If I have created a deep link using the branch.io that opens a specific screen in my app. If this link is also available in my app and a user clicks on it, will it open my screen? or it will do nothing as the link I am trying to open from the app is pointing to the same app?
When you click on a Branch link within a webView in your App, you will have to handle the routing to the specific Activity, after reading the Branch link parameters.
Here is a sample Activity which contains a webView and and shows a couple of Branch links. When you click on a link in the webView it reopens the webview and displays the link parameters in a Toast message if a Branch link is clicked
public class MainActivity extends AppCompatActivity {
private WebView webView_;
private Button button_;
private String TAG = "WebViewController";
private Context context_;
private static final String URL_TO_LOAD = "https://evangelosg.github.io/index.html";
private static final String BRANCH_LINK_TO_LOAD = "https://ere6.app.link/b6sS0gsCfG";
#Override
protected void onNewIntent(Intent intent) {
Log.d("WebView", "onNewIntent");
setIntent(intent);
}
#Override
protected void onResume() {
super.onResume();
Branch branch = Branch.getInstance();
branch.initSession(new Branch.BranchReferralInitListener() {
#Override
public void onInitFinished(JSONObject referringParams, BranchError error) {
if (error == null) {
Log.d(TAG, referringParams.toString());
Toast.makeText(context_, referringParams.toString(), Toast.LENGTH_LONG).show();
if (referringParams.has(BundleExtraKeys.CLICKED_BRANCH_LINK)) {
try {
boolean clickedBranchLink = referringParams.getBoolean(BundleExtraKeys.CLICKED_BRANCH_LINK);
if (clickedBranchLink) {
//do stuff!
}
} catch (JSONException e) {
Log.d("BranchTrends", e.getMessage());
}
}
} else {
Log.i("MyApp", error.getMessage());
}
}
}, this.getIntent().getData(), this);
}
#Override
protected void onStart() {
super.onStart();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context_ = this;
setContentView(R.layout.activity_main);
webView_ = (WebView) findViewById(R.id.webView);
webView_.setWebViewClient(new BranchWebViewController("app.link", MainActivity.class));
webView_.loadUrl(URL_TO_LOAD);
button_ = (Button) findViewById(R.id.button);
button_.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.intent.putExtra("branch", BRANCH_LINK_TO_LOAD);
customTabsIntent.intent.putExtra("branch_force_new_session", true);
finish();
customTabsIntent.launchUrl(MainActivity.this, Uri.parse(BRANCH_LINK_TO_LOAD));
}
});
}
public class BranchWebViewController extends WebViewClient {
private String myDomain_;
private Class activityToLaunch_;
BranchWebViewController(#NonNull String myDomain, Class activityToLaunch) {
myDomain_ = myDomain;
activityToLaunch_ = activityToLaunch;
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
String url = request.getUrl().toString();
if (url.contains(myDomain_)) {
Intent i = new Intent(view.getContext(), activityToLaunch_);
i.putExtra("branch", url);
i.putExtra("branch_force_new_session", true);
finish();
startActivity(i);
} else {
view.loadUrl(url);
}
return true;
}
}
}
Once you read the link parameters you can route to the appropriate Activity based on the link parameters.
I am building a download manager
Here I have shown a test code which tries to update fileNameColumn of a row of tableView but it is not being updated after I connect to url
To be specific, here fileName remains hello1 and it doesnt get updated to hello2. Yhy's that so?
Main.java :
public static TableView<DownloadEntry> downloadsTable;
public TableColumn<DownloadEntry, String> fileNameColumn;
public void initialize(URL location, ResourceBundle resources) {
downloadsTable = new TableView<DownloadEntry>();
fileNameColumn = new TableColumn<>("File Name");
fileNameColumn.setCellValueFactory(new PropertyValueFactory<>("fileName"));
executor = Executors.newFixedThreadPool(4);
}
public void addDownloadButtonClicked() {
try{
String urlText = urlTextBox.getText();
DownloadEntry task = new DownloadEntry(new URL(urlText));
downloadsTable.getItems().add(task);
executor.execute(task);
}
catch(Exception e) {
System.out.println("addDownloadButtonClicked: " + e);
}
}
DownloadEntry.java:
public class DownloadEntry extends Task<Void> {
public SimpleStringProperty fileName;
public URL url;
//Constructor
public DownloadEntry(URL ur) throws Exception{
fileName = new SimpleStringProperty("hello");
url = ur;
}
#Override
protected Void call() {
try {
HttpURLConnection connect=(HttpURLConnection)url.openConnection();
fileName.set("hello1");
connect.connect();
fileName.set("hello2");
}
catch(Exception E) {
this.updateMessage("Error");
E.printStackTrace();
}
return null;
}
public String getFileName() {
return fileName.get();
}
public void setFileName(String fileName) {
this.fileName = new SimpleStringProperty(fileName);
}
}
Please tell if you need more details..
