Android 命令：实现启动一个apk

1、产生背景：为了调试方便，常常希望通过知道apk的路径，直接去启动它，所以就写了这个命令2、使用方法：adb push launch /data/

adb push /data/

adb shell

launch复制代码其实放到/system/下面也可以，把jar包放到/system/framework/下面，把launch命令放到/system/bin/下面，然后adb shell 进去，直接执行launch就可以了，传入apk的路径参数。3、eg：launch /data/app/复制代码4、代码：：

# Copyright 2008 The Android Open Source Project #

LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS)

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_MODULE := launch include

$(BUILD_JAVA_LIBRARY)

launch：

# Script to start "launch" on the device, which has a very

rudimentary # shell. # export

CLASSPATH=/system/framework/ exec

app_process /system/bin

$* #export

CLASSPATH=/data/ #exec app_process /data/

$*
