Android splash screen Qt 5.5

This is not questions, this answer for me and other users. After start Qt application on android we see black screen, app icon and app name, in process load. For a production this is not be good. Solutions, splash screen. But change AndroidManifest.xml and uncomment

<meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>

not help for me. Because i see for half seconds, black screen, logo, title app (preload).

What i do.

Change AndroidManifest.xml

add

for a main activity. And uncomment

<meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>

now we have tow splash screen.

SplashActivity.java code

package org.stir.extension;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import android.util.Log;

import android.widget.LinearLayout;
import android.widget.ImageView;
import android.view.Window;
import android.view.WindowManager;

public class SplashActivity extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
Thread logoTimer = new Thread()
{
public void run()
{
try
{
sleep(500);
startActivity(new Intent("org.stir.extension.AndroidExtension"));
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
finish();
}
}
};
logoTimer.start();
}
}

SplashActivity run is app activity. We have tow splash screen. If you splash image in SplashActivity and QtActivity will be different. Change QtActivity::onCreate

//getWindow().setBackgroundDrawable

and set you resize bipmap. Now i have perfect app preload. Sleep after start activity is not good, but so far i can`t find best solutions.