Your model is incorrectly implemented. The setFileName method should be
public void setFileName(String fileName) {
this.fileName.set(fileName);
}
(The problem with your implementation is that the table is still observing the old property, not the new one you create.)
You will also need to provide a "property accessor" method:
public StringProperty fileNameProperty() {
return fileName ;
}
which will allow the table to properly bind to the property (so that it "knows" when its value changes).
I'm new to android development and I have been struggling to parse more than one tag at a time and display it in a ListView.
I'm using SAX parser, here is my RssParseHandler code.
public class RssParseHandler extends DefaultHandler {
private List<RssItem> rssItems;
private RssItem currentMessage;
//private StringBuilder builder;
private boolean parseLink;
private boolean parseTitle;
private boolean parseDate;
private boolean parseDes;
public RssParseHandler() {
rssItems = new ArrayList();
}
public List<RssItem> getItems() {
return this.rssItems;
}
#Override
public void startElement(String uri, String localName, String name,
Attributes attributes) throws SAXException {
super.startElement(uri, localName, name, attributes);
if (localName.equalsIgnoreCase("item")) {
this.currentMessage = new RssItem();
} else if (localName.equalsIgnoreCase("title")) {
//currentMessage.setTitle(builder.toString());
parseTitle = true;
} else if (localName.equalsIgnoreCase("link")) {
//currentMessage.setLink(builder.toString());
parseLink = true;
} else if (localName.equalsIgnoreCase("description")) {
//currentMessage.setDescription(builder.toString());
parseDes = true;
} else if (localName.equalsIgnoreCase("pubDate")) {
//currentMessage.setDate(builder.toString());
parseDate = true;
}
//parsing enclosure tag
else if ("enclosure".equals(localName)) {
// Get tags attributes number
int attrsLength = attributes.getLength();
for (int i = 0; i < attrsLength; i++) {
String attrName = attributes.getQName(i); // attribute name
if ("url".equals(attrName)) // This tag has only one attribute but it is better to check it name is correct
currentMessage.getLink();
}
}
}
#Override
public void endElement(String uri, String localName, String name)
throws SAXException {
super.endElement(uri, localName, name);
if (this.currentMessage != null) {
if (localName.equalsIgnoreCase("item")) {
rssItems.add(currentMessage);
//currentMessage = null;
} else if (localName.equalsIgnoreCase("link")) {
//currentMessage.setLink(builder.toString());
//parseLink = false;
} else if (localName.equalsIgnoreCase("description")) {
//currentMessage.setDescription(builder.toString());
//parseDes = false;
} else if (localName.equalsIgnoreCase("pubDate")){
//currentMessage.setDate(builder.toString());
parseDate = false;
} else if (localName.equalsIgnoreCase("title")) {
//currentMessage.setTitle(builder.toString());
parseTitle = false;
}
//builder.setLength(0);
}
}
#Override
public void characters(char[] ch, int start, int length)
throws SAXException {
super.characters(ch, start, length);
//builder.append(ch, start, length);
if (parseTitle) {
if (currentMessage != null)
currentMessage.setTitle(new String(ch, start, length));
} else if (parseLink) {
if (currentMessage != null) {
currentMessage.setLink(new String(ch, start, length));
//parseLink = false;
}
} else if (parseDes) {
if (currentMessage != null)
currentMessage.setDescription(new String(ch, start, length));
//parseLink = false;
} else if (parseDate) {
if (currentMessage != null) {
currentMessage.setDate(new String(ch, start, length));
//currentMessage.setDate(new String(ch, start, length));
//parseDesc = false;
}
}
}
}
Here is the code for the Listview:
public class ReaderAppActivity extends Fragment {
private ReaderAppActivity local;
private ListView mList;
/**

#Override

// Creating view corresponding to the fragment
View v = inflater.inflate(R.layout.fragment_rss, container, false);
// Set reference to this activity
//local = this;
GetRSSDataTask task = new GetRSSDataTask();
// Start download RSS task
task.execute("http://thechurchofwhatshappeningnow.libsyn.com/rss");
//task.execute(url);

Log.d("ITCRssReader", Thread.currentThread().getName());
//mList = (ListView) findViewById(R.id.rssListMainView);
return v;
}
private class GetRSSDataTask extends AsyncTask<String, Void, List<RssItem> > {
#Override
protected List<RssItem> doInBackground(String... urls) {
// Debug the task thread name
Log.d("ITCRssReader", Thread.currentThread().getName());
try {
// Create RSS reader
RssReader rssReader = new RssReader(urls[0]);
// Parse RSS, get items
return rssReader.getItems();
} catch (Exception e) {
Log.e("ITCRssReader", e.getMessage());
}
return null;
}
#Override

mList.setOnItemClickListener(new ListListener(result, getActivity()));
}
}
}
What am I doing wrong? I can't figure it out. I would like to parse, the link, description, pubDate, and pass them into the ListView. Ideally I would only display the title and episode number in the listview, and pass the other tags into String, so I can display them when I click an item in the listView.
