Attempting to implement a feature where a user can use their phone camera to take a picture and then it will be uploaded as their profile pic

I'm currently running into an issue with implementing a feature on my app where a user can take a picture using their phone's camera and then have it display as a bitmap image as well as be uploaded to Firebase.
I've seen several similar questions answered on here but nothing seems to be working for me, so I was hoping if someone could give my code a look and have insight for what I might be doing incorrectly.
My general process as of right now is that my "Choose from Gallery" option is working, but my "Take Photo" is not. When clicked in selectProfilePicOption(), I am able to take a picture and confirm it, but the data sent to onActivityResult() continues to get null. I want to be able to pass the taken photo and upload it as a Bitmap to my uploadImageToFirebase() function.
Thanks to all in advance for any assistance!
Here's my current code:
private void selectProfilePicOption(Context context){
final CharSequence[] options = {"Take Photo", "Choose from Gallery", "Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose your profile picture");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if(options[which].equals("Take Photo")){
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, TAKE_IMAGE_REQUEST);
}else if(options[which].equals("Choose from Gallery")){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select image..."), PICK_IMAGE_REQUEST);
}else if(options[which].equals("Cancel")){
dialog.dismiss();
}
}
});
builder.show();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != RESULT_CANCELED) {
switch (requestCode) {
case TAKE_IMAGE_REQUEST:
if(resultCode == RESULT_OK){
data.getExtras().get("data");
File file = new File(Environment.getExternalStorageDirectory().getPath());
Uri uri = Uri.fromFile(file);
try{
System.out.println("attempting to store bitmap");
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
uploadImageToFirebase(bitmap);
} catch (FileNotFoundException e){
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}
}
break;
case PICK_IMAGE_REQUEST:
if (resultCode == RESULT_OK && data != null && data.getData() != null) {
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
uploadImageToFirebase(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
break;
}
}
}
private void uploadImageToFirebase(final Bitmap bitmap){
if(filePath != null){
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading...");
progressDialog.show();
StorageReference ref = mStorageRef.child("images/ProfilePics/" + mUser.getUid());
ref.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
profilePicture.setImageBitmap(bitmap);
Toast.makeText(SetProfileData.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(SetProfileData.this, "Failed " + e.getMessage(), Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(#NonNull UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
progressDialog.setMessage("Uploaded " + (int)progress + "%");
}
});
}
}

The line data.getExtras().get("data"); contains the thumbnail of your captured image, but for some reasons, you are completely ignoring it.
Do it this way,
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != RESULT_CANCELED) {
switch (requestCode) {
case TAKE_IMAGE_REQUEST:
if(resultCode == RESULT_OK){
Bitmap bitmap = (Bitmap) intent.getExtras().get("data") //this line is important
uploadImageToFirebase(bitmap);
} catch (FileNotFoundException e){
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}
}
break;
case PICK_IMAGE_REQUEST:
if (resultCode == RESULT_OK && data != null && data.getData() != null) {
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
uploadImageToFirebase(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
break;
}
}
But beware the image thumbnail you received on onActivityResult() and uploaded to FireBase is not the full resolution image but just a compressed version of it. In order to get the full-size image, you can check out this

Why Camera activity returning null?

I used below codes for taking image from camera and put it in Image View (imgViewAds).
private void BtnPhoto_Click(object sender, EventArgs e)
{
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.SetVmPolicy(builder.Build());
Intent cameraIntent = new Intent(Android.Provider.MediaStore.ActionImageCapture);
var activities = PackageManager.QueryIntentActivities(cameraIntent, 0);
if (activities.Count > 0)
{
addAds.ImageName = Guid.NewGuid().ToString() + ".jpg";
Java.IO.File imageFile = new Java.IO.File(AdsAdapter.ImagePath(addAds.ImageName));
Android.Net.Uri imageUri = Android.Net.Uri.FromFile(imageFile);
cameraIntent.PutExtra(MediaStore.ExtraSizeLimit, 1024*10);
cameraIntent.PutExtra(MediaStore.ExtraOutput, imageUri);
StartActivityForResult(cameraIntent, 0);
}
else
{
Toast.MakeText(this, "Not Camera", ToastLength.Long).Show();
}
}
And here is OnActivityResult the the camare send result here.
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
if (resultCode == Result.Ok && (data != null))
{
Bundle extras = data.Extras;
Bitmap imageBitmap = (Bitmap)extras.Get("data");
imgViewAds.SetImageBitmap(imageBitmap);
MemoryStream stream = new MemoryStream();
imageBitmap.Compress(Bitmap.CompressFormat.Png, 0, stream);
addAds.AdsImage = stream.ToArray();
}
base.OnActivityResult(requestCode, resultCode, data);
}
but the data that sending to OnActivityResult is null and Image did not come to Image View.

