Update on Beta 4
It seems I'm getting mixed results with these betas. I'm not sure why this is occurring, some people have been able to get this working right while others have had a hard time with it.

Currently, I'm rebuilding the entire program. This takes a while because I have to figure out how to pack all these options into the program but make it small enough to where it will run correctly.

I will say that some of the beta features are coming back out...one of them is the search for a partition code. I suspect that code may be leading me into issues with certain platforms, so I'm going back to the 2.7.5.2 method of mounting (mmcblk0p2 or mmcblk1p2).

Also, parts of the code will use Busybox Ash (the only code that won't will be starta2sd, which will still use Bash for the time being). The startup code will definitely use Busybox Ash.

Until then, here are the links to the the last two betas and the last official release:

Version 2.7.5.3 Beta 04 - http://www.darktremor.info/files/a2sd/dtapps2sd-2.7.5.3-beta04-signed.zip
Version 2.7.5.3 Beta 03 - http://www.darktremor.info/files/a2sd/dtapps2sd-2.7.5.3-beta03-signed.zip
Version 2.7.5.2-1 - http://www.darktremor.info/files/a2sd/dtapps2sd-2.7.5.2-1-signed.zip

Beta 04 took longer than I expected to release. I have done major changes to the code:

1. New commands: convert-ext4 - This will convert your EXT3 partition into EXT4. Just a friendly reminder on this command: Not every rom supports EXT4, so it is possible to go into a boot loop if you switch roms. Use with caution.

2. Reworked convert-ext3 (convert-ext4 gets similar code)...now a flag file is set before the reboot (no conversion is done before the reboot). At load time, the conversion is performed. This takes longer in the reboot process and you may think your phone has locked up...wait about five minutes before doing anything with the phone.

3. Repair is rebuilt...now it uses existing commands to repair the setup (reinstall, remove, cachesd, cachepart, nocache, datasd, nodata). Definitely shrinks the code.

4. Added fix_permissions program to the package. This may help with Superuser issues when using the datasd feature. It is used in reinstall, remove, datasd and nodata.

5. a2sd install is back!!! Both a2sd install and a2sd reinstall do the exact same thing.

6. Dalvik heap code has been shrunk and now creates a file called dalvikheap. Actually, the code has been doing this all along (since about 2.7.5.2, I think), but I never put the code in to use the file.

7. Low Memory Killer code has also been shrunk and uses a file caled dtset_lowmem to set the low memory killer parameter.

8. Replaced Busybox PS function with Toolbox PS. The issue with Busybox PS is that it gives a false reading when I look for android.process.acore (which is the main program when the GUI starts up). If that is present, the program thinks you are trying to run Darktremor without any command line parameters. This was because Busybox would report the process was there when, in reality, it wasn't (validated this when my phone was boot looping.) Toolbox's PS reports the correct setting. This should fix the bootlooping issues some people are experiencing.

9. New commands: usedtbusybox and usedefaultbusybox - these commands may help in diagnosing issues that is may be related to the native Busybox on your rom. a2sd usedtbusybox will use the Busybox that is packaged with Darktremor. a2sd usedefaultbusybox will turn back on the scan behavior of the program introduced in Beta 03.

10. Support for Darktremor Apps2SD version 2.7 and earlier has been discontinued. To upgrade correctly from one of those versions, use version 2.7.5.3 Beta 03b or earlier.

11. Finally fixed stalled boot issues (or at least my tests with several roms says so.)

See the change log for additional details.

You will notice that if the program runs repair and finds a problem, it will correct the issue and reboot. You will see a second reboot when the dalvik-cache clears (this is to fix timing issues with CyanogenMod...I can't control that startup as well as I can other roms). This only happens if repair is ran or you flash a new rom (as repair will realign all data). If you are upgrading from a previous version of Darktremor, you should not see the reboots.

This is Darktremor Apps2SD, a multipurpose program that primarily allows a user to execute applications created for the Android OS on their Secure Digital card (with the proper setup...more on that later). But, Darktremor Apps2SD is all about stability. The goal is to be able for all users of the Android OS to be able to take advantage of a method to run their applications from a secure digital card.

