内存不足，Android 5中的图像

Question

My app loading lot of images from network and decode it via BitmapFactory.decodeByteArray . But when the application is decoded many images throws error java.lang.OutOfMemoryError . So before i set flag inPurgeable = true in BitmapFactory.Options and this error will never not bother me.

In Android 5 field BitmapFactory.Options.inPurgeable is deprecated and java.lang.OutOfMemoryError is thrown again after decoding a large amount of images.

What I should use in Android 5 to avoid this error?

EDIT:

My code:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPurgeable = true;
bitmap = BitmapFactory.decodeByteArray(buffer.toByteArray(), 0, buffer.length(), options);

It all. This works fine on Android 4 or less.
