I know this question has been asked here and answered but for some reasons, provided solutions are not working for me.
So here is how I'm trying to do this. I have two buttons in my layout one to open gallery and other to upload the images.
Defined members
int SELECT_PICTURES = 1;
ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
Uri imageUri;
int up = 0;
int k =0;
Gallery button code
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURES);
On Activity result code
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == SELECT_PICTURES) {
if (resultCode == MainActivity.RESULT_OK) {
if (data.getClipData() != null) {
int count = data.getClipData().getItemCount();
Log.i("count", String.valueOf(count));
int currentItem = 0;
while (currentItem < count) {
imageUri = data.getClipData().getItemAt(currentItem).getUri();
Log.i("uri", imageUri.toString());
mArrayUri.add(imageUri);
currentItem = currentItem + 1;
}
Log.i("listsize", String.valueOf(mArrayUri.size()));
} else if (data.getData() != null) {
String imagePath = data.getData().getPath();
}
}
}
}
Upload button code
StorageReference filepath = FirebaseStorage.getInstance().getReference().child("gpic");
while (up < mArrayUri.size()){
// error is pointing to this line, line 82
filepath.child(mArrayUri.get(k).getLastPathSegment()).putFile(mArrayUri.get(k)).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadURL = taskSnapshot.getDownloadUrl();
Toast.makeText(TestingActivity.this, downloadURL.toString(), Toast.LENGTH_SHORT).show();
up++;
k++;
}
});
}
}
The above code uploads one image and then crashes with the following error

Found what was causing the problem. I was incrementing the variables "up" and "k" within the onSuccessListener. That might be changing their values before uploading the URI, so I incremented them outside the onSuccessListener and it worked perfectly fine.
Upload button code
StorageReference filepath = FirebaseStorage.getInstance().getReference().child("gpic");
while (up < mArrayUri.size()){
filepath.child(mArrayUri.get(k).getLastPathSegment()).putFile(mArrayUri.get(k)).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadURL = taskSnapshot.getDownloadUrl();
Toast.makeText(TestingActivity.this, downloadURL.toString(), Toast.LENGTH_SHORT).show();
}
});
up++;
k++;
}
}
