Question

当每个人都在谈论alpha3到alpha1并且我得到beta01时，有人遇到同样的问题吗？

    dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0-beta01'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

好吧，我刚刚通过覆盖现有的方法解决了这个问题。

implementation 'com.android.support:appcompat-v7:28.0.0-beta01'
implementation 'com.android.support:support-v4:28.0.0-beta01'  //overwritten

无法加载具有未知错误的AppCompat ActionBar。 beta01 3.1.3 helpme，请
