I have implemented a web view to play a embedded flv video in my application. And it WORKS! but the problem is video frame is too small.. (video only takes about 1/8 of the screen) How can i make my video fit to screen?
Here's my code
MainActivity.java
package com.example.webvideo;
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
public class MainActivity extends Activity {
private WebView mWebView;
private LinearLayout mContentView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContentView = (LinearLayout) findViewById(R.id.linearlayout);
mWebView = (WebView) findViewById(R.id.webView);
mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
WebSettings webSettings = mWebView.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
mWebView.loadUrl("http://www.fortunagate.com/adaderana_apps/video_player.php?video=http://derana.lk/content/video/SriGauthamaSambuddha24-15thJune2014.flv");
mWebView.setWebViewClient(new HelloWebViewClient());
}
#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;
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.setWebChromeClient(new WebChromeClient() {
private View mCustomView;
#Override
public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
{
// if a view already exists then immediately terminate the new one
if (mCustomView != null)
{
callback.onCustomViewHidden();
return;
}
// Add the custom view to its container.
mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
mCustomView = view;
mCustomViewCallback = callback;
// hide main browser view
mContentView.setVisibility(View.GONE);
// Finally show the custom view container.
mCustomViewContainer.setVisibility(View.VISIBLE);
mCustomViewContainer.bringToFront();
}
});
webview.loadUrl(url);
return true;
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())
{
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}

I think you should have your WebView like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<FrameLayout
android:id="#+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"/>
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</RelativeLayout>
Then, when you want it to appear just change the visibility to visible and it will cover the entire screen.

Basically i have BottomNavigationView activity in that there are 3 fragments (tab1,tab2,tab3) which contain 3 webviews, what i actually wanna to do is while scrolling down the webview my actionbar should hide, likegetSupportActionBar().hide(); i know already there are answers in the stack overflow for the same question, but i don't know what to do in my case, because i am a beginner in android development
here is my activity_main.xml

if (mfloat >= tToolbar.getHeight() && isShowing) {

}
}
});
private void toolbarAnimateShow(final int verticalOffset) {

What's the solution?
When you run the application and view the site does go out when you press the back button
#Override
public void onBackPressed() {
super.onBackPressed();
if(webview.canGoBack()){
webview.goBack();
}
}
Should be
#Override
public void onBackPressed() {
if(webview.canGoBack()){
webview.goBack();
} else {
super.onBackPressed();
}
}
I'm new to app building... I tried to add a progress bar or a loading screen to a practice app but i wasn't successful.
Could you please help and show me how to do it and where to add it in the code.

Thanks in advance,

This is how I have been using it in the past.
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
if (!mProgressDialog.isShowing()) {
mProgressDialog.show();
}
mProgressDialog.setProgress(progress)
if (progress == 100) {
mProgressDialog.dismiss();
}
}
});
Where mProgressDialog is a Dialog where I am showing the progress.
I have created a web view and used a embedded flv video link as for the video link. I was able to play it in my samsung tab but when i try to play it in my samsung phone all is shows is a BLUE LEGO WITH QUESTION MARKS.. What is the reason that i could play it in my tab but not in phone.

Is Flashplayer installed on your Phone?
I had to install an older Flash Version on my Device, as Adobe stopped Support for Android a while ago, FLV Playback in Webview doesn't work with newer Android Versions.
I've built a webview app that works fine.
I've tried to add admob to the bottom on app, but it doesnt show.
I've figured out if I set the main activity to
setContentView(R.layout.activity_main);
I get ad, but no webview
If I set the main activity to
setContentView(mWebview );
I get the webview but no ad.
How can I get both to show together?

Make a pointer to the webView1 ex:

try this:

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mWebview.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
