Отображение снимка с камеры: java.lang.OutOfMemoryError at android.graphics.BitmapFactory.nativeDecodeStream (Native Method)

Question

Я пытаюсь показать снимок, сделанный камерой, и иногда он работает, но обычно это дает мне ошибку:

java.lang.OutOfMemoryError

Я попытался решения из нескольких вопросов, но я никогда не сделать его работу

Это мой код:

mImageView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      dispatchTakePictureIntent(); 
     } 
    }); 

dispatchTakePictureIntent

String mCurrentPhotoPath; 

private void dispatchTakePictureIntent() { 
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    if (cameraIntent.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 
      Log.i("", "IOException"); 
     } 
     // Continue only if the File was successfully created 
     if (photoFile != null) { 
      cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile)); 
      startActivityForResult(cameraIntent, REQUEST_TAKE_PHOTO); 
     } 
    } 
} 

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 = Environment.getExternalStoragePublicDirectory(
      Environment.DIRECTORY_PICTURES); 
    File image = File.createTempFile(
      imageFileName, // prefix 
      ".jpg",   // suffix 
      storageDir  // directory 
    ); 

    // Save a file: path for use with ACTION_VIEW intents 
    mCurrentPhotoPath = "file:" + image.getAbsolutePath(); 
    return image; 
} 


@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) { 
     try { 
      Bitmap mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)); 
      mImageView.setImageBitmap(mImageBitmap); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

Answer 1

Наконец я получил его на работу, решение с использованием растрового изображения, как это:

Bitmap b = BitmapUtility.decodeSampledBitmapFromResource(image.getAbsolutePath(), 540, 360); 

BitmapUtility:

public class BitmapUtility { 

public static Bitmap decodeSampledBitmapFromResource(String path, int reqWidth, int reqHeight) { 

    // First decode with inJustDecodeBounds=true to check dimensions 
    final BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inJustDecodeBounds = true; 
    BitmapFactory.decodeFile(path,options); 

    // Calculate inSampleSize 
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); 

    // Decode bitmap with inSampleSize set 
    options.inJustDecodeBounds = false; 
    return BitmapFactory.decodeFile(path, options); 
} 
private static int calculateInSampleSize(
     BitmapFactory.Options options, int reqWidth, int reqHeight) { 
    // Raw height and width of image 
    final int height = options.outHeight; 
    final int width = options.outWidth; 
    int inSampleSize = 1; 

    if (height > reqHeight || width > reqWidth) { 

     final int halfHeight = height/2; 
     final int halfWidth = width/2; 

     // Calculate the largest inSampleSize value that is a power of 2 and keeps both 
     // height and width larger than the requested height and width. 
     while ((halfHeight/inSampleSize) > reqHeight 
       && (halfWidth/inSampleSize) > reqWidth) { 
      inSampleSize *= 2; 
     } 
    } 

    return inSampleSize; 
} }
