YouTube only plays audio in WebView

YouTube only plays audio in WebView - android

https://drive.google.com/open?id=12rzhjzYvWTKGIQhlhP5OSCINhOAWCU73I want to show audio and video from YouTube using a Web View in Android, but on my mobile device I have a black screen while the video is playing. Audio is playing normally.
I give you two codes, one code that successfully displays audio and video (code 1). the second code (code 2) only successfully displays audio. why this happened? even though there isn't any change just the source of the different you_tube pages
code 1 :

You have to declare progress bar global and declare in OncreateView like this.
import android.content.Context;
import android.graphics.Bitmap;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
import android.view.KeyEvent;
/**
* A simple {#link Fragment} subclass.
*/
public class Home_Fragment extends Fragment {
public ProgressBar bar;
public WebView mwebView;
ProgressBar bar;
public Home_Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_home_, null);
bar=(ProgressBar)rootView.findViewById(R.id.progressBar);
view.loadUrl("https://mbasic.facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
//bar=(ProgressBar)rootView.findViewById(R.id.progressBar);
return rootView;
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#Override
public void onPageStarted(final WebView view, final String url, final Bitmap favicon) {
bar.setVisibility(View.VISIBLE);
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
bar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
}
}
Check my code Hope this helps.:)

ProgressBar bar;//declare as global
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home_, null);
WebView view=(WebView) rootView.findViewById(R.id.webView);
bar=(ProgressBar) rootView.findViewById(R.id.progressBar);
view.loadUrl("https://mbasic.facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
return rootView;
}

Have a look at this solution
public class Home_Fragment extends Fragment {
public ProgressBar bar;
public WebView mwebView;
private View rootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
rootView = inflater.inflate(R.layout.fragment_home_, null);
bar=(ProgressBar)rootView.findViewById(R.id.progressBar);
WebView view = (WebView) rootView.findViewById(R.id.webView);
view.loadUrl("https://mbasic.facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
return rootView;
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#Override
public void onPageStarted(final WebView view, final String url, final Bitmap favicon) {
bar.setVisibility(View.VISIBLE);
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
bar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
}
}

method findViewById does not belong to the class MyWebViewClient where you are trying to access it.
to fix this problem, you need to keep the reference or ProgressBar in the fragment and then access it from MyWebViewClient.
change your code to:
package com.fb.jaisonjoseph.facebookbasic;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
/**
* A simple {#link Fragment} subclass.
*/
public class Home_Fragment extends Fragment {
public ProgressBar bar;
public WebView mwebView;
public Home_Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_home_, null);
WebView view = (WebView) rootView.findViewById(R.id.webView);
view.loadUrl("https://mbasic.facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
bar=(ProgressBar)rootView.findViewById(R.id.progressBar); //uncomment this
return rootView;
}
private class MyWebViewClient extends WebViewClient {
// ProgressBar bar=(ProgressBar)findViewById(R.id.progressBar); Not needed
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#Override
public void onPageStarted(final WebView view, final String url, final Bitmap favicon) {
bar.setVisibility(View.VISIBLE);
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
bar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
}
}

Here is my main activity code, I don't know where I am doing it wrong. Every time I open the app, the web view launches a browser, the apps did not load the web page, it only loads in the browser and I don't want this.

I believe you need to set your WebView client before you call loadUrl().

try this code
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class Main extends Activity {
private WebView mWebview ;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );
}
}

How to load a webpage into webview in android app?

I am trying to make a simple android app that loads a webpage into a WebView.
package com.example.abhi.molinahealthcare;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Molina_HealthCare extends ActionBarActivity {
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_molina__health_care);
WebView myWebView = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new MyWebViewClient());
openURL();
}
private void openURL() {
webview.loadUrl("http://www.google.com");
webview.requestFocus();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_molina__health_care, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
ACTIVITY:-
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
I was not able to open it. I have the INTERNET permission declared in the AndroidManifest.xml

You are not initializing webview object of WebView which you are using in openURL method. do it by initializing webview instead of myWebView in onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_molina__health_care);
webview = (WebView) findViewById(R.id.webview);
...

Why "OnClickListener" is not working

I can't understand why this simple code is not working.
This code suppose to set the color of the button's text to blue, that's all.
I only added to a new created project the lines :
final Button btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Perform action on click
btn.setTextColor(Color.BLUE);
}
});
The full code :
package com.example.b;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
public class MainActivity extends ActionBarActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Perform action on click
btn.setTextColor(Color.BLUE);
}
});
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
}

Most likely the button is in the fragment and not the activity. If so, move your findViewById and your setonclick code into your PlaceHolderFragment.

Android:ActionBarActivity findViewById return NULL

I can't to get the button from fragment, what's wrong?
Recieve a uncaught exception - nullpointerexception;
Button can't be found.
Early all will be find, but after update android sdk, all is changed ((
package com.example.test;
import java.io.IOException;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements OnClickListener {
Button play, pause;
MediaPlayer mplayer;
RadioGroup rgroup;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("MyTAG", "1");
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
mplayer = new MediaPlayer();
rgroup = (RadioGroup) findViewById(R.id.radioGroup1);
play = (Button) findViewById(R.id.play);
pause = (Button) findViewById(R.id.pause);
play.setOnClickListener(this);
pause.setOnClickListener(this);
}
#Override
public void onClick(View v) {
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
return rootView;
}
}
}
p.s. sorry for my english

You are trying to search inside Activity's layout, and your widgets are inside a Fragment's layout.
Put your logic inside your PlaceHolderFragment class:
public static class PlaceholderFragment extends Fragment implements OnClickListener {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
mplayer = new MediaPlayer();
rgroup = (RadioGroup) rootView.findViewById(R.id.radioGroup1);
play = (Button) rootView.findViewById(R.id.play);
pause = (Button) rootView.findViewById(R.id.pause);
play.setOnClickListener(this);
pause.setOnClickListener(this);
return rootView;
}
#Override
public void onClick(View v) {
}
}
P.S. Салам алейкум =)
