4. 错误： java中引用资源文件的数字未修改完全，将会直接崩溃。
5. 错误： Cause: archive is not a ZIP archive

6. 错误： Error: Program type already present: android.support.v4.app.FragmentActivity$1

7. 安装错误提示： INSTALL_PARSE_FAILED_MANIFEST_MALFORMED
初步原因，包命中存在大写的字母。
但是，为什么，别人的apk包名大写可以安装？

可以解决包名大写问题，但是好还有类名的Com也是大写的（未解决）。
还存在的问题

8. 错误： [drawable-mdpi-v4/ic_launcher] F:\chNet\workspace\hubei\SmartSearch5\app\src\main\res\drawable-mdpi\ic_launcher.png [drawable-mdpi-v4/ic_launcher] F:\chNet\workspace\hubei\SmartSearch5\app\src\main\res\drawable-mdpi-v4\ic_launcher.png: Error: Duplicate resources
   错误原因：资源文件中，两个相同功能的的文件夹下存在两个相同名称的资源，重复了。
   解决办法：删除多余的资源
