php-wasm VS ndk-samples

Something closer to “native“ (although still not native) would be an electron app with php interacting with the dom using something like php-wasm https://github.com/seanmorris/php-wasm. Now THAT would be incredible to interact with the ui (dom) without writing any JavaScript, all php.

(And yes, php for browser exists https://github.com/seanmorris/php-wasm )

Presumably more trouble than normal options are worth, but you can also run PHP code in your browser directly using WebAssembly, like https://github.com/seanmorris/php-wasm does. You’ll still have to write normal front end stuff for the visualizations, but this saves you needing to run a server (in theory…I’ve never tried it)

There's work being done with wasm, e.g. php-wasm, but I haven't used it and don't know how well it works etc.

https://developer.android.com/ndk. Java/Kotlin for the rest.

Best you can do is refer to the official samples and learn by taking one of the samples and modifying it to your use case. The comments in the samples should be quite adequate.

You can compile c++ for android using the NDK.

Mobile has a lot of C++ as libraries but in https://developer.android.com/ndk for android.

Then please provide references that say how to do this. Here https://developer.android.com/ndk it says:

cinterop is only for Kotlin/Native, where the whole application gets compiled to native code. If the target is Android, you want to use Native Development Kit (https://developer.android.com/ndk) instead.

It's a little convoluted since the app does still fork from the zygote with ART in there, but they added an entire layer of APIs so you can jump right in from C++. Here's a sample https://github.com/android/ndk-samples/blob/master/native-ac...
