How Do I Update The Widget's TextViewText From A Broadcast Receiver?

I am trying to update my widget's TextView Text from a BroadcastReceiver on ClickPendingIntent. I am not having much luck. Can I please get some help with this? In my ActionReceiver.class which extends BroadcastReceiver, I know that I need to update the widget after changing the textview text. I am not sure how to do that. Unfortunately, I can't use statics without crashing the app and widget. Here is my code...

It's still not working for me. When I click the textview on the widget, it just launches the app. I'm trying to get the textview to change the default word "Example" to "Hello World" when the textview is clicked on. I've been trying for hours figuring this out.

Call measure how far you dragged in Android

I made an application running in the background, and I want to add a function to measure the slide on the screen. I'll leave you the code for both, and someone can help me. I'm a beginner and I've been looking all over trying to solve this without results.
I know the post is too long, but I did not know how to shorten it so you can understand it.

How to create notification in Android with API 21 or higher

I have trouble creating notification from the application in Android. API must be API 21 or higher. I've probably tried 100 ways with Android Developer and other websites.
minSDK must be API21
I opened it on API26
This is my activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click for Notification"
android:id="#+id/buckysButton"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:onClick="buckysButtonClicked" />
</RelativeLayout>
This is MainActivity.java
package pl.wat.pz.notification;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
NotificationCompat.Builder notification;
private static final int uniqueID = 45612;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
notification = new NotificationCompat.Builder(this);
notification.setAutoCancel(true);
}
public void buckysButtonClicked(View view){
//Build the notification
notification.setSmallIcon(R.mipmap.ic_launcher);
notification.setTicker("This is the ticker");
notification.setWhen(System.currentTimeMillis());
notification.setContentTitle("Here is the title");
notification.setContentText("I am the body text of your notification");
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setContentIntent(pendingIntent);
//Builds notification and issues it
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.notify(uniqueID, notification.build());
}
}
And the manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pl.wat.pz.notification">
<application
android:allowBackup="true"

android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And here image from android emulator
After click button nothing happened ;((

notification.setSmallIcon(R.mipmap.ic_launcher);
AFAIK, you cannot use a mipmap resource here, and your launcher icon is not a suitable notification icon on Android 4.4 and higher.
Create a separate drawable resource for your notification icon. If you are using Android Studio, the Image Asset wizard can assist with this.
Also, if your targetSdkVersion is 26 or higher, you need to set up a notification channel when running on Android 8.0+. This directory contains many sample apps that are up-to-date with respect to raising a Notification.
