Android splash screen Qt 5.5

[unclebenedict]

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

<activity
android:name="org.stir.extension.SplashActivity"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Black.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

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.
