blocks|key|599936|text|您必须使用API11或更高级别，除非您能找到在提供THREAD_POOL_EXECUTOR实现的早期API级上工作的库。此外，请查看Google是否提供了任何后端口或支持库，以便在API11之前实现此功能。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|599937|entityMap^0|P|K|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

You will have to use API level 11 or higher unless you can find a library that works on an earlier API level that provides the <code>THREAD_POOL_EXECUTOR</code> implementation. Also, check to see if Google provides any backports or support libraries that would allow this to work before API 11.

blocks|key|1834890|text|在清单集API中，这是您希望支持的最低android:minSdkVersion="minimumApiYouNeed"和android:targetSdkVersion="maximumApi"。这是将用于编译代码的api。这样，您将能够执行类似于您在那里编写的内容，如果您曾经编写过不受最低api支持的内容，编辑器将通知您，但如果您进行检查，它将正常工作|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1834891|entityMap^0|J|15|1P|11|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

In the manifest set <code>android:minSdkVersion="minimumApiYouNeed"</code>, this is the lowest api you want to support, and the <code>android:targetSdkVersion="maximumApi"</code>. This is the api that will be used to compile the code. This way you will be able to do things like what you wrote there, if you ever write something that is not supported by the minimum api, the editor will notify you, but it will work well if you do the checking it will work well

This supports Android back to 2.1 (sdk version 7), but compiles the code against sdk version 17 (HoneyComb). You would have to add that tag to your manifest, of course.

<pre><code>&lt;uses-sdk
 android:minSdkVersion="7"
 android:targetSdkVersion="17" /&gt;
</code></pre>

Your project.properties should include this line:

<pre><code># Project target.
target=Google Inc.:Google APIs:17
</code></pre>

blocks|key|3959537|text|假设您的清单中存在以下行|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3959538|<uses-sdk+android:minSdkVersion="8"+android:targetSdkVersion="17"/>|code-block|syntax|javascript|3959539|这意味着您使用的是API-17的特性，但为了确保向后兼容性，您的应用程序可能会在最低API-8+(Froyo)上启动。|3959540|根据您的示例，对API-17或更低版本使用THREAD_POOL_EXECUTOR是可以的。在Froyo设备上运行你的代码也是可以的。因为在这种情况下不会使用THREAD_POOL_EXECUTOR字段。|3959541|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Assume that you line below exists in you manifest

<pre><code>&lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"/&gt;
</code></pre>

This means that you are using features from API-17 but to ensure backwards compatibility your application may start on minimum API-8 (Froyo).

According to your example, using THREAD_POOL_EXECUTOR for API-17 or lower is OK. And running your code with Froyo device is OK too. Because THREAD_POOL_EXECUTOR field will not be used in this case.

I'm developing a Android library and I want to support as many API versions as possible. I have stumbled upon a problem with AsyncTask and found an <a href="https://stackoverflow.com/a/13080444/162003" title="answer">answer</a> here on SO. The proposed code to use is:

<pre><code>if (Build.VERSION.SDK_INT &lt;= Build.VERSION_CODES.GINGERBREAD_MR1) {
 task.execute(params);
} else {
 task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
}
</code></pre>

My question is, how do I include the proposed code AND support lowest possible API level? What API version should I reference? What should I write in the uses-sdk tag inte manifest?

Since the field THREAD_POOL_EXECUTOR in AsyncTask is only available from API level 11. Can this code be compiled to a lower level?

Thanks!
