Hi,
I had the need to update one of my customer app today.
It was using gradle 0.6 with a snipped of code to compile it I wrote myself
modifying what I found suggested in this very forum.
The new Android Studio forced me to switch to gradle 1.9, which in turn
force me to switch to android gradle plugin 0.7.
This include the NDK support.
I'm using NDK version: ndk-r8e
I switched everything to the new version, commented out my custom code for
building the NDK then tried:
$ ./gradlew clean assemble

Googling I found out I should add the ndk.dir to local.properties, even if
I had the environment variable ANDROID_NDK_HOME correctly set up.
did so then re-issued the command:
$ ./gradlew clean assemble

I'm not very expert with C / C++ issues...
but I found two things to be very weird:
NDK_PROJECT_PATH=null
APP_PLATFORM=18
APP_ABI=all
I specified in Application.mk:
APP_ABI := armeabi armeabi-v7a
APP_PLATFORM := android-9
It seems to completely ignore my Application.mk
This was my perfectly working (on gradle
1.8, com.android.tools.build:gradle:0.6.+ plugin) build.gradle file (the
part I added for compiling NDK):

Can you help me out?
Thanks and regards,
