我已将项目compileSdkVersion从28迁移到29，并在清单中添加 android:requestLegacyExternalStorage="true"，但下载和文件打开等文件操作无法像在 SDK 28 中那样工作

梯度文件

compileSdkVersion 29

defaultConfig {
    applicationId "in.example.app"
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 90
    versionName "1.8.3"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
