How to compile MapBox SDK

I am a Android Developer.
Recently, I was working on the compilation of MapBox SDK.
I want to follow the official website steps，But I developed it on Windows，
I want to change the source code，instead of just using aar.
enter image description here
So,Can someone tell me what to do?thank you.
Yesterday I tried to import the mapbox project,download CMake,cUrl..,I find the build.gradle of module，There is a note：
// Load build system information. If this file does not exist, run
// `make platform/android/configuration.gradle`
apply from: rootProject.file('configuration.gradle')
make,it's linux command，I use the windows system,so I download the MinGW.
but when I use this command to build configuration.gradle, i got failed:
make:***FATAL***platform/android/configuration.gradle:unknown action keyword
so i tried to use this code in android studio Terminal,but it can't use make、cmake or other,so how can i build this file.
I've been getting this mistake：
Error:(22, 0) Could not read script 'F:\AndroidStudio\AndroidStudio_WorkSpace\mapbox-gl-native-master\platform\android\configuration.gradle' as it does not exist.
or someone has ever done this,could you give me your configuration.gradle,so i can modify it.
thank you.

You should be able to compile the SDK in Windows. The easiest way is to use CMake from within Android Studio. Note however that CMake support is only for the 64 bit version (I believe) not for the 32 bit version of Studio.
If you're building from the command line, then 32 bit or 64 bit both work because NDK is available for either. To do that, you'd write something like:
./gradlew.bat -Pmapbox.buildtype=debug -Pmapbox.abis=all :MapboxGLAndroidSDKTestApp:assembleDebug

getting error during project creation using phonegap-2.5.0

i have installed android sdk and downloaded the latest version of phonegap 2.5.0 in fedora 18.
i am trying to create a project using the following command
./create ~/Desktop/android-project com.example.android android_project
am getting the following error.
which: no android in (/sbin:/bin:/usr/sbin:/usr/bin)
An unexpected error occurred: ANDROID_BIN="${ANDROID_BIN:=$( which android )}" exited with 1
need your valuable suggestions.
finally found the answer
After checking my .bash_profile paths, and a bunch of digging, I finally found the cause of the issue. If you open up the create file (phonegap-2.5.0/lib/android/bin/create), there is a line that lists ANDROID_BIN=”${ANDROID_BIN:=$( which android )}”. The “which android” is the cause of the issue (or at least it seemed to be in my case). If you replace this line with the full path to your android tools (as listed below) it should resolve the issue. My final line looked like this:
ANDROID_BIN=/Users/ktyacke/DEV/adt-bundle-mac-x86_64-20130219/sdk/tools/android

The message you have means the phonegap script cannot find the android binary, which is included in the SDK you downloaded. Add the binary's directory, as well as the android tool's directory, to your path defined in ~/.bash_profile or any other location you're initializing the shell's environment variables.

Deploying SDK Addon component

Based on PlatformLibrary sample code in the SDK, I have created a small hello world library, the eventual goal of the library is to add capability for 3rd part developers to develop for my custom Android image.
I am currently stuck at the point on how to deploy the same so that developers can start using it, I am unable to find any pointers, please help if you have any information.

Ok, I figured out based on for 4.0.3
Create a new sample device, based on the the existing one located at
<SDK-ROOT>/device/sample
build the sdk-addon
<SDK-ROOT>$ . build/envsetup.sh
<SDK-ROOT>$ make -j8 PRODUCT-<your-sdk-addon-name>-sdk_addon
Once the SDK is build you will get the sdk addon archive located at
<SDK-ROOT>/out/host/linux-x86/sdk-addon/<sdkname>.zip
I copied the ZIP to the http server directory, so that it has a link I can refer in Android SDK manager.
Created new SDK XML configuration file and put it in the http server (I used the one located at http://android-sdk-addons.motodevupdate.com/addons.xml for reference)
Went to Android SDK manager, added path to new add on XML created on #5 and OK
Install the new SDK On listed in the android SDK manager, after the installation is done, you can get check the add-ons directory of ur developer SDK to find the add-on.
Also bits and pieces from marakana.com/s/remixing_android,1044/index.html helped.

Looks like you resolved your own issue, but just FYI - to simplify/automate your step #5 above, you can use the mk_sdk_repo_xml.sh script provided under platform/development/build/tools to build the add-on repository.
This is actually used by the phony 'sdk_repo' target (platform/development/build/tools/sdk_repo.mk), so you can take a look to see what the intended usage is. It has the benefit of managing all the packaging/checksum generation etc for you.
Note that it's supposed to provide some automagic behaviour based on the ADDON_SDK_ZIP which is defined by the sdk_addon build task, but that never worked on our customized gingerbread platform, so I ended up putting in an explicit call like this:
$(shell $(TOPDIR)development/build/tools/mk_sdk_repo_xml.sh \
$(TOPDIR)out/host/linux-x86/sdk_addon/addon.xml \
$(TOPDIR)sdk/sdkmanager/libs/sdklib/src/com/android/sdklib/repository/sdk-addon-1.xsd \
add-on any $(TOPDIR)out/host/linux-x86/sdk_addon/LIBRARY_NAME-eng-linux-x86.zip:sdk-repo-any-addon-LIBRARY_NAME.zip )

