在android应用程序中创建flavor时出现内容提供商问题

我已经为android项目创造了风格。 下面是我在gradle文件中实现的更改

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'
    defaultConfig {
        applicationId "com.collegemobile.free.free"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 5
        versionName "2.1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        renderscriptTargetApi 23
        renderscriptSupportModeEnabled true

    }

    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    flavorDimensions"default"
    productFlavors{
            paid{
                buildConfigField("String","paid","paid")
                applicationId 'com.collegemobile.paid.paid'
                 dimension "default"

            }
            free{
                buildConfigField("String", "free", "free") 
                applicationId 'com.collegemobile.free.free'
                dimension "default"

            }
        }

它工作正常，但现在它显示了内容提供商的问题。 我在Manifest.xml文件中做了以下更改。在android:authorities=“${applicationId}中，我添加了$applicationId

<provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>




<provider
            android:name=".models.DataProvider"
            android:authorities="${applicationId}"
            android:exported="false"
            android:syncable="true"></provider>
