Android Kernel Development Environment Setup?

Dec 6, 2012

i am trying to look into android goldfish code and probably make some changes in it. As it is a long way to go for me i am actually unable to decide the tools that i need to set up. I come from an IDE based programming experience so am always trying to find a walk through tutorial to get goldfish kernel code in eclipse CDT to browse and code but no luck.I have followed the post source.android.com/source/building-kernels.html and built the kernel accordingly.wiki.eclipse.org/HowTo_use_the_CDT_to_navigate_Linux_kernel_source but am still not confident of my setup.

Android kernel development environment setup?


Android :: Development Mode And Maintaining Environment Variables

Nov 16, 2009

I'm building an Android application and would like to maintain a few environment variables that I can tweak depending on whether I'm in development mode or release mode. For example, I need to invoke a web service and the URL will be slightly different in either mode. I'd like to externalize this and other settings so I can change them easily based on my target deployment. Distinguishing development mode and release mode environment settings on Android. Are there any best practices or anything in the SDK to assist with this need?

I've been trying to setup a perfect development and testing environment for:

1. 1st attemp
I installed Android (android-x86-4.0-RC2-eeepc.iso) on Virtualbox but run into these problems:

* "adb remount" not working, even with "su"
* I had to run this every time I start the device (8.8.8.8 is Google DNS)

# dhcpcd; setprope net.dns1 8.8.8.8
* Google apps not responding

2. 2nd Attemp
I used Buidroid (buildroid_vbox86p_4.0.3_r1-20120518.ova) and run into these problems:
* ALT F1 does nothing, I know I can use a terminal emulator but I like ALT F1
* I had to run this every time I start the device (8.8.8.8 is Google DNS)

Code:
# dhcpcd; setprope net.dns1 8.8.8.8

Android :: Vim Setup For Development?

Jul 2, 2010

Can anyone describe a good vim setup for Android Development? I'm using Eclipse for now but I would really like to use vim because it's faster and I like it better. I'm not interested in Eclim for example.

I'm interested in what vim plugins are used (for java, autocomplete etc.), how the vimrc looks like and how the whole process of building/running applications works (as efficient as possible).

Samsung Moment :: Joeys Kernel And Get Stock Kernel Back

Jun 11, 2010

where 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?

Android :: Environment To Run Inside Windows?

Oct 14, 2010

I was just wondering if there was an Android environment that would let you run Android OS inside/alongside Windows, like Virtual PC basically, and let you have full connectivity just like if you were using your phone. I'm not sure what the utility could be right now but it sounds interesting to me.

Android :: Seemingly Useless Debugging Environment

Feb 17, 2010

I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
int a = 1 / 0;
}

Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

Android :: Scripting Environment For Application - No Way Of Accomplishing

Oct 13, 2009

I'm trying to make my app scriptable. Specifically, I need to expose a few Java APIs and make callbacks settable via user-written scripts. Ideally I'd like to hide some of the complexity away in a DSL, but there's no way of accomplishing what I want neatly without some form of user scripting, so I may accept another alternative if it meets my requirements. Initially I looked into Scala as that is my main language of choice, but the Scala interpreter is just a wrapper around its compiler, which I'm told won't run well if at all on the phone.

I've also tried JRuby, which worked under Cupcake. There appears to be a regression in the form of a Dalvik bug that prevents it from working under Donut, however:
http://code.google.com/p/android/issues/detail?id=4242
I've also seen the Android Scripting Environment. Am I correct in assuming that this only supports running full interpreters and not embedding scripting languages into apps?

Android :: Calibration With The Environment May Improve The Readings?

Jun 9, 2009

Reading the sensor API (http://developer.android.com/reference/android/ hardware/SensorManager.html) The section about ACCURACY speak about calibration:

"calibration with the environment is needed"

How do it calibrate?! Is this software calibration? Phone specific calibration??

I don't see any methods to calibrate.

Using the HTC Magic the compass often give me crazy values like if I was on the magnetic pole. I feel pretty scared and hide under a tinfoil hat just in case...

So any url, doc or explanation!

Android :: Get User Defined Environment Variables?

Sep 20, 2010

I would like to use self defined Environment variables in my source code.

I use System.getenv() to do this and the code line looks like this. Log.d("MyTest","== MyEnv " + System.getenv("AP") + " ANDROID_ASSETS:" + System.getenv("ANDROID_ASSETS"));

Before I execute my code I define my AP variable with export: export AP="12345" and the this is my output of set command

ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=9,32768
ANDROID_ROOT=/system
AP=12345

Then I execute my code and I get this line from logcat

D/MyTest( 5363): == MyEnv null ANDROID_ASSETS:/system/app

The value for my defined Environment variable is null. Any suggestions on why it didn't work?

Android :: Removing Public Static Fields In OS Environment?

Sep 20, 2010

Looking at the example code in the docs
http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir%28java.lang.String%29
File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.
