Black screen appears before splash screen

Question

when I launch my application, there is a black screen that appears for few moments and then only splash screen appears.I followed some of the solutions from this thread but none worked.What might be the actual cause of it? can anyone help? I have pasted the code below.

SplashScreenActivity.java

public class SplashScreenActivity extends Activity {

    private static final int SPLASH_TIME_OUT = 3 * 1000;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_splash);

        Util.doGuestLoginAndCheckForExpireDate();

        UserDetail.deleteUserDetailJson();
        Util.setProfileFetchStatus(false);
        // Start animating the image
        final ImageView splash = (ImageView) findViewById(R.id.logoImageViw);

       final  TranslateAnimation anim = new TranslateAnimation(0f, 0f, 1200f, 0f);
        anim.setDuration(1200);
        anim.setFillAfter(true);

        splash.startAnimation(anim);

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                splash.setAnimation(anim);

                if (Util.getLoginStatus()) {
                    startActivity(new Intent(SplashScreenActivity.this, RestActivity.class));
                } else
                    startActivity(new Intent(SplashScreenActivity.this, AppIntroduction.class));

                finish();

            }
        }, SPLASH_TIME_OUT);

    }
}

This is thetheme I've included in Application tag inside Android manifest.xml file

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/primary_color</item>
    <item name="windowNoTitle">true</item>
    <item name="colorAccent">@color/primary_color</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

Anything Am I doing wrong here??

Check the methods that are called before ImageView Intialization may be they are taking long time to complete their respective task — Jitesh Dalsaniya, Feb 03 '16 at 15:49
@JiteshDalsaniya I tried running an app by commenting all the lines above initialization of image view part , but the problem still persists — ishwor kafley, Feb 03 '16 at 15:56
code inside Runnable's run method put ui update code in runOnUIThread method then check. — Jitesh Dalsaniya, Feb 03 '16 at 15:59
@JiteshDalsaniya inside the run method of handler, I defined runOnUiThread( new Runnable) and placed all code inside its run method, but the problem still exists.May be there is something wrong with the theme I am using?? — ishwor kafley, Feb 03 '16 at 16:10

You´ll see black or white depending on chosen theme till the main activity is created, to reduce the time don´t do anything intense in onCreate just set the layout you can move your code to onStart() or onResume() in the linked thread you also see that he set´s android:windowBackground to set the initial background of the activity while loading, can be static image or color

I had this issue when I updated gradle, I changed it back to prebeta release to fix it. From:

dependencies {
    classpath 'com.android.tools.build:gradle:2.2.0-beta1'
}

To:

dependencies {
    classpath 'com.android.tools.build:gradle:2.1.0'
}
