it shouold be slowerd as odex filex are some kind of platform-specific bytecode

So i would benefit , keeping the original contents for most apks, and maybe just change Rosie.apk or whereever to fix the graphics in the alarm/timer thing, which actually is so small so slowing it down, would not be a wise approach, as it almost works fine.

[luismanson]

i think that odex files should be deleted as they do nothing on our milestone (im NOT sure)

according to smali project:

In short, an odex file is an optimized version of a classes.dex file that has optimizations that are device specific. In particular, an odex file has dependencies on every "BOOTCLASSPATH" file that is loaded when it is generated. The odex file is only valid when used with these exact BOOTCLASSPATH files. dalvik enforces this by storing a checksum of each file that the odex file is dependent on, and ensuring that the checksum for each file matches when the odex file is loaded.

The BOOTCLASSPATH is simply a list of the jars/apk from which classes can be loaded, in addition to the main apk/jar that is loaded. A normal android system has 5 jars in it's base BOOTCLASSPATH - core.jar, ext.jar, framework.jar, android.policy.jar and services.jar. These can all be found in /system/framework. However, some apks have dependencies on additional jar or apks files beyond that of the base 5 jars. For example, for applications that use google maps, com.google.android.maps.jar will be appended to the BOOTCLASSPATH for that application's apk.

These odex dependencies make life a bit difficult for a couple of reasons. For one - you can't take an apk+odex file from one system image and run it on another system image (unless the other system image uses the exact same framework files). Another problem is that if you make any changes to any of the BOOTCLASSPATH files, it will invalidate every odex that depends on that file - basically every apk/jar on the device.

"Normal" apps have an APK with a manifest, resources, and a
"classes.dex" inside. The classes.dex is optimized by the package
manager on first use, and ends up in /data/dalvik-cache/.

"System" apps have the DEX optimization performed ahead of time. The
resulting ".odex" file is stored next to the APK, the classes.dex is
removed from the APK, and the whole thing works without having to put
more stuff in your /data partition.

The optimized DEX files cannot easily be converted back to unoptimized
DEX, and I'm not sure there's any benefit in doing so. Both kinds of
DEX files can be examined with "dexdump".

More detail can be found in dalvik/docs/dexopt.html in the source
tree, or on the web at:

Dalvik Optimization and Verification

lets see what others have to say, this is way out of my league

Been using 0.3 for two days this are the bugs ive found:


*I get a LOT of loading screens saying htc and the homescreen reloads ALL THE WIDGETS , whats up with this? im guessing the 256 mb of ram in the milestone are not enough for sense

*The hardware keyboard DOES NOT light up =(

*The browser isnt "multitasking proof" when i switch to the homescreen and switch back to the broswer it reloads the homepage again im guessing this has to do with low ram again and android has to close the browser in order to free ram =(

* The tabs look f*cked up, distorted,i dont know how to describe it, but it has mentioned this is due the milestone having more resolution than the desire? can some of the users here fix this?

*A LOT of things dont work in landscape but this htc's fault , i kinda forgive them but does the music player really doesnt work in landscape? i get force closes =/

*Everytime i reboot the phone or sometimes even withouth a reboot the language and region is back to the original one =/

Also i get an error when i send sms with more than 160 caracters, aka 2 messages in one, the last bit of the seconds sms gets chopped , thats what my friends claim , and in the phone i get a message impossible the send the message and then automatically after 2-3 seconds it sends the message =/

deleted, figured it out, i think..

Have finally got the deodexing to work, but the order of loading the apk's causses some inconsistency checks to fail, just like if i did a "touch *" on all apk/odex in the original flash edition.
So now i have to figure out setting correct a/mtime on files, to make it load correctly..

it has gone from about 148MB to 89MB, and which could easy the changing of graphics... I do note that now the starting is kinda slower, and processing is not as good as with odex files?
Skrilax_CZ: Do you know/can confirm using deodex'd files is slower for the AndroidOS?

Yeah it is as I supposed but it should be slower only on the loading. Well point is that it will give you much more flexibility now, like modifying the framework.jar (adding FLAC support, etc.) - also we can have a look on the dependencies in the greater detail - can you release the deodexed version so I could "implant" it to my system partition and have a look?

[DAGr8]

wow this is getting more and more polished keep it up guys !

i will not release a image with these files, it is simply too slow.. but here are the files..
I have sorted the "apk's" so those are tar'd, and needs to be extracted directly to /data/.app , so the order is maintained or it will load incorrectly. (still not sure about why, but seems there are dependencies)

here is the file.

i have a maybe a stupid question....

can we install custom roms for HTC Desrie from RomManager??

THX

THX

no, there is too many differences in the image.
HTC Desire is in no way hardware compatible, so everything related to this needs to be modified to work.

But i have thought about trying one of them, problem is now, that the custom roms with deodex'd api and apps, seems very slow, and that is for not a goal to make it slower now.
But yes, without it, we cannot fix any graphics problems.

[landroid]

so we can.....but it'll be slow as hell


and also....'r' you working on other image....no pressure.....just to know

[dext3r]

i hsve been looking at the SDcard and BT problems, but thats it, and no good news yet..

but when something new works, or even Froyo gets to htc and our milestone too, i hope that somehow i can replicate the image and maybe better luck on sdcard and BT problems.
but while i wait, i will look at the current problem.
Graphics will probably not be fixed.

what about the "htc screen" and loading that shows up constantly? can it be fixed? or is it because of the "small ram" -256 mb-?

somehow related to memory, as debugging and looking at logs, it clearly shows its low on memory, but maybe it can be tuned somehow to utilize it better.. but thats another work in progress, but yes, i use it daily myself, and when too much has been started it gets annoying, and would be great to get around.

when u fill the screen with widgets , its inevitable =( sooo annoying =(

[Rhole]

Is there a way to get the Overclock module to load at boot every time?

I tried Autostart and no luck, and the mot_boot_mode gets rewritten.

Excellent port, been using it daily for the past 2 weeks.
