alexandruc / android-bpg Goto Github PK

Hi,I need your help，I'm not good at clang, so I don't know what to do。
1.I test this library in my project, The vast majority of mobile phones can work. but I do monkey test on someone, it reports Native Crash.
2.I used https://github.com/nostra13/Android-Universal-Image-Loader and Customize my own Downloader（using bpg decoder https://github.com/nostra13/Android-Universal-Image-Loader/blob/master/sample/src/main/java/com/nostra13/universalimageloader/sample/ext/OkHttpImageDownloader.java )
3.I consulted a lot of information and test ，the crash line is this method(decoder.c-->bmp_save_to_buffer()-->free(rgb_line) ) , I find this https://groups.google.com/forum/#!topic/android-ndk/jQg6DM6-D6o

please help me , I don't know how to solve.

Wondering if this project is going to be maintained in the future.

I used your src file in android studio,Build success and run , But the image can't show all.

-----------use bpg_decoder get a bitmap:
public static Bitmap getDecodedBpgBitmap(Context context, File bpgFile) throws FileNotFoundException {
Bitmap bm = null;
try {
FileInputStream fis = new FileInputStream(bpgFile);
byte[] byteArray = toByteArray(fis);
byte[] decBuffer = null;
int decBufferSize = 0;
decBuffer = DecoderWrapper.decodeBuffer(byteArray, byteArray.length);
decBufferSize = decBuffer.length;

        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        options.inDither=false;

        if (decBuffer != null) {
           bm = BitmapFactory.decodeByteArray(decBuffer, 0, decBufferSize,options);
        }
    } catch (IOException ex) {
        TLog.e("getDecodedBpgBitmap", "Failed to convert image to byte array");
    }
    return bm;
}

--------------and save the bitmap to PNG ,but the transparent background became to black.
bpgBitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream)
