I develop an app with WebView and Html5, It works, clicking a link in the webpage goes to the next page in the html file inside my app. But when I click the phone's back button, it give me this error : Unfortunately, APPNAME has stopped. I want to go back to the previous page in the website instead.
The website build with : https://github.com/01org/appframework
MainActivity.java

import android.view.KeyEvent;

private WebView WebView;
//Back Button Code
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (WebView.canGoBack()) {
WebView.goBack();
} else {
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}

First,
Check if WebView is null.. rename the global variable to webView (private WebView webView;) and in onCreate change WebView webView=(WebView) findViewById(R.id.webview); to webView=(WebView) findViewById(R.id.webview);
You could also try moving the back button handling code to
#Override
public void onBackPressed()
{
....
}
instead of
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
...
}
as in:
#Override
public void onBackPressed()
{
if (webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
as mentioned in https://developer.android.com/training/implementing-navigation/temporal.html#back-webviews

I'm a rookie at android, trying to make webapp, by following a tutorial.
However, when installed a signed apk, after opening it gives a blank page. have no idea what went wrong.

All i did was follow that tutorial, as i mentioned, it gives a blank page on running the signed APK.
Any help on this is greatly appreciated.
I think you should loadUrl after all.
because settings/configs must apply before loading page.

How to go back to previous page if back button is pressed in WebView?
(18 answers)
Closed 5 years ago.
I have a mirroring of a website in WebView and I would like that when I press the ** Back ** button on the Smartphone, I would go back to the previous page. Currently if I press the ** Back ** button on the Smartphone, the application is minimized (It stays in the background).
I do not know how to do this, can anyone help me?

Override the onBackPressed method in your activity as below:
#Override
public void onBackPressed(){
WebView wv = (WebView)findViewById(R.id.webview1);
if(wv.canGoBack()){
wv.goBack();
} else {
super.onBackPressed();
}
}
Use the above method inside your class, not outside.
public class MainActivity extends AppCompatActivity {
//onCreate method
//onBackPressed method
//other methods
}
Use this .
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && webView.canGoBack()) {
webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
Add wv as global data
private WebView wv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wv = (WebView) findViewById(R.id.webview1);
wv.loadUrl("https://www.xxxxx.com.br");
wv.setWebViewClient(new WebViewClient());
WebSettings ws = wv.getSettings();
ws.setJavaScriptEnabled(true);
ws.setSupportZoom(false);
}
I'm trying to achieve this: MKyong - WebView.
To get a hint at what exactly, then take a look at the last picture before "Download Source Code".
My applications code is:
bookingView = (WebView) findViewById(R.id.fullscreen_content);
bookingView.getSettings().setJavaScriptEnabled(true);
bookingView.loadUrl("http://www.google.com");
But what that code does is opening the url(in this case Google) inside the default browser/internal browser in android and it's not meant to be that in the android application I am making.
Any ideas?
Add this line before the loadUrl() call
bookingView.setWebViewClient(new WebViewClient());
This is the answer:
Features
Load a URL on WebView
Open another page in the website on Webview dont on local Browser.
If you press on backbutton will go to the before page dont out of app.

Im new to android development and am having trouble understanding the error messages. HELP!
If I'm doing anything else wrong, I would love that feedback too :)
EDIT
I moved the swipe refresh layout code to
layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swipe_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</android.support.v4.widget.SwipeRefreshLayout>
I had to change
mWebView = new WebView(this);
to
mWebView = (WebView) findViewById(R.id.webView);
And I had to add the following between the SwipeRefreshLayout xml in the main.xml file.
<WebView android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView"
android:layout_alignParentTop="true"/>
I have set SwipeRefreshLayout refresh listener into onResume. It worked for me.
I know there are a lot of similar questions and believe me, I tried a lot, but nothing worked out for me. I have a Android App which uses a Webview. You can find my App in the Play Store:
https://play.google.com/store/apps/details?id=at.rk.rps&feature=search_result#?t=W251bGwsMSwxLDEsImF0LnJrLnJwcyJd
After a few month in the Play Store I decided to make an update and to use the Android Design Guidelines for my new Design, so a Actionbar was necessary. I went with ActionbarSherlock and everything is fine, except the Webview is now reloading every time I rotate the phone. In my last version I handled this problem with this answer and it worked:
My Webview Reloads When I Change From Portrait To Landscape
But now it won't work again. I have tried that solution too: (I also left a comment at the end of the site)
http://www.devahead.com/blog/2012/01/preserving-the-state-of-an-android-webview-on-screen-orientation-change/
With the same disappointing result. I'm not even sure if ActionbarSherlock is the problem, because I've changed a lot, but it is impossible to recreate the old state!
This is what the App looks like (This is only in the new version implemented, you can't find it in the version which is publish on the Play Store):

I found the answer here:
https://stackoverflow.com/a/9550231/1254514
"Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation."
So I had to do the following:
Add in your Android manifest to the activity you like:
android:configChanges="keyboardHidden|orientation|screenSize"
Then override the function in your activity:
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
Maybe if you try something like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(getSharedPreferences(RPSActivity.PREFS_NAME, 0).getBoolean(RPSActivity.FULLSCREEN, true)) this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.paypal);
initUI();
if(savedInstanceState != null)
{
/** Restoring the web Ui state. */
webView.restoreState(savedInstanceState);
}
}
#Override
public void onSaveInstanceState(Bundle outState)
{
/** Saving the webview state. */
webView.saveState(outState);
}
This is untested but it seems like you are not saving the state of the webview. I am using this code in a Fragment and it seems to save the state of the webview.
