android image view crashes when big image is chosen for display

问题

Many have asked this question before and got the right way to resolve it. but somehow its not working out for me. My app crashes when I try to choose a large image for display. I have tried to reduce the size by scaling it as well using BitmapFactory. This is not working. Please help.

my code:

    public void browse(View v){
            @SuppressWarnings("unused")
            int id = v.getId();
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            intent.addCategory(Intent.CATEGORY_OPENABLE);
            startActivityForResult(intent, REQUEST_CODE);
        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            InputStream stream = null;

            if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK) {

                Uri imgUri = data.getData();
                logopath = getPath(imgUri);

                //This block is to show the view
                    try {
                        if(bitmap != null){
                            bitmap.recycle();
                        }
                            stream = getContentResolver().openInputStream(data.getData());
                            bitmap = BitmapFactory.decodeStream(stream);
                            iv.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 100, 100, true));
                            //bitmap = shrinkBitmap(logopath,100,100);
                            //iv.setImageBitmap(bitmap);
                        } 
                    catch (FileNotFoundException e) {
                            e.printStackTrace();
                    }
                finally{
                    if (stream != null) {
                        try {
                                stream.close();
                            } 
                        catch (Exception e) {
                                e.printStackTrace();
                        }
                    }
                }

            }
        }

        private Bitmap shrinkBitmap(String file, int height, int width) {
            BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
            bmpFactoryOptions.inJustDecodeBounds = true;
            Bitmap bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);

            int heightRatio = (int)Math.ceil(bmpFactoryOptions.outHeight/(float)height);
            int widthRatio = (int)Math.ceil(bmpFactoryOptions.outWidth/(float)width);

            if (heightRatio > 1 || widthRatio > 1)
            {
             if (heightRatio > widthRatio)
             {
              bmpFactoryOptions.inSampleSize = heightRatio;
             } else {
              bmpFactoryOptions.inSampleSize = widthRatio; 
             }
            }

            bmpFactoryOptions.inJustDecodeBounds = false;
            bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
         return bitmap;
        }

回答1:

Bitmap ThumbImage = ThumbnailUtils.extractThumbnail(BitmapFactory.decodeFile(imagePath), THUMBSIZE, THUMBSIZE);

回答2:

Use the sampling technique. More the sampling value, less the image size. Hope you will be able to handle the OutOfMemory error, which causes due to low heap size rendering large images sizes.

BitmapFactory.Options options = new BitmapFactory.Options();
                options.inSampleSize = 15;



Bitmap bm = BitmapFactory.decodeStream(stream);

if you are using android 3.0 onward use android:largeHeap="true" tag within application tag in manifest file..

 application
        android:allowBackup="true"
        android:icon="@drawable/app_icon"
        android:label="@string/app_name"
        android:theme="@style/AppTheme>
        android:largeHeap="true"
