Android Studio (editor) cannot see Gst header files

[jeremi.wojcicki]

High Guys,

I'm beginning my adventure with Gstreamer framework for Android. I decided to use Android Studio rather that eclipse as it seems that it is probably a better choice for the future (AS is now the official IDE). Anywa,y I successfully managed to import, configure and build GST tutorials for android but one thing that still baffles me is that AS editor does not see GST header files:

I do not know how to solve it - i tried adding the path to the header in gradle.bulild file, but that does not bring any effect:

        ndk {
            moduleName "tutorial-4"
            abiFilters 'arm64-v8a'
            cFlags += "-I${file("F:/GST-android/arm64/include/gstreamer-1.0/")}".toString()
        }

Compilation runs fine, so GSTREAMER_ROOT_ANDROID is set correctly, it just that Android Studio editor complains that it cannot resolve any gstreamer structs or functions.

any ideas how to point AS to these headers?

In the end I solved the problem myself. So if sb would have similar issue in the future I post my solution.

It was needed to modify the makefile (Android.mk) and add locations of missed libs into LOCAL_C_INCLUDES before include $(BUILD_SHARED_LIBRARY) was built. Here is my entire Android.mk:


ifndef GSTREAMER_ROOT_ANDROID
$(error GSTREAMER_ROOT_ANDROID is not defined!)
endif

ifeq ($(TARGET_ARCH_ABI),armeabi)
GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)/arm
else ifeq ($(TARGET_ARCH_ABI),armeabi-v7a)
GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)/armv7
else ifeq ($(TARGET_ARCH_ABI),arm64-v8a)
GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)/arm64
else ifeq ($(TARGET_ARCH_ABI),x86)
GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)/x86
else ifeq ($(TARGET_ARCH_ABI),x86_64)
GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)/x86_64
else
$(error Target arch ABI not supported: $(TARGET_ARCH_ABI))
endif

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := tutorial-3
LOCAL_SRC_FILES := tutorial-3.c
LOCAL_SHARED_LIBRARIES := gstreamer_android
LOCAL_LDLIBS := -llog -landroid

# my addition to fix Android Studio complaints about dependencies

LOCAL_C_INCLUDES := $(GSTREAMER_ROOT)/include
LOCAL_C_INCLUDES += $(GSTREAMER_ROOT)/include/gstreamer-1.0
LOCAL_C_INCLUDES += $(GSTREAMER_ROOT)/include/glib-2.0
LOCAL_C_INCLUDES += $(GSTREAMER_ROOT)/lib/glib-2.0/include

include $(BUILD_SHARED_LIBRARY)

GSTREAMER_NDK_BUILD_PATH  := $(GSTREAMER_ROOT)/share/gst-android/ndk-build/
include $(GSTREAMER_NDK_BUILD_PATH)/plugins.mk
GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_EFFECTS)
GSTREAMER_EXTRA_DEPS      := gstreamer-video-1.0
include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk
