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

For a camera activity, result code is -1 in onActivityResult(). How to proceed debugging?

None of the submissions here deal with negative result code. I know it means that the task failed, but I have no idea how or why it failed. The app opens the camera and I'm able to take a picture.
btnN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
captureImage(v);
}
});
The function definitions are as given below.
public void captureImage(View view) {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
File imageFile = null;
try {
imageFile = getImageFile();
} catch (IOException e) {
e.printStackTrace();
}
if (imageFile != null) {
Uri imageUri = FileProvider.getUriForFile(this, "com.example.testingproject.fileprovider", imageFile);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(cameraIntent, 1);
}
System.out.println("imageFile length:" + imageFile.length());
}
}
In the above function, I've even tried sending request code as 2. Same functionality, I'm able to click a picture, but same issue.
public File getImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmsss").format(new Date());
String imageName = "jpg_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File imageFile = File.createTempFile(imageName, ".jpg", storageDir);
currentImagePath = imageFile.getAbsolutePath();
System.out.println("currImPath: " + currentImagePath);
return imageFile;
}
The much needed onActivityResult() code is below
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
try {
System.out.println("reqCode: "+requestCode+" resCode: "+resultCode);
switch (requestCode) {
case 0: {
if (resultCode == RESULT_OK) {
File file = new File(currentImagePath);
Bitmap bitmap = MediaStore.Images.Media.getBitmap(MainActivity.this.getContentResolver(), Uri.fromFile(file));
if (bitmap != null) {
//...Do your stuffs
Toast.makeText(MainActivity.this, "Bitmap NOT null", Toast.LENGTH_SHORT).show();
imgView.setImageBitmap(bitmap);
}
else
{
Toast.makeText(MainActivity.this,"BitmapNull",Toast.LENGTH_SHORT).show();
}
}
break;
}
default: Toast.makeText(MainActivity.this,"result code not okay",Toast.LENGTH_SHORT).show(); break;
}
} catch (Exception error) {
error.printStackTrace();
}
}
The sysout in log is below
2020-05-01 13:52:24.644 10014-10014/com.example.testingproject I/System.out: reqCode: 1 resCode: -1

-1 is equal to RESULT_OK. It means the task completed successfully

When you look into the code. -1 is actully status code for RESULT_OK
public static final int RESULT_OK = -1;
Now you've set requestCode as 1 in this line
startActivityForResult(cameraIntent, 1);
So in your OnActivityResult which shows
reqCode: 1 resCode: -1
is Correct.

Androind ImageView in Fragment

I am trying to put an image on my fragment, but the image is not showing up. I am certain that it was working just yesterday but now it is not. Any help is appreciated.
This code is in my Fragment:
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
mUser = (User) getArguments().getSerializable(ARGS_USER);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.fragment_picture_picker, container, false);
mImageView = v.findViewById(R.id.imageView);
mSelectImageButton = v.findViewById(R.id.select_image);
mSelectImageButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, IMG_REQUEST);
}
});
return v;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == IMG_REQUEST && resultCode == Activity.RESULT_OK && data != null){
Uri path = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), path);
mImageView.setImageBitmap(bitmap);
mImageView.setVisibility(View.VISIBLE);
mUser.setProfilePicture(bitmap);
}catch(IOException e){
e.printStackTrace();
}
}
}

Actually you are not using the Volley. Please change the heading of your question. You are accessing the Gallery and showing the image inside the imageView. Use the below code for accessing the image from camera as well as gallery.
if (action.equals("CAMERA")) {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA)

// states, but all we need to know is we can neither read nor write
mExternalStorageAvailable = false;
}
return mExternalStorageAvailable;
}
}
action is like what you want to do. ACTION_REQUEST_GALLERY and ACTION_REQUEST_CAMERA use some integer constants like 100 and 101. profileImage is your ImageView.

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??

Memo memo = customAdapter.getItem(position);
memo.header = data.getStringExtra("header");

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

how can I upload a photo from the gallery to parse.com?

I am trying to upload a photo from the gallery into my parse cloud but I can't figure it out here's my code and what I've done so far .
I've looked everywhere still can't find a solution , can't upload the photo :\
help me please.
