[REPORT] External 2 internal APK
on my device set onboot checked NOT WORKING. But its working when i push External > Internal button.


[UPDATE]
and after few hours experimenting FOUND a way ! to switch internal as external on boot but this method has a BUG here the BUG list :
1. when we look to settings->storage the storage bar is changing frequently or show full.
2. MTP does not start or in your windows 7 PC on my computer your devices storage not visible.


Here how i do it :
1. Must support init.d script
2. create this script and save to /etc/init.d folder :
Code:
#!/system/bin/sh

if [ -e /dev/block/mmcblk1p1 ]
then
	mount -o bind /data/media /storage/extSdCard 
	mount -t vfat -o umask=0000 /dev/block/mmcblk1p1 /storage/sdcard0
fi;

Note : i suggest the apk method its safer and less frustating creating init.d support for your device

Thanks for the update bro even i have a init script which swaps memory on boot, but if you use that script sometimes phones does not run the media scan which sucks because there is not any way to trigger it manually tried many apps but it didn't worked that's why i posted this method instead of script

if you are using external2internal app then do this restart your phone after the phone is properly booted up don't do anything (i.e don't swap the memory) then run inbuilt music player and then close it after that open camera see if its working fine than close it too, then swap the memory this works most of times and remember after swapping memory media scanner works slower so give it atleast 2 3 mins to update

THE CAMERA CANNOT SAVE the PICTURE I SHOOT

in my previous post is for my script not using external2internal app. For clarification need.

But now i try to disable fuse for sdcard in build.prop to manually trigger media scaner
Code:
persist.fuse_sdcard=false
and i update the init.d script like this
Code:
#!/system/bin/sh

if [ -e /dev/block/mmcblk1p1 ]
then
	mount -o bind,umask=0000 /data/media /storage/extSdCard 
	mount -t vfat -o umask=0000 /dev/block/mmcblk1p1 /storage/sdcard0
else
	mount -o bind,umask=0000 /data/media /storage/sdcard0
fi;


everything seems works perfect with mmc attached and phone srorage as camera save path. BUT has problem without external MMC : camera can save pictures but gallery cannot read the pictures.. the problem is the file owner and file permission on the root explorer it say rw-------- in other word just the owner can view this file. So i try to change permision on that picture and YES it can show on gallery.

Hi I have Panasonic P55 with kitkat 4.4.2 with internal SD and apps do not load on Ext SD.
Is this only solution? Please provide App link as it is no more on Play store

help please
I currently own a Verizon Tablet Ellipsis 8 QTAQZ3 with KOT49H build. Finally a root method that works is KINGROOT. My issue is that I cant swap the internal with external as I am told that even updating UTUBE not enough space. Even with 6 gigabytes left. I have a 64gb class 10 sd card.When I look at dev/block/vold, I see 2 numbers 179:96 and 197:97. The tablet has no recovery made for it (yet). All my apps are on internal storage (partition, I think). I have read that internal and external are both the same. Please clarify, and can you please help.
