[Android] How to vibrate the device?

Hi again...

How to vibrate the device or get the native activity?

thx!

You can't with the SFML port as far as I understand.

I also haven't found anything googling it. Well, at least you can always call yourself during gaming.

If you need this feature immediately you could write a JNI wrapper around this API (Do not forget to add the permission for vibration): http://developer.android.com/reference/android/os/Vibrator.html
I don't think there is a native library for it.

Thx all for reply

I did a little hack for Kroniax to get access to the "NativeActivity". Just copy the "Activity.hpp" from the sfml/src/system/android directory to your project and include it in a source file. Then you can use sf::priv::getActivity(nullptr)->Activity to get the NativeActivity.
It's just a hack and I don't know if its a good one, but it worked for my game  (There could be race conditions)

I hope SFML will implement a out of box solution for this.

Can't you simply rely on `sf::Window::getSystemHandle`?

The impl specific to Android is here: https://github.com/SFML/SFML/blob/master/src/SFML/Window/Android/WindowImplAndroid.cpp#L87

No, because you will get the NativeWindow, but you will need the NativeActivity to set up the Java call...


AlexAUT

[CytraL]

Exactly.. getSystemHandle returns ANativeWindow.

[Hiura]

Okay, I was expecting some function to get the activity from a window... too bad.

[AlexAUT]

I don't think something like that exists. The problem is, a user of the NDK need the NativeActivity to get access to the AssetsManager, which is used to load assets 

So maybe we should think of a good way to expose the NativeActivity, so I can drop my hack.


Edit: Created an issue on github: Link
