I am new to eclipse/Java. I searched for answer but nothing solved my problem. I hope someone can guide me. I am attempting to launch a webpage withing an android application however I am getting a blank page in the Android Virtual Emulation.

Here is my code 

package com.example.t4;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.webkit.WebView;

public class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    WebView myWebView = (WebView) findViewById(R.id.webview);
    myWebView.loadUrl("http://www.google.com");
  }

  @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;
  }
}

Here is the AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.t4"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.t4.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
   </application>

   </manifest>

and here is the activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<WebView 
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>

</LinearLayout>

I am not sure what I am doing wrong. The code runs without an error. I just get a blank screen. Any help is much appreciated. Thanks in advance.

  • Can you check if your AVD is on-line? Just go to the browser and try to go to google.com or some other random page. – DrkStr Mar 14 '14 at 14:30
  • Thanks for the suggestion. I opened the AVD and just have a blank page. None of the buttons are doing anything. I am really new to this so bear with me. Can you guide me more? – user3420186 Mar 14 '14 at 15:52
  • I clicked the 'home' button it did nothing. or any other button for that matter, – user3420186 Mar 14 '14 at 15:52

    Your AVD has not loaded yet. That is you problem. depending on your computer it can take upto 15 mins. – DrkStr Mar 14 '14 at 16:04
  • Thanks DrkStr. You are right it took a while for it to load. I can see the AVD. I got a red border around the screen and now I am waiting to see if the app loads. so far nothing. I will step out and check back in 1 hour. – user3420186 Mar 14 '14 at 21:27
  • Hi, I dont know what emulator you are using at the moment(in eclipse), but depending on the computer you have you can use this to get a mroe faster and more responsive AVD. https://www.youtube.com/watch?v=xea3Ng-cwwg – DrkStr Mar 15 '14 at 04:46
  • Thanks. Successfully running the app now on my android device. I am skipping the ADV. I just need to figure out how to make pdfs open in pdf capable app or inside my app. – user3420186 Mar 15 '14 at 13:10

try to put myWebView.getSettings().setJavaScriptEnabled(true); // enable javascript

myWebView.loadUrl("http://www.google.com");

  • Thanks. Did that. Run it. Still a blank screen. Any other ideas? – user3420186 Mar 14 '14 at 14:54
  • yes also put this code myWebview.setWebViewClient(new WebViewClient() { public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { // do something here } }); – Lucian Novac Mar 14 '14 at 14:56
  • Thanks Lucian. I am not sure how to use the code that you wrote. I copied and pasted and got errors. I was able to fix one error by changing myWebview.setWebViewClient to myWebView.setWebViewClient (changed the v to Captial V in myWebView). The errors are many errors and I am not sure where to start. Do you I need to import anything else? – user3420186 Mar 14 '14 at 15:46

  • The ADV machine is really slow. Ended up running it on my Android device. Worked but asked me to select which application to open in and I opened the URL in browser. partial success. – user3420186 Mar 15 '14 at 06:30
  • Got it working using WebView theWebPage = new WebView(this); setContentView(theWebPage); theWebPage.loadUrl("http://www.example.com"); – user3420186 Mar 15 '14 at 06:34

Check out this working basic webview. I tested with "www.google.com" like yours and came up with a blank view. I used "http://www.google.com" and it ran fine. Try that out on yours? But feel free to steal the sample code too.

Restart your app (I mean click Run again) and make sure you have enabled javaScript as mentioned above.
