SVN操作时，遇到“由于系统缓冲区空间不足或队列已满，不能执行套接字上的操作”提示错误
依据[SVN_ERROR]，查看了电脑socket端口使用情况，发现某一进程大量持有连接，手动杀了该进程，可以正常使用SVN了。

NETSTAT -ano
使用adb install -r重新安装应用时，报[INSTALL_FAILED_MISSING_SHARED_LIBRARY]错误
这是由于在 AndroidManifest.xml 文件中，使用了uses-library属性导致，可以移除该属性或者设置其为false。
如下[MISSING_LIBRARY][USES_LIBRARY]：

3
<uses-library
android:name="com.xxx.xx.xxx"
android:required="false"/>
ListView 中 AdapterView.OnItemClickListener 不会被回调
由于ListView中有CheckBox组件，一直以为是事件分发导致，最后发现ListView未注册监听器。对自己醉了。
关于ListView的子项中有CheckBox组件，只需要把CheckBox设置android:focusable="false"即可，为了更好的处理事件，也做了android:clickable="false"设置。
修改的代码如下：

<CheckBox
android:id="@+id/item_select_checkbox"
android:layout_width="wrap_content"
android:layout_height="52px"
android:focusable="false"
android:clickable="false"
android:button="@drawable/btn_select"
android:gravity="center_vertical"
android:paddingRight="8px"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true" />
[Android] 自定义Notification导致的RemoteServiceException
该问题是由于在RemoteViews布局文件中使用View组件导致，解决文档remote_views_error。
RemoteViews是不支持View的。