I've created another class called SingleMenuItem to be called when I click an item in the ListView, it's just filler code right now, it does not display anything because the items aren't parsed.
Any help would be appreciated. Here is a RSS link to the feed:
public class SingleMenuItem extends Activity {
// XML node keys
static final String KEY_NAME = "name";
static final String KEY_DATE = "pubdate";
static final String KEY_DESC = "description";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.single_list_item);
// getting intent data
Intent in = getIntent();
// Get XML values from previous intent
String name = in.getStringExtra(KEY_NAME);
String date = in.getStringExtra(KEY_DATE);
String description = in.getStringExtra(KEY_DESC);
// Displaying all values on the screen
TextView lblName = (TextView) findViewById(R.id.name_label);
TextView lblDate = (TextView) findViewById(R.id.date_label);
TextView lblDesc = (TextView) findViewById(R.id.description_label);
lblName.setText(name);
lblDate.setText(date);
lblDesc.setText(description);
}
}
Here is the code for my ReaderAppActivty that puts the results of the parsing into the ListView:
public class ReaderAppActivity extends Fragment {
private ReaderAppActivity local;
private ListView mList;
/**
* This method creates main application view
*/
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//super.onCreate(savedInstanceState);
// Set view
//setContentView(R.layout.fragment_rss);
local = this;
//int position = getArguments().getInt("position");
// String url = getArguments().getString("url");
// List of rivers
String[] menus = getResources().getStringArray(R.array.menus);
// Creating view corresponding to the fragment
View v = inflater.inflate(R.layout.fragment_rss, container, false);
// Set reference to this activity
//local = this;
GetRSSDataTask task = new GetRSSDataTask();
// Start download RSS task
task.execute("http://thechurchofwhatshappeningnow.libsyn.com/rss");
//task.execute(url);
// Debug the thread name
Log.d("ITCRssReader", Thread.currentThread().getName());
//mList = (ListView) findViewById(R.id.rssListMainView);
return v;
}
private class GetRSSDataTask extends AsyncTask<String, Void, List<RssItem> > {
#Override
protected List<RssItem> doInBackground(String... urls) {
// Debug the task thread name
Log.d("ITCRssReader", Thread.currentThread().getName());
try {
// Create RSS reader
RssReader rssReader = new RssReader(urls[0]);
// Parse RSS, get items
return rssReader.getItems();
} catch (Exception e) {
Log.e("ITCRssReader", e.getMessage());
}
return null;
}
#Override
protected void onPostExecute(List<RssItem> result) {
// Get a ListView from main view
ListView mList = (ListView) getView().findViewById(R.id.rssListMainView);
// Create a list adapter
ArrayAdapter<RssItem> adapter = new ArrayAdapter<RssItem>(getActivity(),R.layout.rss_text, result);
//ArrayAdapter<RssItem> adapter = new ArrayAdapter<RssItem>(getActivity(),R.layout.fragment_rss, result);
// Set list adapter for the ListView
mList.setAdapter(adapter);
// Set list view item click listener
mList.setOnItemClickListener(new ListListener(result, getActivity()));
}
}
}
Based on the amount of commented-out code in your RssParseHandler, you've clearly been struggling with this for a bit, and some early attempts were closer to right than what you've got now.
