Video player not working - Android Studio - java

I am trying to add a video played on button click with android studio.
However, when I click the button a "sorry, this video cannot be played" message box appears on the emulator screen.
Can you help me see where I'm going wrong.
Below is the code I approached the goal with
Trialvideo.java
package android.com.trialvideo;
import android.app.Activity;
import android.graphics.PixelFormat;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;
public class TrialVideoActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/** // Video view: to view our video
VideoView video = (VideoView) findViewById(R.id.surface_view);
//set video path to our video(in this case man-cheetah-gazalle.3gp)
video.setVideoPath("/raw/jeewan.mp4");
video.start();
**/
final Button play =(Button)findViewById(R.id.play);
play.setOnClickListener(new OnClickListener(){
public void onClick(View V){
videoPlayer();
}
});}
public void videoPlayer(){
getWindow().setFormat(PixelFormat.TRANSLUCENT);
VideoView videoHolder = (VideoView)findViewById(R.id.surface_view);
videoHolder.setMediaController(new MediaController(this));
videoHolder.setVideoPath("/TrialVideo/raw/lic.3gp");
videoHolder.requestFocus();
videoHolder.start();
}
}

Hi try the following code:
VideoPlaying.java
public class VideoPlaying extends Activity {
private MediaController mc;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
VideoView vd = (VideoView) findViewById(R.id.VideoView);
Uri uri = Uri.parse("android.resource://" + getPackageName() + "/"+R.raw.VideoName);
mc = new MediaController(this);
vd.setMediaController(mc);
vd.requestFocus();
vd.setVideoURI(uri);
vd.start();
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:gravity="center">
<VideoView android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:id="#+id/VideoView"></VideoView>
</LinearLayout>
place the video on the raw folder and run the code. Sometimes video will not be correctly shown on the emulator, try to check it also on the actual device.

Android does not have a C: drive. You need to put the video file on the device (e.g., copy it to the device's external storage), then supply VideoView with an appropriate path to the file (e.g., using Environment.getExternalStorageDirectory()).

Getting white screen when trying to open the app. App is getting launched on my phone without errors

When I am trying to run my app on my phone it is getting successfully installed in my phone but I am getting white screen instead of my splash page . Attaching my xml code and java code for your reference . Your help is highly appreciated !!

activity_main.java
package com.example.kriova;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(getApplicationContext(),
MainActivity.class);
startActivity(intent);
finish();
}
}
The finish() method is called and the activity destroys and returns to the home screen.
Your code should be like this
package com.example.kriova;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}}
remove the last line which is :-
finish();

I can't figure it out why this simple videoView demo doesn't work

I'm learning how videoView works. I followed a tutorial; this is my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.simoc.videoviewdemo.MainActivity"
tools:layout_editor_absoluteY="81dp"
tools:layout_editor_absoluteX="0dp">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="0dp"
android:layout_marginRight="0dp"
android:layout_marginTop="0dp"
android:layout_marginBottom="0dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<VideoView
android:id="#+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
and this is my mainActivity.java:
<package com.simoc.videoviewdemo;
import android.net.Uri;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoView myVideoView = (VideoView) findViewById(R.id.videoView);
myVideoView.setVideoPath("android.resource://"+ getPackageName()+"/"+R.raw.myvideo.3gp);
//myVideoView.setVideoURI(Uri.parse("http://archive.org/download/ksnn_compilation_master_the_internet/ksnn_compilation_master_the_internet_512kb.mp4"));
//String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/myvideo.3gp";
//myVideoView.setVideoPath(path);
//Log.i("MY_PATH: ", path);
myVideoView.start();
}
}
Ok. First I create a "raw" folder unde "res" and put my video in it. I've set the videoPath and all works fine.
So I decided to try to stream a video. It works the link in the code but it doesn't work a random YouTube link (and I don't understand why).
But the real question is: why this 2 lines:
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/myvideo.3gp";
myVideoView.setVideoPath(path);
are wrong? I put the video in the /storage/emulated/0/myvideo but I always get the error can't play the video. I didn't find a different way to use videoView and so I really don't know where is my fault.
Oh, in the manifest I added the permissons:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
try this don't add extension name
VideoView myVideoView = (VideoView) findViewById(R.id.videoView);
String path = "android.resource://" + getPackageName() + "/" + R.raw.myvideo;
myVideoView.setVideoURI(Uri.parse(path));
myVideoView.start();

ImageViewTouch doesn't display image on DialogFragment

I've found out the ImageViewTouch since I wanted to create a zooming image preview on my app though I need to display that image on one of my DialogFragment. But it works just fine on a normal FragmentActivity which is the MainActivity but not in my DialogImage and I'm not sure why.
I imported the library using the gradle and here's my code so far:
The MainActivity
import it.sephiroth.android.library.imagezoom.ImageViewTouch;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
ImageViewTouch mImage;
#Override
protected void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView( R.layout.fragment_main );
mImage = (ImageViewTouch) findViewById( R.id.image );
ImageDownloader2 imgDownload = new ImageDownloader2();
imgDownload.download("MY_URL", mImage);
Button click = (Button)findViewById(R.id.button);
click.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
showPromoImage();
}
});
}
private void showPromoImage(){
DialogImage promo_details = new DialogImage();
promo_details.show(getFragmentManager(), "promo_details");
}
}
The DialogImage
import android.app.DialogFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import it.sephiroth.android.library.imagezoom.ImageViewTouch;
/**
* Created by Bahay on 2/19/14.
*/
public class DialogImage extends DialogFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_image, container);
getDialog().setTitle("Test");
getDialog().setCanceledOnTouchOutside(true);
ImageViewTouch promo = (ImageViewTouch) view.findViewById(R.id.image);
ImageDownloader2 imgDownload = new ImageDownloader2();
imgDownload.download("MY_URL", promo);
return view;
}
}

The ImageDownloader2 is just a library which downloads the image from the URL then convert it into bitmap. I just made some customizations for this to work with ImageViewTouch.
As for the ImageViewTouch you can see it here:
https://github.com/sephiroth74/ImageViewZoom
For the ImageDownloader2 class you can see it here:
http://theandroidcoder.com/utilities/android-image-download-and-caching/
I just replaced the ImageView with ImageViewTouch for the download method.
UPDATE:
Tried using a normal old-school dialog wherein I use Activity and Intent where I just themed the DialogImage as android:theme="#android:style/Theme.DeviceDefault.Dialog". Output is same where image is not loaded.
Hope someone can help. Thanks!

Opening one screen from another

I am trying to open one screen from another in an Android App. I copied the outline of the following code from a tutorial online and then tried to substitute my own screens. When I try to run the following code, I get a "Force Close" when I click the button on the first screen (the second screen never displays). Can someone tell me what I am doing wrong? There are four files: ScreenTestActivity.java, main.xml, screen2.java and screen2.xml.

Button b = (Button) findViewById(R.id.btnClick);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
