问题描述

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.
这是logcat:

这是主要活动161中的行
and here is the line in mainactivity 161
toMatch[4] = BitmapFactory.decodeResource(getResources(), R.drawable.cleaf5);
推荐答案
您的文件太大. 添加try-catch块并尝试使用options.inSampleSize加载较小的图像(为options.inSampleSize尝试不同的值)
Your file is too big. Add try-catch block and try to load smaller images with options.inSampleSize (try different values for options.inSampleSize)
示例:
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
}
