Hello.

Currently I control screen by screen the type of internet connection to which the user is connected or not.

I use a method similar to this:

    /*Check conection*/
        ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
        //For 3G check
        final boolean is3g = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE)
                .isConnectedOrConnecting();
        //For WiFi Check
        boolean isWifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
                .isConnectedOrConnecting();

        if (!is3g && !isWifi){

            Toast.makeText(AgendamentoActivity.this, "Sem conexão!! Verifique...", Toast.LENGTH_LONG).show();
            finish();

}

I would like to know how I could create a single class for this and call it in Activity that I need to control it.

I do not have much experience in this and even found some models but I did not quite understand.

I'm using the OpenGL lib, but in compiling the gcc is returned undefined reference, could anyone help? Why is the Activated event triggered more than once?

Just create a normal class with this method, and call in the constructor:

public class Conexao {
    private boolean wifi;
    private boolean movel;

    public Conexao() {
        verificarConexao();
    }

    public boolean getWifi() {
        return wifi;
    }

    public boolean getMovel() {
        return movel;
    }

    private void verificarConexao() {
       ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
        //For 3G check
        movel = manager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnectedOrConnecting();
        //For WiFi Check
        wifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting();

        if (!is3g && !isWifi) {
            Toast.makeText(AgendamentoActivity.this, "Sem conexão!! Verifique...", Toast.LENGTH_LONG).show();
            finish();
        }
    }
}

When you install, you will assign the true or false to the variables, then just get the
