File chooser from gallery work but it doesn't work with camera in android webview

I am developing a webview. In attach a file, file chooser work only with gallery but it doesn't work with camera. When i tap in attach a file, app shows the option for gallery and camera. But when i select camera nothing happen. I found several other source with almost similar problem. But the solution doesn't help me.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

if (requestCode != INPUT_FILE_REQUEST_CODE || mFilePathCallback == null) {
super.onActivityResult(requestCode, resultCode, data);
return;
}

Uri[] results = null;

// Check that the response is a good one
if (resultCode == Activity.RESULT_OK) {
if (data == null) {
// If there is not data, then we may have taken a photo
if (mCameraPhotoPath != null) {
results = new Uri[]{Uri.parse(mCameraPhotoPath)};
}
} else {
String dataString = data.getDataString();
if (dataString != null) {
results = new Uri[]{Uri.parse(dataString)};
}
}
}

mFilePathCallback.onReceiveValue(results);
mFilePathCallback = null;

} else if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
if (requestCode != FILECHOOSER_RESULTCODE || mUploadMessage == null) {
super.onActivityResult(requestCode, resultCode, data);
return;
}

if (requestCode == FILECHOOSER_RESULTCODE) {

if (null == this.mUploadMessage) {
return;

}

Uri result = null;

try {
if (resultCode != RESULT_OK) {

result = null;

} else {

// retrieve from the private variable if the intent is null
result = data == null ? mCapturedImageURI : data.getData();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "activity :" + e,
Toast.LENGTH_LONG).show();
}

mUploadMessage.onReceiveValue(result);
mUploadMessage = null;

}
}

return;
}


Here,In WebChromeClient:

public class MyWebChromeClient 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(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);
contentSelectionIntent.setType("image/*");

Intent[] intentArray;
if (takePictureIntent != null) {
intentArray = new Intent[]{takePictureIntent};
} else {
intentArray = new Intent[0];
}

Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
chooserIntent.putExtra(Intent.EXTRA_TITLE, "Image Chooser");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);

startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);

return true;

}

// openFileChooser for Android 3.0+
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {

mUploadMessage = uploadMsg;
// Create AndroidExampleFolder at sdcard
// Create AndroidExampleFolder at sdcard

File imageStorageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES)
, "AndroidExampleFolder");

if (!imageStorageDir.exists()) {
// Create AndroidExampleFolder at sdcard
imageStorageDir.mkdirs();
}

// Create camera captured image file path and name
File file = new File(
imageStorageDir + File.separator + "IMG_"
+ String.valueOf(System.currentTimeMillis())
+ ".jpg");

mCapturedImageURI = Uri.fromFile(file);

// Camera capture image intent
final Intent captureIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);

Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");

// Create file chooser intent
Intent chooserIntent = Intent.createChooser(i, "Image Chooser");

// Set camera intent to file chooser
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS
, new Parcelable[] { captureIntent });

// On select image call onActivityResult method of activity
startActivityForResult(chooserIntent, FILECHOOSER_RESULTCODE);


}

// openFileChooser for Android < 3.0
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
openFileChooser(uploadMsg, "");
}

//openFileChooser for other Android versions
public void openFileChooser(ValueCallback<Uri> uploadMsg,
String acceptType,
String capture) {

openFileChooser(uploadMsg, acceptType);
}

}


For Image:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";


java.io.File xmlFile = new java.io.File((getBaseContext()
.getApplicationContext().getFileStreamPath("FileName.xml")
.getPath()));
return xmlFile;
}

Answer

This is helpful for me. But, Camera is not working for Nexus 5. For this, I use the following code at onActivity method :

if (resultCode == Activity.RESULT_OK) {
        if (data == null || data.getDataString() == null) {
            // If there is not data, then we may have taken a photo
            if (mCameraPhotoPath != null) {
                results = new Uri[]{Uri.parse(mCameraPhotoPath)};
            }
        } else {
            String dataString = data.getDataString();
            if (dataString != null) {
                results = new Uri[]{Uri.parse(dataString)};
            }
        }
    }

I add this : if (data == null || data.getDataString() == null) {...}
