问题:

When I create my app and lauch it from my IDE (Eclipse) app is working great, but when I build APK, it's crashing, but I can't figure out why? It shows Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1). I uses https://github.com/puelocesar/android-lib-magick library in my app.

Thanks in Advance..

This is my code

protected Void doInBackground(Void... params) {

                              try{
                                ImageInfo info=new ImageInfo(selectedImagePath);
                                MagickImage imageCMYK = new MagickImage(info);


                            if(imageCMYK.getColorspace()==12){
                                  bitmap=getCMYKImageFromPath(selectedImagePath);

                            }
                            else {
                                  //do something

                                }
                            }
                            }catch (Exception e) {
                                e.printStackTrace();
                            }
                            return null;




                        }

This is the code which retrieves the image

  public Bitmap getCMYKImageFromPath(String path) {

                            try {
                                ImageInfo info = new ImageInfo(path); // where the CMYK image is
                                MagickImage imageCMYK = new MagickImage(info);

                                Log.d("DEBUG", "ColorSpace BEFORE => " + imageCMYK.getColorspace());
                                boolean status = imageCMYK.transformRgbImage(ColorspaceType.CMYKColorspace);
                                Log.d("DEBUG", "ColorSpace AFTER => " + imageCMYK.getColorspace() + ", success = " + status);

                                bitmap = MagickBitmap.ToBitmap(imageCMYK);
                            } catch (Exception e) {
                                e.printStackTrace();
                            }
                            return bitmap;
                        }

If the native library is using reflection to call back into the Java code, you need to preserve the called classes, fields, and methods. Otherwise, ProGuard may rename or even remove them, leading to a confusing crash in the native code. Without knowing the internals of the library, you could preserve all of its classes, fields, and methods:

-keep class magick.** { *; }
-keep class fakeawt.** { *; }

If this helps, you could try narrowing these options down to keep the minimal number of classes, fields, and methods.
