How to get url from browser using accessibility service

How to get url from browser using accessibility service - android

I have enabled accessibility-service permission and now i want to get url from address bar.
I have tried below thing :
accessibility_service_config.xml
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeAllMask"
android:accessibilityFeedbackType="feedbackAllMask"
android:accessibilityFlags="flagDefault"
android:canRetrieveWindowContent="true"
android:description="#string/accessibility_service_description"
android:notificationTimeout="0"
android:canRequestFilterKeyEvents="true"
android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity" />
AccessService.java
public class AccessService extends AccessibilityService {
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
AccessibilityNodeInfo source = event.getSource();
if (source == null)
return;
final String packageName = String.valueOf(source.getPackageName());
String BROWSER_LIST = "com.android.chrome";
List<String> browserList
= Arrays.asList(BROWSER_LIST.split(",\\s*"));
if (event.getEventType()
== AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED) {
if (!browserList.contains(packageName)) {
return;
}
}
if (browserList.contains(packageName)) {
try {
if (AccessibilityEvent
.eventTypeToString(event.getEventType())
.contains("WINDOW")) {
AccessibilityNodeInfo nodeInfo = event.getSource();
getUrlsFromViews(nodeInfo);
}
} catch (StackOverflowError ex) {
ex.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
public void getUrlsFromViews(AccessibilityNodeInfo info) {
try {
if (info == null)
return;
if (info.getText() != null && info.getText().length() > 0) {
String capturedText = info.getText().toString();
Bundle arguments = new Bundle();
if (capturedText.contains("https://")
|| capturedText.contains("http://")) {
if (capturedText.contains("facebook.com")) {
// open new tab
}
}
}
for (int i = 0; i < info.getChildCount(); i++) {
AccessibilityNodeInfo child = info.getChild(i);
getUrlsFromViews(child);
if (child != null) {
child.recycle();
}
}
} catch (StackOverflowError ex) {
ex.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
}
}
#Override
public void onInterrupt() {
}
#Override
protected void onServiceConnected() {
super.onServiceConnected();
}
}
The problem here i am facing here is when i type facebook.com in address bar and hit the url then i am getting only facebook.com or m.facebook.com and for this reason i am not able to take any action.
I want to get URL only after it is hit in address bar. Also i want to open new tab and close existing tab when it will facebook.com in address bar.
Is there any proper way to do this ?

I have something to add here and how we can improve your solution. It could be better if you accept the following limitations:
The application has an embedded list of supported browsers. Any other browser won't be supported.
The accessibility service will look for an id of an address bar text field and try to intercept the URL from there. It is not possible to catch directly the URL which is going to be loaded. To find this id we should perform a bit of reverse engineering of the target browser: collect all fields by accessibility service and compare their ids and values with user input.
From the previous point, the next limitation is that we are going to support only the current version of the browser. The id could be changed in the future by 3rd-party browser developers and we will have to update our interceptor to continue support. This could be done either by updating an app or by providing the browser package to id mapping by the remote server
We detect either manual user input or redirect on link pressing (because in this case, the new URL will be also visible in an address bar). BTW it is not clear what you have mean when said
I want to get the URL only after it is hit in the address bar.
The last limitation. Despite we are able to intercept the URL and redirect user to another page we can't prevent the site from being loaded or being started to load due to delays of asynchronous parsing a browser app screen. E.g. it is not really safe to protect a user from any access to a fraud site
The implementation:
public class UrlInterceptorService extends AccessibilityService {
private HashMap<String, Long> previousUrlDetections = new HashMap<>();
#Override
protected void onServiceConnected() {
AccessibilityServiceInfo info = getServiceInfo();
info.eventTypes = AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED;
info.packageNames = packageNames();
info.feedbackType = AccessibilityServiceInfo.FEEDBACK_VISUAL;
//throttling of accessibility event notification
info.notificationTimeout = 300;
//support ids interception
info.flags = AccessibilityServiceInfo.FLAG_REPORT_VIEW_IDS |
AccessibilityServiceInfo.FLAG_RETRIEVE_INTERACTIVE_WINDOWS;
this.setServiceInfo(info);
}
private String captureUrl(AccessibilityNodeInfo info, SupportedBrowserConfig config) {
List<AccessibilityNodeInfo> nodes = info.findAccessibilityNodeInfosByViewId(config.addressBarId);
if (nodes == null || nodes.size() <= 0) {
return null;
}
AccessibilityNodeInfo addressBarNodeInfo = nodes.get(0);
String url = null;
if (addressBarNodeInfo.getText() != null) {
url = addressBarNodeInfo.getText().toString();
}
addressBarNodeInfo.recycle();
return url;
}
#Override
public void onAccessibilityEvent(#NonNull AccessibilityEvent event) {
AccessibilityNodeInfo parentNodeInfo = event.getSource();
if (parentNodeInfo == null) {
return;
}
String packageName = event.getPackageName().toString();
SupportedBrowserConfig browserConfig = null;
for (SupportedBrowserConfig supportedConfig: getSupportedBrowsers()) {
if (supportedConfig.packageName.equals(packageName)) {
browserConfig = supportedConfig;
}
}
//this is not supported browser, so exit
if (browserConfig == null) {
return;
}
String capturedUrl = captureUrl(parentNodeInfo, browserConfig);
parentNodeInfo.recycle();
//we can't find a url. Browser either was updated or opened page without url text field
if (capturedUrl == null) {
return;
}
long eventTime = event.getEventTime();
String detectionId = packageName + ", and url " + capturedUrl;
//noinspection ConstantConditions
long lastRecordedTime = previousUrlDetections.containsKey(detectionId) ? previousUrlDetections.get(detectionId) : 0;
//some kind of redirect throttling
if (eventTime - lastRecordedTime > 2000) {
previousUrlDetections.put(detectionId, eventTime);
analyzeCapturedUrl(capturedUrl, browserConfig.packageName);
}
}
private void analyzeCapturedUrl(#NonNull String capturedUrl, #NonNull String browserPackage) {

