So my application is an Image to text and text-to-speech app. The idea is to scan text from any source and it is read out to the user. The basic functionality of the app is working, when I click on "Capture Image" on the main screen, it opens the camera, takes a pic, and extracts text. But I also added another function where the user can manually add pictures from his gallery by clicking on the gallery icon.

So the problem is when I select the gallery and choose my own image, it won't add to the main image view canvas, instead, it crashes the application. There is no error in the code, but it just won't run.

Here are 20-second clips I have attached on Google Drive to show you the precise problem for a better understanding for you all. I’m very close!

https://drive.google.com/drive/folders/18oCeFkVEvi1xPv_O4DEI3EZz0TtVyZ36?usp=sharing

Kindly please let me know what the problem is, as Android studio does not give any warnings or errors when the project is run.

Please open the Google Drive link for better understanding, the below code is mainly for the image icon shown on the top right, in the action bar to import images from Gallery and camera.

What I have tried:

MAIN ACTIVITY JAVA
Java
public class MainActivity extends AppCompatActivity implements TextToSpeech.OnInitListener {
    ImageView imageView;
    TextView textView;
    private TextToSpeech engine;




 
    private void showImageImportDialog() {

        String[] items = {"Camera", "Gallery"};
        AlertDialog.Builder dialog = new AlertDialog.Builder(this);

        //Set TITLE
        dialog.setTitle("Select Image");

        dialog.setItems(items, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                if (which == 0) {
                    //Camera Option Clicked
                    if (!checkCameraPermission()) {

"Kindly please let me know what the problem is"
The problem is somewhere in all that (400+ lines) code, but there is far too much for anyone here to be able to tell what it is or even where. You need to do some debugging and provide more detailed information for anyone to be able to help you.

Yes you are right. Im sorry about that, that's the problem with Android Studio. Anyways I have updated it a little now, is it okay?

You need "something" to "catch" any errors.
