I'm trying to build the cornerstone based on AOSP 4.3_r2.2. I got a lot of errors during the building like these: frameworks/base/core/res/res/values/public.xml:244: error: Symbol 'config_bluetooth_adapter_quick_switch' declared with <java-symbol> not defined frameworks/base/core/res/res/values/public.xml:1558: error: Symbol 'config_enableDreams' declared with <java-symbol> not defined frameworks/base/core/res/res/values/public.xml:919: error: Symbol 'ic_suggestions_add' declared with <java-symbol> not defined frameworks/base/core/res/res/values/public.xml:920: error: Symbol 'ic_suggestions

In AOSP9.0.0_r30 's build log, there are clang commands like this: prebuilts/clang/host/linux-x86/clang-4691093/bin/clang++ /OpenSource/Build/Android/9.0.0_r30/soong/.intermediates/bionic/libc/crtbegin_so/android_x86_64_core/crtbegin_so.o @/OpenSource/Build/Android/9.0.0_r30/soong/.intermediates/bionic/libm/libm/android_x86_64_core_shared/libm.so.rsp ...... FYI, it is a linking commmand. In short, it is like: clang++ path_to_file1 @path_to_file2 ...... What does the " @ " mean here? 来源： https://stackoverflow.com/questions/55440501/what-does-mean-in-this-clang-command-in-aosp-build-log

I know, that android.Build.SERIAL is generated at first device boot, but I can't locate where and when exactly. I'm building AOSP Jelly Bean , Android tablet, nosdcard. 2nd question: is this serial number really unique for all Android devices? Alexis C. According to this thread , it clearly says that it's unique, but added since API 9 and may be not present on all devices. If you're writing your app for a specific device's model, you could direclty check if it has an IMEI. Otherwise, as you said, I recommend you to write a custom ID generator module. You will be sure that your ID will be

I am looking for a way to draw text on EGLTexture using Skia library in C/C++. I am planning to run a program that does it on Android platform during bootup before SurfaceFlinger comes up. Please don't point me to Android Java examples as that is not what I am looking for. I am troubleshooting UI issue at frame buffer level. I am looking for a way to do this in C/C++ using Android native libs (Skia etc). I have a sample program that can render an image using SkBitmap onto EGLTexture. I was able to display it on monitor. I followed same example and came up with a strategy like this. But it

I am trying to build the Camera App from AOSP. I am on UBUNTU 14.04. I followed the guide in the official documentation. At the end I execute make Camera I get the following error. ... ... including ./system/media/audio_utils/Android.mk ... including ./system/media/camera/src/Android.mk ... including ./system/media/camera/tests/Android.mk ... including ./system/netd/client/Android.mk ... including ./system/netd/server/Android.mk ... including ./system/security/keystore-engine/Android.mk ... including ./system/security/keystore/Android.mk ... including ./system/security/softkeymaster/Android.mk

I'm working on an Android.mk file in which, for a single module, one of the files needs different CPPFLAGS; namely, it needs -frtti enabled, while others need the Android default of -fno-rtti. The obvious solution was target-specific variables , but oddly they do not seem to affect compilation, even with some fiddling to ensure the values should be fixed at the right time. Here's an extract from my Android.mk (names changed to protect me): LOCAL_MODULE := foo_bar LOCAL_SRC_FILES := \ foo_bar.cpp \ foo_baz.cpp my_intermediates:= $(local-intermediates-dir)/foo_baz.o $(my_intermediates): LOCAL
