Android的安装具有写权限的文件系统 [英] Android mount the filesystem with write permission

问题描述

我使用未持有 sqlite3的上的Andr​​oid设备，所以我想以推它的设备后，拉从AVD荷兰国际集团吧。

The Android device I am using does not hold sqlite3 on it, so i thought to push it to the device after pulling it from the AVD.

我没有问题，从AVD拉它，虽然我不能推到设备上，因为我需要启用写入权限。我试图按照​​ sqlite3的：没有发现

I had no problem pulling it from the AVD, though I cannot push it to the device since I need to enable a write permission. I tried to follow sqlite3: not found

我尝试了以下

$ adb -d shell
$ mount
mount
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,relatime,mode=111 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,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/usb tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /app-cache tmpfs rw,relatime,size=7168k 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/mmcblk0p9 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p7 /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered
/dev/block/mmcblk0p1 /efs ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0
nil /sys/kernel/debug debugfs rw,relatime 0 0
/dev/block/mmcblk0p10 /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered,
/dev/block/mmcblk0p4 /mnt/.lfs j4fs rw,relatime 0 0
/dev/block/vold/179:11 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,noatime,n
epage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro,discard 0

我跟着此链接并尝试挂载文件系统的内容，但我有一个允许的错误。

I followed this link and tried to mount the filesystem as follows but I got a permission error.

$ mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p9 /system
mount: Operation not permitted 

任何需要的是什么来是为了做推 sqlite3的成的Adroid设备调试原因的线索？

Any clue what is needed to be done in order to push sqlite3 into an Adroid device for debugging reasons?

推荐答案

解决方法很简单。要重新安装已安装的系统，你需要有root权限。做一个苏。您将进入根模式。然后运行下面的命令。它会工作，我做了许多次。

Solution is simple. To remount a mounted system you need to have root privileges. Do an su. You will enter root mode. Then run the below command. It will work, I did it many a times.

因此​​，这里的步骤：

So here are the steps:

 adb shell 
 su
 mount -o rw,remount -t ext4 /system

编辑：找到一个更好的解决方案。

Found a better solution

从主机（Linux或Windows PC），执行以下命令。

From host machine(Linux or windows PC), execute the following commands.

>> adb root
>> adb remount

再登在默认情况下重新挂载/系统分区与RW，如果你拥有的权限。

remount will by default remount the /system partition with rw, if you have the permissions.

注意1：：要做到苏或亚行根，您的设备必须植根并有苏可执行文件就可以了。当你做一个苏，如果它是正确执行，你的终端提示符将从 $ 更改为＃。谢谢..

Note 1: To do su or adb root, your device must be rooted and have su executable on it. When you do an su, if it is executed properly, your terminal prompt will change from $ to #. Thanks..

注意2： 在最近的手机，很少有宏碁和三星的，我知道，安全性有所收紧，甚至生根的电话后，亚行重新装入是行不通的。由于我知道，有没有解决方案，适用于它为止。

Note 2: In recent mobiles, few of acer and samsung that i know, Security has been tightened, and even after rooting the phone, adb remount wouldn't work. As of i know, there is no solution available for it so far.