The issue with your current code appears to be that you're not consistently resetting the booleans that drive which part of the item you're setting. Debugging through it, I saw it setting a date into the link field at some point.
But you're actually doing some of that setting in the wrong method, as the characters method doesn't necessarily give you the full contents of the tag. You need to use a Stringbuilder, and I can see from commented-out code that you tried that at some point.
If you collect the text in a stringbuilder and do all the setting in the endElement method, you don't really need the booleans at all, as the endElement method has knowledge of which tag you're ending.
Here's a working version that's perhaps not too far from something you had at some point but which gets rid of all those flag fields.
public class RssParseHandler extends DefaultHandler {
private List<RssItem> rssItems;
private RssItem currentMessage;
private StringBuilder builder;
public RssParseHandler() {
rssItems = new ArrayList<>();
builder = new StringBuilder();
}
public List<RssItem> getItems() {
return this.rssItems;
}
#Override
public void startElement(String uri, String localName, String name,
Attributes attributes) throws SAXException {
super.startElement(uri, localName, name, attributes);
builder.setLength(0);
if (localName.equalsIgnoreCase("item")) {
this.currentMessage = new RssItem();
}
}
#Override
public void endElement(String uri, String localName, String name)
throws SAXException {
super.endElement(uri, localName, name);
if (this.currentMessage != null) {
if (localName.equalsIgnoreCase("item")) {
rssItems.add(currentMessage);
currentMessage = null;
} else if (localName.equalsIgnoreCase("link")) {
currentMessage.setLink(builder.toString());
} else if (localName.equalsIgnoreCase("description")) {
currentMessage.setDescription(builder.toString());
} else if (localName.equalsIgnoreCase("pubDate")){
currentMessage.setDate(builder.toString());
} else if (localName.equalsIgnoreCase("title")) {
currentMessage.setTitle(builder.toString());
}
}
}
#Override
public void characters(char[] ch, int start, int length)
throws SAXException {
super.characters(ch, start, length);
builder.append(ch, start, length);
}
}
I have a button on a ListGrid, for the button I have:
.addClickHandler(new ClickHandler()
{
#Override
public void onClick(final ClickEvent event)
{
SC.confirm("Are you sure?", new BooleanCallback()
{
#Override
public void execute(Boolean value)
{
if (value == null || Boolean.FALSE.equals(value))
{
event.cancel();
return;
}
// How do I call RS : //localhost:8080/service/task1
}
});
}
How do I send a request to that rest service URL? the base URL is the same, they are on the same grid. The type is a #GET
You can create RestDataSource in SmartGWT. Something like this
final RestDataSource dataSource = new RestDataSource() {
#Override
protected Object transformRequest(DSRequest request) {
request.setHttpMethod("GET"); // To set the HTTP method as "GET"
return super.transformRequest(request);
}
};
dataSource.setDataFormat(DSDataFormat.JSON); //set format
dataSource.setFields(); // set fields
dataSource.setDataURL("localhost:8080/service/task1");
On Click of the button call this:
dataSource.fetchData();
Here is My Code.
I just want to get the page content from the Webview after load the URL .
On Android, I have a WebView that is displaying a page.
How do I get the page source without requesting the page again?
It seems WebView should have some kind of WebResourceResponse () method in Android 3.0 but don't know how to use it.
public class WebActivity extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webView);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("https://xyz.com");
mWebView.setWebViewClient(new HelloWebViewClient());
}
private class HelloWebViewClient extends WebViewClient {
public WebResourceResponse shouldInterceptRequest (WebView view, String url)
{
return null;
}
#Override
public void onPageFinished(WebView view, String url)
{
/* This call inject JavaScript into the page which just finished loading. */
mWebView.loadUrl("javascript:window.HTMLOUT.processHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}}
I know this is old, but for future visitors, the following should work.
First, you need to define an interface such as:
final class LoadingInterface {
#JavascriptInterface
public void outputHTML(final String html){
//do what ever you want with html
}
}
Then on your WebView call
webView.addJavascriptInterface(new LoadingInterface(), "INTERFACE");
In onPageFinished put:
String js = "javascript:"
+"var html = document.getElementsByTagName('html')[0].innerHTML;"
+"window.INTERFACE.outputSchedule(html);";
webView.loadUrl(js);
If you only need part of a page, you can replace getElementsByTagName('html')[0] with something like getElementById('partOfPage')
