Android内存不足错误

Question

In my Activity, i'm trying to do a bit of image processing of my own. I have algorithms that manipulate the image the way I want to, which is the object LabAware. I have noticed that when I comment out the last 3 lines of codes, i don't get a Out of Memory Error. Also, I pass an Bitmap in my algorithm, where I do image processing and accessing of pixels. I also added the android:largeHeap = "true; statement in my manifest file. How do I tackle the Out of Memory Error?

Drawable drawable = getResources().getDrawable(R.drawable.test);
Bitmap image = ((BitmapDrawable) drawable).getBitmap();
Bitmap imageTwo = image.createBitmap(900,1200, Bitmap.Config.ARGB_8888);
grayImage = Bitmap.createScaledBitmap(image,900,1200,false);
//grayImage is a public member variable of the activity

LabAware  lab = new LabAware();
lab.calculateChip(grayImage,852 ,420);
printInt(lab.green1);

You can try using android:largeHeap="true" . If that only delays the crash, you probably have a memory leak. The allocation that triggers the crash usually has nothing to do with the problem, so the stack trace will be useless. You need to dump the heap and look for objects that shouldn't be there. Find out what's holding a reference to them, then study your code to find out why.
