-===== android method 2 ===== 
- 
-Thank you to everyone for your help. 
- 
-I recently had to build OpenCV for Android from source (because I wanted to link against LLVM libc++ STL instead of GNU STL). In case it’s useful to anyone else, here are some quick instructions on how I did it: 
- 
-<code> 
-    $ mkdir ~/sdk && cd ~/sdk 
-    $ wget https://dl.google.com/android/repository/tools_r25.2.5-macosx.zip && unzip tools_r25.2.5-macosx.zip 
-    $ tools/android sdk 
-    Select and install the following two packages: 
-        Android SDK Build-tools 27.0.3 
-        Android 8.1.0 (API 27) -> SDK Platform 27 
-    $ mkdir ~/opencv && cd ~/opencv 
-    $ git clone https://github.com/opencv/opencv.git 
-    $ cd ~/opencv/opencv 
-    $ wget https://gist.githubusercontent.com/ngriffiths/296e2fc16b8586705712d50bdfe746b0/raw/350a8cb6497bfe367dda75b7bb202d6c7ce09a72/always-use-ant__find_android.patch && git apply always-use-ant__find_android.patch 
-    $ cd platforms/android 
-    $ ANDROID_SDK=~/sdk ANDROID_HOME=~/sdk ./build_sdk.py --config ndk-16.config.py ~/opencv/build 
-</code> 
- 
-I already had the ANDROID_NDK environment variable set to a local NDK 16 installation. 
- 
- 
-One unusual thing I couldn’t work out was why the static libs I built were much larger than those in the official distribution (e.g. my arm64-v8a/libopencv_core.a is 75.8MB vs 7.5MB).
