OutOfMemoryError... Whats the solution?

[Vishal Srivastav]

Hi friends,

I am developing an application into which I had to capture an image from the camera and send that Image to a web-service for authentication in the form of byte[]. I got stuck with the camera orientation problem as the preview was coming only in landscape mode. Finally when I solved that, I found that the Image captured comes rotated anti-clockwise when clicked in Portrait mode.

So I thought to capture the image, rotate it, and reconvert it to byte[]. But finally when I am trying to convert the Image, I am getting an OutOfMemoryError, Bitmap exceeds VM budget.

Could you please help me to get out of this? How can I solve it? I have tried to free as much references as I could.

Here is the code below...

if(defaultOrientation == 1) {
				Log.i(TAG, "Picture will be rotated 90 degrees anti-clockwise");

				//Creating bitmap from the source byte[]
				Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
				Log.i(TAG, "Bitmap obtained: " + bmp);

				//getting scales of the image
				int width = bmp.getWidth();
				int height = bmp.getHeight();

				//Creating a Matrix and rotating it to 90 degrees 
				Matrix matrix = new Matrix();
				matrix.postRotate(90);

				//Getting the rotated Bitmap
				Bitmap rotatedBmp = Bitmap.createBitmap(bmp, 0, 0, width, height, matrix, true);
				bmp = null;
				Log.i(TAG, "Rotated Bitmap obtained: " + rotatedBmp);

				//Converting the Bitmap to temporary image and converting it back to byte[]
				FileOutputStream fos = null;
				FileInputStream fis = null;
				byte[] newImage = null;
				try {
					fos = new FileOutputStream(String.format("/sdcard/temp.jpg", System.currentTimeMillis()));
					rotatedBmp.compress(Bitmap.CompressFormat.JPEG, 100, fos);
					fos.write(data);
//					Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
				} catch(FileNotFoundException fnfe) {
					Log.e(TAG, "Cannot find file: " + fnfe);
				} catch(IOException ioe) {
					Log.e(TAG, "Error in input stream: " + ioe);
				} finally {
					if(fos != null) {
						try {
							fos.close();
						} catch(IOException ioE) {
							Log.e(TAG, "Error closing stream: " + ioE);
						}
					}
				}

				try {
					fis = new FileInputStream("/sdcard/temp.jpg");
					newImage = streamToBytes(fis);
				} catch(FileNotFoundException fnfe) {
					Log.e(TAG, "Cannot find file for converting: " + fnfe);
				}

				getImage(newImage);
				Log.d(TAG, "onPictureTaken - JPEG" + image.length);
				Intent serviceIntent = new Intent(context, ValidatorService.class);
				isServiceConnected = bindService(serviceIntent, serviceConnection, Context.BIND_AUTO_CREATE);
				Log.d(TAG, "isServiceConnected :" + isServiceConnected);
			} else {....

Here is the code of the method streamToBytes()...

private static byte[] streamToBytes(InputStream is) {
		ByteArrayOutputStream os = new ByteArrayOutputStream(1024);
		byte[] buffer = new byte[1024];
		int len;
		try {
			while ((len = is.read(buffer)) >= 0) {
				os.write(buffer, 0, len);
			}
		} catch (java.io.IOException ioe) {
			Log.e(TAG, "Error converting to byte[]: " + ioe);
		}
		return os.toByteArray();
}

I have attached the error message in 2 image files...

Waiting for help pals...

Thank you.

You might take a look at "http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/PurgeableBitmapView.html" and specifically how they handle the OutOfMemoryError exception.

Also, "http://developer.android.com/reference/java/lang/ref/SoftReference.html".

Honestly not sure if this will help your particular situation or not, but it seemed informative/worth a read.

You can reduce image size by using BitmapFactory.Options

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;

set options.inSampleSize to some what higher value p(i.e 5) which means high compression that will take care of OutofMemory.
this worked for me.

thanks

The problem is, even after reducing the size of the image to 1/3, the same error is coming.

When I am using the application to click the pic in LANDSCAPE mode, then no error is coming, and what I saw is automatically Image captured has size in KBs. In the sama application, when I am converting the same byte[] to write an image, that Image is at least of size 3.5+ MB.

Decreasing the size of the image to 1/3rd of original is not solving the matter.

Please help.
