Android-приложение вылетает после всплеска экрана

Question

Я могу загрузить заставку, но через 3 секунды приложение отключится. Я хочу загрузить главную активность после экрана всплеска. Также я обнаружил, что тот же самый раздел обсуждался ранее в стеке но это мне не помогло.

Пожалуйста, помогите мне решить проблемы.

I had recently started another project with same code with different package com.example.jarvis.digin I assure you that there is no compilation errors.

Answer 1

Ошибка в журнале говорил, что это было вызвано б y:

IllegalStateException: вам необходимо использовать тему Theme.AppCompat (или потомок) с этим действием.

Я предполагаю, что существует проблема с темой, указанной в вашем AndroidManifest.xml. Попробуйте изменить его на что-то вроде:

Android: темы = "@ андроид: стиль/Theme.Holo"

Answer 2

new android.os.Handler().postDelayed(new Runnable() { 

     /* 
     * Showing splash screen with a timer. This will be useful when you 
     * want to show case your app logo/company 
     */ 

     @Override 
     public void run() { 
      // This method will be executed once the timer is over 
      // Start your app main activity 
      Intent i = new Intent(SplashScreen.this, MainActivity.class); 
      startActivity(i); 


     finish(); 
     } 
    }, 3000); 

Answer 3

Это сообщение об ошибке при запуске на устройстве

This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

Проблема ясно из сообщения выше.

Я решил удалить это, удалив следующий код с MainActivity.java.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
setSupportActionBar(toolbar); 

Надеюсь, что этот ответ поможет новичкам, когда они выберут пустой шаблон.
