outofmemory exception for Large Bitmap

I found a lot of documentation on how to load large Bitmaps and avoid outofmemory exception. but the problem is that I have to take the image from my MediaStore.Images.media so the classical
decodeFile(path,options) indicated in the google documentation does not work to me
As you can see below I decommented the line // Bitmap photo= Mediastore.Images, that is the one that triggers the out of memory. on the other side adding
the line Bitmap bm=BitmapFactory.decodeFile(selectedImageToUri,options) returns null, although the compiler can see both the path in selectedImageToUri (that indicates the content provider where the pics are) than the options value, that I set to 8, because I want to subscale all the images
My question is how can I insert in bm the bitmap that is referring to the image selected by the user in the gallery. in the line BitMap photo does not return null and work really well, but I decommented because after I change a couple of images gives me outofmemory exception.
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable final Bundle savedInstanceState) {
if (flagVariable) {
if (selectedImageToUri != null) {
// BitMap photo = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), Uri.parse(selectedImageToUri));
final BitmapFactory.Options options= new BitmapFactory.Options();
options.inSampleSize=8;
Bitmap bm = BitmapFactory.decodeFile(selectedImageToUri, options);
pic = new BitmapDrawable(bm);
getActivity().getWindow().setBackgroundDrawable(pic);
} else {
getDefaultImageBackground(inflater, container);
}
hiddenList = inflater.inflate(R.layout.fragment_as_list_layout_temp, container, false);
} else {
getDefaultImageBackground(inflater, container);
}
listView = (ListView) hiddenList.findViewById(R.id.list_hidden);

MediaStore.getBitmap is just a simple convienence method, it looks like this:
public static final Bitmap getBitmap(ContentResolver cr, Uri url)
throws FileNotFoundException, IOException {
InputStream input = cr.openInputStream(url);
Bitmap bitmap = BitmapFactory.decodeStream(input);
input.close();
return bitmap;
}
You can create your own method based on this that takes the options and calls a different overload on BitmapFactory:
public static final Bitmap getBitmap(ContentResolver cr,
Uri url,
BitmapFactory.Options options)
throws FileNotFoundException, IOException {
InputStream input = cr.openInputStream(url);
Bitmap bitmap = BitmapFactory.decodeStream(input, null, options);
input.close();
return bitmap;
}
Usage:
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap bm = getBitmap(getActivity().getContentResolver(),
Uri.parse(selectedImageToUri),
options);

I spent a lot of time on this problem, but no one will give me exact answer and finally i solved it. First create method and provide Image URI as argument, and this will return bitmap basically here i calculated image size on bases of, we can manage memory as well as image and get exact image in bitmap form.
you can even display 5000×8000 and 12MiB picture without any error code is tested just copy paste in your class and enjoy.
Use
Bitmap mBitmap = getPhoto(MYIMAGEURI);
Provide URI to method and get Bitmap
Bitmap getPhoto(Uri selectedImage) {
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int width = metrics.widthPixels;
Bitmap photoBitmap = null;
InputStream inputStream = null;
try {
inputStream = getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmapOptions.inJustDecodeBounds = true;
BitmapFactory.decodeStream(inputStream, null, bitmapOptions);
int imageWidth = bitmapOptions.outWidth;
int imageHeight = bitmapOptions.outHeight;
#SuppressWarnings("unused")
InputStream is = null;
try {
is = getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
float scale = 1.0f;
if (imageWidth < imageHeight) {
if (imageHeight > width * 1.0f) {
scale = width * 1.0f / (imageHeight * 1.0f);
}
} else {
if (imageWidth > width * 1.0f) {
scale = width * 1.0f / (imageWidth * 1.0f);
}
}
photoBitmap = decodeSampledBitmapFromResource(this,
selectedImage, (int) (imageWidth * scale),
(int) (imageHeight * scale));
return photoBitmap;
}
Decode Bitmap Sample using image size
public static Bitmap decodeSampledBitmapFromResource(Context context,
Uri uri, int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
InputStream is = null;
try {
is = context.getContentResolver().openInputStream(uri);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
BitmapFactory.decodeStream(is, null, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth,
reqHeight);
// Decode editBitmap with inSampleSize set
options.inJustDecodeBounds = false;
InputStream inputs = null;
try {
inputs = context.getContentResolver().openInputStream(uri);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return BitmapFactory.decodeStream(inputs, null, options);
}
Calculate Sample Size
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) {
// Calculate ratios of height and width to requested height and
// width
final int heightRatio = Math.round((float) height
/ (float) reqHeight);
final int widthRatio = Math.round((float) width / (float) reqWidth);
// Choose the smallest ratio as inSampleSize value, this will
// guarantee
// a final image with both dimensions larger than or equal to the
// requested height and width.
inSampleSize = Math.min(heightRatio, widthRatio);
// inSampleSize = heightRatio < widthRatio ? heightRatio :
// widthRatio;
}
return inSampleSize;
}
Or may be possible to solved using one line of code in manifiest.xml
is in application tag use this
android:largeHeap="true"

Image shown when taken by front camera but not visible when taken by Back camera

I am using native camera in my app. And after taking picture I am showing it to user on next activity in the Imageview. Now the problem is, when I save picture taken by front camera, the picture shows up in the next activity's imageview but not in the case when taken by back camera.
I am going to next activity after taking picture in the following way:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
case REQUEST_CODE_HIGH_QUALITY_IMAGE:
Toast.makeText(getApplicationContext(),
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://"
+ Environment.getExternalStorageDirectory())));
//refreshing gallery
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(mHighQualityImageUri);
sendBroadcast(mediaScanIntent);
Intent intentActivity = new Intent(MyCameraActivity.this,PhotoSortrActivity.class);
intentActivity.putExtra("data", mHighQualityImageUri);
Log.v("Uri before Sending",mHighQualityImageUri+"");
startActivity(intentActivity);
break;

}
and this where I am showing the captured image. :

}
}
Usage of method
Bitmap bmp = ImageResizer.decodeSampledBitmapFromFile(new File(filePath).getAbsolutePath(), 512, 342);
This will resize your bitmap so that you can get rid from OOM error.process these inside UI thread which seems better.

Bitmap myBitmap = BitmapFactory.decodeFile(mediaFile.getAbsolutePath());
int height = (myBitmap.getHeight() * 512 / myBitmap.getWidth());
Bitmap scale = Bitmap.createScaledBitmap(myBitmap, 512, height, true);
// Here mediaFile is path of image.
// display scale bitmap to your ImageView

Sampling a bitmap from url

I am trying to reduce the size of bitmap from a url. I saw many posts, but all were about sampling a local file. I want to sample the image at url. Here is my code:
public Bitmap getScaledFromUrl(String url) {
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 1 / 10;
try {
return BitmapFactory.decodeStream((InputStream) new URL(url)
.getContent());
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
Is this approach correct? I am getting out of memory crashes in my app at this function. Any ideas?

This works. I found it at http://blog.vandzi.com/2013/01/get-scaled-image-from-url-in-android.html . Use the following snippet of code, pass params as you like.
private static Bitmap getScaledBitmapFromUrl(String imageUrl, int requiredWidth, int requiredHeight) throws IOException {
URL url = new URL(imageUrl);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeStream(url.openConnection().getInputStream(), null, options);
options.inSampleSize = calculateInSampleSize(options, requiredWidth, requiredHeight);
options.inJustDecodeBounds = false;
//don't use same inputstream object as in decodestream above. It will not work because
//decode stream edit input stream. So if you create
//InputStream is =url.openConnection().getInputStream(); and you use this in decodeStream
//above and bellow it will not work!
Bitmap bm = BitmapFactory.decodeStream(url.openConnection().getInputStream(), null, options);
return bm;
}
private 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;
}
It's really flexible.. I think you should try it out.

You are using it wrong. You are asking to make the picture 10 times bigger :) You should give the command in normal numbers, not fraction. For example:
final BitmapFactory.Options options2 = new BitmapFactory.Options();
options2.inSampleSize = 8;
b = BitmapFactory.decodeFile(image, options2);
with this configuration you obtain 8 times smaller picture than the original.
UPDATE: To load image from internet add this class to the project and do the following:
ImageLoader loader = new ImageLoader(context);
Bitmap image = loader.getBitmap(URL);

