Android emulator can't get api data threw frontend website

I have frontend and backend ready and working on localhost. I am displaying the frontend website threw the android emulator:

public class MainActivity extends AppCompatActivity {

    private WebView webview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webview =(WebView)findViewById(R.id.webView);

        webview.setWebViewClient(new WebViewClient());
        webview.getSettings().setJavaScriptEnabled(true);
        webview.getSettings().setDomStorageEnabled(true);
        webview.setOverScrollMode(WebView.OVER_SCROLL_NEVER);
        webview.loadUrl("http://10.0.2.2:4200/mobile");

    }
}

The problem is that emulator can't get the data from database or send request to api to recieve the data so that it's not displayed. How it looks on a website: Once again the problem is straight with emulator. I tried building the frontend in production mode with no success. Maybe I should declare special permission or sth like that.