When you pass EXTRA_OUTPUT with a URI to write to, the camera intent will be null and the picture is in the URI that you passed in.
so you could simply remove these two lines:
Android.Net.Uri imageUri = Android.Net.Uri.FromFile(imageFile);
cameraIntent.PutExtra(MediaStore.ExtraOutput, imageUri);
note that in this way you get the thumbnail of the image. so if you want the whole image you could use something like this (I haven't tested the code, but you could get the idea):
if (requestCode == CAMERA_REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
addAds.ImageName = Guid.NewGuid().ToString() + ".jpg";
Java.IO.File imageFile = new Java.IO.File(AdsAdapter.ImagePath(addAds.ImageName));
Uri uri = Uri.fromFile(file);
Bitmap bitmap;
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
bitmap = cropAndScale(bitmap, 300); // if you mind scaling
profileImageView.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

Fetching Captured Image sent through Intent

I'm working on a simple project, where I'm suppose to create an application for taking notes. I've sucessfully created the app but now I want to make it possible for the user to take a photo and save it with the note.
I can take the picture, preview it, and then click save.
But the problem is that I'm not able to get the image sent through the intent to my MainActivity class, where the note is suppose to be saved.
So my question is how do I save the note with the picture, please look at the picture that represents how I want my customRow to look like
I have no idea why this happends beacuse I get no errors... And its been driving me nuts.
Any ideas??
Image.class
public void capturePhoto(View view){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri();
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

startActivityForResult(intent, CAPTURE_IMAGE);

setResult(RESULT_OK,i);

}
Memo memo = new Memo(header, bodyText,imageIcon);
customAdapter.add(memo);
customAdapter.notifyDataSetChanged();
} else if (requestCode == Image.EDIT_REQUEST_CODE) {
int position = data.getIntExtra("position", 0);
Memo memo = customAdapter.getItem(position);
memo.header = data.getStringExtra("header");
memo.bodyText = data.getStringExtra("bodyText");
customAdapter.notifyDataSetChanged();
}
}

When you do:
Intent i = new Intent(CheckOutMemo.this, MainActivity.class);
i.putExtra("filePath", fileUri.getPath());
startActivity(i);
You are basically asking to create a new instance of MainActivity. To return to the previous activity while setting the result do this instead:
setResult(RESULT_OK, i);
finish();//finishing activity

Android Studio - Long delay when selecting image through gallery

New to Android Studio, just wondering if anyone can help on this delay when I send an image that is taken from the gallery. Once image is selected there is a long delay until it is actually sent, and for a moment the screen goes black as well.
Here is the code - thanks
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.launch_voip_call) {
Utils.startCall(this, contact);
return true;
} else if (item.getItemId() == R.id.launch_camera) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Pick Image from")
.setCancelable(false)
.setPositiveButton("Camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//camera intent
Intent cameraIntent = new Intent(ConversationActivity.this, CameraActivity.class);
cameraIntent.putExtra("EXTRA_CONTACT_JID", contact.getJid());
startActivity(cameraIntent);
}
})
.setNegativeButton("Gallery", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent();
// Show only images, no videos or anything else
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
// Always show the chooser (if there are multiple options available)
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
});
AlertDialog alert = builder.create();
alert.show();
}
return false;
}
#Override

super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {

try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.WEBP, 5, stream);
byte[] byteArray = stream.toByteArray();
// Log.d(TAG, String.valueOf(bitmap));
EventBus.getDefault().post(new MessageEvent.SendMessage(contact.getJid(), byteArray, ""));
} catch (IOException e) {
e.printStackTrace();
}
}
}
#OnTextChanged(R.id.compose)
public void onMessageChanged(CharSequence s) {
sendButton.setVisibility(s.length() > 0 ? View.VISIBLE : View.INVISIBLE);
}
#OnClick(R.id.send)
public void onSend(final View view) {
String message = composeText.getText().toString().trim();
if (!message.isEmpty()) {

On Activity result is on Main Thread.. Compressing Image can take time.. Try to use AsyncTask to achieve compression in background and then send image in background as well.. Dont perform Compression on MainThread thats why you are getting long delay..
Let me know if you need code??
public class ImageSendingAsync extends AsyncTask<Bitmap,Void,Void> {
#Override
protected Void doInBackground(Bitmap... params) {
try {
Bitmap bitmap = params[0];
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.WEBP, 5, stream);
byte[] byteArray = stream.toByteArray();
// Log.d(TAG, String.valueOf(bitmap));
EventBus.getDefault().post(new MessageEvent.SendMessage(contact.getJid(), byteArray, ""));
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
//This will go in Activity Result
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
new ImageSendingAsync().execute(bitmap);
}

I think the compress takes a while and thats why ur MainThread are not able to draw the Layout -> Black Screen.
maybe test the time it take to compress the pic.
if the time is to long, use ASyncTask.
[...]
long timeStart = System.currentTimeMillis();
bitmap.compress(Bitmap.CompressFormat.WEBP, 5, stream);
long timeEnd = System.currentTimeMillis();
Log.e("resizePicture Timer", "resize took " + (timeEnd - timeStart) + "ms");

Deleting/Removing a ParseFile from ParseUser (Android)

I am trying to remove a ParseFile from a ParseUser. The ParseFile is a profile picture that was created, and I would like to provide my users will the ability to change there profile picture when convenient to them.
I am looking for a way to delete the old ParseFile associated with the profile picture, and just store a new one.
I cannot seem to get the .remove("photo"); method to work properly, and am not sure if I am going about this the wrong way. What would be the best method to do something like this?
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == RESULT_LOAD_IMAGE) {
Bundle extras2 = data.getExtras();
if (extras2 != null) {
Bitmap bitmap = extras2.getParcelable("data");
ivProfilePic.setImageBitmap(bitmap);
final ParseUser currentUser = ParseUser.getCurrentUser();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bitmapByte = stream.toByteArray();
final ParseFile profilePicture = new ParseFile(
"profilePicture", bitmapByte);
profilePicture.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
if (e != null) {
} else {
// check to see if ParseFile exists, if it does
// delete it and set new ParseFile
currentUser.remove("photo");
currentUser.put("photo", profilePicture);
currentUser.saveInBackground();
updateViewsWithProfileInfo();
}
}
});
}
}
}

if (resultCode != RESULT_OK) {
return;
}
This line of code stops everything from working properly. If you remove this the ParseFile is removed / updated properly.
