Impossible de récupérer l'image capturée de la caméra

Question

Je suis en train de construire une application de caméra simple dans Android, ce qui lancerait une caméra intentionnellement sur le clic d'un bouton. L'intention de la caméra doit alors cliquer sur une image qui sera affichée ultérieurement dans ImageView présent dans MainActivity. Le problème est cependant que je suis capable de capturer l'image, mais dès que l'image est capturée au lieu d'afficher l'image, l'application se bloque soudainement.

Voici mon code pour l'application:

MainActivity.java

package com.example.suzancruz.cameraapplicaton; 

import android.content.Intent; 
import android.graphics.Bitmap; 
import android.provider.MediaStore; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ImageView; 


public class MainActivity extends AppCompatActivity { 


    static final int REQUEST_IMAGE_CAPTURE = 123; 
    ImageView myImageView; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

    } 

    //Launching the camera 
    public void launchCamera(View view){ 
     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     //Take a picture and pass results along to onActivityResult 
     startActivityForResult(intent, REQUEST_IMAGE_CAPTURE); 
    } 

    //If you want to return the image taken 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK){ 
      //Get the photo 
      Bundle extras = data.getExtras(); 
      Bitmap photo = (Bitmap) extras.get("data"); 
      myImageView.setImageBitmap(photo); 
     } 
    } 
}

essayer cette `publique void onTakeImg() {

values = new ContentValues(); 
    values.put(MediaStore.Images.Media.TITLE, "Image"); 
    values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera"); 
    imageUri = getActivity().getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); 
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); 
    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) { 
     startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); 
    } 

} 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 

    switch (requestCode) { 
     case REQUEST_IMAGE_CAPTURE: 
      if (resultCode == RESULT_OK) { 
       try { 
        mBitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), imageUri); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 
       onImageAvailable(mBitmap, requestCode); 
       Img.setImageBitmap(mBitmap); 
           } 
      break; 

    } 
} 

void onImageAvailable(Bitmap imageBitmap, int requestCode) { 
    String output = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString() + "/.immigration/temp/"; 
    File f = new File(output); 
    if (!f.exists()) { 
     f.mkdirs(); 
    } 

    String filename = output + "Image.jpg"; 

    File fileDelete = new File(filename); 

    if (fileDelete.exists()) { 
     if (fileDelete.delete()) { 
      System.out.println("file Deleted :" + filename); 
     } else { 
      System.out.println("file not Deleted :" + filename); 
     } 
    } 

    try { 
     FileOutputStream out = new FileOutputStream(filename); 
     Matrix matrix = new Matrix(); 
     if (imageBitmap.getWidth() < imageBitmap.getHeight()) { 
      matrix.postRotate(90); 
     } 
     mBitmap = Bitmap.createBitmap(imageBitmap, 0, 0, imageBitmap.getWidth(), imageBitmap.getHeight(), matrix, true); 
     mBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out); 
     out.close(); 
     Log.d("Ar", "Ole"); 
    } catch (IOException e) { 
     e.printStackTrace(); 
     Log.d("Ar", e.toString()); 
    } 

    File fdelete = new File(imageUri.getPath()); 
    if (fdelete.exists()) { 
     if (fdelete.delete()) { 
      System.out.println("file Deleted :" + imageUri.getPath()); 
     } else { 
      System.out.println("file not Deleted :" + imageUri.getPath()); 
     } 
    } 

}`
