bitmap.getByteCount () method will return it's size. Here is the total bytes of bitmap in the memory: 12262248 Bytes, which equals to 12,3 MB. Yes, you might be confused. You may think that Image's.. incase people are wondering what Quality metric is. It is scale of 0 low to 100, high similar to photoshop export etc. As mentioned, its ignored for PNG, but you might wish to use CompressFormat.JPEG.As per google doco: Hint to the compressor, 0-100. 0 meaning compress for small size, 100 meaning compress for max quality.Some formats, like PNG which is lossless, will ignore the quality setting. 1. Determine bitmap size. The common misconception that I sometimes encounter is that the size of a bitmap in memory is the same or at least always related to the size of the file that you download from your server. So to optimize memory usage all we have to do is to make images that we fetch from the server smaller Getting bitmap from file path. So the thing is that i want to get Bitmap from absolute path, so i pass those paths as ArrayList<Strings> to my presenter, where i have next piece of code: private void decodeImageUri (final ArrayList<String> imageUris) { while (imageCounter < imageUris.size ()) { DecodeBitmapsThreadPool.post (new Runnable. To tell the decoder to subsample the image, loading a smaller version into memory, set inSampleSize to true in your BitmapFactory.Options object. For example, an image with resolution 2048x1536 that is decoded with an inSampleSize of 4 produces a bitmap of approximately 512x384

/** * Mass compression method * * @param image * @return */ public static Bitmap compressImage(Bitmap image) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); image.compress(Bitmap.CompressFormat.JPEG, 100, baos);//Quality compression method, here 100 means no compression, store the compressed data in the BIOS int options = 100; while. How to work with Bitmap in Android Android 02.08.2017. A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color There are a number of reasons why loading bitmaps in your Android app is tricky: Bitmaps can very easily exhaust an app's memory budget. For example, the camera on the Pixel phone takes photos of up to 4048x3036 pixels (12 megapixels). If the bitmap configuration used is ARGB_8888, the default for Android 2.3 (API level 9) and higher, loading a single photo into memory takes about 48MB of. Besides image type files, the Intent.ACTION_GET_CONTENT intent can be used to pick up any android documents with any file type extension.What you need to do is just invoke the Intent.ACTION_GET_CONTENT object's setType method and pass the file type extension string to it. For example, to select an android file of any document type, just pass */* to the intent object's setType method. AlarmClock; BlockedNumberContract; BlockedNumberContract.BlockedNumbers; Browser; CalendarContract; CalendarContract.Attendees; CalendarContract.CalendarAlert

Retrieve a file's MIME type. A file's data type indicates to the client app how it should handle the file's contents. To get the data type of a shared file given its content URI, the client app calls ContentResolver.getType (). This method returns the file's MIME type. By default, a FileProvider determines the file's MIME type from its filename. High end android devices can take great pictures. But great also means big, and sometimes you need them to have a limited width.Following snippet will get you that result. // we'll start with the original picture already open to a file File imgFileOrig = getPic(); //change getPic() for whatever you need to open the image file

fun reizeImageFileWithGlide (file: File, outputFile: File, size: Int) { // : Deferred<File> var bitmap = Glide.with(application) .asBitmap() .load(file) // .apply. ANDROID_BITMAP_FORMAT_RGBA_4444: Deprecated in API level 13. Because of the poor quality of this configuration, it is advised to use ARGB_8888 instead. ANDROID_BITMAP_FORMAT_RGBA_8888: Red: 8 bits, Green: 8 bits, Blue: 8 bits, Alpha: 8 bits. ANDROID_BITMAP_FORMAT_RGBA_F16: Each component is stored as a half float. ANDROID_BITMAP_FORMAT_RGB_56 Getting the real picture. This way is more painful, but don't worry, to get the full-sized image you need to ask the user to WRITE_EXTERNAL_STORAGE permission also. after that you need to create a fileProvider to android know where he can save the picture file, go to your Manifest and add this code bitmap using the Bitmap compression method. Check the file size without changing the quality of the bitmap image. 100 means the same quality. When you calculate the original image, result in 1.6 MB on the disk. Change the quality and check the file size again. I changed the quality to 50. And the result should be in 24.4 KB.Compress format. A bitmap is a mapping from one system such as integers to bits. It is also known as bitmap index or a bit array. The memory is divided into units for bitmap. These units may range from a few bytes to several kilobytes. Each memory unit is associated with a bit in the bitmap. If the unit is occupied, the bit is 1 and if it is empty, the bit is zero

You need to do this via some Graphic Applications like GIMP. As @Kevin Cooper told already, ideally you need to create different sets of resources (with different sizes) for different screen types

How to create small size image from original drawable bitmap image + decrease image size up to 50% in android. Image compression is very important feature for low speed internet connection devices because when application user usages 2G internet connection or slow WiFi then some times image loads slowly because of slow internet Lines 2 and 3 get the size of the device display. You use this as the target size for reducing the image size. In lines 4-7, you determine the size of the current bitmap. You do that by creating a BitmapFactory.Options class and setting the inJustDecodeBounds value to true. On line 6, the bitmap is decoded to get the dimensions The following is a proper method on how to save a bitmap to the Android file system. Even with the quality setting at 50, the images still look really good and in my experience take up about 10% of the size of a image saved with the quality set to 100. Next, we create a FileOutputStream which will be used to actually save the image..

RenderScript is an additional way to further improve the performance of your image processing. On devices that run Android 4.4 (API level 19) and higher, your app can interact with a documents provider, including external storage volumes and cloud-based storage, using the Storage Access Framework.This framework allows users to interact with a system picker to choose a documents provider and select specific documents and other files for your app to create, open, or modify

It will increase your APK file size, You can scale the bitmap to smaller size Currently, our library support image source types include File, byte array, file path and Bitmap. Support 2 image result types: Sometimes, when we got the compressed result, we have to process it later. In Android, we use Bitmap. In this circumstance, it's better to get Bitmap than File. So, to meet this requirement, we provided result type of.

  4. PNG or Portable Network Graphics is the most commonly used image file in Android these days. They provide a nice and high-resolution image format. But due to this, we need to apply some image compression techniques also. PNG compressions are lossless i.e. you can get back your original image from the compressed one i.e. no loss of color is there
  5. This gives you a bitmap with better compressed memory and quality. If you observe, we gave the quality as 90, usually this should result in higher in size of that image, still we get bitmap of less memory. Reason is, we compressed and taken out all the extra pixels of memory through handling of inSampleSize
  6. The Image and the bitmap are the same size: On iOS and Android, the Image is the pixel size of the bitmap. There is a one-to-one mapping between bitmap pixels and screen pixels. On Universal Windows Platform, the Image is the pixel size of the bitmap in device-independent units. On most devices, each bitmap pixel occupies multiple screen pixels