FCM onReceived method to implement Shortcut Badger library

I found this library (https://github.com/leolin310148/ShortcutBadger) to implement app icon counter badge in android.
badge works when i implement in activity. but i want to implement this when push notification is received. i currently have the initialize code in onMesseageReceived() method in Firebase messaging service but its not working.
see code below:
Thanks for your help
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Logger.i("Received message");
//Shourtcut Badger
int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);
//parseNotification(bundle);
parseNotification(remoteMessage.getData());
if (remoteMessage.getData() != null) {
String str = remoteMessage.getData().get("notification");
String from_user = "";
String message = "";
String name = "";
int type = 0;
if (str != null && str.length() > 0) {
try {
JSONObject jobj = new JSONObject(str);
from_user = jobj.optString("from");
message = jobj.optString("message");
name = jobj.optString("name");
type = Integer.parseInt(jobj.optString("type"));
if (type == LIKE_STATUS) {
handleStatusLikeByFriendPush(jobj, "" + type);
} else if (type == PHOTO_UPDATE) {
handlePhotoUpdateByFriendPush(jobj, "" + type);
} catch (Exception e) {
e.printStackTrace();
}
} else {
message = "";//bundle.getString("message");
from_user = "";//bundle.getString("source");
if (from_user != null && from_user.contains(IMHandler.AT + IMHandler.DOMAIN)) {
from_user = from_user.substring(0, from_user.indexOf(IMHandler.AT));
}
showNotification(from_user, message, type, name);
}
}
}
public void handleStatusLikeByFriendPush(JSONObject jobj, String pushType) {
// method
}
public void handlePhotoLikeByFriendPush(JSONObject jobj, String pushType) {
//method implement
}
}
private void showNotification(String from, String body, int type, String name) {
}
}

After lots of research i understand implementation of this Shortcut badge is not working in FCM service. I Am Able to resolve this issue by simply calling a a custom service from FCM service each time push notification is received and the custom service handles the badge codes and there affter destroys itself.
This way is working perfectly.

How to display popular/trending Youtube videos from the front page on Android

I'm trying to build an android youtube app and to start it off, I would like the main page to display popular videos that are featured on youtube's homepage.
How can I get the necessary info to implement it on my listview? I was digging around the google developers website but could not find any lead as to how to request such information.
any help would be appreciated!
thank you!

Use the chart filter as mentioned here with the value mostPopular. See the sample code on that link for more details.

