The official Facebook for Android SDK is open source, have a look
http://github.com/facebook/facebook-android-sdk

I was having the same case and solved the problem by implementing a webview client and webchrome client as shown below. I have done a sample demonstrating the same how to upload photos on your android application. Try these code and it will definitely work for you. You can download a working demo from here

Besides, add the permissions for internet access, read from external storage and camera capture.

You can use this class: https://github.com/delight-im/Android-AdvancedWebView

This code is working for me.....

I'm new to Andriod and struggled with this also. According to Google Reference Guide WebView.
By default, a WebView provides no browser-like widgets, does not enable JavaScript and web page errors are ignored. If your goal is only to display some HTML as a part of your UI, this is probably fine; the user won't need to interact with the web page beyond reading it, and the web page won't need to interact with the user. If you actually want a full-blown web browser, then you probably want to invoke the Browser application with a URL Intent rather than show it with a WebView.
Example code I executed in MainActvity.java.
Uri uri = Uri.parse("https://www.example.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
Excuted
package example.com.myapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.content.Intent;
import android.net.Uri;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

I hope this helpful to you!

The problem here is that in Android 4.4 the file input is not implemented and it will never work through the standard WebView interface.
What I did in my project has been to use CrossWalk project to make it work fine.
It has required quite a bit of work to change the default WebView from the standard Android one to CrossWalk, however it really served my needs quite well.
Basically you need to replace the normal Android WebView with the CrossWalk webView. This had few advantages for us, including the fact that Chrome will be updated even on Android 4.0, 4.1 etc, giving us a much better support and fewer bugs.
I documented how I implemented it here: http://blog.maurizionapoleoni.com/blog/implementing-a-file-input-with-camera-support-in-android-with-crosswalk/

This code is running fine on my side.
private class MyWebChromeClient extends WebChromeClient {
//The undocumented magic method override
//Eclipse will swear at you if you try to put #Override here
// For Android 3.0+
public void openFileChooser(ValueCallback uploadMsg, String acceptType) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity1.this.startActivityForResult(Intent.createChooser(i, "File Browser"), FILECHOOSER_RESULTCODE);
}
//For Android 4.1+ only
protected void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture)
{
mUploadMessage = uploadMsg;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
startActivityForResult(Intent.createChooser(intent, "File Browser"), FILECHOOSER_RESULTCODE);
}
protected void openFileChooser(ValueCallback<Uri> uploadMsg)
{
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
}
// For Lollipop 5.0+ Devices
public boolean onShowFileChooser(WebView mWebView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams) {
if (uploadMessage != null) {
uploadMessage.onReceiveValue(null);
uploadMessage = null;
}
uploadMessage = filePathCallback;
Intent intent = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
intent = fileChooserParams.createIntent();
}
try {
startActivityForResult(intent, REQUEST_SELECT_FILE);
} catch (ActivityNotFoundException e) {

button does not respond in Webview

Everything in the android web app is working as expected except the html file input fields coded as <input type="file" name="filn"/> in webpage.When i click on the button supposed to load the resources in which the files can be chosen from, it does not respond. Meanwhile in google browser, it works fine. My webview android code is as follows:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview =(WebView)findViewById(R.id.webView1);
webview.setWebViewClient(new WebViewClient());
webview .getSettings().setJavaScriptEnabled(true);
webview.loadUrl("website");
}
What can i do to make it work?
present class which does not work also. I am trying to load a file from html file input in a jsp.
public class WebViewActivity extends Activity {
private String url = "website";

if(requestCode==FILECHOOSER_RESULTCODE) {
if (null == mUploadMessage) return;

mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
}
#Override

Enable attachment in WebView android

public class WebViewDialogActivity extends Activity
{
//Create a dialog object, that will contain the WebView

//The button to launch the WebView dialog
private Button btLaunchWVD;
//The button that closes the dialog
private Button btClose;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.sliding_menu_categories);
//Inflate the btLaunchWVD button from the 'main.xml' layout file
btLaunchWVD = (Button) findViewById(R.id.bt_launchwvd);
//Set the 35. OnClickListener for the launch button
btLaunchWVD.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
//Display the WebView dialog
webViewDialog.show();
}
});
//Create a new dialog
webViewDialog = new Dialog(this);
//Remove the dialog's title
webViewDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Inflate the contents of this dialog with the Views defined at 'webviewdialog.xml'
webViewDialog.setContentView(R.layout.webviewdialog);
//With this line, the dialog can be dismissed by pressing the back key
webViewDialog.setCancelable(true);
//Initialize the Button object with the data from the 'webviewdialog.xml' file
