question: public static Bitmap loadBitmapWithBackouts ( Context context , Uri sourceUri , int sampleSize ) { boolean noBitmap = true ; int num_tries = 0 ; if ( sampleSize <= 0 ) { sampleSize = 1 ; } Bitmap bmap = null ; while ( noBitmap ) { try { bmap = loadDownsampledBitmap ( context , sourceUri , sampleSize ) ; noBitmap = false ; } catch ( java . lang . OutOfMemoryError e ) { if ( ++ num_tries >= BITMAP_LOAD_BACKOUT_ATTEMPTS ) { throw e ; } bmap = null ; System . gc ( ) ; sampleSize *= 2 ; } } return bmap ; }
target:  Loads a bitmap that is downsampled by at least the input sample size. In low-memory situations, the bitmap may be downsampled further.
