I am using video networking library - https://github.com/vimeo/vimeo-networking-java
But unable to play video in my android app. I don't know HTML iframe properly
In the official link, it shows-
Video video = ...; // obtain a video in a manner described in the Requests section
String html = video.embed != null ? video.embed.html : null;
if(html != null) {
// html is in the form "<iframe .... ></iframe>"
// display the html however you wish
}
What code I need to place here. I am unable to understand. If you know?
You don´t need any library to use Vimeo player in Iframe.
Here is an example:
vimeoPlayer.java file:
public class vimeoPlayer extends AppCompatActivity {
private WebView myWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_vimeo_player);
myWebView=(WebView)findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadDataWithBaseURL("https://vimeo.com/47412289","<iframe src=\"https://player.vimeo.com/video/47412289\" width=\"100%\" height=\"100%\" frameborder=\"0\"></iframe>","text/html", "utf-8",null);
}
}
activity_vimeo_player.xml

I am trying to load url inside my custom webview
webview.xml-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView
android:id="#+id/scrollview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none">
<WebView
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</ScrollView>
</RelativeLayout>
and here is my classfile
public class AppDev extends CordovaActivity implements WLInitWebFrameworkListener {
private WebView webview;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
WL.createInstance(this);
WL.getInstance().showSplashScreen(this);
WL.getInstance().initializeWebFramework(getApplicationContext(), this);
webview = (WebView)findViewById(R.id.webView);
}
public void onInitWebFrameworkComplete(WLInitWebFrameworkResult result){
if (result.getStatusCode() == WLInitWebFrameworkResult.SUCCESS) {
// super.loadUrl(WL.getInstance().getMainHtmlFilePath());//
webview.loadUrl(WL.getInstance().getMainHtmlFilePath());
} else {
handleWebFrameworkInitFailure(result);
}}
loading url in webview is producing following error-
com.worklight.common.Logger$UncaughtExceptionHandler
java.lang.NullPointerException
com.worklight.common.Logger$UncaughtExceptionHandler(com.AppDev.AppDev.onInitWebFrameworkCo mplete(AppDev.java:49)
is there anyway to load url in custom webview not in cordova?
Any Help :(
Did you try following the Integrating Server Generated Pages in Hybrid Applications training module and sample application?
The module explains how to bring up a webview and display an external website in it (and return back to the application's webview).
I am trying to load from asset folder. I tried following and googling around. But, my file doesn't load up. It says "Web page not available"
Here is my code:
HelpActivity.java
public class HelpActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_help);
((WebView) findViewById(R.id.webView1))
.loadUrl("file///android_asset/help.html");
}
public void closeWindow(View v) {
finish();
}
}
help.xml
<LinearLayout 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:orientation="vertical"
tools:context=".HelpActivity" >
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
</WebView>
</LinearLayout>
help.html
<html>
<body>
Hello world
</body>
</html>
Should i include any permissions in AndroidManifest?
You're missing a : from your file protocol:
file:///android_asset/help.html
^
WebView mWebVwRehat = (WebView) findViewById(R.id.webView1;
mWebVwRehat.setBackgroundColor(0); // to make webview transparent
mWebVwRehat.loadUrl("file:///android_asset/help.html");
((WebView) findViewById(R.id.webView1)).loadUrl("file:///android_asset/help.html");
I'm trying to build an android app, which just consists of a webview. I took the example from android dev site and modified it. But as simple as it looks, every call to findViewById results in a null pointer.
The .java file:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WebView webView = (WebView) findViewById(R.id.webview);
// returns null pointer
webView.loadUrl("file:///android_asset/index.html");
setContentView(webView);
}
}
The layout file:
<LinearLayout 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"
android:orientation="horizontal"
tools:context=".MainActivity" >
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
And I put following line into the manifest:
<uses-permission android:name="android.permission.INTERNET" />
I'm puzzled ...
Change to
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylayout); // muylayout is your layout.xml
WebView webView = (WebView) findViewById(R.id.webview);
// returns null pointer
webView.loadUrl("file:///android_asset/index.html");
}
}
You need to set the content of your layout to the activity before calling findViewById. findViewById looks for a view with the id provided in the current layout inflated.
Just in case the accepted answer is not working. Since i have two different layouts for phone and tablet but only one have WebView which cause findViewById() get null.
EDIT:
Here's the video showing the problem: www.youtube.com/watch?v=5ZZsuMH5T9k I'm really stuck here :/
--
I have an activity which consists of a webview and a button at the bottom. I set the window of the activity to fullscreen using this code in onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
InstaFetchApplication.applyCurrentTheme(this);
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_PROGRESS);
if (UserPreferences.getIsFullScreenReadingEnabled(this)) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
// this just do this: window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
ActivityUtils.toggleFullScreen(this, true);
}
setContentView(R.layout.view_article);
// ...
}
The problem is that most of the time the webview seems to "push" the button off the screen. Here's the screenshot:
(larger version)
What I would expect to see (and sometimes I do) is here:
(larger version)
Here's the layout I'm using (note that in my app the top layout has to be a RelativeLayout):
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_test"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="#+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Click me!"
/>
<WebView
android:id="#+id/web_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/button"
/>
</RelativeLayout>
I also noticed that if you turn off all animations on the device using system settings, the issue is gone (though there's this glitch when the whole view has a top margin and then it jumps back in the correct position).
Did anyone encounter similar problem and know how to fix it?
Finally I found the answer. Adding WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS flag to the window solved my problem.
See this post: flag_fullscreen + windowNoTitle == button focus bug.
I just added a button to the Hello WebView tutorial, and everything seems to look right. Then I converted main.xml from LinearLayout to RelativeLayout, and everything still seems to look right. I think you are making things too complicated. :-) Try removing most of that initialization code from onCreate() and just specify it in the XML.
Here is my project.

