Adding/Compiling/Linking Halide for Android Studio on Windows

[guayabas]

Hello,
I have been trying to add Halide into an Android app I am creating. Can you help me pointing me the best practice to add Halide into a native code of Android Studio.

Some clarifications of what I have been trying so far:

1. Downloaded the pre-compiled version of Halide from https://github.com/halide/Halide/releases. I am able to build and link fine in my Android app for arm64-v8 but once the app is running I am getting the error

libc++.so is too small to be an ELF executable

from Java code.

2. I added Halide directory from https://github.com/halide/Halide and tried to compile it directly in my Android Studio project with the extra gradle file

externalNativeBuild {
cmake {
targets 'Halide'
}
}

but the Android Studio IDE hangs. I am able to use other libraries that have standard CMakeLists.txt files.

3. Tried the app folder from the Halide repo (https://github.com/halide/Halide/tree/master/apps) that contains the projects HelloAndroid, HelloAndroidGL, HelloAndroidCamera2 but I am getting the following error

I am not really experienced with Android Studio IDE but I do have understanding of CMake and Compiling using Visual Studio/gcc/etc. so any help about how to incorporate Halide will be great

Last thing, my setup is the following:

• OS - Windows 10
• Android Studio - Version 3.5.3
• Phones to test - Samsung Galaxy S10+, Google Pixel 2XL
• NDK - Version 21.0.6113669

Thanks (:

I am able to use other libraries that have standard CMakeLists.txt files.

We do not currently have a standard CMakeLists.txt. I hope this issue will be fixed automatically by #4644 . When that lands, the target will be Halide::Halide.

ic ... alright, thanks for the pointer (: ... good luck generating that standard CMakeLists.txt
