Answer 1

try this way...

@Override
 protected void onActivityResult(int requestCode, int resultcode, Intent intent)
 {
     int orientation =0;
     super.onActivityResult(requestCode, resultcode, intent);

     if (requestCode == 1)
     {
         if (intent != null && resultcode == RESULT_OK)
         {             

               Uri selectedImage = intent.getData();

               String[] filePathColumn = {MediaStore.Images.Media.DATA};
               Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
               cursor.moveToFirst();
               int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
               String filePath = cursor.getString(columnIndex);
               Log.v("log","filePath is : "+filePath);

               cursor.close();
               try 
               {
                    ExifInterface exif = new ExifInterface(filePath);
                     orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
                    //Toast.makeText(getApplicationContext(), ""+orientation, 1).show();
                    Log.v("log", "ort is "+orientation);

               } 
               catch (IOException e)
               {
                   e.printStackTrace();
               }

               if(bmp != null && !bmp.isRecycled())
               {
                   bmp = null;               
               }

               File f = new File(filePath);

               bmp = decodeFile(f,300,420);
       }
     }
   }

and this is the decode function...

public static Bitmap decodeFile(File f,int WIDTH,int HIGHT){
     try {
         //Decode image size
         BitmapFactory.Options o = new BitmapFactory.Options();
         o.inJustDecodeBounds = true;
         BitmapFactory.decodeStream(new FileInputStream(f),null,o);

         //The new size we want to scale to
         final int REQUIRED_WIDTH=WIDTH;
         final int REQUIRED_HIGHT=HIGHT;
         //Find the correct scale value. It should be the power of 2.
         int scale=1;
         while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT)
             scale*=2;

         //Decode with inSampleSize
         BitmapFactory.Options o2 = new BitmapFactory.Options();
         o2.inSampleSize=scale;
         return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
     } catch (FileNotFoundException e) {}
     return null;
 }

Answer 2

The image you are trying to load is too large. That it causing the heap size to grow rapidly and filling it up, which is causing the app to crash. Try to downsize the image and then load it.

You can use the following code snippet:

public static Bitmap getResizedBitmap(Bitmap image, int newHeight, int newWidth) {
    int width = image.getWidth();
    int height = image.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // create a matrix for the manipulation
    Matrix matrix = new Matrix();
    // resize the bit map
    matrix.postScale(scaleWidth, scaleHeight);
    // recreate the new Bitmap
    Bitmap resizedBitmap = Bitmap.createBitmap(image, 0, 0, width, height,
            matrix, false);
    return resizedBitmap;
}

Add below function into your java file and call this function in onActivityResult() after getting image path or image uri, it will solve your problem.

private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
    // Decode image size
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(
            getContentResolver().openInputStream(selectedImage), null, o);

    // The new size we want to scale to
    final int REQUIRED_SIZE = 100;

    // Find the correct scale value. It should be the power of 2.
    int width_tmp = o.outWidth, height_tmp = o.outHeight;
    int scale = 1;
    while (true) {
        if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
            break;
        }
        width_tmp /= 2;
        height_tmp /= 2;
        scale *= 2;
    }

    // Decode with inSampleSize
    BitmapFactory.Options o2 = new BitmapFactory.Options();
    o2.inSampleSize = scale;
    return BitmapFactory.decodeStream(
            getContentResolver().openInputStream(selectedImage), null, o2);
}

Try this :

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

        switch (requestCode) {
        case SELECT_PHOTO:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = imageReturnedIntent.getData();
                try {
                    picImageView.setImageBitmap(decodeUri(selectedImage));
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            }
        }
    }

And then declare the following function :

private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(
                getContentResolver().openInputStream(selectedImage), null, o);

        final int REQUIRED_SIZE = 100;

        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
            if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
                break;
            }
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(
                getContentResolver().openInputStream(selectedImage), null, o2);
    }

Thanks.
