I’ve been making android apps for like 4-5 days now. So i’m wondering if you know how I can make a web app? I have been looking through many tutorials, but none shows directly how I can make an app that displays the content from a website, and that I can decide what I want and don’t want to display. So I really just want to customize a website into an app and make my own layout. I know how the WebView and WebContent works and all that stuff, but I don’t know how I can do what I described here.
So what do I need to learn and know to make an app like that?
You can do it by fill your xml layout with EdidText for the url and Buttons for Go, back, forward and so on, finally you need webview in this xml layout.
for the java code you can check the below sample.
public class SimpleBrowser extends Activity implements OnClickListener {
WebView myBrowser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simplebrowser);
//here the code for initialize and set yourwebView Settings.
myBrowser= (WebView) findViewById(R.id.wvBrowser);
//the below line to enable javascript if you want that
myBrowser.getSettings().setJavaScriptEnabled(true);
//here another settings could be enabled for you your webview
myBrowser.getSettings().setLoadWithOverviewMode(true);
myBrowser.getSettings().setUseWideViewPort(true);
try {
//here the default web page
ourBrow.loadUrl("http://www.google.com");
}catch (Exception e){
e.printStackTrace();
}
}
}
and for sure you need to implements your buttons using onClicklistener to be suitable for your idea.

I'm very new to developing android apps. I've edited this app I found, which was open source and have got it working to a good extent. There's some code that isn't being used at all (Like the preferences menu) but I haven't removed that as I simply don't want to mess it up. Anyway, when I view the website it's zoomed in.. I've researched the problem and found a few ways to fix it, but none have worked. The app files can be downloaded at this link: http://www.megafileupload.com/en/file/504860/App-zip.html
Thanks for any help!
Now, here's where the answer comes in.
You get the settings for your webview before you instantiate it. You need something like:
void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard); // do this first
WebView webView = (WebView) findViewById(R.id.yourwebviewid); // either this or
either the above to tie the Java object to an xml object
or create a view and add it to some parent
View parent = (View)findViewById(R.id.yourparent_layout_for_webview); // this
WebView webView = new WebView();
parent.add(webView);
webView.getSettings().setBuiltInZoomControls(true);
lets say I have an application for my University web site. Where user can navigate by pressing on screen button( Actually, what I did, I categorized everything in my main layout,where each button represents each fields, if any one presses myaccountStatus, then he will be directed to that specific link) However, my web site needs user name and password every time. Where I don't want my user to bother about this at all. So my question is, is there any way I can enable auto-log in?
My application has basic core web feature implemented(WebView, zoom, java-script enabled, some back, forward, stop, reload, favorite, save for offline reading) and everything is working fine, please help with the auto-log in problem.
So far I know, I can do this by saving cookies. But I have no Idea, how they look, what are they and how to handle those thing. So, please give me a step by step tutorial for this problem. Thanks in advance.
If your are using a web-view based approach (maybe something like cordova?) you could just use the local storage or the web sql standard for html5 apps: Tutorial for Web-Sql.
If you want to store cookies you have to enable them. I'm doing this in my Phonegap/Cordova application with this small Lines of code:
#Override
public void onCreate(Bundle savedInstanceState) {
// ... do whatever you want...
// this lines allow to set cookies
try {
CookieManager.setAcceptFileSchemeCookies(true);
} catch (Throwable e) {
}
// and the default stuff for phonegap/cordova to show a splashscreen and load the application
super.onCreate(savedInstanceState);
super.setIntegerProperty("splashscreen", R.drawable.splash);
// load the index url from config adding locale support.
super.loadUrl(Config.getStartUrl() + "?locale="
+ Locale.getDefault().getLanguage(), 4000);
}
I hope this helps.
Peace be on all of you!
I have to develop a questionnaire like small android app. There will be 10 questions with only 2 types of answers, i.e. either "Yes" or "No". When the user will answer all of the 10 questions, a report will be shown to user according to his answers.