I have fetched the top trending videos and play them on the app iteself .
First you need to sign in via google , this can be done in simple code structure given below.
private static GoogleAccountCredential credential;
public static final String[] SCOPES = {Scopes.PROFILE,
YouTubeScopes.YOUTUBE};
private static final String PREF_ACCOUNT_NAME = "";
private HttpTransport transport = AndroidHttp.newCompatibleTransport();
private JsonFactory jsonFactory = new GsonFactory();
public static final String APP_NAME = "Your Google Project Name";
credential = GoogleAccountCredential.usingOAuth2(
getActivity().getApplicationContext(),
Arrays.asList(Auth.SCOPES));
credential.setBackOff(new ExponentialBackOff());
scopes =
Lists.newArrayList("https://www.googleapis.com/auth/youtube");
credential.setSelectedAccountName(PREF_ACCOUNT_NAME);
After selecting account , you can load videos into your app - Call loadVideos().
public void loadVideos()
{
if (PREF_ACCOUNT_NAME == null)
{
System.out.println("First need to authorize app");
return;
}
new AsyncTask<Void, Void, List<VideoData>>()
{
#Override
protected List<VideoData> doInBackground (Void...voids){
credential.setSelectedAccountName(name);
YouTube youtube = new YouTube.Builder(transport,
jsonFactory,
credential).setApplicationName(APP_NAME)
.build();
try {
videos = new ArrayList<VideoData>();
VideoListResponse videoListResponse = youtube.videos().
list("snippet,statistics")
.setChart("mostPopular")
.setMaxResults((long)20)
.setRegionCode("IN").
execute();
List<Video> videoList = videoListResponse.getItems();
if (videoList.isEmpty()) {
System.out.println("Can't find a video with ID: ");
return null;
}
for (Video video : videoListResponse.getItems()) {
VideoData videoData = new VideoData();
videoData.setVideo(video);
videos.add(videoData);
}
System.out.println(videoList.size());
return videos;
} catch (final GooglePlayServicesAvailabilityIOException
availabilityException) {
} catch (UserRecoverableAuthIOException
userRecoverableException) {
startActivityForResult(
userRecoverableException.getIntent(),
REQUEST_AUTHORIZATION);
} catch (IOException e) {
Utils.logAndShow(getActivity(), Constants.APP_NAME, e);
}
return null;
}
#Override
protected void onPostExecute (List < VideoData > videos) {
pb.setVisibility(View.GONE);
if (videos == null) {
return;
}
}
}
.execute((Void)
null);
}
VideoClass contains- getter setter for getting data.
public class VideoData {
private Video mVideo;
public Video getVideo() {
return mVideo;
}
public void setVideo(Video video) {
mVideo = video;
}
public String getYouTubeId() {
return mVideo.getId();
}
public String getTitle() {
return mVideo.getSnippet().getTitle();
}
public String getLikes(){
return String.valueOf(mVideo.getStatistics().getLikeCount());
}
public String getViewCount(){
return mVideo.getStatistics().getViewCount().toString();
}
public VideoSnippet addTags(Collection<? extends String> tags) {
VideoSnippet mSnippet = mVideo.getSnippet();
List<String> mTags = mSnippet.getTags();
if (mTags == null) {
mTags = new ArrayList<String>(2);
}
mTags.addAll(tags);
return mSnippet;
}
public String getThumbUri() {
return mVideo.getSnippet().getThumbnails().getHigh().getUrl();
}
public String getWatchUri() {
return "http://www.youtube.com/watch?v=" + getYouTubeId();
}
}
You can manipulate VideoList by applying filter to Videoresponse list.
Filters can be find at Youtube Api v3
For your information below Code Refer to link https://www.googleapis.com/youtube/v3
. App package iteself forms the link.
new YouTube.Builder(transport,
jsonFactory,
credential).setApplicationName(APP_NAME)
.build();
Let me know if you have doubts or need working prototype.

I want to refresh/recreate my activity programatically when getting response from server

I want when server sends some response in form of WebView then immediately my activity gets refreshed and so WebView in form of banner ad.
I write code for display banner ad but ad is showing only when my activity recreated i.e. when I rotate my screen then banner is showing but when it is in same static mode then banner is not showing.
So, please let me know what I will do so that when server gave some response immediately it will be shown on my activity.

for me a call to invalidate() only refresh the view and a call to requestLayout() refresh the view and compute the size of the view in the screen.

You can try to use Activity.recreate(). This method will destroy your current Activity and create a new Activity same way when you rotate device.
Hope this helps.

Access browser url from running background service?

In Android is it possible for a background service to access the url of the web page a user is currently looking at in their Chrome browser? From what ive read so far this is not possible without root access. Im just asking to see if anyone knows if maybe there is some other standard way of doing it?

No, it is not possible if you're not a Chrome developer.

yes you can.
you can use accessibility service
note: if you're not an accessibility app, Google Play will not allow you on the app store if you use this API. If you're writing a personal app its fine.
example:

The implementation:
public class UrlInterceptorService extends AccessibilityService {
