我希望我的应用程序成为默认拨号器，但是当我尝试为用户创建对话框以设置默认应用程序时，我的应用程序本身拒绝它（它显示吐司“用户拒绝成为默认拨号器的请求）在三星 Galaxy S10+ 我的测试MainActivity.kt：

class MainActivity : BaseActivity() {
    companion object {
        private const val REQUEST_CODE_SET_DEFAULT_DIALER = 100
    }
    override val navigationGraphResId = R.navigation.nav_graph

    @RequiresApi(Build.VERSION_CODES.M)
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        checkDefaultDialer()
    }

    private fun checkDefaultDialer() {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) return

        val telecomManager = getSystemService(TELECOM_SERVICE) as TelecomManager
        val isAlreadyDefaultDialer = packageName == telecomManager.defaultDialerPackage
        if (isAlreadyDefaultDialer) return

        val intent = Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER)
            .putExtra(TelecomManager.EXTRA_CHANGE_DEFAULT_DIALER_PACKAGE_NAME, packageName)

        startActivityForResult(intent, REQUEST_CODE_SET_DEFAULT_DIALER)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            REQUEST_CODE_SET_DEFAULT_DIALER -> checkSetDefaultDialerResult(resultCode)
        }
    }

    private fun checkSetDefaultDialerResult(resultCode: Int) {
        val message = when (resultCode) {
            RESULT_OK       -> "User accepted request to become default dialer"
            RESULT_CANCELED -> "User declined request to become default dialer"
            else            -> "Unexpected result code $resultCode"
        }

        Toast.makeText(this, message, Toast.LENGTH_SHORT).show()
    }

}

我在 AndroidManifest.xml 中放置了意图过滤器：

 <activity
            android:name=".MainActivity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

            <intent-filter>
                <action android:name="android.intent.action.VIEW"/>
                <action android:name="android.intent.action.DIAL"/>

                <category android:name="android.intent.category.DEFAULT"/>
                <category android:name="android.intent.category.BROWSABLE"/>

                <data android:scheme="tel"/>
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.DIAL"/>

                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>

        </activity>

感谢帮助
