Formats supported by BitmapFactory.decodeByteArray(…)
Yes, it's reasonable to assume (a bit more so if you take a peek at the source code of AOSP). The JNI native methods for BitmapFactory are in BitmapFactory.cpp. https://github.com/android/platform_frameworks_base/blob/master/core/jni/android/graphics/BitmapFactory.cpp Since both BitmapFactory.decodeByteArray() and the BitmapDrawable(InputStream) constructor end up calling doDecode(), and since this constructor is used when loading resources...

bitmap size exceeds VM budget in some devices
android,android-drawable,android-image,android-bitmap
1. For dealing with Bitmap objects: BitmapFactory.Options options=new BitmapFactory.Options(); options.inSampleSize = 8; options.inDither = false; options.inPurgeable = true; options.inInputShareable = true; Bitmap bitmap = BitmapFactory.decodeStream(is, null, options); Also, you need to use bitmap.recycle(); before you make your Bitmap instances null. This will help save memory. 2. For dealing with images...

How to zip multiple images and post to server using google recommended HTTPURLConnection? [closed]