Load large bitmap from url and resize it

I want load huge image from url and show on my device. I read this post for doing this.
In that example they use native drawable but I want get image from server.
I am using this code
private void getBitmap(ImageView imageView,final String url){
mBitmapOptions = new BitmapFactory.Options();
mBitmapOptions.inJustDecodeBounds = true;
URL mUrl = null;
InputStream is= null;
try {
mUrl = new URL(url);
is = mUrl.openStream();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// BitmapFactory.decodeStream(is,null,mBitmapOptions);
mCurrentBitmap = Bitmap.createBitmap(mBitmapOptions.outWidth,
mBitmapOptions.outHeight, Bitmap.Config.ARGB_8888);
mBitmapOptions.inJustDecodeBounds = false;
mBitmapOptions.inBitmap = mCurrentBitmap;
mBitmapOptions.inSampleSize = 1;
BitmapFactory.decodeStream(is,null,mBitmapOptions);
imageView.setImageBitmap(mCurrentBitmap);
// Bitmap croppedBitmap=Bitmap.createBitmap(Bitmap.createBitmap(mCurrentBitmap, 0, mCurrentBitmap.getHeight()/2, mCurrentBitmap.getWidth(), mCurrentBitmap.getHeight()/2));
// imageView.setImageBitmap(croppedBitmap);
}
I want here get image from url and resize it but I have an exception.
java.lang.IllegalArgumentException: width and height must be > 0
What I did wrong here? or could you suggest me better answer?

I would use Picasso, then what you want to achieve is as simple as this:
Picasso.with(context).load(url).resize(50, 50).into(imageView)
http://square.github.io/picasso/

You get the exception because of:
// BitmapFactory.decodeStream(is,null,mBitmapOptions);
There are no mBitmapOptions set when you try to call:
mCurrentBitmap = Bitmap.createBitmap(mBitmapOptions.outWidth, mBitmapOptions.outHeight, Bitmap.Config.ARGB_8888);
Have a look at the answer in this question to further optimize your code: Getting the size of an image inputstream

I developped a solution based on http://developer.android.com/training/displaying-bitmaps/load-bitmap.html tutorial. Here is my code. The tricky part consist of using a byte array to store image data (because unfortunatly markSupported() is not available for connection.getInputStream()).
public static Bitmap getBitmapFromURL(final String imageUrl, final Options options, int reqWidth, int reqHeight) {
try {
URL url = new URL(imageUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
final InputStream input = connection.getInputStream();
// using byte array to prevent open 2 times a stream
final BufferedInputStream bis = new BufferedInputStream(input, 4*1024);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte)current);
}
bis.close();
byte[] imageData = baf.toByteArray();
if(options != null){
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options optionsSize = new BitmapFactory.Options();
optionsSize.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(imageData, 0, imageData.length, optionsSize);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(optionsSize, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
optionsSize.inJustDecodeBounds = false;
}
Bitmap myBitmap = null;
if(options == null){
myBitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length);
}
else{
myBitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
}
// close the stream;
input.close();
return myBitmap;
} catch (Exception e) {
return null;
}
}
private 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) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
Hope it will helps you.

large bitmap crushes (out of memory)

I am following developer.android website here and I am trying load large image from url (i.e 1024 x 900) My code works fine in my Google Nexus but doesn't work on Nexus s.

BufferedInputStream bis = new BufferedInputStream(is, 4*1024);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {

}
}
}
}
When I run on Nexus s I have out of memory exception. As following android developer website I didn't understand what I did wrong here and why my application crushes in old devices.
Please help.
Note: my image width should be match_parent always. That's why I put calculateInSampleSize(option,1024,128)

You are wasting memory becuase you've set inJustDecodeBounds after you decoded the whole image once. (I guess you get OOM because of that later on). Consider closing your inputstream as well.
BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
options.inJustDecodeBounds = true;
options.inSampleSize = calculateInSampleSize(options, 1024, 128);
options.inJustDecodeBounds = false;
Bitmap bitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length,options);
return bitmap;
I think you really meant to do:
options.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options);
options.inSampleSize = calculateInSampleSize(options, 1024, 128);
options.inJustDecodeBounds = false;
Bitmap bitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length,options);
return bitmap;
That will get the width and height of the image without storing the bitmap (just get options) and then you subsample the image to correct size after that and returns the bitmap.
I don't understand why you resize the bitmap again in onPostExexute of your asynctask, imageView.setImageBitmap(Bitmap.createBitmap(bitmap, 0, bitmap.getHeight()/2, bitmap.getWidth(), bitmap.getHeight()/2));
When you just completed to load the bitmap, why not load the correct size to begin with? (after doing the above changes i would suggest you to log the sizes and see if you really need to resize again in onPostExexute)
Have you looked at image loading libraries?
There's quite a few available, one that seems to fit your needs is Picasso
Where one can do such things as: Picasso.with(context).load("url_to_image").fit().into(imageView);
This downloads and caches the bitmap (in a background thread) and fits and draws into an imageView, all in one line, neat!

You must do the Bitmap extraction in Thread not in Main thread , Do this within a AsyncTask Otherwise your app will get out of memory.
Do the work in your getBitmapFromURL() work within doInBackground method of Asynctask

In your manifest : add android:largeHeap=true to your application tab.
