java READ_EXTERNAL_STORAGE权限请求未显示在模拟器上

我尝试设置一种方法,在Activity初始化后注册权限结果处理程序,方法是创建一个Map<Integer, Runnable>来保存处理程序,当我请求权限时,我使用随机生成的代码并将runnable保存到代码/处理程序的Map中。
这是我目前为止在活动课上学到的

private final HashMap<Integer, Runnable> onPermission = new HashMap<>();

//i call this from other classes to ask for a permission and register a handler
public void requestPermission(Runnable onGranted, String...permissions) {
    int code = Permissions.permissionRequestCode();
    onPermission.put(code, onGranted);
    requestPermissions(permissions, code);
}

//overriding this method to check if the Map has a handler for the granted request
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    Runnable handler = onPermission.get(requestCode);
    if (handler != null && isGranted(grantResults)) {
        handler.run();
        onPermission.remove(requestCode);
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

//utility method to check if all the requested permissions are granted
private boolean isGranted(int[] results) {
    for (int i : results) {
        if (i != PackageManager.PERMISSION_GRANTED) {
            return false;
        }
    }
    return true;
}

下面是一个如何使用它的示例,其中owner是一个my Activity示例:

private void readImages() {
    if (ContextCompat.checkSelfPermission(owner, Manifest.permission.READ_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_GRANTED) {
        loadImages();
    } else {
        owner.requestPermission(this::loadImages, Manifest.permission.READ_EXTERNAL_STORAGE);
    }
}

现在在实际设备上运行(Android 12,API 31),工作原理完全符合我的预期(显示请求,并且在授予权限时执行处理程序),但是在模拟器上(Android 13,API 33),请求权限时没有任何显示,并且它保持"未授予",权限甚至不会显示在"应用程序信息"中,即使它包含在清单中。
真实器械:

模拟器:

我的清单:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="Mesa"
        android:roundIcon="@mipmap/ic_launcher"
        android:supportsRtl="true"
        android:theme="@style/Theme.Mesa.NoActionBar"
        android:usesCleartextTraffic="true">
        <activity
            android:name=".app.Mesa"
            android:configChanges="uiMode|screenSize|colorMode"
            android:exported="true"
            android:theme="@style/Theme.Mesa.NoActionBar"
            android:windowSoftInputMode="adjustResize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

我的身材。

android {
    compileSdk 33

    defaultConfig {

        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        proguardFiles 'proguard-rules.pro'
    }

    buildTypes {
        release {
            minifyEnabled true
        }

        debug {
            minifyEnabled false
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
        allprojects {
            tasks.withType(JavaCompile){
                options.compilerArgs <<"-Xlint:deprecation"
            }
        }
    }
    buildFeatures {

    dependenciesInfo {

自Android 13及更高版本起,请求READ_EXTERNAL_STORAGE的应用必须改为请求以下一个或多个更细粒度的权限:

  • READ_MEDIA_IMAGES
  • READ_MEDIA_VIDEO
  • READ_MEDIA_AUDIO
