问题 After reading over the NDK docs and all my books on OpenGLES ive hit a wall. I am trying to copy my iOS OpenGLES set up to Android NDK R7 and above, mainly to get the depth buffer i overlooked earlier on when coding. The problem is i loose the textures on some objects when i enable the color buffer as seen below and the depth buffer isn't working when i send objects into the background. I am using OGLES 1.1 FFP and NDK R7 or above Here is my initialization code :- int32_t ES1Renderer:

I would appreciate if anyone could show me where I can get good tutorials or documentations for developing OpenCV 2.4.3 for Android. I already gone through the one on the OpenCv site and its more of configuration and getting started but not the real code explained. I want the opencv for android codes, functions

I am having issues in ndk-r7b and in ndk-r8 accessing the local read write directories using android_app->activity->internalDataPath or externalDataPath as they are both NULL. I see that this has been posted in previous versions and an update was going to fix this according to this post:- How do I write to the internal storage file system with NativeActivity? Now perhaps this gets fixed in Ice Cream Sandwich but that

I have the following situation, I am porting a piece of an app using OpenSSL for AES encryption, I have everything compile, but the linker fails. The situation is the following: 1. I wrote a JNI wrapper that simply does : private native String cipherString(String plainData, int datasize, String password, int passSize); private native String decipherString(String cipheredData, int datasize, String password, int passSize); next I have a c++ file which I call that has the proper JNI sintax which translates jstring to char * and all other needed transformations, and makes a call to another cpp

I'm trying to add native code to my app. I have everything in ../main/jni as it was in my Eclipse project. I have added ndk.dir=... to my local.properties . I haven't done anything else yet (I'm not sure what else is actually required, so if I've missed something let me know). When I try and build I get this error: Execution failed for task ':app:compileDebugNdk'. > com.android.ide.common.internal.LoggedErrorException: Failed to run command: /Users/me/android-ndk-r8e/ndk-build NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/Users/me/Project/app/build/ndk/debug/Android.mk APP_PLATFORM=android-19 NDK
