Firebase Dynamic Link New Install Events

I want to get the event of New install or App open/re-open events in my Android App whenever user click on any dynamic link.
Following events are captured in Analytics as per documentation:
dynamic_link_first_open
dynamic_link_app_open
But I can't find any way to get these from sample listener.

I have found solution to my above question. Sharing details here.
Below code is tested from PlayStore also.
You can get mentioned two events through pendingDynamicLinkData callback object received from addOnSuccessListener.
Complete code to get link and associated Dynamic link data here.
FirebaseDynamicLinks.getInstance()
.getDynamicLink(getIntent())
.addOnSuccessListener(this, pendingDynamicLinkData -> {
// Get deep link from result (may be null if no link is found)
try {
Uri deepLink = null;
if (pendingDynamicLinkData != null) {
deepLink = pendingDynamicLinkData.getLink();
sendInstallDetailToAPI(pendingDynamicLinkData.getExtensions());
}
CgUtils.showLog(TAG, "getDynamicLink:onSuccess" + deepLink);
} catch (Exception e) {
CgUtils.showLog(TAG, "getDynamicLink:onFailure" + e);
}
})
.addOnFailureListener(this, e -> CgUtils.showLog(TAG, "getDynamicLink:onFailure" + e));
Below method to send the Dynamic Link data to your backend API if you want.
private void sendInstallDetailToAPI(Bundle deepBundle) {
Bundle deepLinkData = deepBundle.getBundle("scionData");
if (deepLinkData != null) {
Bundle appReOpenBundle = deepLinkData.getBundle("dynamic_link_app_open");
boolean isInstall = false;
String medium = "", source = "", campaign = "", shortLink = "";
if (appReOpenBundle != null) {
medium = appReOpenBundle.getString("medium", "NA");
source = appReOpenBundle.getString("source", "NA");
campaign = appReOpenBundle.getString("campaign", "NA");
shortLink = appReOpenBundle.getString("dynamic_link_link_id", "NA");
}
Bundle appFirstOpenBundle = deepLinkData.getBundle("dynamic_link_first_open");
if (appFirstOpenBundle != null) {
isInstall = true;
medium = appFirstOpenBundle.getString("medium", "NA");
source = appFirstOpenBundle.getString("source", "NA");
campaign = appFirstOpenBundle.getString("campaign", "NA");
shortLink = appFirstOpenBundle.getString("dynamic_link_link_id", "NA");
}
// Send ABOVE detail to your respective APIs
}
}
Now If isInstall flag is true that means it's first time open after install else reopen.

What does this mean download_url = task.getResult().getStorage().getDownloadUrl().toString()

StorageReference filePath = employee_photo_profile_reference.child(current_employee_ID+".jpg");
filePath.putFile(result_uri).addOnCompleteListener( new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (task.isSuccessful()){
Toast.makeText(activity_setup.this,"Profile Photo stored Successfully.", Toast.LENGTH_SHORT).show();
if (task.getResult() != null){
final String download_url = task.getResult().getStorage().getDownloadUrl().toString();

That line of code is buggy. It's incorrectly using getDownloadUrl(). This is a very common mistake - you can't just call toString() on the result to get a URL.
getDownloadUrl() returns a Task object which you can use to fetch the download URL asynchronously.
The correct usage is demonstrated here: How to get URL from Firebase Storage getDownloadURL
I also suggested reading the documentation.

Upload images according to position no firebase

I'm creating a system for storing multiple image links in firestore, and it's been working, I select from the gallery and upload them as List it is in the order that it is going to the bank (firestore ), because it matters to me, I select for example the images 1,2,3, and when I save their link in the firestore it gets 2,1,3 or 3,1, 2 or 3,2,1 never in the order I loaded, it seems to be according to the lightest image, as saved according to the position I loaded? I've been breaking my head with this for a few days.
already to get each image from List.get(i) to save but to no avail.
I'm saving like this in firestore ->
list_img [
0 link_img
1 link_img
2 link_img]
firestore scheme
upload from gallery
GalleryConfig config = new GalleryConfig.Build()
.limitPickPhoto(50)
.singlePhoto(false)
.hintOfPick("this is pick hint")
.filterMimeTypes(new String[]{})
.build();
GalleryActivity.openActivity(Pag_producao_hq.this, reqCode, config);
upload
private void upload_Fotos_selecionadas(Uri uri, final int totalimg, int i) {
Log.i("sdsd77", String.valueOf(i));
final StorageReference ImageFolder = FirebaseStorage.getInstance().getReference().child("imagens");
String nomeImagem = UUID.randomUUID().toString();
final StorageReference imagename = ImageFolder
.child("HQ")
.child(identificadorUsuario)
.child(nomeImagem);
arrayListImageRef.add(ImageFolder); //arraylist of type StorageRef
arrayListImageRef.add(imagename);
imagename.putFile(uri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
imagename.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String urlConvertida = uri.toString();
lista_url.add(urlConvertida);
if(lista_url.size()==totalimg){
Map<String, Object> new_imagens = new HashMap<>();
new_imagens.put("list_img", lista_url);
db.collection("HQ")
.document(getId())
.collection("Imagens")
.add(new_imagens);
dialog.dismiss();
finish();
}
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
if (!isFinishing()) {
dialog.dismiss();
}
Toast.makeText(getApplicationContext(), exception.getMessage(), Toast.LENGTH_LONG).show();
}
});
}

Cloud Firestore does not list document as the same order of insertion. Auto IDs are not time related. You will need to add a timestamp field and query your data using order by this field.

