java.lang.NoSuchMethodError: No static method getFont(Landroid/content/Context;ILandroid/util/TypedValue;ILandroid/widget/TextView;)

Fix res/values/styles.xml and Manifest.xml like so:This solution is tested and don't forget to clean and build :

1.Manifest.xml

change the theme of HomeActivity to :

        <activity        android:name=".ui.home.HomeActivity"        android:theme="@style/Base.Theme.AppCompat.Light" />    <activity android:name=".BaseActivity"></activity>

2. res/values/styles.xmlMake all your themes preceeded with Base :styles.xml will be like this :

<resources><!-- Base application theme. --><!--<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">--><style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar"><!-- Customize your theme here. -->    <item name="colorPrimary">@color/colorPrimary</item>    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>    <item name="colorAccent">@color/colorAccent</item></style><style name="AppTheme.NoActionBar" parent="Base.Theme.AppCompat.Light">    <item name="windowActionBar">false</item>    <item name="windowNoTitle">true</item>    <item name="colorPrimary">@color/colorPrimary</item>    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>    <item name="colorAccent">@color/colorAccent</item></style><style name="AppTheme.AppBarOverlay" parent="Base.ThemeOverlay.AppCompat.Dark.ActionBar" /><style name="AppTheme.PopupOverlay" parent="Base.ThemeOverlay.AppCompat.Light" />

Detailed explanation as requested: Theme.AppCompat.Light.DarkActionBar is a subclass of the superclass Base anyway. Ctrl+click (Android Studio) on it and you will be taken to the source:

<style name="Theme.AppCompat.Light.DarkActionBar" parent="Base.Theme.AppCompat.Light.DarkActionBar" />

3. GithubBrowser-Master.gradle

make support_version = "27.0.0"and not support_version = "26.0.2

4.app.gradle :

compileSdkVersion 27    buildToolsVersion '27.0.0'

and not

   compileSdkVersion 26buildToolsVersion '26.0.2'

this is work for me:

    buildToolsVersion "27.0.3"

and

dependencies {compile 'com.android.support:appcompat-v7:27.0.0'compile 'com.android.support:design:27.0.0'compile 'com.android.support:support-v4:27.0.0'compile 'com.android.support:support-v13:27.0.0'}

In my case, I was using Android-KTX: implementation 'androidx.core:core-ktx:0.1' in Kotlin project, and that was the cause of the error. I just removed it from build.gradle as a dependency.