I figured out based on 4.4.2 and Andrdoid Studio 1.4, and it doesn't need put sdk add on xml to web server.
1.Create a new sample device, based on the the existing one located at
<ANDROID-ROOT>/device/<your-sdk-addon-name>
2.build the sdk-addon
<ANDROID-ROOT>$ . build/envsetup.sh
<ANDROID-ROOT>$ make -j8 PRODUCT-<your-sdk-addon-name>-sdk_addon
3.Once the SDK is build you will get the sdk addon archive located at
<ANDROID-ROOT>/out/host/linux-x86/sdk-addon/<sdkname>.zip
4.Extract .zip to
<SDK-ROOT>\add-ons\<your-sdk-addon-name>
5.Copy
<ANDROID-ROOT>\device\<your-sdk-addon-name>\sdk_addon\manifest.ini
to
<SDK-ROOT>\add-ons\<your-sdk-addon-name>
Create new file source.properties to <SDK-ROOT>\add-ons\<your-sdk-addon-name>
Addon.NameId=your-sdk-addon-name
Pkg.Desc=Provides the oem APIs to 3rd party apk developer
Addon.VendorId=your-sdk-addon-vendor-name
Archive.Arch=ANY
Addon.NameDisplay=your-sdk-addon-name
Addon.VendorDisplay=your-sdk-addon-vendor-name
Archive.Os=ANY
Pkg.Revision=1
AndroidVersion.ApiLevel=19
Open SDK Manager, your will see your SDK add on listed
New a Android Studio project, edit build.gradle file:
android {
compileSdkVersion "<your-sdk-addon-vendor-name>:<your-sdk-addon-name>:<sdk-api-level>"
...
}
Build the project, your add on jar will be loaded to External Libraries in Android Studio

Proguard ParseException with Default proguard.cfg on Android

I am about to release an application but, while i was building it using Export Tool of Android SDK in Eclipse, i get the error below.
I didn't change the proguard.cfg.
It is in the root folder of my project.
I only add proguard.config=proguard.cfg to default.properties.
I read the forum and update proguard (just copied the files to the tools folder of Android SDK), but still I doesn't work. I couldn't figure out what the problem is with the 'Projects\Eclipse' ??
If you help me, I will be so glad...
[2011-08-08 02:32:46 - CoolProject] Proguard returned with error code 1. See console
[2011-08-08 02:32:46 - CoolProject] proguard.ParseException: Unknown option 'Projects\Eclipse' in argument number 9
[2011-08-08 02:32:46 - CoolProject] at proguard.ConfigurationParser.parse(ConfigurationParser.java:172)
[2011-08-08 02:32:46 - CoolProject] at proguard.ProGuard.main(ProGuard.java:484)

Yeah that is right, but also I did something that I didn't know :)
My solution was:
I updated to latest Android SDK.
I changed SDK path property under Eclipse: Window > Preferences > Android > SDK Location as something like c:\Progra~1\android-sdk. The Progra~1 can be used for writing Program Files witout spaces. You can use DIR /X command in command prompt on Windows to get no space versions of Paths.
I moved my Eclipse Workspace to a location without spaces like D:\
The changes above didn't enough to solve the problem. I got "Conversion to Dalvik format failed with error 1" error dialog witout any explanation on output console. Then I found that topic and did what that reply says.
Then it worked ;)
I am using Windows 7 Ultimate x86. I hope it works for others too.
Arda.

Your project path probably contains a space. This should be fixed in the latest version of the Android SDK (at least for the Ant build). Otherwise, you should use a path without spaces for the time being.

How to build Android NDK sample: "bitmap-plasma"

I am trying to build the bitmap-plasma sample that is included with the ndk, but getting an error. I run ndk-build from the samples/bitmap-plasma directory, and the error it displays is that it cannnot locate android/bitmap.h file.
How do i direct the ndk-build script to the file it needs?
Using android-ndk-r4 on Ubuntu Lucid 10.04

Well it's working now, so in case anyone was having my same problem:
There as an android-ndk-r4b bugfix release today, which it seems no longer has this problem.
Available to download here.
http://developer.android.com/sdk/ndk/index.html

With Ubuntu 10.04 and NDK r5b, I have just posted a bug report (with the fix included) for build_platforms.sh. See http://code.google.com/p/android/issues/detail?id=15180 for details. Essentially, the local declarations in the symlink routine must be amended. Otherwise, it only links the first file (alphabetically) from each directory, and truncates the remainder from the list.
Correcting this allowed the symbolic links to be fully populated, thereby filling in the missing header files and libraries and allowing the samples to build successfully.
