I have an Android Class Library Project that contains several font resources. This includes the following xml file (which is marked as an Android Resource)
<font-family xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
<font android:font="@font/arial" android:fontStyle="normal" android:fontWeight="400" app:font="@font/arial" app:fontStyle="normal" app:fontWeight="400"/>
<font android:font="@font/arialbd" android:fontStyle="normal" android:fontWeight="700" app:font="@font/arialbd" app:fontStyle="normal" app:fontWeight="700"/>
<font android:font="@font/ariali" android:fontStyle="italic" android:fontWeight="400" app:font="@font/ariali" app:fontStyle="italic" app:fontWeight="400"/>
<font android:font="@font/arialbi" android:fontStyle="italic" android:fontWeight="700" app:font="@font/arialbi" app:fontStyle="italic" app:fontWeight="700"/>
</font-family>
The font directory also includes ttf files for the files specified above. In one of my styles (which is also in the Android Class Library), I include the following:
<item name="android:fontFamily">@font/arialfamily</item>
In many places in my UI in the apps that reference this class library, I use this style for Button views. These Button(s) appear as desired in the designer as well as when I debug the app on my Surface Duo or the emulator, but when I debug it on my Samsung Galaxy S10e, the text does not appear correctly (it is the same text, but it is definitely a different font). I think the font is not being copied when I debug the app, but I am not sure what I am doing wrong. What can I do to insure that the font is copied when I build the app?

Hi, njsokalski. If this only occurs on the specified device, the problem may be caused by the device. You could test on different devices with the same build version or another Samsung device to check that. If so, it's suggested to reported the issue to the portal of the manufacturer for a solution.
I am somewhat confused by what you are suggesting. If the problem is "caused by the device", does that mean I cannot force my app to use a specific font even if I do include the *.ttf file? I do not understand the purpose of custom fonts if I cannot force the app to use them on all devices. I find it hard to believe that there is no way to control the font used by app (or at least by a specific View). Also, even if I did "test on different devices", I would still need to figure out how to make it work on this device, because it is a device, so there may be people using it.
The manufacturer may customize the setting of the device which will cause some function code doesn't work or it may need some extra operations. If the code works fine on some devices with the same framework, it means there is nothing wrong with the code. The problem is due to the device itself.

Does that mean I can never make it work on certain devices?
it may need some extra operations
If this is the case, what are those extra operations, or where can I find it? If the manufacturer is able to do this kind of customization, it sounds like a lot of device-specific code.

I think Android is trying to automatically choose the best font, and is therefore causing my font specification to be useless. For example, when I tried using some of the non-standard characters, it did not change the font, and when I tried using a font containing primarily symbols, it did not change it. I think it is trying to say it thinks that it can find a better font than the one I tell it to use. Is there a way to disable automatic font selection?
Is there a way to disable automatic font selection
This function cannot be achieved in code. Try to search the function on your test device to disable it.
It sounds like some (almost) Android devices don't want to let you use all the features of the Android OS, so for now I am going to resort to drawing the 1 character in which it is required for my app's appearance using a drawable; luckily it is just a simple multiplication character (just a rotated +). Thank you for your help in learning what can & can't be done with fonts.
