Checking if bitmap is recycled doesn't help to solve "RuntimeException: Canvas: trying to use a recycled bitmap"

I send bitmaps to my activity from Service (using LocalBroadcastManager and intent bitmap extra)

I set them to ImageView in activity like this:

if (!bitmap.isRecycled) {
    imageView.setImageBitmap(bitmap)
}

When I don't need the service anymore I close it and release bitmap object kept in that service

But when I close the service I usually get the following error:

java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@fc4b896

Sobitmap.isRecycled condition doesn't help here

Is there any safe method to set Bitmap to ImageView?

When you are using imageView.setImageBitmap(bitmap), you should not recycle the bitmap after setImageBitmap because your imageView is still referencing and using that bitmap. You can recycle it when activity/fragment/view is destroyed.

You exception is telling you that bitmap is already recycled so no need to app check

java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@fc4b896

instead just check for null value

Also check documentation why you got an error

https://developer.android.com/reference/android/graphics/Bitmap#isRecycled()
