sf::Keyboard::setVirtualKeyboardVisible crashes on android
« on: February 15, 2016, 05:40:40 pm »
The following code crashes on android since this commit.
#include <SFML/Window.hpp>
int main()
{
    sf::Keyboard::setVirtualKeyboardVisible(true);
}

Backtrace from adb logcat:

The issue seems to be related to this line. Removing that line and thus not deleting the lNativeActivity seems to solve the crash.

Yeah, good find. Doesn't make any sense to delete that reference.

Edit: Created a branch/pull request here.