But just because the Darktremor Apps2SD is all about stability, doesn't mean it isn't packed with features:

- Move applications (both free and paid) to the Secure Digital card.
- Move Dalvik Cache to run either from your Secure Digital card or from your cache partition and clears the cache on demand.
- Boot Loop Protection: prevents the phone from boot looping in the event the SD card could not be mounted.
- Dalvik JIT for faster performance on Roms which support it.
- User selectable sizes for the Dalvik heap sizes, allowing a user to freely optimize their system.
- Activate a swap partition on your SD card and sets how often the swap partition is utilized.
- Automatically fixes configuration issues.
- Users can check the free space on their SD card and check the installation to make sure all is setup correctly.
- Runs ZipAlign on demand...this makes your programs load faster.
- Built in help system for easy reference of commands.
- All features can also be reversed without repartitioning your Secure Digital card.
- New logging features assists in troubleshooting issues.
- Commands to set the Low Memory Killer feature at boot time. Great for those people who are the "set it and forget it" type.
- And more...

Darktremor Apps2SD is not the same as Froyo Apps2SD. Froyo Apps2SD creates a secure folder on the FAT32 section of your SD card (this is the section that you see when you mount your phone to your computer) and stores the programs there. This is nice as you don't have to do anything special with the phone, but it isn't backwards compatible with older versions of Android (Cupcake, Donut, Eclair) and, because of the way Froyo works, older programs not designed for Froyo will automatically stay on your internal storage (unless you install a program that forces the move to your SD card).

Darktremor Apps2SD takes a different approach. Based on the original CyanogenMod works, Darktremor Apps2SD uses symbolic linking to force Android into moving your applications to the SD card. Because Android will not allow anything to be ran from the FAT32 partition on your SD card (and, in Froyo, it will only allow you to run programs from a special folder), Darktremor utilizes filesystems called EXT2, EXT3 and EXT4. Each one of these filesystems is native to Linux (the operating system running Android), which allows you to run programs from them (same as, say, a computer running Ubuntu). This method is completely compatible with all versions of Android, including Froyo. In fact, you can run both the Darktremor Apps2SD and Froyo Apps2SD at the same time.

Is there really any need for this if we have froyo? If so please fill me in, I just don't see the point.

*cough* TROLL *cough*

But in case you were serious, there is a need for it.
A). Some phones are quite limited on the amount of space they have. Apps are getting bigger and bigger (3D games, Flash, video chat, etc). Phones are now coming with multiple gigs available for /data, so if you have a phone with only 256mb available, you'll feel the pinch very quickly.

B). Froyo's version of apps2sd relies on the developer to allow an app to be moved, and even then, the entire app DOESN'T move - only the parts that they allow to move. So even on the SD card, an app might still take up 10s of megs. Google Earth, for example, barely moves off the internal memory at all.

C). Froyo's version of apps2sd doesn't allow you to move home apps, livewallpaper, or ANYTHING that has a widget (which is a lot of apps). Rebooting will cause widgets to disappear.

Even if there are some advantages, has anyone actually filled their internal storage on the mt4g already? Hell, to be honest I don't even see the need for froyo's apps2sd. I've installed every app I could possibly find a use for (on internal storage) and still have over 500MB free.

To the people who don't think there is a need for this, quite simply, don't use it.

It's a tool. Not everyone has a need for all tools. Please just leave it at that.

I and many others, on the other hand, do. I have a Desire and pretty much the prime reason for me rooting was a lack of internal space. So thanks tkirton for trying. Even if I can't use it at the moment! lol

I did a clean install of CM 6.1.1, then Gapps, then Darktremor beta 03, .... and I don't think it worked. In addition, I'm not sure what I would have seen to know that it worked.

I also when into the Terminal Emulator and tried "app2sd cachesd" and I got a whole load of "permission denied" after every command line that popped up.

Is it just not working with Desire (I notice a Desire HD user with a problem) or am I just doing something dim? I'm prepared if it's the latter. I can take it!

Has anyone gotten this to work on the glacier? Clockwork won't mount the ext 4 and I can't get a2sd to install

It works for me. Mount system and data in recovery before you flash.

better put some water on that ****!
