Android Firebase upload image not working

I am trying to use the following code to have a user select an image, and after the image is selected, it is automatically uploaded to my Firebase storage. I initialized the variable storageReference in the OnCreate function
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(requireContext());
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
startActivityForResult(intent, 1);
}
else if (options[item].equals("Choose from Gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(intent.createChooser(intent, "Select Image"), 2);
}
else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
#SuppressLint("LongLogTag")
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// If the image is uploaded properly and the resultcode is OK
// The imagePreview is updated and the image is uploaded
if(requestCode == 1 || requestCode == 2) {
if (resultCode == Activity.RESULT_OK && data != null && data.getData() == null) {
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(requireContext().getContentResolver(), filePath);
imagePreview.setImageBitmap(bitmap);
uploadImage();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
private void uploadImage()
{
if (filePath != null) {
// Code for showing progressDialog while uploading
ProgressDialog progressDialog = new ProgressDialog(getContext());
progressDialog.setTitle("Uploading...");
progressDialog.show();
// Defining the child of storageReference
StorageReference ref = storageReference.child(mAuth.getCurrentUser().toString());
// adding listeners on upload
// or failure of image
ref.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// Image uploaded successfully
// Dismiss dialog
progressDialog.dismiss();
Toast.makeText(getActivity(), "Image Uploaded!!", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
// Error, Image not uploaded
progressDialog.dismiss();
Toast.makeText(getContext(),"Failed " + e.getMessage(),Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
// Progress Listener for loading
// percentage on the dialog box
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
progressDialog.setMessage("Uploaded " + (int)progress + "%");
}
});
}
}
My guess is that the uploadImage function is not being called but I am not sure why.

I figured it out, the issue was with this line
if (resultCode == Activity.RESULT_OK && data != null && data.getData() == null)
data.getData() == null
should be:
data.getData() != null

Intent camera crash

I'm now making a simple android app. It's just allow user to take an Photo and then show it.
When i test it in Virtual device, it's ok. But when i download apk to my android device, after i take a photo in Back camera, the app has stopped and return to main menu. Just problem in Back Camera.
In addition, in virtual device, after taking photo, the photo will show successfully. But it's empty in my phone
In MainActivity, i click on "Take Photo", it will start the camera and same my image to folder. Then it send the path of Photo to the next activity and show it.
This is my MainActivity
public class MainActivity extends AppCompatActivity {
private static final int REQUEST_ID_IMAGE_CAPTURE = 100;
Button TakePhoto, InsertPhoto, Exit;
String mCurrentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(imageFileName,".jpg",storageDir);
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TakePhoto = (Button) findViewById(R.id.button);
InsertPhoto = (Button) findViewById(R.id.button3);
Exit = (Button) findViewById(R.id.button2);
//Start Camera
TakePhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
System.out.println(ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = Uri.fromFile(photoFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(intent,REQUEST_ID_IMAGE_CAPTURE);
}
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_ID_IMAGE_CAPTURE) {
if (resultCode == RESULT_OK) {
//Bitmap bp = (Bitmap)data.getExtras().get("data");
//ByteArrayOutputStream stream = new ByteArrayOutputStream();
// bp.compress(Bitmap.CompressFormat.PNG, 100, stream);
// byte[] images = stream.toByteArray();
File imgFile = new File(mCurrentPhotoPath);
if(imgFile.exists()){
System.out.println("This is file"+mCurrentPhotoPath.toString());
Intent Show = new Intent(MainActivity.this, ShowPhoto.class);
Show.putExtra("image",imgFile);
startActivity(Show);
}
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Action canceled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Action Failed", Toast.LENGTH_LONG).show();
}
}
}
}
This is The ShowPhoto Activity
public class ShowPhoto extends Activity {
private LinearLayout Image;
Button Back,Next;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_photo);
Image=(LinearLayout)findViewById(R.id.linearLayout);
//Get Image from previous Activity
File image = (File)getIntent().getExtras().get("image");
Bitmap bmp = BitmapFactory.decodeFile(image.getAbsolutePath());
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageBitmap(Bitmap.createScaledBitmap(bmp, bmp.getWidth()*2, bmp.getHeight()*2, true));
Image.addView(imageView);
}
}
This is what's in my logcat when i run app
enter image description here
enter image description here

Use should ask for the permission at runtime and declare the permission in Manifest
if (ContextCompat.checkSelfPermission(getContext(),

getContext(), Manifest.permission.CAMERA)) {
} else {
ActivityCompat.requestPermissions((Activity) getContext(),

Attempt to invoke virtual method 'android.os.Parcelable android.os.Bundle.getParcelable(java.lang.String)' null object reference

I am making an app in which a feature that user can upload images and video to server
it was working well on activity but now I want to use it in a fragment. I try to code effectively, efficiently and I am not getting any error during compiling and my app runs successfully but when I click on fragment it shows "unfortunately app has stopped " and in log cat I am getting this error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.os.Parcelable android.os.Bundle.getParcelable(java.lang.String)' on a null object reference

How to add picture to my own gallery

I want to take a photo from my App and save this in my own gallery. After this I need the full name of the photo. With
private void dispatchTakePictureIntent(int actionCode) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
this.startActivityForResult(takePictureIntent, actionCode);
}
the photo will be saved in the default gallery. If I read the documentation right than I can set the name with
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, "MyFileName");
How can I create my own gallery and save the image there instead of the default gallery?
After taking the photo and saving in a gallery the result function will be called. How can I get besides the image the full name of the file.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode){
case actionCode:
// get the image
InputStream stream = this.getContentResolver().openInputStream(data.getData());
// How to get the file name?
break;
default:
}
}
After setting the name with the extra the onActivityResult function won't be called. Without this extra I get the image to utilize.

Capture image like this:
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
private Uri fileUri;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
getOutputMediaFileUri like this:
public static final int MEDIA_TYPE_IMAGE = 1;
public static final int MEDIA_TYPE_VIDEO = 2;
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(int type){
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "MyCameraApp");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
Log.d("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else if(type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"VID_"+ timeStamp + ".mp4");
} else {
return null;
}
return mediaFile;
}
and get saved image fileUri like this:
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Video captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Video saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the video capture
} else {
// Video capture failed, advise user
}
}
}
