Android开发，往虚拟机里写文件，报这个错，没有权限的问题，百度都是英文（写成中文方便百度收录^_^），差点找不到解决方法网址链接：

就是在AndroidManifest.xml文件中加入一句话。

<code style="padding: 0px; border-width: 0px; margin: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; vertical-align: baseline; background-color: rgb(238, 238, 238);"><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"><manifest></span></code>

<code style="padding: 0px; border-width: 0px; margin: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; vertical-align: baseline; background-color: rgb(238, 238, 238);"><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"></span></code><pre class="default prettyprint" name="code" style="white-space: pre-wrap; word-wrap: break-word; padding: 5px; border-width: 0px; overflow: auto; margin-top: 0px; width: auto; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; margin-bottom: 10px; max-height: 600px; vertical-align: baseline;"><code style="padding: 0px; border-width: 0px; margin: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; vertical-align: baseline; background-color: rgb(238, 238, 238);"><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"><application></span></code>

……

<code style="padding: 0px; border-width: 0px; margin: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; vertical-align: baseline; background-color: rgb(238, 238, 238);"><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"></application></span><span class="pln" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;">    </span><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"><uses-permission</span><span class="pln" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"> </span><span class="atn" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;">android:name</span><span class="pun" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;">=</span><span class="atv" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;">"android.permission.WRITE_EXTERNAL_STORAGE"</span><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;">/></span><span class="pln" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"></span><span class="tag" style="padding: 0px; border-width: 0px; margin: 0px; vertical-align: baseline; background-color: transparent;"></manifest></span></code>

还有就是open failed: EISDIR (Is a directory)这个很明显，你写入的路径是个文件夹，把路径“……/……/”最后一个“/”去掉，或者再添加一个文件名。
