#### But I did `setReplaceAll(true)`?! #### But I did `setReplaceAll(true)`?!
This won't change anything as `FileEmojiCompatConfig` will detect if the font file doesn't exist (or can't be read) and it will simply ignore `setReplaceAll(true)`. This won't change anything as `FileEmojiCompatConfig` will detect if the font file is not valid and it will simply ignore `setReplaceAll(true)`.
However, this is currently _not_ the case if something else goes wrong, e.g. if the file is not an EmojiCompat font. ## I want to let my users only choose another font if they don't like my current one
But even in this case only these flags are affected. This is easily possible with the introduction of `FileMojiCompat 1.0.6`.
In this case you override the fallback font by putting your font into the `assets` folder of your app using the name `NoEmojiCompat.ttf`.
Whenever the fallback font is needed (which is the case if the user doesn't specify another one), this font is being used.
In order to prevent blocking the `setReplaceAll` method, you'll have to call it with `setReplaceAll(true, true)`.
The second argument indicates that you want to ignore this `replaceAll`-prevention (if set to `true`. Setting it to `false` won't change anything).
So here's a short example of using this very flexible, yet easy to use method.
But please be aware that changing the emoji font using this snippet isn't very easy as it needs the user to copy (and potentially rename) some files:
```java
Context context = getContext();
File fontFile = new File(context.getExternalFilesDir(null), "emoji.ttf");
EmojiCompat.Config config = new FileEmojiCompatConfig(context, fontFile)
.setReplaceAll(true, true);
```
In this case, the font specified in `assets/NoEmojiCompat.ttf` will be used until `/storage/emulated/0/Android/[yourpackage]/files/emoji.ttf` exists and includes a valid `EmojiCompat` font.
This method combines the easy approach of `AssetEmojiCompatConfig` and the flexibility of `FileEmojiCompatConfig` with some tradeoffs on the usability side.
If you need a different asset path for your fallback file, you can simply add it as another argument when creating this font. This feature has been introduced in `1.0.7`.
**_PLEASE use at least this method in your app. It's always better to give the users a choice._**
