Example 2 Triangle NDK OpenGL ES API with no current context #20

Open stericardo opened 9 years ago

stericardo commented 9 years ago

I buy the book. The example 2 of the triangle, I do steps of chapter 16 for build with Android NDK.

I have android 4.4.2. NDK: android-ndk-r10e

ENVIRONMENT VARIABLES WITH CYGWIN:

export JAVA_HOME="/cygdrive/c/Program Files/Java/jdk1.7.0_45" export ANDROID_SDK=/cygdrive/c/Users/steven.mendez/sdk export ANDROID_NDK=/cygdrive/c/Users/steven.mendez/Documents/Development/Android/android-ndk-r10e export ANT=/cygdrive/c/Users/steven.mendez/Documents/Development/apache-ant-1.9.2\bin export PATH=$PATH:${ANDROID_NDK} export PATH=$PATH:${ANT} export PATH=$PATH:${ANDROID_SDK}/tools export PATH=$PATH:${ANDROID_SDK}/platform-tools.

After install(adb install -r bin/NativeActivity-debug.apk), I do test on my mobile, but the error on adb is:

Why is present this error ?.

it should work fine ?

\ 1 ****

Hi, I do steps ¨BUILD FOR UBUNTU LINUX¨ chapter 16, but on Windows 7 with cywing, all is working fine.

I think so my problem is that my phone, it have android 4.4.2 but look that not support OpenGL ES 3.0, only OpenGl ES 2.0.

I'm not sure if the error with NDK build is for this reason.

***** QUESTION ***

Only I have one last question, why do work fine on my windows 7 ?

If Windows 7 support until OpenGL 4.0. ( I known that my windows 7 support OpenGL 4.0, thanks to OpenGL Extensions Viewer 4.1.2, my renderer is Intel(R) hd Graphics 4000)

I understant that OpenGL ES 3.0 is based on OpenGL 4.3.

Is Cygwin the emulator that achieved this ?
