[Java for Android App Development] haloperidollly:
Hello,

I am trying to build an Android Studio project based on a simple example from the web with VideoView. Everything seems OK, the project builds successfully but both in the emulator and on my device it gives an error: "Unfortunately [myapp] has stopped". This is getting really frustrating, I've searched the Internet for similar errors but didn't find any solution to my case. I think the code is ok but there is something with the settings because I imported the project from a web example:

itcuties[dot]com/android/play-video/

Anyway, the code is:

........SelectActivity.java........

package com.itcuties.android.videoplayer;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

/**
* Select video source activity.
*
* @see ITCuties
*/
public class SelectActivity extends Activity implements OnClickListener {

private Button playFromUrlButton;
private Button playOnYouTubeButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_select);

playFromUrlButton = (Button) findViewById(R.id.buttonURL);
playOnYouTubeButton = (Button) findViewById(R.id.buttonOnYouTube);

// Set onClickListener
playFromUrlButton.setOnClickListener(this);
playOnYouTubeButton.setOnClickListener(this);

}

@Override
public void onClick(View v) {

// Check which button was clicked
if (playFromUrlButton.isPressed()) {
Intent i = new Intent(SelectActivity.this, URLVideoActivity.class);
SelectActivity.this.startActivity(i);

} else if (playOnYouTubeButton.isPressed()) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse([B][I]"<Youtbe page>[/I][/B]"));
SelectActivity.this.startActivity(i);
}
}
}

........URLVideoActivity.java........

package com.itcuties.android.videoplayer;

import android.app.Activity;
import android.os.Bundle;
import android.widget.VideoView;

/**
* Play Video from URL
*
* @see ITCuties
*/
public class URLVideoActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.url_activity_video);

VideoView video = (VideoView)findViewById(R.id.videoView);
video.setVideoPath("[I][B]<Address to mp4 file>[/B][/I]");
video.start();
}
}

........AndroidManifest.xml........

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="[I][B]<schemas android link>[/B][/I]"

</manifest>

The error from emulator console:
