How to avoid Out of Memory Error while handling Imageviews

In my app i am selecting a picture from storage or taking a picture using camera and it will set in to an image view.When doing this i got Out of memory Error ,to avoid this I used this method.But it is not working,can anyone help to solve this issue .Or can anyone suggest any other method to handle this issue.
public void decodeFile(String filePath) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 1024;
// 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 < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
bitmap = BitmapFactory.decodeFile(filePath, o2);
imgView.setImageBitmap(bitmap);
}

I would suggest to use a library to handle the loading, caching and displaying of images.
They are easy to use and you dont have to take care of image downsizing etc.
In my projects i use the Universal Image Loader by nostra13.
It is pretty easy to implement and offers a lot of features like memory and disk caching. You should give it a try.

Get Bitmap orginal size without Out of memory

İt is classical question but i didn't find answer for me. I work bitmaps in my project . apply filter,crop.. Problem is out of memory. I need keep many bitmap (approximate 20-30 bitmap) on ram.
I use this method for get image consecutively in gallery, But it is not get orginal size.
public static Bitmap getImageWithoutOutOfMemory(String filePath,int requiredSize) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
o.inMutable = true;
o.inPreferredConfig = Bitmap.Config.ARGB_8888;
BitmapFactory.decodeFile(filePath, o);
// The new size we want to scale to
final int REQUIRED_SIZE = requiredSize;
// 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 < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
Bitmap img = BitmapFactory.decodeFile(filePath, o2);
return img;
}
so how can i get orginal image without out of memory exception.

u can try resize bitmap using decodeSampledBitmapFromResource method

The function in its current form chooses a size that ensures the image is scaled to be strictly smaller than a required size.
At lease change:
if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE) break;
to
if (width_tmp <= REQUIRED_SIZE && height_tmp <= REQUIRED_SIZE) break;
If the image is 'naturally' with the required size it will actually be returned half size.
If there are other problems please post a MVCE.

Reduce image file size in Android (image type unknown)

I want to let the user choose how much they want to reduce the image file size by, could be low, medium or high then upload the image to a server That part is easy.
Next part is the actual reduction of file size. I'm getting the image URI, I want to reduce the file image file size, the image type could be png, jpg or something else.
I'm aware of Bitmap.compress(), is this the only way to implement or is there an existing open source library?

Bitmap bitmap;
bitmap = MyBitmapFactory.decodeFile(PATHTOPICT, UPLOAD_REQUIRED_SIZE);
if (bitmap != null) {
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
with the method (found with google):
public static Bitmap decodeFile(String filePath, final int REQUIRED_SIZE) {
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, o);
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp <= REQUIRED_SIZE && height_tmp <= REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
Bitmap bitmap = BitmapFactory.decodeFile(filePath, o2);
return bitmap;
}
if something get NULL, its no image/.
scale by power 2 is recommended!!!

Suggestions to avoid bitmap Out of Memory error

I am working on an android application. The application has a view containing lots of image. I had an error, I will try to give as much information as possible hoping someone can give me some suggestions.
The application was working great on all the local testings. However, I received lots of crashes from users: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
This is the stack trace
0 java.lang.OutOfMemoryError: bitmap size exceeds VM budget
1 at android.graphics.Bitmap.nativeCreate(Native Method)
2 at android.graphics.Bitmap.createBitmap(Bitmap.java:507)

8 at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:359)
9 at android.graphics.BitmapFactory.decodeResource(BitmapFactory.java:385)
My biggest problem is that I was not able to reproduce the issue locally even on old devices.
I have implemented lots of things to try to resolve this:
No memory leaks: I made sure there is no memory leaks at all. I removed the views when I dont need them. I also recycled all the bitmaps and made sure the garbage collector is working as it should. And I implemented all the necessary steps in the onDestroy() method
Image size scaled correctly: Before getting the image I get its dimension and calculate the inSampleSize.
Heap size: I also detect the Max Heap size before getting the image and make sure there is enough space. If there is not enough I rescale the image accordingly.
Code to calculate the correct inSampleSize
public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight)
{
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if(height > reqHeight || width > reqWidth)
{
if(width > height)
{
inSampleSize = Math.round((float) height / (float) reqHeight);
}
else
{
inSampleSize = Math.round((float) width / (float) reqWidth);
}
}
return inSampleSize;
}
Code to get the bitmap
// decodes image and scales it to reduce memory consumption
private static Bitmap decodeFile(File file, int newWidth, int newHeight)
{// target size
try
{
Bitmap bmp = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), Uri.fromFile(file));
if(bmp == null)
{
// avoid concurrence
// Decode image size
BitmapFactory.Options option = new BitmapFactory.Options();
// option = getBitmapOutput(file);
option.inDensity = res.getDisplayMetrics().densityDpi < DisplayMetrics.DENSITY_HIGH ? 120 : 240;
option.inTargetDensity = res.getDisplayMetrics().densityDpi;
if(newHeight > 0 && newWidth > 0)
option.inSampleSize = calculateInSampleSize(option, newWidth, newWidth);
option.inJustDecodeBounds = false;
byte[] decodeBuffer = new byte[12 * 1024];
option.inTempStorage = decodeBuffer;
option.inPurgeable = true;
option.inInputShareable = true;
option.inScaled = true;
bmp = BitmapFactory.decodeStream(new FileInputStream(file), null, option);
if(bmp == null)
{
return null;
}
}
else
{
int inDensity = res.getDisplayMetrics().densityDpi < DisplayMetrics.DENSITY_HIGH ? 120 : 240;
int inTargetDensity = res.getDisplayMetrics().densityDpi;
if(inDensity != inTargetDensity)
{
int newBmpWidth = (bmp.getWidth() * inTargetDensity) / inDensity;
int newBmpHeight = (bmp.getHeight() * inTargetDensity) / inDensity;
bmp = Bitmap.createScaledBitmap(bmp, newBmpWidth, newBmpHeight, true);
}
}
return bmp;
}
catch(Exception e)
{
Log.e("Error calling Application.decodeFile Method params: " + Arrays.toString(new Object[]{file }), e);
}
return null;
}
Code to calculate image size based on Heap size for older devices
private void calculateImagesSize()
{
// only for android older than HoneyComb that does not support large heap
if(Build.VERSION.SDK_INT < Constants.HONEYCOMB)
{
long maxHeapSize = Runtime.getRuntime().maxMemory();
long maxImageHeap = maxHeapSize - 10485760;
if(Application.getResource().getDisplayMetrics().densityDpi >= DisplayMetrics.DENSITY_XHIGH)
{
maxImageHeap -= 12 * 1048576;
}
if(maxImageHeap < (30 * 1048576))
{
int screenHeight = Math.min(Application.getResource().getDisplayMetrics().heightPixels, Application.getResource()
.getDisplayMetrics().widthPixels);
long maxImageSize = maxImageHeap / 100;
long maxPixels = maxImageSize / 4;
long maxHeight = (long) Math.sqrt(maxPixels / 1.5);
if(maxHeight < screenHeight)
{
drawableHeight = (int) maxHeight;
drawableWidth = (int) (drawableHeight * 1.5);
}
}
}
}
I think the problem is with the Heap, maybe sometimes the os doesn't allow the application to use the maxheapsize. Also my biggest problem is that I was not able to reproduce the issue, so when I try a fix I have to wait a little to see if users are still getting the error.
What more could I try to avoid Out of memory issues? Any suggestions would be greatly appreciated. Thanks a lot

just use this function to decode...this is perfect solution for your error..because i also getting same error and i got this solution..
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;
}

Hi you have to decode the file . for this try with the following method.
public static Bitmap new_decode(File f) {
// decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
o.inDither = false; // Disable Dithering mode
o.inPurgeable = true; // Tell to gc that whether it needs free memory,
// the Bitmap can be cleared
o.inInputShareable = true; // Which kind of reference will be used to
// recover the Bitmap data after being
// clear, when it will be used in the future
try {
BitmapFactory.decodeStream(new FileInputStream(f), null, o);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// Find the correct scale value. It should be the power of 2.
final int REQUIRED_SIZE = 300;
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 1.5 < REQUIRED_SIZE && height_tmp / 1.5 < REQUIRED_SIZE)
break;
width_tmp /= 1.5;
height_tmp /= 1.5;
scale *= 1.5;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
// o2.inSampleSize=scale;
o.inDither = false; // Disable Dithering mode
o.inPurgeable = true; // Tell to gc that whether it needs free memory,
// the Bitmap can be cleared
o.inInputShareable = true; // Which kind of reference will be used to
// recover the Bitmap data after being
// clear, when it will be used in the future
// return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
try {
// return BitmapFactory.decodeStream(new FileInputStream(f), null,
// null);
Bitmap bitmap= BitmapFactory.decodeStream(new FileInputStream(f), null, null);
System.out.println(" IW " + width_tmp);
System.out.println("IHH " + height_tmp);
int iW = width_tmp;
int iH = height_tmp;
return Bitmap.createScaledBitmap(bitmap, iW, iH, true);
} catch (OutOfMemoryError e) {
// TODO: handle exception
e.printStackTrace();
// clearCache();
// System.out.println("bitmap creating success");
System.gc();
return null;
// System.runFinalization();
// Runtime.getRuntime().gc();
// System.gc();
// decodeFile(f);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}

By Reducing/Scale size of the Image you can get rid out of the Out of Memory Exception,
Try this
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 6;
Bitmap receipt = BitmapFactory.decodeFile(photo.toString(),options); //From File You can customise on your needs.

I wrote a summary of suggestions in another StackOverFlow question: Android: BitmapFactory.decodeStream() out of memory with a 400KB file with 2MB free heap

actually the problem is with the development os. In android unlike iOS , google people develop this based on camera resolution. Bitmaps take up a lot of memory, especially for rich images like photographs.Different cameras captures images with different pixels(different mobiles have different camera pixel capacity). Here in android based on that pixels only the captured image will take memory. so obviously a high resolution image will not uploaded by a phone with low pixel capacity.
In android os allocates utmost 16MB to every application. If the uploaded image takes more than this then java.lang.OutofMemoryError: bitmap size exceeds VM budget will occur and application crashes.
refer this
http://developer.android.com/training/displaying-bitmaps/index.html

If u want to avoid OOM, u can catch OOM and increase the sampleSize until the image can be resolved:
private Bitmap getBitmapSafely(Resources res, int id, int sampleSize) {
// res = context.getResources(), id = R.drawable.yourimageid
Bitmap bitmap = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPurgeable = true;
options.inSampleSize = sampleSize;
try {
bitmap = BitmapFactory.decodeResource(res,
id, options);
} catch (OutOfMemoryError oom) {
Log.w("ImageView", "OOM with sampleSize " + sampleSize, oom);
System.gc();
bitmap = getBitmapSafely(res, id, sampleSize + 1);
}
return bitmap;
}
Hope it helps.
It is not suitable to catch the Error, just a workaround.

android : bitmap size exceeds VM budget

I am using android Camera. Also using auto focusing feature. After capturing image more then 10 times getting the following exception:
Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
my source code is following:
PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
try {
// Bitmap bmp = BitmapFactory.decodeStream(new
// ByteArrayInputStream(data));
Utility.gc();
Bitmap bmp = decodeFile(data);
Utility.gc();
// BitmapFactory.decodeByteArray(data, 0,
// data.length, o);
// Bitmap bmpCompressed = rotateBitmap(bmp, 90, 320, 430);
Bitmap bmpCompressed = Bitmap.createScaledBitmap(bmp, 430, 320,
true);
bmp.recycle();
Utility.gc();
writeBmp(bmpCompressed);
bmpCompressed.recycle();
Utility.gc();
} catch (Exception e) {
Log.e(Constants.TAG, e.getMessage(), e);
} finally {
isImageCapture = true;
}
}
};
private Bitmap decodeFile(byte[] buffer) {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new ByteArrayInputStream(buffer), null, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 70;
// 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(new ByteArrayInputStream(buffer),
null, o2);
}
how can i get rid from the above mention exception?

Use
Options.inSampleSize
// Decode image size
BitmapFactory.Options options = new BitmapFactory.Options();
//options.inJustDecodeBounds = true;
options.inSampleSize = 8;
BitmapFactory.decodeStream(new ByteArrayInputStream(buffer), null, options);

Take a look at this bug report:
http://code.google.com/p/android/issues/detail?id=8488
There's a known bug in Android relating to this error message, which doesn't seem to be accepted by Google. There are workarounds in the bug report if this is the problem you're having. I've used them to clear up similar issues.

You can try to do the scaling yourself using BitmapFactory.Options and BitmapFactory.decodeByteArray():
BitmapFactory.Options options = new BitmapFactory.Options;
options.inSampleSize = 4; // might try 8 also
BitmapFactory.decoderByteArray(data, 0, data.length, options);
There are also other options in BitmapFactory.Options to play around with.
You are probably running out of memory because you create a full decoded bitmap before you do the scaling.

Use less memory.
It definitely sounds like you have a memory leak somewhere if it works until the 10th picture is taken. Use the DDMS tools in Eclipse to track memory to try to see where it's happening.
