Android Kotin：要求用户将应用设置为默认短信处理程序不起作用

问题描述

我正在使用 Kotlin 构建一个 Android 应用。我正在尝试将我的应用程序构建为默认 SMS 处理程序，因为它要求 SMS 权限，因此我需要确保它暗示了 Google PlayStore 的政策。但它没有显示任何弹出窗口或对话框来提示用户将应用程序设置为默认 SMS 处理程序。这是我的代码。

val setSmsAppIntent = Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT)
        setSmsAppIntent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,packageName)
        startActivityForResult(setSmsAppIntent,DEFAULT_SMS_HANDLER_REQUEST)

当我运行我的代码时，它没有显示任何内容。我的代码有什么问题，我该如何解决？

我也试过这个。

 private fun askDefaultSmsHandlerPermission() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            val roleManager: RoleManager = getSystemService(RoleManager::class.java)
            // check if the app is having permission to be as default SMS app
            val isRoleAvailable = roleManager.isRoleAvailable(RoleManager.ROLE_SMS)
            if (isRoleAvailable) {
                // check whether your app is already holding the default SMS app role.
                val isRoleHeld = roleManager.isRoleHeld(RoleManager.ROLE_SMS)
                if (isRoleHeld) {
                    val roleRequestIntent = roleManager.createRequestRoleIntent(RoleManager.ROLE_SMS)
                    startActivityForResult(roleRequestIntent,DEFAULT_SMS_HANDLER_REQUEST)
                }
            }
        } else {
            val intent = Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT)
            intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,packageName)
            startActivityForResult(intent,DEFAULT_SMS_HANDLER_REQUEST)
        }
    }

它也不起作用。

这是我的andoridmanifest.xml

解决方法

在你的代码中

// check whether your app is already holding the default SMS app role.
val isRoleHeld = roleManager.isRoleHeld(RoleManager.ROLE_SMS)
if (isRoleHeld) {
                 ...
                }

角色不能被持有，所以将if条件改为

if (!isRoleHeld) {
...
}
