high quality images taken from phone error-Collection of common programming errors
i am selecting in the gallery “BIG SIZE image and capture image high quality ” then Force close error see also following code and error …Thanks

Looks like you run out of memory. I solved this problem by writing the images to the sd before processing. I can’t send you the code right now but later. Acutally processing images takes lots of memory. So you should consider resizing the bitmap before you process the image.
Hint: You might not be able to write to the bitmap. You have to make a copy of that bitmap so you can access and edit the pixels.
This is why I had to make a copy of the bitmap to my sd, because writing the copy to the memory would cause an exception.
Try this:
- Load the image
- write a copy to the sd
- flush
- load the copy and try to process
EDIT: Here you go… How to get large images from the camera and process the bitmap:
rivate void openCamera() { String _path = Environment.getExternalStorageDirectory() + File.separator + "temp.JPEG"; tempFile = new File(_path); outputFileUri = Uri.fromFile(tempFile); bitmap = null; // start default camera Intent cameraIntent = new Intent( android.provider.MediaStore.ACTION_IMAGE_CAPTURE); cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outputFileUri); startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); } private void process() { Bitmap editableBitmap = processor.processImage(bitmap); imgView.setImageBitmap(editableBitmap); // finish(); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { ready = false; if (requestCode == CAMERA_PIC_REQUEST) { // bitmap = BitmapFactory.decodeFile(_path); try { bitmap = MediaStore.Images.Media.getBitmap( getApplicationContext().getContentResolver(), outputFileUri); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } if (imgView == null) { imgView = (ImageView) findViewById(R.id.imageView1); } process(); } }Convert Bitmap to mutable bitmap so you can edit the pixels (I think I got this somwhere from pastebin but it’s no magic)
public static Bitmap convertToMutable(Bitmap imgIn) { try { // this is the file going to use temporally to save the bytes. // This file will not be a image, it will store the raw image data. File file = new File(Environment.getExternalStorageDirectory() + File.separator + "temp.tmp"); // Open an RandomAccessFile // Make sure you have added uses-permission // android:name="android.permission.WRITE_EXTERNAL_STORAGE" // into AndroidManifest.xml file RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rw"); // get the width and height of the source bitmap. int width = imgIn.getWidth(); int height = imgIn.getHeight(); Config type = imgIn.getConfig(); // Copy the byte to the file // Assume source bitmap loaded using options.inPreferredConfig = // Config.ARGB_8888; FileChannel channel = randomAccessFile.getChannel(); MappedByteBuffer map = channel.map(MapMode.READ_WRITE, 0, imgIn.getRowBytes() * height); imgIn.copyPixelsToBuffer(map); // recycle the source bitmap, this will be no longer used. imgIn.recycle(); System.gc();// try to force the bytes from the imgIn to be released // Create a new bitmap to load the bitmap again. Probably the memory // will be available. imgIn = Bitmap.createBitmap(width, height, type); map.position(0); // load it back from temporary imgIn.copyPixelsFromBuffer(map); // close the temporary file and channel , then delete that also channel.close(); randomAccessFile.close(); // delete the temp file file.delete(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return imgIn; }
