I haven't messed around with android kernels yet, but I have applied it to my current Ubuntu 10.10 system and you can see the difference. Its like night & day!
Is Android is going down a dead end?
When will Google rejoin the Linux kernel community?
Is it Goodle's business model (spyware by any other name?) clashes with the ethics of the open source community?
i want to add some features to linux kernel to run on my mobile (android based mobile perhaps). but i don't know who let me to upload my custom kernel. i want to buy such mobile phone. some restrictions about uploading custom kernel to phone:
1- replace existing kernel.
2- can use my phones functionalities: it is due to some drivers are closed source and i must use the vendor's kernel to use it's drivers.
How to build latest linux kernel from off site for Android device (for example Nexus7)?
I have: AOSP source code
Android build for device (from aosp)
Downloaded kernel 3.8.4 from off site
The question is: How can I build latest kernel using all described stuff (aosp source, kernel config, latest kernel)?
I want to deliver some event to android application. I thought it should pass the event to android framework library and then transfer the event to android application. Is there any clear sample about such scenario? or anyone can show me the hint how to make it work.
View 2 Replies View RelatedI am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.
As I know that the Android boot sequence stages are as follow:
1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.
So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.
Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?
i successfully got into adb in recovery mode fairly easily on my ubuntu 10.4 laptop using the following method- this should also work for a linux live boot from a usb flash drive
in one terminal tail and follow log messages
~$ tail -f /var/log/messages
In another terminal run the loop
Then
1. plugin usb and keep it plugged in
2. remove battery, eject sd card.
3. put battery in
4. press vol- and power
5. after around 6 seconds, your terminal with the log will show something like "new high speed USB..."
6. press vol- to select recovery
7. press the power button
8. IMPORTANT- as soon as you see a new log entry (something like "USB disconnect"), pop in the sd card
check your loop terminal for adb. if it doesn't work, repeat at step 2
I have vanilla linux kernel version 2.6.27. I want to apply android specific patches and convert it to android linux kernel 2.6.27. Where can a user find the patches to convert a normal vanilla kernel into android kernel?
View 1 Replies View Relatedwhere I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
I know android is based on linux, does this mean it can run any and all linux applications? If so has anyone tried to run anything like wine? I also noticed that by default you cant run apps directly from sd card, but i saw a modification on a site that lets you change it so you can, so technically speaking is there any limit on the size of sd the G1 can handle?

View 1 Replies View RelatedI try to implement a hover effect (effect when button is pressed) through putting a semi transparent PNG file on top of the button background and the button icon. Unfortunatly the button background file is a 9-PATCH-PNG which causes some trouble here: It "swallows" everything on top of its layer and doesn't allow to cover the stretchable areas (the fine light line around) of the nine-patch-png. In other words, the black lines the top and left edge of the 9 PATCH PNG cause not only stretching, but also padding behavior.
View 4 Replies View RelatedAndroid has a nice way of defining stretchable images called a nine-patch. See these docs for a description of the concept. The idea is to surround a png image with a 1-pixel border where you can define the stretchable areas and the padding dimensions of the image. This is absolutely brilliant and I'd like to use the idea in my iPhone app. Before writing my own nine-patch to UIImage loader I thought I'd see if one already exists. Google doesn't return any results so I don't have much hope, but it doesn't hurt to ask, right?

View 8 Replies View RelatedI wish to customize the button images, but after I opened the png file, changed the color, reimported back into the draw9patch editor, the compiler spew out errors. how can I modify the 9 patch image of the default button?
View 2 Replies View RelatedI'm trying to create on of these images, but Eclipse won't accept it once I've used the draw9patch tool. I've found other people having the same problem, and saw this comment: I discovered later that the problem I was having was caused by the image not being exactly true to the nine-patch spec as defined in the documentation. Once I fixed the image to have a clean (i.e., no gradients etc) one pixel border it was fine. "'m not much good when it comes to image design. What does this mean, how do I create my original png file to meet the specification for Nine Patch?
View 2 Replies View RelatedI have some 9-patch images on my app, and they work great on the medium density. When I load the app on a High density emulator/device, these images look grainy. It happens only to 9-patch images. The others look great after the pre- scaling. Is there a way to make them look good after the scaling, like the non-9-patch images?
View 10 Replies View RelatedCan someone please explain or provide examples (links) of some valid 9- patch files? From reading the API description, I think my understanding is flawed. As an example, there's a 9-patch located at: http://www.maladroid.net/test.9.png Code...
View 9 Replies View RelatedI'm trying to draw a nine patch onto a Canvas object on the Android. What seems strange is that although I generated my nine patch using the draw9patch tool, the constructor for NinePatch requires an additional byte array called the "chunk" to construct the nine patch. Why isn't this simpler? What is the "chunk"? And if you have done this yourself, how did you go about it?

View 2 Replies View RelatedI'm wondering if there is something like 9-patch in Android, but for web development? Disclosure: I have no idea about web development at all, but I was curious to know if it exists. And a simple web search with the term 9-patch didn't bring up any related results, so I figured it has either another term or it doesn't exist or is not used widely enough.
View 1 Replies View RelatedI have a question regarding 9 patch images. Is it possible to download 9 patch png files from a webserver then display it as a background of a layout while keeping the information inside the file like the stretchable pixel? I have tried using a 9 patch image coming from the resource drawable directory of my project and it displays correctly...stretching only those pixels marked as stretchable but when I tried to download a 9 patch image from my web server then the application will use the downloaded 9 patch image the stretchable pixels does not take effect..i mean instead of stretching only those pixels that where marked as stretchable it stretched the whole image.
View 4 Replies View RelatedI want to set a specific background image for all my buttons. So, I changed my PNG file into a Ninepatch drawable using the "draw9patch" tool(by specifying the line of strecth).Then, I applied this as background to my button using
"myBtn.setBackgroundResource(R.drawable.new_png);"
Now, the background appears for the button, but the lines of stretch are also visible on the android screen, wherever I'd specified them in the tool. Can you help? Is there something wrong in how I'm using the tool?
I have an image with a fixed size , ex. 300 x 300 ; it was a background image of my view. But my view size was dynamic , so i need an image which can stretch , according to desired size. can any one tell me how to make it ? I know we have to use nine oatch drawable ? i don't know how to tool given with android sdk ? can any one tell me how to make image to png?

View 1 Replies View RelatedI am trying to use a nine patch image as a background in an android game. The image expands well in multiple resolutions but, my game has slowed down by 10 fps. I used to get a consistent 45 to 50 fps now I get 35 fps. The question is when we use a nine patch as a drawable and set it as a background in a view does it have any performance implications as opposed to a plain bitmap drawing.

The only way to connect to the Internet is through a VPN connection (PPTP), but it bothers me a bug in Android.The error I'm getting in the log is as follows:

I found a patch for it, and the manufacturer provides kernel available for download.Patch is here: code.google.com/p/android-x86/issues/detail?id=451...I tried to manually apply patch. I replaced some code in files if_pppolac.hi if_pppopns.h. But I do not know how compile kernel
I also tried to install latest fw update, several alternative ROMs and several VPN clients but nothing worked. always the same error: Socket () Protocol not supported. The best would be if I could put Jelly bean on box. In Jelly Bean pptp works fine.
Trying to figure out which kernel source Samsung took to maybe extract a patch set and create a newer kernel. Has anybody figured out where they exactly took the kernel from? I found that they have which are not found in the android/msm.git, but in the MSM/QSD git repo here: Has anyone tried to figure out the exact version/commit that they took?
