android ANR产生原因和解决办法【转】
ANR (Application Not Responding)
第一：什么会引发ANR？
1.在5秒内没有响应输入的事件（例如，按键按下，屏幕触摸）
2.BroadcastReceiver在10秒内没有执行完毕
造成以上两点的原因有很多，比如在主线程中做了非常耗时的操作，比如说是下载，io异常等。
第二：如何避免ANR？
1、运行在主线程里的任何方法都尽可能少做事情。特别是，Activity应该在它的关键生命周期方法（如onCreate()和onResume()）里尽可能少的去做创建操作。（可以采用重新开启子线程的方式，然后使用Handler+Message的方式做一些操作，比如更新主线程中的ui等）
2、应用程序应该避免在BroadcastReceiver里做耗时的操作或计算。但不再是在子线程里做这些任务（因为 BroadcastReceiver的生命周期短），替代的是，如果响应Intent广播需要执行一个耗时的动作的话，应用程序应该启动一个 Service。（此处需要注意的是可以在广播接受者中启动Service，但是却不可以在Service中启动broadcasereciver,关于原因后续会有介绍，此处不是本文重点）
3、避免在Intent Receiver里启动一个Activity，因为它会创建一个新的画面，并从当前用户正在运行的程序上抢夺焦点。如果你的应用程序在响应Intent广 播时需要向用户展示什么，你应该使用Notification Manager来实现。
总结：anr异常也是在程序中自己经常遇到的问题，主要的解决办法自己最常用的就是不要在主线程中做耗时的操作，而应放在子线程中来实现，比如采用Handler+mesage的方式，或者是有时候需要做一些和网络相互交互的耗时操作就采用asyntask异步任务的方式（它的底层其实Handler+mesage有所区别的是它是线程池）等，在主线程中更新UI。
下面一起来分析下错误吧，第一行为出错的时间，第二行都会写上发生ANR的packageName，下文是com.android.systemui这个包，里面的部分线程出了问题，通过下面的的xxx方法以及对应的java文件，后面的数字为xxx.java文件的第几行，是不是很方便呢?

二：ANR的常见类型
ANR一般有三种类型：
1：KeyDispatchTimeout(5 seconds) --主要类型
按键或触摸事件在特定时间内无响应
2：BroadcastTimeout(10 seconds)
BroadcastReceiver在特定时间内无法处理完成
3：ServiceTimeout(20 seconds) --小概率类型
Service在特定的时间内无法处理完成
三：KeyDispatchTimeout
Akey or touch event was not dispatched within the specified time（按键或触摸事件在特定时间内无响应）
具体的超时时间的定义在framework下的
ActivityManagerService.java
//How long we wait until we timeout on key dispatching.
staticfinal int KEY_DISPATCHING_TIMEOUT = 5*1000
四：为什么会超时呢？
超时时间的计数一般是从按键分发给app开始。超时的原因一般有两种：
(1)当前的事件没有机会得到处理（即UI线程正在处理前一个事件，没有及时的完成或者looper被某种原因阻塞住了）
(2)当前的事件正在处理，但没有及时完成
五：如何避免KeyDispatchTimeout
1：UI线程尽量只做跟UI相关的工作
2：耗时的工作（比如数据库操作，I/O，连接网络或者别的有可能阻碍UI线程的操作）把它放入单独的线程处理
3：尽量用Handler来处理UIthread和别的thread之间的交互
六：UI线程
说了那么多的UI线程，那么哪些属于UI线程呢？
UI线程主要包括如下：
Activity:onCreate(), onResume(), onDestroy(), onKeyDown(), onClick(),etc
AsyncTask: onPreExecute(), onProgressUpdate(), onPostExecute(), onCancel,etc
Mainthread handler: handleMessage(), post*(runnable r), etc
other
七:如何去分析ANR
先看个LOG:

04-0113:12:15.872 E/ActivityManager( 220): 32%TOTAL: 28% user + 3.7% kernel
从LOG可以看出ANR的类型，CPU的使用情况，如果CPU使用量接近100%，说明当前设备很忙，有可能是CPU饥饿导致了ANR
如果CPU使用量很少，说明主线程被BLOCK了
如果IOwait很高，说明ANR有可能是主线程在进行I/O操作造成的
除了看LOG，解决ANR还得需要trace.txt文件，
如何获取呢？可以用如下命令获取
$chmod 777 /data/anr
$rm /data/anr/traces.txt
$ps
$kill -3PID
adbpull data/anr/traces.txt ./mytraces.txt
从trace.txt文件，看到最多的是如下的信息：
-----pid 21404 at 2011-04-0113:12:14 -----

说明主线程在等待下条消息进入消息队列
八：Thread状态
ThreadState (defined at “dalvik/vm/thread.h “)
THREAD_UNDEFINED = -1, /* makes enum compatible with int32_t */
THREAD_ZOMBIE = 0, /* TERMINATED */
THREAD_RUNNING = 1, /* RUNNABLE or running now */
THREAD_TIMED_WAIT = 2, /* TIMED_WAITING in Object.wait() */
THREAD_MONITOR = 3, /* BLOCKED on a monitor */
THREAD_WAIT = 4, /* WAITING in Object.wait() */
THREAD_INITIALIZING= 5, /* allocated, not yet running */
THREAD_STARTING = 6, /* started, not yet on thread list */
THREAD_NATIVE = 7, /* off in a JNI native method */
THREAD_VMWAIT = 8, /* waiting on a VM resource */
THREAD_SUSPENDED = 9, /* suspended, usually by GC or debugger */
九：如何调查并解决ANR
1：首先分析log
2: 从trace.txt文件查看调用stack.
3: 看代码
4：仔细查看ANR的成因（iowait?block?memoryleak?）

原因：IOWait很高，说明当前系统在忙于I/O，因此数据库操作被阻塞
原来：
finalMessagemessage=Message.restoreMessageWithId(mProviderContext,messageId);if(message==null){
return;
}
Accountaccount=Account.restoreAccountWithId(mProviderContext,message.mAccountKey);
if(account==null){
return;//isMessagingController returns false for null, but let's make itclear.
}
if(isMessagingController(account)){
new Thread(){
@Override
public void run(){
mLegacyController.processPendingActions(message.mAccountKey);
}
}.start();
}
解决后：
newThread() {
finalMessagemessage=Message.restoreMessageWithId(mProviderContext,messageId);
if(message==null){
return;
}
Accountaccount=Account.restoreAccountWithId(mProviderContext,message.mAccountKey);
if(account==null){
return;//isMessagingController returns false for null, but let's make itclear.
}
if(isMessagingController(account)) {
mLegacyController.processPendingActions(message.mAccountKey);
}
}.start();
