i need set the small Android notification icon through PNG from a external URL instead of using mipmap.
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
notificationBuilder.setSmallIcon(R.mipmap.ic_notification);
notificationBuilder.setColor(ContextCompat.getColor(getApplicationContext(), android.R.color.transparent));
}
Need to pass a external PNG image instead of using: R.mipmap.ic_notification
Does anyone know if it is possible?
If you read the developer documents specific to Notification.Builder you will see that setSmallIcon(int icon) needs a A resource ID in the application's package of the drawable to use.
Downloading an image, converting to a bitmap and then setting it to the setSmallIcon(int resId) is still going to give you an error.
Even if you were to convert the Bitmap to a Drawable like this for instance:
Drawable d = new BitmapDrawable(getResources(), bmpFinal);
it is still going to give you an error because that Drawable does not exist in your application package.
The only possible solution is to use a Drawable resource that exists in your package and set it to the setSmallIcon() method. Typical usage:
builder.setSmallIcon(R.drawable.ic_launcher);
Alternatively, the setLargeIcon (Bitmap icon) requires a Bitmap instance. Without having to make any additional changes in your current code (since you already have a Bitmap), you can use that as it is, if it fits your requirement.
If not, you pretty much have to use a Drawable resource that is already present in one of the drawable folders.
