java - App crashing after selecting photo from gallery

Question

I created an image processing app which shows percentage of similarity between images using openCV. However, whenever I select an image the application process crashes.

Here is the logcat:

E/HW-JPEG-DEC: [HME_JPEG_DEC_Delete](3321): HME_JPEG_DEC_Delete: decoder_ctx=null

and here is the line in mainactivity 161

toMatch[4] = BitmapFactory.decodeResource(getResources(), R.drawable.cleaf5);

Answer 1

Your file is too big. Add try-catch block and try to load smaller images with options.inSampleSize (try different values for options.inSampleSize)

Example:

Bitmap bitmap = null;

try{
bitmap =  BitmapFactory.decodeResource(getResources(), R.drawable.cleaf5, options);
}catch(OutOfMemoryError e)    
   try{
   BitmapFactory.Options options = new BitmapFactory.Options();
   options.inSampleSize = 8;
   bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.cleaf5, options);
   }catch(OutOfMemoryError e) {}
}

if(bitmap != null){
//do smth
}
