adb download file to /system
这几天折腾个feature，需要下载android.policy.jar到/system/framework
操作命令如下
显示fs信息
$ adb shell mount rootfs / rootfs ro,relatime 0 0 tmpfs /dev tmpfs rw,relatime,size=182108k,nr_inodes=45527,mode=755 0 0 devpts /dev/pts devpts rw,relatime,mode=600 0 0 proc /proc proc rw,relatime 0 0 sysfs /sys sysfs rw,relatime 0 0 none /acct cgroup rw,relatime,cpuacct 0 0 tmpfs /mnt/asec tmpfs rw,relatime,size=182108k,nr_inodes=45527,mode=755,gid=1000 0 0 tmpfs /mnt/obb tmpfs rw,relatime,size=182108k,nr_inodes=45527,mode=755,gid=1000 0 0 tmpfs /mnt/usb tmpfs rw,relatime,size=182108k,nr_inodes=45527,mode=755,gid=1000 0 0 none /dev/cpuctl cgroup rw,relatime,cpu 0 0 /dev/block/mmcblk0p16 /system ext4 ro,relatime,barrier=1,data=ordered 0 0 /dev/block/mmcblk0p17 /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc 0 0 /dev/block/mmcblk0p14 /persist ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0 /dev/block/mmcblk0p15 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0修改/system目录的属性
$ adb shell mount -o remount /dev/block/mmcb1k0p16 /system
或者
adb remount
现在/system目录的属性应该是rw了
/dev/block/mmcblk0p16 /system ext4 rw,relatime,barrier=1,data=ordered 0 0下载android.policy.jar到/system/framework目录
$ adb push android.policy.jar /system/framework/android.policy.jar 2299 KB/s (183975 bytes in 0.078s)更改文件属性
$ adb shell chmod 644 /system/framework/android.policy.jar
然后重启手机
$ adb reboot
另外添加google map支持需要下载两个文件
com.google.android.maps.jar com.google.android.maps.xml
com.google.android.maps.jar到/system/framework
com.google.android.maps.xml到/system/etc/permissions
