android - BitmapFactory.decodeStream(is) fails on some image in Download folder -

i'm using phonegap 2.5.0 , here how call method:

try {         inputstream = cordova.getactivity().getcontentresolver()                 .openinputstream(uri.parse(inputstring));         bitmap bmp = bitmapfactory.decodestream(is);         is.close(); 

the code works fine when take photo using camera randomly fails on images download folder. checked images, downloaded locally url content://media/external/images/media/xxxx. files pretty large 6mb while others small 700k. failure seems random returning null , not caught exception.

any chance it's jpeg?

see known issue:-

https://code.google.com/p/android/issues/detail?id=6066

i use following decoding bitmaps:-

bitmapfactory.decodestream(new flushedinputstream(is), null, opts);  public class flushedinputstream extends filterinputstream { public flushedinputstream(inputstream inputstream) {     super(inputstream); }  @override public long skip(long n) throws ioexception {     long totalbytesskipped = 0l;     while (totalbytesskipped < n) {         long bytesskipped = in.skip(n - totalbytesskipped);         if (bytesskipped == 0l) {               int mybyte = read();               if (mybyte < 0) {                   break;  // reached eof               } else {                   bytesskipped = 1; // read 1 byte               }        }         totalbytesskipped += bytesskipped;     }     return totalbytesskipped; } } 

also, if of images large, may want set sample size don't cause large allocation.

bitmapfactory.options opts = new bitmapfactory.options(); opts.insamplesize = samplesize; 

where samplesize sensible value you've calculated.
