can't get rid of exception "Caused by: java.lang.AbstractMethodError: abstract method "android.graphics.Typeface com.mikepenz.iconics.typeface.ITypeface.getRawTypeface()""

[jrm0695]

I don't manage to have the librairy work despite several hours of research. Whatever version I use, it always end up with this exception when I use .build method :

Caused by: java.lang.AbstractMethodError: abstract method "android.graphics.Typeface com.mikepenz.iconics.typeface.ITypeface.getRawTypeface()"

I'm using a project in java. I implemented lastest version of the librairy, as proposed by Android Studio :

implementation "com.mikepenz:iconics-core:5.0.2"; implementation 'com.mikepenz:material-design-iconic-typeface:2.2.0.5@aar'` Here is how I use it : new Iconics.Builder().style(new ForegroundColorSpan(colorText)).on(myButton).build();

myButton is an AppCompatButton. Here is my implementation of AppCompat :

implementation 'androidx.appcompat:appcompat:1.3.0-alpha02' Has anyone any idea ? I checked that I wasn't alone having this issue but I didn't understand very well the answers (is it a problem with my typeface version 2.2.0.5 that isn't compatible with the core v5.0.2 ? )

Thank you

@jrm0695 you have to use fonts with the -kotlin suffix with iconics v5

https://github.com/mikepenz/Android-Iconics#2-choose-your-desired-fonts

[mikepenz]

So

implementation 'com.mikepenz:material-design-iconic-typeface:2.2.0.6-kotlin@aar'

should work for you. 2.2..0.7 will require iconics 5.1.0

Hey @mikepenz thank you so much for your reactivity. After I read the readme, it is said for androidx users, version is 3.2.5. So I modified to :

    implementation "com.mikepenz:iconics-core:3.2.5" 
    implementation "com.mikepenz:iconics-views:3.2.5"
    implementation 'com.mikepenz:material-design-iconic-typeface:2.2.0.6-kotlin@aar'`

After I do that, I created a button like this :

    <androidx.appcompat.widget.AppCompatButton
        android:id="@+id/button_0"
        android:layout_width="wrap_content"
        android:text="{gmi_done} HELLO"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent" />

and I wrote this to try to make it work in the main activity :

Iconics.init(this);
button = findViewById(R.id.button_0);
new Iconics.IconicsBuilder().style(new ForegroundColorSpan(0xffff0000)).on(button).build();

But the button displays "{gmi_done} HELLO" so it doesn't work :/

[mikepenz]

for v3 of the library you have to use the old font, which you had before :)

the font addons have to match the iconics version

Just see the versions at that state herE: https://github.com/mikepenz/Android-Iconics/tree/v3.2.5

[jrm0695]

Thanks for your answer, I'm new to github, didn't know I could switch btw versions :) So, unfortunately, I used the right font version for core version 3.2.5 :

    implementation "com.mikepenz:iconics-core:3.2.5"
    implementation "com.mikepenz:iconics-views:3.2.5"
    implementation 'com.mikepenz:material-design-iconic-typeface:2.2.0.5@aar'

which is what is recommanded in the link, but now when I do :

AppCompatButton button ;
button = findViewById(R.id.button_0);
new Iconics.IconicsBuilder().style(new ForegroundColorSpan(0xffff0000)).on(button).build();

I have a new exception coming :

"Attempt to invoke virtual method 'int android.graphics.Typeface.getStyle()' on a null object reference"

Maybe the 3.2.5 is too old and I should go to version 5 instead ? I have to admit I have no idea what to do ...

EDIT : tried version 4.0.2 this one works with the recommended fonts 👍
