If the bitmap's internal config is in one of the public formats, return that config, otherwise return null.

Usage

From source file:Main.java

    try {/*  w w  w . ja  v  a  2 s  .c o m*/
        // this is the file going to use temporally to save the bytes.

        srcBitmap.copyPixelsToBuffer(map);
        // recycle the source bitmap, this will be no longer used.
        srcBitmap.recycle();
        System.gc();// try to force the bytes from the imgIn to be released

        // Create a new bitmap to load the bitmap again. Probably the memory
        // will be available.
        srcBitmap = Bitmap.createBitmap(width, height, type);
        map.position(0);
        // load it back from temporary
        srcBitmap.copyPixelsFromBuffer(map);
        // close the temporary file and channel , then delete that also
        channel.close();
