blocks|key|600678|text|您可以使用openFileOutput访问内部存储。有关更多信息，请阅读documentation+on+internal+storage。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|600679|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/content/Context.html|1|http://developer.android.com/guide/topics/data/data-storage.html#filesInternal^0|5|E|5|E|0|10|X|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]|$9|V|A|W|1|X]]|E|$]]|$1|F|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]|N|$5|I|J|K|E|$L|O]]]]

You can use <a href="http://developer.android.com/reference/android/content/Context.html" rel="nofollow"><code>openFileOutput</code></a> to get an access to the internal storage. For more info, you should read the <a href="http://developer.android.com/guide/topics/data/data-storage.html#filesInternal" rel="nofollow">documentation on internal storage</a>.

blocks|key|1652090|text|首先，您应该通过检查getExternalStorageState()来检查外部存储(SD卡)是否可用并准备好写入。点击此处阅读更多信息：http://developer.android.com/guide/topics/data/data-storage.html#filesExternal|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1652091|然后，如果SD卡不可用，您可以写入内部存储。在这里阅读更多关于如何写和读的例子：http://developer.android.com/guide/topics/data/data-storage.html#filesInternal|1652092|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/guide/topics/data/data-storage.html#filesExternal|1|http://developer.android.com/guide/topics/data/data-storage.html#filesInternal^0|1X|26|0|0|14|26|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

First you should check if External Storage (SD card) is available and ready to write to by checking getExternalStorageState().
Read more here: <a href="http://developer.android.com/guide/topics/data/data-storage.html#filesExternal" rel="nofollow">http://developer.android.com/guide/topics/data/data-storage.html#filesExternal</a>

Then if SD card not available you can write to internal storage.

blocks|key|4270340|text|通过改变得到了它|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4270341|Environment.getExternalStorageDirectory()+%2B+"/Message.xml"|code-block|syntax|javascript|4270342|转到|4270343|Environment.getDataDirectory()+%2B+"/data/com.companyname.appname/files/Message.xml"|4270344|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]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Got it by changing

<pre><code>Environment.getExternalStorageDirectory() + "/Message.xml"
</code></pre>

into

<pre><code>Environment.getDataDirectory() + "/data/com.companyname.appname/files/Message.xml"
</code></pre>

In my app I save an XML file to the user's SD card by doing <code>File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/Message.xml");</code>

But not all users have SD-cards in their phone and therefore my app is likely to crash.

How must I change my File creating method in order to save the file to the phone's memory instead of the SD-card?

Also, how must I change the loading of the file? (currently: <code>new InputSource(new FileInputStream(Environment.getExternalStorageDirectory() + "/Message.xml"))</code>)

EDIT: I don't think you got the question right. I know the Data-Storage page of the Android Docs and I've read it. I just want to know how I should it adjust it to match my current way of saving and loading a file.

Saving file to phone instead of SD card

在我的应用程序中，我通过执行File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/Message.xml");将XML文件保存到用户的SD卡中但并不是所有用户的手机都有SD卡，因此我的应用程序可能会崩溃。如何更改我的文件创建方法...
