Android :: Creating A Hidden Partition

How to "make partitions invisible and provide access to few applications only on this invisible partition"
I'm not sure if this needs to be in the Support/TroubleShooting section or in the All Things Root Section. Mods, feel free to move. Anyone know where I can get some detailed instructions for creating a SD Ext 4 partition? Is this something easy to do in Windows? I'm running Ubuntu mainly so if there are ways to do it in there that would be good too.

I have deleted text messages, cleared cache, deleting emails from inbox and trash etc. I going to get rid of a few apps too, but its a bummer if I cant have many apps due to it affecting memory!
Also I understand that if flash it with the Modaco custom ROM. I can create a swap partition, does this help a lot? Also would I lose quite a lot of the HTC Hero features such as Sense UI for example if I flash it with Modaco?

I have two questions:
1) What is the shell command to manually make android allow the PC to mount androids' (internal) partition as USB-drive? (I cannot think of right keywords to google this one up - )
2) How does android determine which partition is which (i.e. which one to remount for the PC when connecting in "USB storage" mode), beside vold.fstab and init.rc? On android 2.3 that info is not in "framework-res.apk", so where is it? In the partition table itself?
I had switched data partition with internal sdcard partition.
Here's how: Phone had a very small "/data" partition on /dev/block/mmcblk0p21 and large internal "/sdcard" partition on mmcblk0p20
So I reformatted mmcblk0p20 (ex-sdcard partition) into EXT4 and mmcblk0p21 (ex-data partition) into FAT32
Then I changed init.rc to mount mmcblk0p20 as /data type EXT4 and mmcblk0p21 as /sdcard type VFAT (mounting /sdcard was commented out in stock init.rc for some reason). This required modifying my boot image.
I have also set correct partition number in vold.fstab:
[#]dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host[/#]
So basicly I now have a large /data partition and small internal /sdcard. I'm able install up to a gigabyte of APKs and it works fine.
However, when I connect to my PC via USB into "USB Storage" mode, the phone seems to still try to unmount what was previously sdcard partition (/dev/block/mmcblk0p20), instead of what is NOW an sdcard partition (/dev/block/mmcblk0p21) I can still send files to the phone via wi-fi and ADB, but the ability to mount it directly would be nice.
If I accidentally select "erase internal sdcard" from storage menu, that will also most likely erase what is now my /data partition, softbricking the phone. The "factory reset" option will probably only corrupt the sdcard.
I'm have been trying to create a second partition on my sd card using miniTool Partition Wizard.But in the end I never get a 2nd partition but just a smaller first one.My approach is as follows:
insert empty SD card (FAT32, 4GB)
open miniTool Partition Wizard
right click on SD card - "Move/Resize"
choose 1gb for unallocated space after - click ok
right click on 2nd partition and choose "create"
create 2nd partition with FAT32/Ext2/Ext3 (tried all options already) and "primary" and Cluster 4KB - click ok
Apply
Afterwards my SD card is still shown as one partition, but this has just 1gb less capacity then before.Neither the Wizard nor the phone detects the 2nd partition then.
I can't figure what is exactly meaning the Partition Sdcard values in CWM.
I have an i9000, with 8Gb of flash. Some are system reserved. Available is around 6Gb.
When i run CWM, i can partition my sdcard, but i don't see what means the possible values (for 256 to 4096).
This is obviously not ruling the space left on /sdcard mountpoint (i partition to 2048, i still have nearly 6Gb available)... So what exactly means partition sdcard from CWM ??
i can't find an answer, and i dislike, when flashing rom, following commands i don't really master (generally a partition SD 2048 / SWAP 256 or SWAP 0).
I have bought a cheap chinese phone that had a 4g rom. 512mb is mapped to data as p3 and p4 is mapped to internal storage which is 2g.
I have managed to work out how to delete partition4 and extend partition3 as they follow on from each other.
However how do I remove all links to it in the system as it still tries to mount it on boot even though it isn't there.
I have removed the line from vold.fstab and that just crashed the external and internal sdcards and the storage section inside the system settings.
It seems that the hidden files app will not download for me. I have already purchased and cannot get it installed. It seems it is hit or miss on cupcake.

So I wonder how we can use these providers. I know we integrate our own firmware, however, I wonder if we can solver this problem on the current SDK, so that my app can run on all public android system.
View 4 Replies View RelatedI'm fairly new to Android and have gone through the basic tutorials. I thought I'd dig a little deeper and downloaded the source code to some of the "native" Android apps, like IM, Email, Voice Dialer, etc.
In importing the source of these native apps into Eclipse, I found that they reference classes that are not in the 2.1 API, i.e. classes such as android.content.Entity, android.net.http.DomainNameChecker, etc. As a result, I can't compile and play with this code.
So is there is a "hidden" API that the native apps use that is not available to the regular app developers? Is there a "native" SDK I can use to import these classes?

I'm placing the file '.nomedia' into a folder in order to avoid Android's MediaScanner from detecting the media files in the folder. I need to copy this folder (including '.nomedia') from the APK's assets to the SD card (so other apps can make use of these media files, etc.). When I package the APK in Eclipse, it doesn't package the '.nomedia' file. Presumably it's detecting it as a hidden file. Any ideas how to fix this? Is there a secret aapt flag I can use? I'd like to avoid copying the folder and then manually creating a '.nomedia' folder, if possible.

View 2 Replies View RelatedI've got a contextual menu that appears when a button is clicked. This menu has some links and after some seconds is hidden again. The problem is that after the menu has disappeared the links are still there. They are not shown but are clickable and the green border appears. And after some seconds they disappear. I've tryied many ways of hiding the menu: display: none, visibility: hidden, width: 0, height: 0, jquery hide, jquery fadeout... but none worked. Also hidding the links. Does anyone have a idea about what's happening? With the rest of the browsers it works without problem

I tried with setting the value in a textedit and then make it invisible, but the result is that the value is invisible, but the control takes space.

I'm writing a little app that uses GPS coordinates and I have a toast that pops up and displays my current GPS coordinates (and updates them as they change).It works fine but when I close the app the toast remains and covers whatever I do on the homescreen (and continues to update the GPS coordinates).How do I get it to cancel when I close/hide the application?
View 2 Replies View RelatedI recently got some fade in stuff working so that my "loading" view is an ImageView that takes up the whole screen, and then I fade in the main view (a GridView in this case) over the top of it. In the activity creation, I call:

Do I need to do anything in particular to clean up the loading_foo view to reduce the amount of memory my app is using? Any other issues with this approach?

View 3 Replies View RelatedI'm thinking about using a hidden api to turn the screen off in my app. setScreenState from http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/os/Power.java does what I want, but its a hidden API. Does that mean I shouldn't use it? I would think its a fairly stable api.
Currently, I'm setting the screen timeout to 1 millisecond, and then resetting the timeout once the screen turns off. However, android ignores the 1 millisecond and instead it takes about 3 seconds to turn off and sometimes it ignores it completely and doesn't turn off.
Any suggestions?
