public class timerTime extends AppCompatActivity {
 
    /** timer */
    private static Timer timer;
    private static TimerTask timerTask;
    private final static Handler handler = new Handler();
 
    private static Context mCtx = null;
 
    public timerTime(Context ctxt){
        this.mCtx = ctxt;
    }
 
    public void startTimer(){
        Log.i("startTimer()","start 30000");
        timer = new Timer();
        loadTimer(/*theContext*/);
        timer.schedule(timerTask,30000);
    }
 
    public void startTimer(int time){
        Log.i("startTimer()","time => "+time);
        timer = new Timer();
        loadTimer();
        timer.schedule(timerTask,time);
    }
 
    public static void stopTimer(){
        if (timer != null) {
            Log.i("stopTimer()","stop");
            timer.cancel();
            timer = null;
 
        }
    }
    public void loadTimer(){
        timerTask = new TimerTask(){
            public void run(){
                handler.post(new Runnable(){
                    @Override
                    public void run() {
                        stopTimer();
                        Intent i = new Intent(mCtx, MainActivity.class);
                        startActivity(i);
                    }
                });
            }
        };
    }
}

            }
        }
    };
}

et dans le log quand il crash

Citation:

java.lang.NullPointerException: Attempt to invoke virtual method 'android.app.ActivityThread$ApplicationThread android.app.ActivityThread.getApplicationThread()' on a null object reference
tools.timerTime$1$1.run(timerTime.java:71)

qui est :

Code:

Intent i = new Intent(mCtx, MainActivity.class);

une idée?
