I have created an app that basically takes a picture and saves it to the gallery. The only problem is that after the picture is taken it takes you to the screen where you can preview it with the two buttons that say okay and cancel. Once you click okay, the app quits. The image is still saved to the gallery but I want the app to stay open. I also want the app to display a bitmap of the image on an imageView that I have.
Here is my MainActivity.java

Button btn = findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dispatchTakePictureIntent(); <- Line 34
}
});
}
static final int REQUEST_IMAGE_CAPTURE = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
// I AM UNSURE WHAT CODE TO PUT HERE. DOES ANYONE KNOW WHAT I SHOULD BE PUTTING HERE?
}
// Continue only if the File was successfully created
if (photoFile != null) {
//This is where the error is occurring but I do not know why.
Line 56 -> Uri photoURI = FileProvider.getUriForFile(this, "com.example.app", photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
ImageView imageView = findViewById(R.id.imageView);
imageView.setImageBitmap(imageBitmap);
}
}
String currentPhotoPath;
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, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = image.getAbsolutePath();
return image;
}
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(currentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
}
Here is my error message

Recently I have been working on android studio, I built a python image classification model and want to integrate it with an app. But when I click on predict button, the app crashes. Would be helpful if I can get the idea as to where things are going wrong.
Attached is the code and the error it throws -

Need suggestions as to what's going on and how to resolve it. I'm using android studio arctic fox 2020.3.1 patch 3.
The logcat already told you that it crashed at the setText() call. You called
tv.setText((int) outputFeature0.getFloatArray()[0]);
The int in setText(int) refers to a Resource ID defined in the string.xml (R.string.xxx).
If you are not getting the string from res, you should use setText(CharSequence) instead.
You probably want
tv.setText(String.format("%f",outputFeature0.getFloatArray()[0]));
(change "%f" to any decimal points or format you want)
I'm creating a view model in my activity in order to add an object to the database via method. But the view model is representing an empty table, and it's causing this stack trace and complete crash of the application:

This is happening as soon as I enter said activity. The other view models that have records in the database are created with no problem, but the other ones that lack any object in the database fail to create too. Do I purposedly need to add a record in order to create those?

public void insert(int i, int j) { repository.insertObject(i,j); }
public void delete(PathologyUser obj) { repository.deleteObject(obj); }
}
I don't quite remember anything about not being able to create view models with empty tables in the documentation, maybe I'm missing something?
Instead of the line:
pathologyUserViewModel = new ViewModelProvider(this).get(PathologyUserViewModel.class);
You can use:
pathologyUserViewModel = new ViewModelProvider
.AndroidViewModelFactory(this.getApplication())
.create(PathologyUserViewModel.class);
Or,
pathologyUserViewModel = ViewModelProvider(
this,
ViewModelProvider.AndroidViewModelFactory(application)
).get(PathologyUserViewModel::class.java)
If you look through the log, you are trying to access the database on the main thread :-
Caused by: java.lang.IllegalStateException: Cannot access database on the main thread since it may potentially lock the UI for a long period of time
at the line :-
pathologyUsers = repository.getAllObjects();
You either need to run this on another thread OR alternately (and not recommended) allow it to run on the main thread which can be done by using:-
.allowMainThreadQueries()
when building the room database. e.g. :-
Room.databaseBuilder(context, TheDatabase::class.java, "thedatabasefile.db")
.allowMainThreadQueries() //<<<<<<<<<< allow main thread run
.build()
Do I purposedly need to add a record in order to create those?
As long as you are handling the returned Lists correctly and not assuming they are not empty, there should be no problem.
I am using Android Intent to take a photo.
startActivityForResult(intent, 0);
This opens the native camera and i can take a picture.
In the Activity where the picture is returned to , in the onActivityResult method , I can get a hold of the returned Bitmap like so.
if (requestCode == 0 && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
I then wish to convert this to a Mat to do some openCV image processing.
I am attempting to convert like this.
Mat src = new Mat(imageBitmap.getHeight(), imageBitmap.getWidth(), CvType.CV_8UC4);
Utils.bitmapToMat(imageBitmap, src);
The line above causes a crash with the following stack trace .

After searching i found the following post.
http://answers.opencv.org/question/52722/what-is-the-correct-way-to-convert-a-mat-to-a-bitmap/
Which says that.
mat is a valid input Mat object of the types 'CV_8UC1', 'CV_8UC3' or 'CV_8UC4'.
bmp is a valid Bitmap object of the same size as the Mat and of type 'ARGB_8888' or 'RGB_565'.
As you can see in the constructor for the Mat I supply these args.
I have checked the config of the imageBitmap , which confirms that it is indeed
a 'RGB_565'.
What am i missing here? I dont understand why this does not work.
Thanks in advance.

When debugging this method call :
Mat src = new Mat(imageBitmap.getHeight(), imageBitmap.getWidth(),

nativeObj = n_Mat(rows, cols, type);
this n_Mat is declared like so.

The application no longer crashes and functions as expected.

UCrop is working fine, but you are starting it the wrong way, if you specify the same argument for source and destination, the onActivityResult will be called immediately. and obviously with no result, fix:
1. specify different source and destination
UCrop.of(fileUri, dstUri).start(this);
2. add the code to handle the response from uCrop. in my tutorial
https://youtu.be/glwM0cAUV4A, the code in onActivityResult is not perfect but it works.
There is a strange behaviour of assigning/modifying instance variable of the class inside Button OnClick() handlers.
As shown below, the instance variable "CurrentFile" is modified inside imgBtn.setOnClickListener() handlers. But when this variable is accessed in onActivityResult() method, this variable contains the value "null".
According to my understanding, the activity "GetPicActivity" will not be destroyed till the Camera activity returns. So, the instance variable "CurrentFile" should not be null.
Please help, if I am missing some basics.

Steps what I intend to do:
1, Create a temporary file in External storage for the destination of Camera picture
2, Start Camera to take a picture by passing the URI of temporary file
3, OnActivityResult() from camera, return the (temporary) File path to previous activity for further process
But here what I see is,
As soon as the Camera is started & picture is taken, the GetPicActivity is created again. Because of this, the instance variable "CurrentFile" will be null & in OnActivityResult() , I could not get the File path of temporary file.
Why is the GetPicActivity destroyed after starting Camera?
When the camera is started, the Camera appears in the screen orientation "Landscape".
Even the orientation of already existing activity stack is changed to "Landscape" itseems.
So, When the result of Camera is returned to GetPicActivity method OnActivityResult(), the GetPicActivity is created again. But now, the instance variable "CurrentFile" is null. This, gives a NullPointerException.
