I am trying to use webView to display an HTML file that is on the device and not the internet. I have my html files in the /Download folder. When I launch the application I get the following error:
Webpage not available
The webpage at file:///storage/sdcard0/Download/manuals/test/index4.html might be temporarily down or it may have been moved permanently to a new web address.
I know the file is there but it will not display it.
Here is my code:
package com.asstechmanuals.techmanual;
import java.io.File;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
private WebView mWebView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
File fileStandard = new File("/storage/sdcard0/Download/manuals/test/index4.html");
File fileNewStandard = new File("/storage/sdcard0/Download/manuals/test/index4.html");
File fileKitKat = new File("/storage/sdcard0/Download/manuals/test/index4.html");
if(fileStandard.exists())
mWebView.loadUrl("file:///storage/sdcard0/Download/manuals/test/index4.html");
else if(fileNewStandard.exists())
mWebView.loadUrl("file:///storage/sdcard0/Download/manuals/test/index4.html");
else if(fileKitKat.exists())
mWebView.loadUrl("file:///storage/sdcard0/Download/manuals/test/index4.html");
else
mWebView.loadUrl("file:///storage/sdcard0/Download/manuals/test/index4.html");
mWebView.setWebViewClient(new vwClient());
}
private class vwClient extends WebViewClient{
@Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.loadUrl(url);
if (url.toLowerCase().contains(".pdf"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(url), "application/pdf");
startActivity(intent);
}
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);
}
@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;
}
}
