Android ChipGroup IllegalArgumentException, even though using MaterialComponents theme

I'm using a com.google.android.material.chip.ChipGroup in an AppCompatActivity, but when I try to make a Chip, I'm getting java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).. I have tried every possible Theme.MaterialComponents theme (yes, even .Bridge), and I'm still getting the error. Somewhere else in the app, I'm also using a chipgroup and making new chips, and everything works fine. What am I missing here?

Relevant in MyActivity:

Chip chip = new Chip(getApplicationContext());

Relevant in MyActivity xml:

<com.google.android.material.chip.ChipGroup
    android:id="@+id/filter_chips"
    android:layout_width="0dp"
    android:layout_height="wrap_content"/>

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.appname">
    <uses-permission android:name="android.permission.INTERNET" />
    <application

        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:networkSecurityConfig="@xml/network_security_config"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppName">
        <activity android:name=".MainActivity">
            <intent-filter>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="MyActivity"/>

            android:name="org.apache.http.legacy"
            android:required="false" />
    </application>
</manifest>

        <item name="android:statusBarColor" tools:targetApi="l">?

    </style>
</resources>

Don't use application context, use the activity's context. Application context does not have material theme enabled in it.
