and what are the steps listed to change the boot storage from eMMC to SD? 1 Kudo Reply 02-26-2015 12:57 PM 1,466 Views AlanSouza Contributor III Well, seems like I was missing something applying the patch so I've modified the file /android_source_folder/device/fs...
“sdcard0”表示第一个sd卡(若有外置sd卡,那会多一个 /storage/sdcard1) /sdcard 软连接会指向 /storage/sdcard0 ,此时/mnt/sdcard 也是个软连接,会指向/storage/sdcard0。 因此/storage/sdcard0才是最终源头,/sdcard、/mnt/sdcard是指向它的一个软连接而已。 如果你通过otg线接U盘,会被挂载到 /stor...

在4.1里,同样也会使用fuse技术,/dev/fuse 会被同时挂载到/storage/sdcard0 目录,这个sdcard0表示第一个sd卡(如果有外置sd卡,那会多一个 /storage/sdcard1,比如我的xoom), /sdcard 软连接会指向 /storage/sdcard0 ,此时/mnt/sdcard 也是个软连接,会指向/storage/sdcard0。
这是引用路径,别担心。打开你的ddms File Explorer 你可以在你的mnt/sdcard后面看到一列info列 里面写的就是类似于/storage/emulated/0/这个东西 然后你可以在你的File Explorer中找到storage文件夹,下面就会有emulated,然后下面会有0 其实都是一样的 ...
