In android getting white screen before activity when first time app start on phone

Question

Here is my source code of launcher activity. I search a lot on stack overflow but nothing getting good answer

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_select_lang);

        init();
    }

  private void init(){
        spnLanguage = (Spinner)findViewById(R.id.spnLanguage);
        btnNext = (Button)findViewById(R.id.btnNext);
        btnNext.setOnClickListener(this);

    }

Are you looking to remove the white screen by showing a splash screen? — Elvis Chweya, Oct 19 '16 at 07:41
Do you have class which extends Application? Any configurations? — Sreehari, Oct 19 '16 at 07:41
It may be the cause. As in your activity onCreate I dont see any heavy operations. Guess the same with onResume. Or try with some other devices as well — Sreehari, Oct 19 '16 at 08:41

Android apps do take some amount of time to start up, especially on a cold start. There is a delay there that you may not be able to avoid

In the AndroidManifest file of your starting Activity, mention a transparent Theme

<activity
    android:name="Your activity name"
    android:theme="@android:style/Theme.Translucent.NoTitleBar" >
 <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

In my case delay was bit more. After searching a lot I found that it is because of android studio auto run feature. After disabling the auto run issue is solved.

I had a similar problem some time ago.

The activity is displayed to the user when it reaches the onStart() method. Your init() seems to take some time so until it finishes, you will only see the empty activity.

You could either trigger all heavy background work (that is not needed for the initial GUI setup) in a later method or first call another activity acting as splash screen if you have to keep all content of init() where it is.
