After struggling a lot I found a code that works for taking files from galley and camera from 5.0+ devices
private ValueCallback<Uri> mUploadMessage;
private Uri mCapturedImageURI = null;
private ValueCallback<Uri[]> mFilePathCallback;
private String mCameraPhotoPath;
private static final int INPUT_FILE_REQUEST_CODE = 1;
private static final int FILECHOOSER_RESULTCODE = 1;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File imageFile = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
return imageFile;
}
this is initialization and setting webview
mWebView= (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginState(WebSettings.PluginState.OFF);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setUserAgentString("Android Mozilla/5.0 AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30");
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setAllowContentAccess(true);
mWebView.getSettings().supportZoom();
mWebView.loadUrl(Common.adPostUrl);
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// do your handling codes here, which url is the requested url
// probably you need to open that url rather than redirect:
if ( url.contains(".pdf")){
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(url), "application/pdf");
try{
view.getContext().startActivity(intent);
} catch (ActivityNotFoundException e) {
//user does not have a pdf viewer installed
}
} else {
mWebView.loadUrl(url);
}
return false; // then it is not handled by default action
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Log.e("error",description);
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) { //show progressbar here
super.onPageStarted(view, url, favicon);
}
@Override
public void onPageFinished(WebView view, String url) {
//hide progressbar here
}
});
mWebView.setWebChromeClient(new ChromeClient());
and here is my ChomeClient() method
public class ChromeClient extends WebChromeClient {
// For Android 5.0
public boolean onShowFileChooser(WebView view, ValueCallback<Uri[]> filePath, WebChromeClient.FileChooserParams fileChooserParams) {
// Double check that we don't have any existing callbacks
if (mFilePathCallback != null) {
mFilePathCallback.onReceiveValue(null);
}
mFilePathCallback = filePath;
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
takePictureIntent.putExtra("PhotoPath", mCameraPhotoPath);
} catch (IOException ex) {
// Error occurred while creating the File
Log.e(Common.TAG, "Unable to create Image File", ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {
mCameraPhotoPath = "file:" + photoFile.getAbsolutePath();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
} else {
takePictureIntent = null;
}
}
Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);

return true;
}
// openFileChooser for Android 3.0+

// Create AndroidExampleFolder at sdcard
// Create AndroidExampleFolder at sdcard

if (!imageStorageDir.exists()) {

}
// Create camera captured image file path and name

// On select image call onActivityResult method of activity
startActivityForResult(chooserIntent, FILECHOOSER_RESULTCODE);
}
// openFileChooser for Android < 3.0

openFileChooser(uploadMsg, "");
}
//openFileChooser for other Android versions
public void openFileChooser(ValueCallback<Uri> uploadMsg,

}
}
//here is my onActivityResult method to handle data from gallery or camera intent
@Override

if (mCameraPhotoPath != null) {

}
} else {

if (dataString != null) {

}
}

Toast.makeText(getApplicationContext(), "activity :" + e,
Toast.LENGTH_LONG).show();

return;
}
and here is the permissions required to open camera
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.CAMERA2" /> // for new versions api 21+
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Note: My code also contains the code for devices running 3.0+ also but I never tested them , the above code worked on Lolipop, Marshmallow and Nougat emulators.
One more thing , if you see and icon of Android System in place of Camera it means you have many apps available in your device to handle camera.
