You can use this as a safe way to stop threads:

You can use <code>safeThread.quitsafely</code> as well.

blocks|key|245249|text|我知道这是一个有点老的问题，但是我在寻找同样的答案时偶然发现了这个问题，并进行了进一步的研究。我不相信目前的答案适用于HandlerThread+(尽管对于正常的线程来说绝对正确)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|245250|HandlerThread有一个内置的quit()和quitSafely(API18)方法来停止线程。https://developer.android.com/reference/android/os/HandlerThread.html#quit()|offset|length|style|CODE|245251|两者之间的区别仅在于队列中的消息是否会在其停止之前被处理。|245252|所以要回答这个问题，很简单：|245253|safeThread.quit();|code-block|syntax|javascript|245254|entityMap|0|LINK|mutability|MUTABLE|url|https://developer.android.com/reference/android/os/HandlerThread.html#quit()^0|0|J|6|Q|A|1F|24|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Z|8|@$D|10|E|11|F|G]|$D|12|E|13|F|G]]|9|@$D|14|E|15|1|16]]|A|$]]|$1|H|3|I|5|6|7|17|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|18|8|@]|9|@]|A|$]]|$1|L|3|M|5|N|7|19|8|@]|9|@]|A|$O|P]]|$1|Q|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|X]]]]

I know it's a somewhat old question, but I stumble across it looking for the same answer and further researching I don't believe the current answer applies very well to HandlerThread (although absolutely correct for normal threads)

HandlerThread have a builtin <code>quit()</code> and <code>quitSafely</code>(API18) methods to stop the thread.
<a href="https://developer.android.com/reference/android/os/HandlerThread.html#quit()">https://developer.android.com/reference/android/os/HandlerThread.html#quit()</a>

the difference between the two is only if the messages in queue will be processed before it stops or not.

so to answer, it's as simple as: 

<pre><code>safeThread.quit();
</code></pre>

blocks|key|4286091|text|如果像这样启动线程：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4286092|HandlerThread+thread+=+new+HandlerThread("MyHandlerThread");
thread.start();|code-block|syntax|javascript|4286093|阻止它的最安全的方法是：|4286094|thread.quitSafely();|4286095|quitSafely可确保在线程停止之前处理所有挂起的消息。|offset|length|style|BOLD|4286096|注意:我最初的回答包括一个对thread.join的额外调用，但我发现join调用在quitSafely之后使用时不能可靠地释放。|4286097|entityMap^0|0|0|0|0|0|A|0|E|B|Z|4|16|A|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|Y|8|@$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|11|8|@$M|12|N|13|O|P]|$M|14|N|15|O|P]|$M|16|N|17|O|P]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|18|8|@]|9|@]|A|$]]]|T|$]]

If you start the thread like this:

<pre><code>HandlerThread thread = new HandlerThread("MyHandlerThread");
thread.start();
</code></pre>

The safest way to stop it would be:

<pre><code>thread.quitSafely();
</code></pre>

quitSafely ensures that all pending messages are processed before the thread stops. 

Note: My original answer included an additional call to thread.join, but I found the join call does not release reliably when used after quitSafely.

blocks|key|4286127|text|我一直在关注这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4286128|if+(safeHandler!=+null)+{
+++++final+Looper+looper+=+safeHandler.getLooper();

I have been following this :

<pre><code>if (safeHandler!= null) {
 final Looper looper = safeHandler.getLooper();
 looper.quitSafely();
 safeHandler = null;
 }
</code></pre>

I always create two handler: one is wraping on main thread, another is wraping on a single thread.

Is this a best method to start and stop these in an Activity lifecycle?

<pre><code>HandlerThread safeThread = null;
Handler safeHandler = null;
Handler handler = null;


@Override
 public void onStart() {

if (safeThread == null) {
 safeThread = new HandlerThread("safeThread");
 safeThread.start();
 safeHandler = new Handler(safeThread.getLooper());
 } else if (safeThread.getState() == Thread.State.NEW) {
 safeThread.start();
 safeHandler = new Handler(safeThread.getLooper());
 } else if (safeThread.getState() == Thread.State.WAITING) {
 safeHandler = new Handler(safeThread.getLooper());
 } else if (safeThread.getState() == Thread.State.TERMINATED) {
 safeThread = null;
 safeThread = new HandlerThread("safeThread");
 safeThread.start();
 safeHandler = new Handler(safeThread.getLooper());
 }
}




protected void onStop() {
 Log.d("x", "onStop is executed");
 safeHandler = null;
 safeThread.quit();
 safeThread.interrupt();
 safeThread = null;
 super.onStop();
 }
</code></pre>

Is this a prefect way to stop handlerthread?
