I'd like to ask you help about the basics of adding a new HAL (gralloc) lib
to AOSP.
I've received the source code from the developers I mentioned below, but
I'm having troubles integrating it for the final build. The build succeeds,
but I have unexpected behaviour on the real device.
First, I compiled leaving the default gralloc in place, so that I had both
libgralloc.so and libgralloc.emxx.so built ("emxx" is the device name).
Installing this buil on the deice, screen was shown but flashing repeatedly
at each image refresh or update.
So I thoght about removing the default gralloc from the build, by
commenting out (in hardware/libhardware/Android.mk) the "modulesgrallc"
line, like below:
----------------------------
diff --git a/Android.mk b/Android.mk
index 967a096..7857b61 100644
--- a/Android.mk
+++ b/Android.mk
@@ -32,7 +32,6 @@ LOCAL_MODULE:= libhardware
include $(BUILD_SHARED_LIBRARY)
include $(addsuffix /Android.mk, $(addprefix $(LOCAL_PATH)/, \
- modules/gralloc \
tests \
))
-
----------------------------
This way I get these libs:
----------------------------
cd out/target/product/emev/
find . -name "*gralloc*so"
./obj/lib/gralloc.emxx.so
./obj/SHARED_LIBRARIES/gralloc.emev_intermediates/LINKED/gralloc.emxx.so
./symbols/system/lib/hw/gralloc.emxx.so
----------------------------
That didn't solved my problem, but the issue has now shifted to something I
don't understand. With this new build, I can reach the init stages on the
device and also connect to it with "adb shell". So, I can look at logcat,
which keeps looping into the crash I report below.
The critical message I think is:
E/FramebufferNativeWindow( 1425): Couldn't get gralloc module
which I don't understand.
What could I be missing in my build?
