開頭會告訴你，是哪一個包ANR 了。因此，之後搜索ANR 能夠在log 裏面搜索：java
Cmd line: com.oppo.reader
後面替換成你的包名。android
第一步：查看主線程
"main" prio=5 tid=1 Blocked | group="main" sCount=1 dsCount=0 flags=1 obj=0x71ebca68 self=0xe6c0f000 | sysTid=20358 nice=-10 cgrp=default sched=0/0 handle=0xea9254a4 | state=S schedstat=( 2882074832 469149273 2373 ) utm=241 stm=47 core=1 HZ=100 | stack=0xff789000-0xff78b000 stackSize=8MB | held mutexes= at com.zhangyue.iReader.DB.DBAdapter.execSQL(SourceFile:2512) - waiting to lock <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) held by thread 66 at com.zhangyue.iReader.DB.DBAdapter.queryBookIDWithoutPath(SourceFile:1497) at com.zhangyue.iReader.read.ui.BookBrowserFragment.u(SourceFile:1223) at com.zhangyue.iReader.read.ui.BookBrowserFragment.U(SourceFile:368) at com.zhangyue.iReader.read.ui.cc.run(SourceFile:3098) at android.os.Handler.handleCallback(Handler.java:790) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:198) at android.app.ActivityThread.main(ActivityThread.java:7038) at java.lang.reflect.Method.invoke(Native method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:519) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:836)
- waiting to lock <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) held by thread 66
他說，在等待一個鎖，0x08d75003。 你能夠在trace 裏面搜索這個字符，或者後面說，held by thread 66，那就搜索線程66web
tid=66
第二步：找到線程66
"OkHttp https://icloud.zhangyue.com/..." prio=5 tid=66 Native | group="main" sCount=1 dsCount=0 flags=1 obj=0x133c0a30 self=0xc4ca9200 | sysTid=21822 nice=0 cgrp=default sched=0/0 handle=0xbe396970 | state=S schedstat=( 14565089915 55131141 764 ) utm=1423 stm=33 core=2 HZ=100 | stack=0xbe294000-0xbe296000 stackSize=1038KB | held mutexes= kernel: (couldn't read /proc/self/task/21822/stack) native: #00 pc 00018e20 /system/lib/libc.so (syscall+28) native: #01 pc 000b79d1 /system/lib/libart.so (art::ConditionVariable::WaitHoldingLocks(art::Thread*)+80) native: #02 pc 003e2949 /system/lib/libart.so (art::GoToRunnable(art::Thread*)+300) native: #03 pc 003e27ed /system/lib/libart.so (art::JniMethodEnd(unsigned int, art::Thread*)+8) native: #04 pc 00404d45 /system/framework/arm/boot-framework.oat (Java_android_database_sqlite_SQLiteConnection_nativeExecuteForChangedRowCount__JJ+132) at android.database.sqlite.SQLiteConnection.nativeExecuteForChangedRowCount(Native method) at android.database.sqlite.SQLiteConnection.executeForChangedRowCount(SQLiteConnection.java:748) at android.database.sqlite.SQLiteSession.executeForChangedRowCount(SQLiteSession.java:754) at android.database.sqlite.SQLiteStatement.executeUpdateDelete(SQLiteStatement.java:64) at android.database.sqlite.SQLiteDatabase.updateWithOnConflict(SQLiteDatabase.java:1658) at android.database.sqlite.SQLiteDatabase.update(SQLiteDatabase.java:1604) at com.zhangyue.iReader.DB.a.update(SourceFile:129) at com.zhangyue.iReader.DB.DBAdapter.update(SourceFile:4224) at dt.d.b(SourceFile:112) at com.zhangyue.iReader.DB.DBAdapter.updateHighLightByPostion(SourceFile:1657) at df.t.b(SourceFile:269) - locked <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) at df.t.a(SourceFile:66) at df.al.a(SourceFile:118) at df.am.onHttpEvent(SourceFile:88) at com.zhangyue.net.p$b.onHttpEvent(SourceFile:138) at com.zhangyue.net.a.a(SourceFile:796) at com.zhangyue.net.a.a(SourceFile:63) at com.zhangyue.net.c.onResponse(SourceFile:698) at okhttp3.RealCall$AsyncCall.execute(SourceFile:153) at okhttp3.internal.NamedRunnable.run(SourceFile:32) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636) at java.lang.Thread.run(Thread.java:764)
問下了同事， - locked <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter) 表示，從這行的堆棧開始，進入synchronized 代碼塊。（至因而不是，能夠本身去獲取堆棧，嘗試下。）
那麼，也就是在這裏，子線程執行代碼，佔用了 - locked <0x08d75003> (a com.zhangyue.iReader.DB.DBAdapter)這個鎖。sql
第三步：處理
怎麼處理呢？app
- 把沒有用的鎖，去掉。程序裏面不要隨意的加鎖
- 咱們這裏是由於一大坨代碼，都寫在了執行事務裏，致使，執行事務的時候，佔用了SQLite 連接。致使主線程拿不到SQLite 的鎖。
其餘技巧
1.若是你以爲是某一塊代碼執行時間過長致使ANR,那麼能夠把這一塊代碼換成下面這個，看看會不會ANR.composer
long begin = System.currentTimeMillis();
while(System.currentTimeMillis() - begin < 1000 * 60 * 10){
a = 50;
DBAdapter.getInstance().queryALLBook();
}
上面這塊代碼，會執行10分鐘。裏面不停的執行SQL 操做。oop
