Canvas: trying to use a recycled bitmap android.graphics.Bitmap in Android

Question

I am working on the crop image class, but encounter a recycled bit map problem:

03-02 23:14:10.514: E/AndroidRuntime(16736): FATAL EXCEPTION: Thread-1470
03-         


        

Answer 1

For those that did not find a solution so far. I had the same problem. I tried to recycle a bitmap in onPause like this:

final Drawable drawable = mImageView.getDrawable();
if (drawable instanceof BitmapDrawable) {
    BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
    Bitmap bitmap = bitmapDrawable.getBitmap();
    bitmap.recycle();
}

if (preView != null && !preView.isRecycled()) {
    preView.recycle();
    preView = null;
}

After returning back i got the exception: "Canvas: trying to use a recycled bitmap"

Solution for me: I had to add the following

mImageView.setImageBitmap(null);
