I used the following code to download a file. It runs fine, but when I click the download button, the following error comes: “Application mibooks has stopped unexpectedly.”
How can I solve this problem in my code?
package mds.mibooks;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.DownloadListener;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
public class mibooks extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.webview);
WebView myWebView = (WebView) findViewById(R.id.webView1);
WebSettings webSettings = myWebView.getSettings();
WebView myWebView1 = (WebView) findViewById(R.id.webView1);
myWebView1.setWebViewClient(new WebViewClient());
webSettings.setJavaScriptEnabled(true);
/* WebView webView = (WebView) findViewById(R.id.webView1);
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
*/
// String summary = "<html><body>You scored <b>192</b> points.</body></html>";
// myWebView1.loadData(summary, "text/html", "utf-8");
myWebView1.loadUrl("http://www.mibooks.com/beta/");
myWebView1.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("www.google.com"));
intent.setType("*zip*");
startActivity(intent);
}
});
}
});
}
}
Android application stopped unexpectedly it is normal scenario in android programming when any runtime error is occurred. i was not aware of this when i was throwing this question. I got solution for this problem that is..
1. setContentView(R.layout.webview); and setContentView(R.layout.main); one layout is point to null.
