将图库图像加载到应用程序中，加载第5或第6张图片后出现内存错误

Question

I am constantly getting Out Of Memory Errors after loading 5 or 6 gallery images into my app.

I am calling bitmap.recycle() after every image is done loading so wondering why I am still getting OOM error?

This is how I handle gallery images:

1. press button from inside app that goes to gallery to select image
2. goes back to app, and copies the gallery image to app's external files directory
3. compress and rotate the image

4. load image into ImageView

    public static void compressAndRotateImage(Context context, String filename) { try { File file = new File(context.getExternalFilesDir(null), filename); // Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; BitmapFactory.decodeStream(new FileInputStream(file), null, o); // The new size we want to scale to final int REQUIRED_SIZE = 720; // Find the correct scale value. It should be the power of 2. int scale = 1; while (o.outWidth/scale/2 >= REQUIRED_SIZE && o.outHeight/scale/2 >= REQUIRED_SIZE) { scale*=2; } // Decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize = scale; Bitmap bm = BitmapFactory.decodeStream(new FileInputStream(file), null, o2); // Get orientation of picture ExifInterface exif = null; try { exif = new ExifInterface(context.getExternalFilesDir(null) + "/" + filename); } catch (IOException e1) { e1.printStackTrace(); } int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, -1); Log.i("ORIENTATION", Integer.toString(orientation)); // Rotate image to portrait based on taken orientation Matrix matrix = new Matrix(); if (orientation == 6) { matrix.postRotate(90); } else if (orientation == 3) { matrix.postRotate(180); } else if (orientation == 8) { matrix.postRotate(270); } bm = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true); // Save and compress file FileOutputStream fos = new FileOutputStream(file); bm.compress(Bitmap.CompressFormat.JPEG, 90, fos); try { fos.flush(); fos.close(); } catch (IOException e) { e.printStackTrace(); } bm.recycle(); System.gc(); } catch (FileNotFoundException e) { e.printStackTrace(); } 

   }

   Copies gallery image to app external files dir

    private void copyGalleryImage(Uri uri) { String realPath = ImageHandler.getRealPathFromUri(this, uri); File galleryFile = new File(realPath); imgFilename = ImageHandler.getImageFilename(this); File file = new File(getExternalFilesDir(null), imgFilename); GlobalMethods.copyFile(galleryFile, file); Log.i("IMAGE COPIED TO INTERNAL", imgFilename); ImageHandler.compressAndRotateImage(this, imgFilename); FragmentManager fm = getFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); NewPictureFragment fragment = NewPictureFragment.newInstance(imgFilename); ft.replace(R.id.fragment_container, fragment); ft.addToBackStack(null); ft.commit(); }

Use android:largeHeap="true" in Manifest File. Maybe this solve your problem.
