    As Docs mentioned, To allow HTTP and HTTPS network requests on devices with targetSdkVersion 28 or later, pls configure the following information in the AndroidManifest.xml file:

    <application
    ...
    android:usesCleartextTraffic="true"
    >
    ...
</application>

    Then change targetSdk 30 in Gradle to 29.

    enter image description here

    recommended versions are as in the link

    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId ""
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    Huawei Y6p has encountered the same problem before on this device. You can check there is a SIM card.

    After the SIM is inserted, the country code of the SIM card will be read.
    Rules for obtaining the country code: country code of the place of shipment> country code of the sim card> country set by the mobile phone.
