Fuse: Android NDK R7 is integrated with Cywin and does not bother to download and configure Cywin when developing the NDK.Android NDK Development Steps:
Eclipse first configures the NDK path, WINDOWS–>PREFERENCES–>ANDROID–>NDK, to specify the
1. Resources(1), Android's Eclipse development environmentI use adt-bundle-windows-x86. The official homepage will be available for download. This is a packaged version number that executes directly eclipse.exe you can start(2), NDKDownload ndk (download them online)(3), Cygwin64For simulating the Linux execution environment (
1. Preparatory workBefore we actually write the code, we need to do some preparatory work first:
Download NDK Development Kit:Android official download page
Configuring System Environment Variables
After downloading the NDK development package, unzip directly to any directory, then need to configure
GNU make 3.81 or later!2. Define the GNUMAKE environment variable to point-to-it, as in: export gnumake=/usr/bin/make3. Call ' Ndk-build ' again.began to look for a half-day did not find a solution, and then carefully see found currently using:c:/mingw/bin/make. This make is not cygin/bin below make, and then I remember to configure the Eclipse C + + environment to use MinGW to temporarily remove the value from path to solve the problem.3. Compil
Zero Android basic configuration win7_32 + opencv2.4.6 + eclipse + ndk, win7_32ndk
The Android + C mode should be the most ideal method for porting opencv code.Less oldJdk, sdk, ndk, and eclipse are updated in just a few versions. There are a lot of different things. No way, you have to configure the environment if you want to transplant it. to accompany the new version of the environment, you have to pay
1. Cryptographic Library Cryptopp Compilation However, error Fd_set not knowSolution: http://morgwai.pl/ndkTutorial/The last problem was that crypto++ seems to rely on implicit inclusion of header file containing definition of fd_set . This isn't the case if using STLport so need to add the following preprocessor command somewhere in wait.h file:#include 2.cccommon.cpp File Error:/cocos2dx/platform/android/cccommon.cpp:54:77:error:format not a string literal and no format arguments [-werror=form
I. Windows:The following software must be installed in a Windows development environment:
Java JDK
Apache ANT Build System
Android SDK
Cygwin
Android NDK
Eclipse IDE
1. install Java JDK
Http://www.oracle.com/technetwork/java/javase/downloads/index.html
Configure environment variables:
Create a JAVA_HOME key with the value set to the JDK installation directory.
Open the PATH key and add
; % JAVA_HOME % \ bin
Detection:
Javac-version
2. install Apache A
Some ARM toolchains can be found online, but the Android system uses Bionic libc instead of glibc. Therefore, only static compilation programs can be used.
In fact, Android NDK comes with toolchain, but you cannot directly use the toolchain in the ndk directory. Otherwise, the crtbegin_dynamic.o file cannot be found.
That is, you can use-L to specify the directory or directly put it in the gcc command lin

The game project began to turn to Cocos2d-x for development. What ndk and cygwin do you need. Start learning with a hard head.
1. Download ndk, the latest version of R7. Decompress to D: \ develop, address: http://dl.google.com/android/ndk/android-ndk-r7-windows.zip

Use NDK to implement cross-compiling between C and Java in Android.
Java in android relies on Java virtual machines, and its running efficiency is relatively low. Recently, in the efficient multiplication of large numbers, we found that JNI or NDK can implement mixed compilation of C and java, in addition, the dynamic library of c is referenced, and the c language in android does not need to rely on the Jav

Download android-ndk32-r10-linux-x86.tar.bz2 from https://developer.android.com/tools/sdk/ndk/index.html ;3, copy the android-ndk32-r10-linux-x86.tar.bz2 to Ubuntu/home/spring/neon folder, and unzip;4, configure the environment variables: in the terminal input sudovi/etc/profile, open the profile file, at the end of this
Use of NDK in Android Studio
When developing android programs, we sometimes need applications to call underlying hardware. Android officially provides us with NDK so that we can call the C, C ++ library in our program. Ndk is a set of tools developed based on java jni technology for android programming. It can help us quickly develop dynamic libraries of C or C +
Because Android apps are decompiled to see the information in it, and some sensitive information, such as the server IP address and encryption algorithm, we do not want to let others know. How can we hide this information? As far as I know, we can use Android NDK to compile the data in the so file and obtain it through JNI to protect sensitive information, that is, NDK hides sensitive information.As a resul
Recent research on the incremental upgrade features of Android apps, which involved the NDK development content, was documented here. Say a few questions first. First, the NDK development is JNI development Ah, I did not know the trough, I always thought it was two things ah ... Second, about the development environment, the old version of Eclipse to install more tools, what

Android Studio uses the new Gradle build tool to configure the NDK environment and gradlendk
Android Studio 1.3 Beta1 supports NDK. However, it uses a brand new and experimental gradle build tool. Official Address: http://tools.android.com/tech-docs/new-build-system/gradle-experimental.
Before configuration, update Android Studio to the latest version. The latest version is 1.4 Bata4.

The NDK programming for Android requires the download of the NDK compilation environment, which can be downloaded from the official website window64 and then extracted to any directory.The implementation of the NDK is actually using the Jni method in Java, so the previous steps can refer to the implementation of JNI, b
