Enable input file camera on android webview

Question

I am creating a webview, to load an external website.

On this site I have a form with an input file. Clicking it should open the cell phone\'s camera, but it doesn\'t

Answer 1

First, you should add below code in your HTML file

After creating one class in the Android side

class WebAppInterface(private val mContext: Context) {

    /** Show a toast from the web page  */
    @JavascriptInterface
    fun openCamera() {
        //This method called when user clicks on webview button.
        Toast.makeText(mContext, open Camera, Toast.LENGTH_SHORT).show()
    }
}

and add WebAppInterface handler to you webview

webView.addJavascriptInterface(WebAppInterface(this), "Android")

For Example

public class MainActivity extends AppCompatActivity {

    private WebView webView;

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

        this.getSupportActionBar().hide();

        webView = findViewById(R.id.webView);
        webView.setWebViewClient(new WebViewClient());
        webView.loadUrl("https://apps.url/loja/index.php");

        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
      webView.addJavascriptInterface(WebAppInterface(this), "Android")


    }
}
class WebAppInterface(private val mContext: Context) {

    /** Show a toast from the web page  */
    @JavascriptInterface
    fun openCamera() {
        //This method called when user clicks on webview button.
        Toast.makeText(mContext, open Camera, Toast.LENGTH_SHORT).show()
    }
}
