问题
I have a project with C++ code (JNI) and lots of build variants and combinations. These are used to implement different brandings / flavors of the app (i.e. colors, styles, icons, ...).
For example there could be build variants for n customers :
customerNDebug
customerNDebugproguard
customerNRelease
.
Anyway, the C/C++ layer is the same for each product flavor.
Normally CMake in Android Studio compiles C code for every build variant. This makes sense if you have build variants like "debug
" and "release
" where the resulting code actually differs. However, for the build variants I have, the compiled output is always the same.
At the moment the compilation of C/C++ code is done using an external tool in our project and I want to compile using CMake in Android Studio only for proper IDE support of C/C++ code. So for me a single build would suffice.
Is it possible to tell Android Studio to build C/C++ code only once, no matter the build variants and flavors?
回答1:
By default, Android Studio IDE together with CMake and Gradle will generate a series of native build tasks named with externalNative<BuildVariant>Build
according to your build types and flavours. If you want to twist this behaviour, some workaround is as below:
- Create an Android Studio module project which only builds your native code, e.g.
shared-native
. - Let the rest of your modules dependent on this project.
For this solution, you need to consider below points:
- Put your
.so
files into a proper location that other projects can see and link with. - You can only include
debug
andrelease
build types for thisshared-native
module project to avoid too many times of re-build. Or you can simply to let your other projects depends on the release type so that it will be built only ONCE.
