Get uri from camera intent in android

To just get the thumbnail, you can use this:

val imageBitmap = data.extras.get("data") as Bitmap

To get the full picture:
See the specific steps from here (official docs)

You can read more from the docs.

If your device does not respect cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, you still can use

Uri imageUri = data.getData();

in onActivityResult(int requestCode, int resultCode, Intent data). But in most cases, the problem is that RAM is limited, and the system destroys your activity to give enough memory to the camera app to fulfill your intent. Therefore, when the result is returned, the fields of your activity are not initialized, and you should follow Amit's suggestion and implement onSavedInstance() and onRestoreInstanceState().

First of all make sure that your directory is created......

final String dir =  Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+ "/Folder/";
     File newdir = new File(dir); 
     newdir.mkdirs();

on button click call this function.

private void capturarFoto() {
 String file = dir+DateFormat.format("yyyy-MM-dd_hhmmss", new Date()).toString()+".jpg";


File newfile = new File(file);
            try {
                newfile.createNewFile();
            } catch (IOException e) {}       

            Uri outputFileUri = Uri.fromFile(newfile);

            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);

            startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
        Log.d("Demo Pic", "Picture is saved");


    }
}

Make sure You add permission in manifest

<uses-permission android:name="android.permission.CAMERA"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
