pm 在android 代码中的外置：

frameworks\base\cmds\pm

Android.mk 的解析：

3LOCAL_PATH:= $(call my-dir)4include $(CLEAR_VARS)56LOCAL_SRC_FILES := $(call all-subdir-java-files)7LOCAL_MODULE := pm8include $(BUILD_JAVA_LIBRARY) //pm.jar编译出91011include $(CLEAR_VARS)12ALL_PREBUILT += $(TARGET_OUT)/bin/pm13$(TARGET_OUT)/bin/pm : $(LOCAL_PATH)/pm | $(ACP) //拷贝pm 命令为/system/bin/pm14$(transform-prebuilt-to-target)15

pm 命令代码为

1# Script to start "pm" on the device, which has a very rudimentary2# shell.3#4base=/system5export CLASSPATH=$base/framework/pm.jar6exec app_process $base/bin com.android.commands.pm.Pm "$@"7

上面代码中调用pm.jar 中的Pm 静态方法，传入$@ 参数，执行apk 的安装流程。