Add query parameters to link in firebase dynamic link

I create dynamic link and I want to send some specific parameter, like:
"https://mydynamiclink/?link=" + link + "&msgid=" + id + "&apn=myapn".
link field looks like "https://play.google.com/store/apps/details/?id=com.myApp&msgid=myId&apn=myapn"
When I open my app after taping on this link - I receive PendingDynamicLinkData and can get link from it, but not some custom data. (pendingDynamicLinkData.getLink() returns my link without "&msgid=..." - I'm getting string "https://play.google.com/store/apps/details/?id=com.myApp")
How can I add my msgid field and get it after all?

I've found solution
String query = "";
try {
query = URLEncoder.encode(String.format("&%1s=%2s", "msgid", id), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
final String link = "https://play.google.com/store/apps/details/?id=com.myApp" + query;
After such encoding pendingDynamicLinkData.getLink() returns me https://play.google.com/store/apps/details/?id=com.myApp&msgid=myId

Accepted answer didn't work out fine for me, all i needed to do was check if the link was for a user's profile and not a blog post, so i can redirect to my ProfileActivity instead.
private void generateDynamicLink() {
//build link normally and add queries like a normal href link would
String permLink = getLink() + "?route=profile&name=" + getProfileName()
+ "&category=" + getUserPracticeCategory()
+ "&picture=" + getProfilePicture();
FirebaseDynamicLinks.getInstance().createDynamicLink()
.setLink(Uri.parse(permLink))
.setDynamicLinkDomain(Constants.DYNAMIC_LINK_DOMAIN)
.setAndroidParameters(new
DynamicLink.AndroidParameters.Builder().build())
.setSocialMetaTagParameters(
new DynamicLink.SocialMetaTagParameters.Builder()
.setTitle("Enter Title")
.setDescription("Enter Desc here")
.setImageUrl(Uri.parse(getProfilePicture()))
.build())
.buildShortDynamicLink()
.addOnCompleteListener(this, task -> {
if (task.isSuccessful()) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT,task.getResult().getShortLink());
intent.setType("text/plain");
startActivity(intent);
} else {
Utils.snackBar(tvAddress, "Failed to Generate Profile Link, Try
Again");
}
});
}
and when a user navigates into my app using the generated link, it goes to a post detail activity, because i made that activity the only browsable activity in my manifest. i then have to use the route query to determine if the incoming link is a blog post or a shared user profile.
private void retrieveDynamicLink() {
FirebaseDynamicLinks.getInstance().getDynamicLink(getIntent())
.addOnSuccessListener(this, pendingDynamicLinkData -> {
if (pendingDynamicLinkData == null) {
retrieveLocalIntent();
} else {
Toast.makeText(context, "Resolving Link, Please Wait...", Toast.LENGTH_LONG).show();
if (pendingDynamicLinkData.getLink().getQueryParameter("route") != null) {
if (Objects.requireNonNull(pendingDynamicLinkData.getLink().getQueryParameter("route")).equalsIgnoreCase("profile")) {
try {
Uri uri = pendingDynamicLinkData.getLink();
String permLink = uri.toString().split("\\?")[0];
Intent intent = new Intent(this, ProfileActivity.class);
intent.putExtra(ProfileActivity.PROFILE_NAME, uri.getQueryParameter("name"));
intent.putExtra(ProfileActivity.PROFILE_CATEGORY, uri.getQueryParameter("category"));
intent.putExtra(ProfileActivity.PROFILE_PICTURE, uri.getQueryParameter("picture"));
intent.putExtra(Utils.POST_PERMLINK, permLink);
startActivity(intent);
this.finish();
} catch (NullPointerException e) {
Toast.makeText(context, "Unable to View User Profile", Toast.LENGTH_SHORT).show();
}
}
} else {
postHrefLink = pendingDynamicLinkData.getLink().toString();
getPostDetail.getData(postHrefLink);
}
}
})
.addOnFailureListener(this, e ->
retrieveLocalIntent()
);
}
Hope this helps.

