                                    EventActivity.class);
                            startActivity(i);
                        }
                    }
                });

                    Thread.sleep(200);
                } catch (InterruptedException e) {
                    e.printStackTrace();

Answer 1

Seems like you haven't added EventActivity in AndroidManifest.xml (failed to start activity message in logcat). Make sure you have added the activity in Manifest file.

Answer 2

Problem is Caused by: java.lang.NullPointerException

Here com.example.temp9.EventActivity.onCreate(EventActivity.java:22) in EventActivity class' onCreate function at line 22 location you are accessing some null pointer.
