I have an html file in my website:
http://manizani.ir/hamyar_gas_php/map/map_app.html
I want to show it on my Android Application. I created an Activity and use a Webview to load above url. But nothing is loaded and it shows me just an empty activity.
I can load any other web pages successfully, but not about my url.
Please help me to solve it.
Thanks a lot

Mapbox use WebGL and may be is not support on your device.
webview log :

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);
}
}

there are two webviews in scrollview.
<ScrollView>
<LinearLayout>
<WebView></WebView>
<WebView></WebView>
</LinearLayout>
</ScrollView>
I want to make two webviews looks like one webpage. currently, my solution is make webview's height equal to webview's contentHeight. and disable scrollability of webview. but for very big html. it's not a good solution. webview has to render the whole html. I want to use nestedscrollview. make two webviews' height equals to nestedscrollview's height. but I dont known how to deal the events.
Try this to make two WebView looks like one webpage.
public class MainActivity extends Activity {
String url = "http://www.yahoo.com";
String url1 = "http://www.google.com";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("MainActivity", "Activity one");
WebView webview = (WebView) findViewById(R.id.webView1);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewController());
webview.loadUrl(url);
WebView webview2 = (WebView) findViewById(R.id.webView2);
webview2.getSettings().setJavaScriptEnabled(true);
webview2.setWebViewClient(new WebViewController());
webview2.loadUrl(url1);
}
}

WebView client

return true;
}
}
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 new to android development and i'm doing a an app where i need to embed an iframe in android's webview..
iframe sample is
<iframe src="//e.infogr.am/chart-61108188168" width="550" height="680" scrolling="no" frameborder="0" style="border:none;"></iframe>
Can you just set up a simple webview pointing to the iFrames url like so?
Create a webview in the xml:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
Then in your code set it up as:
public class WebActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webcontent);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://websitesby.projectcaruso.com/");
}
}
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>

Hello world

</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");
