TelecomManager.ACTION_CHANGE_DEFAULT_DIALER returns RESULT_CANCELED on huawei P8 Lite

问题

I want to change Android default dialer and want to make my own customized dialer. For this purpose I have choose this GIthub repo as start up project. This works well on all other phone and stops working on huawei p8 lite. The default pop up message does not shows up for setting the app as default. Here is code block

 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)
    }

    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()
    }

StertActivityforResult returns with RESULT_CANCELED and message "User declined request to become default dialer" Cant find any solution for this. Any help will be greately appreciated.

Try to add some intent filters to your Activity in AndroidManifest.

<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>