1 First Change your Dynamic Link in firebase console from http://exampleandroid/test to http://exampleandroid/test?data
2. You send the query paramter data with this
DynamicLink dynamicLink = FirebaseDynamicLinks.getInstance().createDynamicLink()
// .setLink(dynamicLinkUri)
.setLink(Uri.parse("http://exampleandroid/test?data=dsads"))
.setDomainUriPrefix("https://App_Name.page.link")
// Open links with this app on Android
.setAndroidParameters(new DynamicLink.AndroidParameters.Builder().build())
// Open links with com.example.ios on iOS
.setIosParameters(new DynamicLink.IosParameters.Builder("com.appinventiv.ios").build())
.buildDynamicLink();
dynamicLinkUri = dynamicLink.getUri();

Let's say that You want to create the following URL:
https://www.myawesomesite.com/turtles/types?type=1&sort=relevance#section-name
For this you can do following
Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
.authority("www.myawesomesite.com")
.appendPath("turtles")
.appendPath("types")
.appendQueryParameter("type", "1")
.appendQueryParameter("sort", "relevance")
.fragment("section-name");
String myUrl = builder.build().toString();

Upload Multiple images and wait for completion before returning, android and firebase

Hello I am trying to upload multiple images, wait for them to return, compile the download uri's into an object and send it back to my activity. I am using this as reference for upload, firebase. So far i have this
private void saveStepWithImages(#NonNull Step step, Callback callback){
if(step.getStepId() == null){
Collection<Image> images = step.getImages().values();
List<Task<Uri>> taskArrayList= new ArrayList<>();
for (Image i: images) {
taskArrayList.add(uploadImageTask(new ImageUtils().StringToBitMap(i.getImageUrl()), i.getImageReference()));
}
Tasks.whenAll(taskArrayList).addOnCompleteListener(task -> {
Uri downloadUri = task.getResult(); // throws an error because task.getResult is void
});
}else{
updateStepInFirebase(step, callback);
}
}
and in my upload images
private Task<Uri> uploadImageTask(final Bitmap bitmap, String prepend){
final StorageReference ref = mStorageRef.child( prepend );
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] data = baos.toByteArray();
UploadTask uploadTask = ref.putBytes(data);
bitmap.recycle();
return uploadTask.continueWithTask(task -> {
bitmap.recycle();
return ref.getDownloadUrl();
});
}
Step is a custom object i created it contains a Map of images with a string as the key and the value being an image. My image class looks like this
public class Image implements Parcelable {
private String imageUrl;
private String imageReference;
public void Image(){
}
//Setters and getters here;
}
Any suggestions would be really appreciated. Thanks!

The key for solving this problem is to use Tasks's whenAllSuccess() method:
Returns a Task with a list of Task results that completes successfully when all of the specified Tasks complete successfully.
Insted of Tasks's whenAll() method:
Returns a Task that completes successfully when all of the specified Tasks complete successfully.
Please see more informations about Tasks class.

You can upload multiple files to firebase by nesting all the calls in one array, and adding each call to the Task API of firebase:
Define the reference and an array of tasks
StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
List<Task> myTasks = new ArrayList<>();
In this example im using a map that contains each file an its corresponding storage destination
for (Map.Entry<String, Attachment> entry : storageRouteMap.entrySet()) {
String path = entry.getKey();
final Attachment localAtt = entry.getValue();
Uri fileUri = localAtt.getMyUri();
I will put each task in the array of tasks, for a file i have three tasks, one for uploading the file, one for getting the url of the storage and one for writing the metadata in the real time database.
final StorageReference ref = mStorageRef.child(path);
ThreadPerTaskExecutor executor = new ThreadPerTaskExecutor();
UploadTask t1 = ref.putFile(fileUri);
myTasks.add(t1);
Task<Uri> t2 = t1.continueWithTask(executor,new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful()) {
throw task.getException();
}
return ref.getDownloadUrl();
}
});
myTasks.add(t2);
Task<Void> t3 = t2.continueWithTask(executor,new Continuation<Uri, Task<Void>>() {
#Override
public Task<Void> then(#NonNull Task<Uri> task) throws Exception {
if (!task.isSuccessful()) {
throw task.getException();
}
Attachment uploadAtt = new Attachment();
uploadAtt.name = localAtt.name;
uploadAtt.url = task.getResult().toString();
uploadAtt.type = localAtt.type;
String idAtt = UtilFirebase.getAttachmentReference().push().getKey();
UtilLog.LogToConsole(TAG," => "+postId+" => "+uidAuthor+" =>"+idAtt);
return UtilFirebase.getAttachmentReference()
.child(postId)
.child(uidAuthor)
.child(idAtt)
.setValue(uploadAtt);
}
}).continueWith(executor,new VideoTransaction(communityId,localAtt.size,localAtt.type));
myTasks.add(t3);
}
Finally i will see if all the tasks where completed or if there was an error, either way this will communicate the result to the main thread.
Task finish = Tasks.whenAll((Collection) myTasks);
finish.addOnCompleteListener(new ThreadPerTaskExecutor(), new OnCompleteListener() {
#Override
public void onComplete(#NonNull Task task) {
if (task.isSuccessful()) {
callback.onComplete();
} else {
callback.onError(task.getException().toString());
}
}
});
