prendre une photo et l'enregistrer en utilisant android studio

Question

J'ai écrit un programme qui peut prendre une photo. Le problème est quand j'essaie de l'enregistrer dans DIRECTORY_PICTURES je ne peux pas trouver l'image que j'ai prise dans le répertoire d'images quel est le problème avec mon code ?. Le programme que j'écrit ouvrir l'appareil photo sans problème et je peux prendre l'image, mais avec succès il n'y a pas d'image en images répertoire

ImageView mImageView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    mImageView=(ImageView)findViewById(R.id.imageView) ; 
} 


static final int REQUEST_IMAGE_CAPTURE=1; 
public void bucapture(View view) { 
    Intent takePictureIntent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    if(takePictureIntent.resolveActivity(getPackageManager())!=null){ 
     startActivityForResult(takePictureIntent,REQUEST_IMAGE_CAPTURE); 
    } 

} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if(requestCode==REQUEST_IMAGE_CAPTURE && resultCode==RESULT_OK){ 
     Bundle extras=data.getExtras(); 
     Bitmap imageBitmap=(Bitmap) extras.get("data"); 
     mImageView.setImageBitmap(imageBitmap); 
     try { 
      createImageFile(); 
      galleryAddpic(); 

     }catch (Exception ex){ 
      ex.printStackTrace(); 
     } 

    } 
} 

String mCurrentPhotpPath; 
//create image name 
private File createImageFile() throws IOException { 
    String timeStamp=new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); 
    String imageFileName="JPGE"+timeStamp+"_"; 
    File storgeDir= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); 
    File image=File.createTempFile(imageFileName,".jpg",storgeDir); 
    mCurrentPhotpPath="file:"+image.getAbsolutePath(); 
    return image; 
} 


//save image 
private void galleryAddpic(){ 
    Intent mediaScanIntent=new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); 
    File f=new File(mCurrentPhotpPath); 
    Uri contentUri=Uri.fromFile(f); 
    mediaScanIntent.setData(contentUri); 
    this.sendBroadcast(mediaScanIntent); 

    } 
}

//This is one of the best can take photo full size in android an save it but create temp file that what exactly is in your code. it doesn't work some of custom phones like some model of samsung & Mi there you can check for file 
//and you have to use Intent Action picker intent for that. 

private URI mImageUri; 

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 
File photo; 
try 
{ 
    // place where to store camera taken picture 
    photo = this.createTemporaryFile("picture", ".jpg"); 
    photo.delete(); 
} 
catch(Exception e) 
{ 
    Log.v(TAG, "Can't create file to take picture!"); 
    Toast.makeText(activity, "Please check SD card! Image shot is impossible!", 10000); 
    return false; 
} 
mImageUri = Uri.fromFile(photo); 
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri); 
//start camera intent 
activity.startActivityForResult(this, intent, MenuShootImage); 

private File createTemporaryFile(String part, String ext) throws Exception 
{ 
File tempDir= Environment.getExternalStorageDirectory(); 
tempDir=new File(tempDir.getAbsolutePath()+"/.temp/"); 
if(!tempDir.exists()) 
{ 
    tempDir.mkdirs(); 
} 
return File.createTempFile(part, ext, tempDir); 
} 

//Then after image capture intent finished to work - just grab your picture from imageUri using following code: 

public void grabImage(ImageView imageView) 
{ 
this.getContentResolver().notifyChange(mImageUri, null); 
ContentResolver cr = this.getContentResolver(); 
Bitmap bitmap; 
try 
{ 
    bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr,  mImageUri); 
    imageView.setImageBitmap(bitmap); 
} 
catch (Exception e) 
{ 
    Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show(); 
    Log.d(TAG, "Failed to load", e); 
    } 
} 


//called after camera intent finished taking photo 
    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{ 
if(requestCode==MenuShootImage && resultCode==RESULT_OK) 
{ 
    ImageView imageView; 
    this.grabImage(imageView); 
} 
super.onActivityResult(requestCode, resultCode, intent); 
}
