View 2 Replies Similar Messages: Android :: BitmapFactory.decodeStream Returns Null Android :: BitmapFactory.decodeStream Returns Null. why is BitmapFactory.decodeFile returning null? I can verify that the file is getting saved correctly as I can pull it using adb and see the png displaying properly. Further in my code I try to use de BitmapFactory.decodeByteArray(myImage, 0, myImage.lenght) but the Bitmap that it returns me is always null Does someone have an idea ?

Hi Sir I have Problem is that if i change image on firebase through direct or other one upload his new image then when i load this image than its show old image and get from catch memory so please tell me how to notify to catch if i change image on firebase is it because of replace image ? AssetManager.open() returns InputStream that is used with BitmapFactory.decodeStream() that returns Bitmap which is used with imageView.setImageBitmap(). AssetManager.list() To list all the assets for the given folder within /assets folder, we use AssetManager.list().Suppose we have some files within /assets/img and we need to list all those files, then we write code as follows. So we are using bitmap’s method with AssetManager including input stream to call image file directly from Assets folder and set into ImageView . So here is the complete step by step tutorial for Show/Load image inside ImageView from assets folder in android I would like to also post a best practices answer for those looking to do this (but may be asking the wrong question). Instead of passing a bitmap around (which I presume you downloaded from the network, otherwise, you would already have a file reference to it), I recommend using an image loader such as Universal Image Loader to download an image into an ImageView.
String text = "This is sample text file"; String name = "sampleText.txt"; StorageObject storageObject = new StorageObject(null, text.getBytes(), "text/plain"); storageObject.setDisplayName(name);
In this article, we will create an Android application which will download XML data from a remote http server. Then it will parse the downloaded xml data a Found a method somewhere that did the trick: public static Bitmap getScreenViewBitmap(View v) { v.setDrawingCacheEnabled(true); // this is the important code :) // Without it the view will have a dimension of 0,0 and the bitmap will be null… Note that this is a bit contrived for learning purposes. Calling our blur code three times is less efficient than having BlurWorker take in an input that controls the "level" of blur. Android bitmap rotate I'm having issues with BitmapFactory.decodeStream(inputStream).When using it without options, it will return an image.
