Android13（targetSdk33）POST_NOTIFICATIONS权限弹窗不显示求助

试过多种方案均无效，核心问题是调用ActivityCompat.requestPermissions时，请求通知权限的弹窗完全不触发。

环境配置 #

• 测试设备：Android 13物理机（三星Galaxy S22、Galaxy A51）
• targetSdkVersion = 33
• compileSdkVersion = 33
• minSdkVersion = 23
• AndroidManifest已添加权限：<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

AndroidManifest中Activity声明 #

<activity android:name=".PostNotificationActivity"
    android:exported="true"
    android:screenOrientation="portrait"/>

按钮点击逻辑代码 #

if (ContextCompat.checkSelfPermission(this, Manifest.permission.POST_NOTIFICATIONS) != PackageManager.PERMISSION_GRANTED) {
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.POST_NOTIFICATIONS)) {
        ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.POST_NOTIFICATIONS),
            POST_NOTIFICATION_PERMISSION_CODE)

    } else {
        ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.POST_NOTIFICATIONS),
            POST_NOTIFICATION_PERMISSION_CODE)
    }
}

权限请求回调代码 #

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<out String>,
    grantResults: IntArray
) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)

    when(requestCode) {
        POST_NOTIFICATION_PERMISSION_CODE -> {
            if (grantResults.size > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(applicationContext, "Permission Granted", Toast.LENGTH_LONG).show()

            } else {
                Toast.makeText(applicationContext, "Permission Denied", Toast.LENGTH_LONG).show()
            }

            return
        }
    }
}

调试排查情况 #

• 首次点击按钮：通过调试确认已调用requestPermissions，但设备无权限弹窗，onRequestPermissionsResult未触发
• 再次点击按钮：仍调用requestPermissions，无弹窗，但onRequestPermissionsResult触发并返回“Permission Denied”，返回上一Activity时出现界面冻结
• 尝试替换为ActivityResultLauncher实现，问题依旧，无权限弹窗
