last tempt at asking for help

Ok all i have tried for weeks now to get a simple webview app sorted. i have managed to get this up on the market but it needs a few more features like menu for refresh back forward etc.
It seems nobody really wants to helps so how much will it cost me for you to help with it?

explain a little more, you after someone to code it for you or design the ui ?

Well basically I got a basic webview made from tutorials, but that is about as far as my skills go. I need a few more features like options menu, stop the back button exiting app and go back a page instead and also if possible but not essential change loading bar for loading circle which spins in middle if screen while loading. I have tried to ask for help with what code I need and where to put it but no luck. I pretty much need it coded or at least to be told what code and exactly where in my code I need to fit it in.

Where have you tried asking? Tackle one issue at a time, and post some example code.
StackOverflow is a great site for programming questions and you should get some good answers there.
But before posting make sure you search first.
The back button shouldnt exit the app if there is a activity that was displayed before it.

I found this tutorial after a quick google search - http://kahdev.wordpress.com/2008/11/25/building-a-menu-for-your-android-v10-r1-app/
It seems quite simple to follow. Let me know if you have any issues and I try give you an example for your code tonight.

Ok I have edited your code to add a menu, and also to set the back button of the phone to go back to the previous page in the webview, instead of previous activity.
I found the code for this here
I have commented bits of the code so hopefully its understandable.
If you have any questions or it doesn't work let me know.
Don't just take what I have done and use it (although you can). Go through it and make sure you understand what I have done. That's the only way you will learn app development.
Code:
package com.windowcleaningforums;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class windowcleaningforums extends Activity {
final Activity activity = this;
//DECLARE webview variable outside of onCreate function so we can access it in other functions (menu)
public WebView webView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.WebView);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setTitle(" Loading...");
activity.setProgress(progress * 100);
if (progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// Handle the error
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://www.windowcleaningforums.co.uk");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
//Add menu items, second value is the id, use this in the onOptionsItemSelected
menu.add(0,1, 0, "Back");
menu.add(0, 2, 0, "Forward");
return true;
}
@Override
public boolean onOptionsItemSelected (MenuItem item){
switch (item.getItemId()){
//If the ID equals 1 , go back
case 1:
webView.goBack();
return true;
//If the ID equals 2 , go forward
case 2 :
webView.goForward();
return true;
}
return false;
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}

I have seen these tutorials but my problem is I don't know how to fit it into my webview where should I add this in my code
Sent from my Desire HD using XDA App

Have a look at the code I posted.
What we are basically doing is adding new functions (or methods) inside our activity class. When I first started app development I also got confused as to where to add things.
These new methods override methods built into the activity, so we don't want to put them inside our onCreate method (where everything goes for setting up the activity, and where all your current code resides).
So we put them at any position after the closing brace of our onCreate. I've put them at the end.
I also moved the declaration of the webView variable to outside the onCreate method, so we can access it in the other functions we added.

Thank you so much I will look at this properly when I next get chance on my pc. thanks again for the help and taking the time to explain.

Thank you have have looked over the code and even added another button!
I have also added icons for each menu item after looking over some other code but not sure if i have done it correctly. they dont show untill the menu item has been clicked once. how can i get them to show right away? i put the images in res/drawable and called then in the code below, is this the correct way to do it?

As SilentMobius' comments pointout, you need to set your icons in the onCreateOptionsMenu, not the onOptionsItemSelected.
That's why they are only showing when you select the button.

Ah great thanks i figured it, didn't want to be given correct code just you giving the correct info to sort my self is good i know these are most likely simple things but nobody learns unless they ask questions thanks again.
Check my apps out in the market Luvdroid and window cleaning forums

Would you mind sharing your back, forward and refresh icons with me? I'm looking for something very clean and standardized for use on 12 webview apps for the some of the local municipalities.

ProgressBar not working

Hey, I was working on progress Bars. But I am having a little trouble. On the following code, The bar seems to work perfectly, but just when its done loading. The app crashes. Please help me out. Thanks in advance
Code:
package com.example.progresses;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.ProgressBar;
public class MainActivity extends Activity {
ProgressBar b;
int progressStatus = 0;
static int progress = 0;
Thread t;
Handler hand = new Handler();
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b = (ProgressBar) findViewById(R.id.progressBar1);
b.setMax(200);
new Thread(new Runnable() {
public void run() {
while (progressStatus <= 200) {
progressStatus = doWork();
hand.post(new Runnable() {
public void run() {
b.setProgress(progressStatus);
}
});
}
b.setVisibility(View.GONE);
}
}).start();
}
private int doWork() {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ++progress;
}
}
LOGCAT

You have to do this via the handler, too:
Code:
b.setVisibility(View.GONE);
Every action regarding the UI from another thread has to be done via an handler.

url loading handling in webview

Basic question, what did i do? Hahaha. What did i do to make url load inside webview?
At first i overridden shouldOverrideUrlLoading to control where the link loads, then i one time i removed it but url still loads inside webview. And now i need to once again override url loading because i need a link to be opened on the default browser, but i don't know how.

That's a messed Op . If your code is short. use code tags. If its big, use paste bin to make it easy for people to read the question and answer it!

He just said that you should wrap your code into
Code:
tags or upload it elsewhere because nobody will read it as it is right now. Can you read that code from your browser? If you put it into [CODE] tags, it will look like this: [URL]http://forum.xda-developers.com/showthread.php?p=44976604#post44976604[/URL]
Then people will be able to read it. ;)

tags or upload it elsewhere because nobody will read it as it is right now. Can you read that code from your browser? If you put it into [CODE] tags, it will look like this: [URL]http://forum.xda-developers.com/showthread.php?p=44976604#post44976604[/URL]
Then people will be able to read it. ;)[/QUOTE]
Oh. sorry. Haha. There, thanks. :)

[Volley] Main UI extremely slow

In my app i just have a splash screen and a main activity. In the main thread i have three EditText boxes and a spinner with a string array. On clicking the Button, input from three EditText and spinner selection is posted to my mysql database. For the button click network operation, i used Volley since its east and i dont have to use AsyncTask which am not familiar with.
Apart from this, on entering the main UI .. app first check for network connectivity using ConnectivityManager class. After onClick app checks for empty/invalid imputs using TextUtils.
Now the problem is that when i run my app, its very slow and taking upto 65mb of RAM. IS something wrong with my code. Should i run something else as AsynTask ? Can someone check my code and refine it .. thank you

Well it's hard to say what exactly is wrong with it. Maybe text is to long. You can try to measure each operation performance with System.nanoseconds(easiest) and localize the problem first. It would be easier to say what to do with it.

Yes you should try to figure out what part is causing the problem. Try to cut the code down to essentials and measure the execution time. Maybe you will be able to tell what part exactly is not working as wanted.
