Question

I am using the WebView of Android so that I will not have to program the zoom and scroll. I have the web page that I want in the assets folder and here is my code. Each time I run in the emulator I am getting the error, no such file or directory. My question is what do I need to change in order for this to work?

Just updated my .java to this and now I receive a force close when I press button1 and my XML is the same as below.

OK I fixed that last part and now all that is happening is I get a blank screen once the app is opened.

package com.DS;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;

public class CheatMathActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);


final Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener(){
    public void onClick(View v){

            WebView webView = (WebView) findViewById(R.id.webView);
            webView.getSettings().setJavaScriptEnabled(true);
            webView.getSettings().setBuiltInZoomControls(true);
            webView.getSettings().setSupportZoom(true);
            webView.loadUrl("file:///android_asset/stuffyoumustknowcoldforapcalc.htm");

    } });  
} 

}    

Ok Here is my XML, before the added WebView I had somewhat of a home activity that had two buttons and a textview, once I add the WebView all that the graphical layout shows is a grey screen that says WebView in the center.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:gravity="center_horizontal"
android:orientation="vertical"
android:background="#4876ff" >
<Button
    android:id="@+id/button1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_marginTop="90dp"
    android:textColor="#0000ff"
    android:text="AP Calculus" />
 <Button
    android:id="@+id/button2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/button1"
    android:layout_marginTop="38dp"
    android:text="More Coming Soon!" />
<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/button2"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="87dp"
    android:textColor="#FFFAFA"
    android:text="If you have any questions or want to report a bug, feel free to email                        me at [e-mail]
                    Thank you!" />
<TextView
    android:id="@+id/titleView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="37dp"
    android:gravity="center_vertical"
    android:text="Welcome to Math Cheat Sheet!"
    android:textAppearance="?android:attr/textAppearanceLarge" />
<WebView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />
</RelativeLayout>

Put a webview on your layout. and on your activity load your html asset like this.

webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.loadUrl("file:///android_asset/stuffyoumustknowcoldforapcalc.htm");

And don’t forget to put file stuffyoumustknowcoldforapcalc.htm in folder named assets.

package com.DS;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.view.View;
import android.widget.Button;
import android.webkit.WebView;

public class CheatMathActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    final Button button1 = (Button) findViewById(R.id.button1);
    button1.setOnClickListener(new View.OnClickListener(){
        public void onClick(View v){

                webView = (WebView) findViewById(R.id.webView1);
                webView.getSettings().setJavaScriptEnabled(true);
                webView.getSettings().setBuiltInZoomControls(true);
                webView.getSettings().setSupportZoom(true);
                webView.loadUrl("file:///android_asset/stuffyoumustknowcoldforapcalc.htm");

        } });  
    } 


}
