这个命令与Package有关。且很有用。所以研究之。
0. Usage： usage: pm [list|path|install|uninstall] pm list packages [-f] pm list permission-groups pm list permissions [-g] [-f] [-d] [-u] [GROUP] pm list instrumentation [-f] [TARGET-PACKAGE] pm list features pm path PACKAGE pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH pm uninstall [-k] PACKAGE pm enable PACKAGE_OR_COMPONENT pm disable PACKAGE_OR_COMPONENT pm setInstallLocation [0/auto] [1/internal] [2/external] The list packages command prints all packages. Options: -f: see their associated file. The list permission-groups command prints all known permission groups. The list permissions command prints all known permissions, optionally only those in GROUP. Options: -g: organize by group. -f: print all information. -s: short summary. -d: only list dangerous permissions. -u: list only the permissions users will see. The list instrumentation command prints all instrumentations, or only those that target a specified package. Options: -f: see their associated file. The list features command prints all features of the system. The path command prints the path to the .apk of a package. The install command installs a package to the system. Options: -l: install the package with FORWARD_LOCK. -r: reinstall an exisiting app, keeping its data. -t: allow test .apks to be installed. -i: specify the installer package name. -s: install package on sdcard. -f: install package on internal flash. The uninstall command removes a package from the system. Options: -k: keep the data and cache directories around. after the package removal. The enable and disable commands change the enabled state of a given package or component (written as "package/class"). The getInstallLocation command gets the current install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media The setInstallLocation command changes the default install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media 1. 详细用法 ： 1.1：察看已安装的包： pm list package 此时则显示全部已经安装的包名。 pm list package -f 也显示associated文件所在文件夹(即保存的APK文件) 1.2：察看已知的权限组： pm list permission-groups 1.3：察看全部已知的权限 ： pm list permissions 1.4： 列出全部硬件相关信息 ： pm list features 结果通常类似： feature:reqGlEsVersion=0x20000 feature:android.hardware.bluetooth feature:android.hardware.camera feature:android.hardware.location feature:android.hardware.location.network feature:android.hardware.microphone feature:android.hardware.sensor.accelerometer feature:android.hardware.sensor.compass feature:android.hardware.touchscreen feature:android.hardware.wifi 1.5：列出指定包名的 associated 文件 (APK存档文件) 所在 ： 比如： pm path com.TDiJoy.fane package:/mnt/asec/com.TDiJoy.fane-1/pkg.apk 1.6: 安装APK： pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH PATH 指 APK文件绝对路径和文件名称。 比如： pm install /data/3dijoy_fane.apk 这几个參数非常实用： -r: 安装一个已经安装的APK。保持其数据不变。 -i：指定安装的包名。(没试出来) -s: 安装到SDCard上 。 -f: 安装到内部Flash上。 1.6：卸载APK： pm uninstall 包名。 比如： pm uninstall com.TDiJoy.fane 1.7: 得到和设置缺省安装位置： The getInstallLocation command gets the current install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media The setInstallLocation command changes the default install location 0 [auto]: Let system decide the best location 1 [internal]: Install on internal device storage 2 [external]: Install on external media pm getInstallLocation 得到缺省的安装位置。 设置： pm setInstallLocation <0|1|2> 0: 自己主动。1：内部Flash。
2：扩展存储设备。 实例：怎样在海信2.2 STB上将APK安装到U盘中： Sam首先尝试使用： pm setInstallLocation 2 之后安装之，没实用。 后来做例如以下尝试：
在其他设置->存储设备->制定默认存储设备中选择U盘为默认存储设备。
# pm install -s xxxx.apk