Kindly tell me, how should I proceed? Do I need to use database (sqlite) or can work without it? and how should I start to develop this app?
I am new to Android.
Thank-you!
If you are new to Android, than use a web approach: Show a html page 1-10 in a webView and link it each other and finally the 10th is linked to an url, where you will do a http POST / GET with your collected 10 params. Exactly as how would you do in a "standard' web development. Also you can use several app to wrapp into Android app: Appcelerator, Phonegap and so on.
Here is a class which is a screen: (Android Activity)
public class Help extends Activity{
private WebView webViewHelp;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);
webViewHelp = (WebView) findViewById(R.id.webViewHelp);
webViewHelp.loadUrl("file:///android_asset/ui/help.html");
}
}
you need the help.xml build and placed into /res/layout/ folder.
Also write the help.html and place it into: /assets/ui folder and not android_asset and at is not file:///assets/ui/help.html!
in this case you have the starting point set up, than go and load with html links the next next next ... until is done, than pust url.
Somewhat easyer if you are doing in android ui development, and not web-like, but that need a bit more experience
I've been trying to connect to twitter through android for a while.
I'm currently using this api: http://kenai.com/projects/twitterapime/forums/forum/topics/13327-Twitter-API-ME-1-8-Now-with-OAuth-support
I used their exemple with my keys and everything connects without problem. So no problem with configuration.
But in my project which has exactly the same code I can't make it work.
I believe its related with the creation of a new Intent (also this is where the eclipse is point the error)
Im trying to use a custom layout but I don't know what do I need to change to make this specific Twitter layout to work. On main activity I have a button with this:
public void onClick(View v)
{
startActivity(new Intent(this,Twitter.class));
}
on twitter class
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//this.webView = (WebView) findViewById(R.id.webView1);
WebView myWebView = new WebView(this);
setContentView(myWebView);
authenticate();
}
private void authenticate()
{
WebViewOAuthDialogWrapper page = new WebViewOAuthDialogWrapper(webView);
page.setConsumerKey(CONSUMER_KEY);
page.setConsumerSecret(CONSUMER_SECRET);
page.setCallbackUrl(CALLBACK_URL);
page.setOAuthListener(this);
page.login();
}
what requirements/adjustments are needed to make/change to the Twitter activity?
I believe I need to change something in the intent-filter but I don't even understand the work of intents. I've been only making easy layouts.
Note that I also gave internet permissions already.
Looks like i was making 2 mistakes.
First i was trying to use "webView" variable in WebViewOAuthDialogWrapper instead
"myWebView" so it wasn't initialized...
Second looks like i forgot to put the order of which the external libraries were loaded....
So be sure to put external libraries on top in eclipse project.
Lost about 2 days with these problems... oh well
I already asked this question, but got answers that don't work and it counted as "Answered". Maybe someone knows how to design button in Eclipse for an Android app, so it takes you to a website ?Let's say this website.Thanks a lot.
Say u wanna go to google.com
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onOpenWebBrowser(View v)
{
Intent webPageIntent = new Intent(Intent.ACTION_VIEW);
webPageIntent.setData(Uri.parse("https://www.google.co.in/"));
try {
startActivity(webPageIntent);
} catch (ActivityNotFoundException ex) {
}
}
}
Make sure u add uses internet permission to the manifest!
you can refer the following to get an idea ,
see this vogella from there, you can get idea how to create android app which has a Button
http://www.vogella.de/articles/Android/article.html
and then create WebView in xml and map it in java, as
http://developer.android.com/resources/tutorials/views/hello-webview.html
and For mor info refer android people.com
http://www.androidpeople.com/
http://developer.android.com/resources/samples/index.html
and also read my blog to know about android basics
http://sankarganesh-info-exchange.blogspot.com/p/corridor-your-foremost-footstep-in.html
You would need to set up an OnClickListener and tie it to your button. In the Listener's onClick method, you would load the specified URL into the WebView, which, based on your comments, it sounds like you've got that part figured out.
