Question

I have a button choose files in website, when you press the button on your computer it works and when you press the button on the phone does not work what solution, the site shows using WebView

        mywebsite = (WebView)findViewById(R.id.mywebsite);
        pd_loading = (ProgressBar)findViewById(R.id.pd_loading);
        mywebsite.getSettings().setLoadsImagesAutomatically(true);
        mywebsite.getSettings().setJavaScriptEnabled(true);


        mywebsite.setWebViewClient(new WebViewClient());
        mywebsite.loadUrl(Information.URL_Home);
        mywebsite.setWebViewClient(new WebViewClient(){

            public void onPageFinished(WebView view ,String url)
            {
                pd_loading.setVisibility(View.GONE);
                mywebsite.setVisibility(View.VISIBLE);
            }

            @Override
            public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
                Toasty.error(Home.this,"",Toast.LENGTH_SHORT,true).show();
            }

            public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {

                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("image/*");
                startActivityForResult(Intent.createChooser(i, "File Chooser"), 101);
                mUploadMessage = uploadMsg;
            }

            // For Android > 4.1 - undocumented method
            @SuppressWarnings("unused")
            public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
                openFileChooser(uploadMsg, "");

            }

            // For Android > 5.0
            @TargetApi(Build.VERSION_CODES.LOLLIPOP)
            public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams) {

                startActivityForResult(fileChooserParams.createIntent(), 101);
                return true;
            }

        });

onActivittyResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        switch (requestCode) {
            case 101:
                if (resultCode == RESULT_OK) {

                    Uri result = intent == null || resultCode != RESULT_OK ? null
                            : intent.getData();
                    if (mUploadMessage != null) {
                        mUploadMessage.onReceiveValue(result);
                    } else if (afterLolipop != null) {

                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                            afterLolipop.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, intent));
                            afterLolipop = null;
                        }
                    }
                    mUploadMessage = null;
                }
        }

When I faced a similar kind of issue, I have made use of setWebChromeClient() method found from this souce.

import android.app.AlertDialog;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.webkit.JavascriptInterface;
import android.webkit.ValueCallback;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
import android.widget.Toast;
import org.apache.http.util.EncodingUtils;

public class BrowserScreen extends Activity {

    private WebView webView;
    private String url = "url";


    private ValueCallback<Uri> mUploadMessage;
    private final static int FILECHOOSER_RESULTCODE = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.browser_activity);
        initFields();
        setListeners();


    }




    public void initFields() {
        // TODO Auto-generated method stub

        webView = (WebView) findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setBuiltInZoomControls(true);
        webView.getSettings().setAllowFileAccess(true);
    }


    public void setListeners() {
        // TODO Auto-generated method stub

        webView.setWebViewClient(new WebViewClient() {
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

                webView.loadUrl("about:blank");

                view.clearHistory();
            }


        });

        webView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {


            }

        });



            webView.loadUrl(url);

    }
