeMillis(); 2 3 while(System.currentTimeMillis() - begin < 1000 * 60 * 10){ 4 a = 50; 5 DBAdapter.getInstance().queryALLBook(); 6 } 7
上面这块代码，会执行10分钟。里面不停的执行SQL 操作。
