When you are using Android Studio and add a new Activity try:
File -> New -> Activity -> Basic Activity
Then it has the ActionBar configurated by default.

Shared Elements Transition won't work correctly when layout background is set

I tried to follow some tutorials on how to set up a shared elements transition. Though when i try to set up a background the shared element kind of glitches the wrong way and then moves like it should.
Heres a link to a video of my problem: https://drive.google.com/file/d/14lTFGIpqnMwM2MEbLxwBe_gkI0GuyuMc/view?usp=sharing
When no background is set: https://drive.google.com/open?id=15Hpkj7y8nLLTXa5RF5FV00jlTTWMofjF
When i don't set a background in my xml layout, the animation works properly. Does anyone know, why this happens?

You can wrap your shared view (either text1 or text2) in FrameLayout - but still TextView should be the shared element. It should solve the issue.

No Visible Icons on Action Bar (Android Programming)

I have searched the forums and discovered that using app:showAsAction is a recommendation for my question. However, I am using app:showAsAction and still cannot get my icons to display on the action bar. ALSO, I have to set my actionbar title manually in my Main.java because when using xml, the title does not appear on the actionbar. QUESTION: How do I get my icons to appear on the action bar and why can't I set my action bar title in xml? Are these issues related? Here is my code:

How do I get my icons to appear on the action bar
Extend from AppCompatActivity, not Activity
Hook the toolbar up to the Activity by calling setSupportActionBar(myToolbar);
why can't I set my action bar title in xml
Adding app:title="My Title" in your XML should work.

The first problem is that you don't have a Toolbar view in the second activity, while you have it in the first activity.
Try to add also to the second one.

Android Studio error after splash

I have followed and tutorial for 4 times to make a splash screen but after the splash screen the app gives an error and closes. The splash screen has an image which stays for 4 second and the next screen has an webviewer, above the viewer the title bar needs to be there .Any idea?
Android Honey Comb 3.0 is set as default
The Splash.java :
package nl.broodje.app.broodje;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
/**

public class Splash extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
Thread myThread = new Thread(){
#Override
public void run() {
try {
sleep(3000);
Intent startMainScreen = new Intent(getApplicationContext(), MainActivity.class);
startActivity(startMainScreen);
finish();
} catch (InterruptedException e) {
e.printStackTrace();
}
}

myThread.start();
}

}
The AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar" >

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity"/>
</application>
</manifest>

Since MainActivity extends AppCompatActivity, and you're setting your own ActionBar, MainActivity needs to have a NoActionBar theme, like the splash screen.
<activity android:name=".MainActivity"
android:theme="#style/AppTheme.NoActionBar" />
