Migration 找不到AndroidX FrameLayout\u heightPercent属性错误

尝试将我的Android项目从API 25升级到AndroidX，我在布局中使用了以下内容

<FrameLayout
        android:id="@+id/frame0"
        app:layout_heightPercent="10%"
        android:layout_marginTop="50dp"
        android:layout_height="wrap_content"
        android:layout_width="match_parent">

    <com.google.android.gms.ads.AdView
        android:id="@+id/adViewFirstPage1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_1"
        android:layout_gravity="center"
        />

现在我发现了一些错误，比如 在FrameLayout中找不到布局\高度百分比错误 AAPT:错误：在AdMob横幅中未找到属性adUnitId

据我所知，我找不到合适的图书馆。一点帮助会非常有用。

以下是app gradle文件内容

apply plugin: 'com.android.application'

        applicationId "com.myproject"

下面是gradle项目

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath 'com.google.gms:google-services:4.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

更新后，我们需要重构项目。有时我们需要相应地更改项目中的导入语句

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath 'com.google.gms:google-services:4.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