mWebView.goBack();

Try to align the web view to the parent top, and align the button to the parent bottom and to be below the web view. I have found times when, for no real reason, the elements don't quite line up correctly if they are not all strung together in a linear sequence either anchored at the top or at the bottom of the screen.
I presume that you are not overriding the onMeasure() method and changing the measured height of the button. I've created numerous (too many) bugs during development of my apps by miscalculating the height of an element during the layout phase and have spent hours struggling with debugging the layout definition code only to find that it was fine, but the height calculation was feeding invalid data into the layout's rendering phase.
Unless the RelativeLayout is absolutely necessary, You could change to a LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<WebView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="I'm a button"/>
</LinearLayout>
It should give a better result.
To hide the title bar I use:
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Tested on a Galaxy S 2 (Android 2.3.3) and Huawei U8180 X1 (Android 2.2.2) and worked fine with your relative layout.
From the screenshot I have the impression that the problem lies rather with the incomplete progress indicator you requested. The fact that the problem disappears when turning off the animations also supports this theory.
You may try this. The top layout is still RelativeLayout, the only difference with yours is the LinearLayout is wrapping up everything:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_test"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="1">
<WebView
android:id="#+id/web_view"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight=".90" />
</LinearLayout>
</RelativeLayout>
In the LinearLayout, WebView occupies 90% of entire window(and parent) and the button remaining 10%. The height is set to 0px for both, so the weight can do the work for both of them. The cost for the parsing this xml is insignificant.
And in Java code I did:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
requestWindowFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
LinearLayout mLinearLayout = (LinearLayout)findViewById(R.id.ll);
Button mButton = new Button(this);
LinearLayout.LayoutParams mParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, 0, 0.10f);
mButton.setText("Click me!");
mButton.setLayoutParams(mParams);
mLinearLayout.addView(mButton);
mLinearLayout.invalidate();
}
below code might help you,
webView = (WebView) findViewById(R.id.webview1);
webView.setInitialScale(100);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
view.scrollTo(0, 0);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadDataWithBaseURL(null, yourdata, "text/html", "utf-8", null);
// view.loadUrl(url);
return true;
}
});
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
try {
//your stuff
} catch (Throwable e) {
e.printStackTrace();
}
}
}
