I have four groups in a listview each with four url's I want to load in a webView. When the user select a url to goto I set a value like so;
if (position == 0) webb = webb +2;
{
Intent intent = new Intent(this, official.class);
startActivity(intent);
}
I then carryout the intent to move to the webView class where I have given each URL a value like so;
if (webb == 2) mWebView.loadUrl("http://yahoo.com");
if (webb == 3) mWebView.loadUrl("http://www.bbc.co.uk");
But the screen stays blank, if I state the value inside the official.class it works. How can I get this value to pass to another class based on the selection the user makes from the listview.
I have been trying to get "getExtra" to work but without success, I have a listview with 4 choices which launch a webpage within a webView class, when the user selects the option lets say option 3 I want to pass the value of 3 to the webView class so that it will load the correct webpage, at the moment I get no errors, but the app force closes when I select the option, could this be due to having to announce this in the manifest? can somebody help with where I am going wrong. This is my intent
public void onListItemClick(ListView l, View v, int position, long id) {
if (position == 0) {
Intent intent = new Intent(this, official.class);
intent.putExtra("weburl", 3);
startActivity(intent);}
This is the official class:
public class official extends Activity {
int number = getIntent().getIntExtra("weburl", 0);
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
} return super.onKeyDown(keyCode, event);
} WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.browser1);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
if (number == 2) mWebView.loadUrl("http://bcafc.livewwware.co.uk");
if (number == 3) mWebView.loadUrl("http://www.bbc.co.uk");
mWebView.setWebViewClient(new HelloWebViewClient());
I had write two classes IntentA and IntentB in my application (Both are in same package and both extends Activity class). In IntentA class I had created one button on pressing that button controll is trsnfer to IntentB class. IntentB class also contain Button on pressing that control is transfer to IntentA class.
This work fines. Now I want to set value in IntentA class using putExtra method and access that value in IntentB class How should I do that? I had put value in class IntentA like
Intent i1 = new Intent(this,IntentB.class);
i1.putExtra("Intent Name", "IntentA");
startActivity(i1);
Now I don't know How to access "Intent Name" value in IntentB class.

My current problem is that I don't receive an intent. I have a BroadcastReceiver and defined in the AndroidManifest.xml file that it also should receive intents with these actions.
View 2 Replies View RelatedI've got two activities, one of them is called MyActivity. I want both of them to be able to use a function located in a class othat we may call MyClass. In MyClass, I try to use an intent to launch the activity AnotherActivity. Since the constructor takes a context as parameter, I simply tried to store a context from the activity in the constructor, and then use it when I try to create my intent.However, even thought none of the arguments are null (checked that with a simple if-statement), intent seems to be null and a NullPointerException is thrown. Why does it not work, and what can I do to solve the problem?
I'm quite new to Android and Java development, so please explain it as basic as you can.

how can i tell the intent to use the class i wrote to give back?
I am calling intents alot in my program and I thought that I could write a public class that would have all of my intents so I can just call something like intents.testIntent(params) and then have it fire off the intent.

View 1 Replies View RelatedI'm posting this to share the lessons I learned while working with IntentService. IntentService has a single constructor that takes a string argument "name". The documentation has no description of what name is used for. In looking at the sources, I found that its only use is in naming the worker thread for the IntentService. This thread is named IntentService [name].
I initially implemented the constructor of the derived class to also take a String argument and passed it along to the derived class. This is wrong. This will cause the startService() call to generated a java.lang.InstantiationException in the application containing the service i.e. you don't get the exception in the application calling startService(). A clue to the actual problem is a little further up in the logs:"newInstance failed: no <init>()"
The derived class must have a Default constructor and that constructor must call super() passing a string for the name component of the worker thread name.
public class MyIntentService extends IntentService {
public MyIntentService() { super("MyIntentService");
} @Override
protected void onHandleIntent(Intent intent) {
// Handle events on worker thread here }
I had come across a code snippet which calls for an activity without referring to any context. Before, i was considering that context is used to tell about the calling component. But as i came see that another component can be called without any reference to context, it makes me wonder what purpose it might be serving. please put some light on it.
Here is the code which calls for an activity without referring to 'context'

I want to specifically run the default Android browser for a given URL. I'm using this code: I also tried adding <uses-library android:name="com.google.android.browser" /> to the manifest. Am I missing something here? PS: I'm not interested in using startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"))) as it will list all the choices for the browsing Intent.
View 3 Replies View RelatedIs it possible to receive an explicit intent with the component option set? Example: Starting activity: Intent { action=android.intent.action.VIEW data=http://example.org flags=0x10000000 comp={com.android.browser/com.android.browser.BrowserActivity}}
The reason why i want to this this is because i want receive this intent above, launch another browser than the default one, and drop the intent before it starts the default browser. In another words, i want to make another browser the default one.

Suppose I want to include data right in an intent, e.g. pass a number or string in the intent data field.What should the uri look like? Something like "data:3.14159"?Or just don't include the scheme at all, "3.14159"? In fact, is there a list of standard schemes anywhere?
View 4 Replies View RelatedI was just wondering if it is possible to give the intent a set of data, instead of just one. A particular scenario where this could be applicable would be a music application.You select a list of songs, and pass all these data (file path) to the Music Player's application.Another scenario: You need to plot more than one address on the Google Maps. You launch the application with a set of data for the intent.
View 5 Replies View RelatedI'd like to send an sms message. If the text is too long, I split it into multiple messages. I'm trying to put some extra info into the "sent" intent to know which part has been sent, and when all the parts are complete: The message is sent, and I catch the intent when each part is sent - but the intent always has the same data in it. For example, "partIndex" is always zero, even though for the second message, it should be one. Seems like the same intent just keeps getting thrown to my broadcast receiver. What's the right way to do this?

I would like to create some home screen app widgets that are entry points into an application. I can put a button in the app widget that uses setOnClickPendingIntent to start the activity. The problem occurs when I want to have two of these app widgets that are entry points to different parts of the activity. I need to be able to pass data into the activity that will distinguish these. Since both app widgets use a Pending Intent that starts the same activity, the two Pending Intents are shared and I can't reliably set extras for the corresponding intents.
