| 11 | +// |
| 12 | +// If you wish to customize it (because you want to manually link a C++ library |
| 13 | +// or pass a custom compilation flag) you can: |
| 14 | +// |
| 15 | +// 1. Copy this CMake file inside the `android/app/src/main/jni` folder of your |
| 16 | +// project |
| 17 | +// 2. Copy the OnLoad.cpp (in this same folder) file inside the same folder as |
| 18 | +// above. |
| 19 | +// 3. Extend your `android/app/build.gradle` as follows |
| 20 | +// |
| 21 | +// android { |
| 22 | +// // Other config here... |
