Saripaar Validation library throws No rules found error

I'm trying to use Saripaar Validation on my project, but it's throwing the following error:
java.lang.IllegalStateException: No rules found. You must have at
least one rule to validate. If you are using custom annotations, make
sure that you have registered them using the 'Validator.register()'
method.
My architecture separates the responsibility for handling the view into a class, for example for LoginActivity I have LoginView, which is where I handle my view logic like ButterKnife injection, event listening, etc. In this class I have my annotated fields.My LoginView looks like this:
import android.content.res.ColorStateList;

From what I'm guessing, the library is trying to find these fields on my Activity, and since they're not there, then it's throwing this error.
Is there a way use this library accordingly to the architecture I'm handling?

use validator = new Validator(this) in place of validator = new Validator(context);

Not annotated parameter overrides #NonNull parameter
This is just a warning. You have
#Override
public View onCreateView(LayoutInflater inflater...
while the base class you're extending has nullity annotation on the inflater parameter.
public View onCreateView(#NonNull LayoutInflater inflater...
You can just alt-enter in Android Studio to get a quick fix menu that has the option to add the missing annotation there.
due to this error my code is not working.
Missing an annotation like that just causes a warning. The reason for "not working" is something else. Please start by updating your question and specifying what "not working" means to you here.

Try to change this line
View v = inflater.inflate(R.layout.fragment_files_listing, null);
to
View v = inflater.inflate(R.layout.fragment_files_listing, container, false);
This will inflate your layout with your fragment container.

You have to change this line
View v = inflater.inflate(R.layout.fragment_files_listing, null);
to
View v = inflater.inflate(R.layout.fragment_files_listing, container, false);
and then clean your project and invalidate cache restart you android studio.

Dynamically add and animate new ListView item on the beginning - scrolling issue

I have a ListFragment, with a simple ListView. I'm adding new items to this ListView dynamically, when there is a new message on a WebSocket. I'm adding the new row to the beginning of my ArrayAdapter, and there is a simple animation when new item added.
The problem is, when animation is going on, and I'm trying to scroll, older items are also animated on the ListView, only when I'm scrolling fast.

and the ListFragment:

yes recycling is the problem. When you add the animation in your adapter, you have to put a "remove animation code":
if (mRecentAddedIndex == i && mRecentAnimated && mRecentAdded.equals(mLiveData.get(i)))
{
mRecentAnimated = false;
Animation ANIM_APPEAR = AnimationUtils.loadAnimation(getContext(), R.anim.push_right_in);
ANIM_APPEAR.setDuration(500);
view.findViewById(R.id.live_holder_parent).startAnimation(ANIM_APPEAR);
AndroidLogger.PushDebugMessage("Animáció megtörtént: "+mRecentAddedIndex+" "+mLiveData.get(i).Settlement);
} else {
// remove animation

The final code: (cleaned, animation went final, etc etc)
if (mRecentAddedIndex == i && mRecentAnimated && mRecentAdded.equals(mLiveData.get(i)))
{
mRecentAnimated = false;
layout.startAnimation(ANIM_APPEAR);
AndroidLogger.PushDebugMessage("Animáció megtörtént (Animation occurred): "+mRecentAddedIndex+" "+mLiveData.get(i).Settlement);
}
else
{
layout.clearAnimation();
}

Making a call when button pressed on Arduino

Hi I'm trying to combine 2 projects
1. that tells me wen button on arduino pressed
2. make a call on android
what im trying to do is when button pressed on arduino make a call..
but with no luck :(
Call
package net.mitchtech.adb;
import net.mitchtech.adb.simpledigitalinput.R;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
public class phonecalls extends Activity {
private void call() {
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:048598077"));
startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
Log.e("dialing-example", "Call failed", activityException);
}
}
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.input);
}
}
buttons
package net.mitchtech.adb;
import net.mitchtech.adb.simpledigitalinput.R;
import net.mitchtech.adb.phonecalls;
import org.microbridge.server.AbstractServerListener;
import org.microbridge.server.Server;
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.TextView;
public class ButtonView extends FrameLayout {
private static final String TAG = ButtonView.class.getSimpleName();
private final View mButtonView;
private Server mServer;
private final int BUTTON1 = 2;
private final int BUTTON2 = 3;
public ButtonView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mButtonView = inflater.inflate(R.layout.input, this);
}
public void setServer(Server server) {
mServer = server;
mServer.addListener(new AbstractServerListener() {
#Override
public void onReceive(org.microbridge.server.Client client, byte[] data) {
if (data.length < 2)
return;
final int pinNumber = data[0];
final int pinState = data[1];
Log.i(TAG, "data[0]:" + pinNumber + " data[1]:" + pinState);
final TextView positionText = (TextView) findViewById(R.id.activeText);
class InputAction implements Runnable {
public void run() {
switch (pinNumber) {
case BUTTON1:
if (pinState == 1) {
call();
positionText.setText("Button 1 Active");
} else {
positionText.setText("");
}
break;
case BUTTON2:
if (pinState == 1) {
positionText.setText("Button 2 Active");
} else {
positionText.setText("");
}
break;
default:
break;
}
}
};
InputAction action = new InputAction();
post(action);
}
});
}
public View getmButtonView() {
return mButtonView;
}
}
and another activity
package net.mitchtech.adb;
import java.io.IOException;
import net.mitchtech.adb.simpledigitalinput.R;
import org.microbridge.server.Server;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class SimpleDigitalInputActivity extends Activity {
private final static String TAG = SimpleDigitalInputActivity.class.getSimpleName();
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Server server = null;
try
{
server = new Server(4567);
server.start();
ButtonView buttonView = (ButtonView) findViewById(R.id.inputView);
buttonView.setServer(server);
} catch (IOException e)
{
Log.e(TAG, "Unable to start TCP server", e);
System.exit(-1);
}
}
}

Your call() function is declared in your activity, but you're trying to access it in your ButtonView class. Try moving it into ButtonView (copy & paste).
