在Android工程中，设置apk的默认安装位置

在AndroidManifest.xml文件Manifest标签中添加android:installLocation属性

android:installLocation

这个属性设置的是默认安装位置， 共有三个有效值，auto、internalOnly、preferExternal

对应表

auto 表示自动，由系统决定安装位置

internalOnly 安装在手机内存

preferExternal 安装在外部存储中

<table style="margin:0px 0px 0px 30px; padding:0px; border-collapse:collapse; border-spacing:0px; border:1px solid silver; color:rgb(0,0,0); font-family:Verdana,Arial,Helvetica,sans-serif; font-size:14px; line-height:20.8799991607666px; height:117px; width:719px">

   <td style="margin:0px; padding:3px; border:1px solid silver; border-collapse:collapse"> Perfer to be installed on SD card, There is no guarantee that the system will honor this request.

  </tr>

需要注意的问题（如果遇到其他问题，后期进行补充）

需要开启启动的程序，一定要安装到手机内存中，这里就关系到广播消息的先后顺序

开机启动的广播消息BOOT\_COMPLETE早于 SD的启动，如果将程序安装到SD卡，无法接收到开机广播。
