java.lang.NoSuchMethodException: addFontWeightStyle Error

Question

I am getting an exception which is thrown when I set the contentView of the MainActivity to the XML below. It already worked fine, but after some hours of implementation on other Activities I am getting this error. I cant reproduce the cause of this error. Maybe a change of min SDK Version or the implementation of a new library.

I am using the following libraries:

implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0-alpha1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.2-alpha01'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.2-alpha01'
    implementation 'androidx.cardview:cardview:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha01'
    implementation 'com.google.android.material:material:1.0.0-beta01'
    implementation 'me.gujun.android.taggroup:library:1.4@aar'
    implementation 'com.squareup.okhttp3:okhttp:3.2.0'
    implementation 'com.aurelhubert:ahbottomnavigation:2.3.4'
    implementation 'com.github.feeeei:CircleSeekbar:v1.1.2'

    implementation 'com.github.igalata:Bubble-Picker:v0.2.4'
    implementation 'com.ogaclejapan.arclayout:library:1.1.0@aar'

Answer 1

In the app gradle file,

Replace:

implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'

with:

implementation 'androidx.appcompat:appcompat:1.0.2'

Answer 2

The issue is already tracked here: https://issuetracker.google.com/issues/124274577

This has already been solved by https://android-review.googlesource.com/c/platform/frameworks/support/+/878553/ and is going to be available in a future release. Currently the exception is thrown but it doesn't affect the app (the typeface still loads correctly), everything should still work fine.

You can wait for a future release of AppCompat, go back to an older stable release or continue using this release for testing if it doesn't crash.
