Write applications in C or C++ for Android? [closed]

Answer 1

This three steps are good to have and store in this post.

1) How to port native c code on android

2) http://www.integratingstuff.com/2010/12/12/calling-native-c-code-through-jni-in-android-applications/

The official position seems to be that this isn't something you'd ever "want to do". See this thread on the Android Developers list. Google envisage android running on a variety of different devices (CPUs, displays, etc). The best way to enable development is therefore to use (portable) managed code that targets the Dalvik VM. For this reason, the Android SDK doesn't support C/C++.

BUT, take a look at this page:

Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework.

The managed application framework appears to be layered on-top of these libraries. The page goes on to list the C/C++ libs: standard C library, media, 3D, SQL lite, and others.

So all you need is a compiler chain that will compile C/C++ to the appropriate CPU (ARM, in the case of the G1). Some brief instructions on how to do this are here.

What I don't know is where to find descriptions of the APIs that these libraries provide. I'd guess there may be header files buried in the SDK somewhere, but documentation may be sketchy/missing. But I think it can be done!

Hope thats useful. For the record, I haven't written any native android apps - just a few simple managed ones.

This blog post may be a good start: http://benno.id.au/blog/2007/11/13/android-native-apps Unfortunately, lots of the important stuff is "left as an exercise to the reader".

Answer 4

Google has already launched Google I/O 2011: Bringing C and C++ Games to Android session which is available at http://www.youtube.com/watch?v=5yorhsSPFG4

which is good to understand the use of NDK for writing application in c and c++ for android.

If you just want to cross compile any console based native game and run them on android then this Article has shown 3 methods for the same.

1: Static compilation using standalone toolchain

2: Cross compilation using Android NDK’s toolchain

3: Cross compilation using AOSP source code

Answer 5

Since 2009 there is a development on this matter.

Native C/c++ Files libstdc++.* from your Ubuntu are x86 (or x86_64) binaries but Android devices and emulators are ARM. Of course, this will not work anyway, even if you'll set correct soname. This is very naive way which leads nowhere. Android has very limited support of C++ meaning there is no exceptions, standard C++ library (including STL) and RTTI. If you need such functionality, use my custom NDK distribution from

http://crystax.net/android/ndk.php - it support full C++ features listed above.

Why is there error: undefined reference to '__cxa_end_cleanup' link error. Android stlport

time. Because there is no link to libstdc + +. A. So wrong.

Because it uses some static library, it is necessary to link the full libstdc + +. A. Can

http://crystax.net/android/ndk.php here to download the package

sources \ cxx-stl \ gnu-libstdc + + \ libs \ armeabi directory.

Android on its own libstdc + + support is limited, it must be linked to a complete libstdc + +. A the job.

Add file in Android.mk LOCAL_LDFLAGS = $ (LOCAL_PATH) / libs / libcurl.a \

 $ (LOCAL_PATH) / libs / liblua.a \
 `$ (LOCAL_PATH) / libs / libstdc + +. A`  

And LOCAL_CPPFLAGS + =-lstdc + +-fexceptions can be compiled
