Action_Call permission not granted in Android Studio - android-studio

I am trying to make an app which can directly call if the number is entered but the permission is not granted and hence no call is made...
I have requested permission in AndriodManifest.xml
Everytime I enter a number, "Hello" pops up which is written if Granted is Not Granted.
My code:
MainActivity.java
package com.example.block9;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void redirectmessage(View v) {
String number = (((EditText) findViewById(R.id.mobnumber)).getText()).toString();
String message = (((EditText) findViewById(R.id.textmessage)).getText()).toString();
Uri num = Uri.parse("smsto:" + number);
Intent smsIntent = new Intent(Intent.ACTION_SENDTO, num);
smsIntent.putExtra("sms_body", message);
startActivity(smsIntent);
}
public void redirectcall(View v) {
String number = (((EditText) findViewById(R.id.mobnumber)).getText()).toString();
Toast t = null;
//t.makeText(getApplicationContext(),number,Toast.LENGTH_SHORT).show();
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + number));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
t.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT).show();
return;
}
startActivity(callIntent);
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.block9">

Any Help would be Appreciated!!`enter code here.

If your Target Device API is <22 then you don't need to ask for permission as the permission will automatically provide But as a Developer you have to ready for every possibility. in case if target device API is >=23 then you have to manually request the permission. For more information on this Read this
public void redirectcall(View v) {
String number = (((EditText) findViewById(R.id.mobnumber)).getText()).toString();
Toast t = null;
//t.makeText(getApplicationContext(),number,Toast.LENGTH_SHORT).show();
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + number));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
t.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT).show();
grantPermission();
return;
}
startActivity(callIntent);
}
private void grantPermission() {
// show your dialog box to ask for permission
new AlertDialog.Builder(this)
.setTitle("Call Permission Required")
.setMessage("This App needs Call permission, to function properly")
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "Permission Denied", Toast.LENGTH_SHORT)
.show();
}
})
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//here permission will be given
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE}, 3); // 3 is requestCode and can be any number
}
})
.create()
.show();
}
After Making a Request Now, we will call #Override method onRequestPermissionsResult() to handle the scenario of Rejected or accepted Request
*#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode){
case 3: //remember that 3 is the same number which we specified while requesting
{
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// Call-related task you need to do.
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.CALL_PHONE)
== PackageManager.PERMISSION_GRANTED) {
redirectcall();
}
}else{
// permission denied, boo! Disable the
// functionality that depends on this permission.
Toast.makeText(this, "permission denied", Toast.LENGTH_LONG).show();
}
}
}
}*

java.lang.NullPointerException in onCreate for some SDK versions

Recently I have updated the webview code and updated the apk on playstore. On update, some of the devices are not able to open the app; specifically Android 12 devices. Tried to take reference from other stack post to solve it, but nothing seems to address this specific issue.
Would appreciate if you go through the code below and let me know the issue.

How to load an image in Android Studio using a Processing sketch

I cannot load an image using a Processing sketch.
I am using Android Studio on Windows 10 with an android emulator. I have placed an image file called "car.png" in the following directory:
E:\Android\AndroidStudioProjects\car\app\src\main\res\drawable
I also placed it in the following directory using the Device File Explorer of Android Studio:
/data/user/0/com.example.ijusttrytoloadanimage/files/
When I double-click it from the Project tree or from the Device File Explorer, it shows the car image.
But when I run my project in Android Emulator I get the following error message:
W/System.err: java.io.FileNotFoundException: /data/user/0/com.example.ijusttrytoloadanimage/files/car.png (Permission denied)
This is my Sketch.java file:
package com.example.ijusttrytoloadanimage;
import processing.core.PApplet;
import processing.core.PImage;
public class Sketch extends PApplet {
public PImage car;
public void settings() {
fullScreen();
}
public void setup() {
imageMode(CENTER);
car = loadImage("car.png");
}
public void draw() {
background(0);
translate((float) width/2, (float) height/2);
if (car != null) {
image(car, 0, 0);
} else {
print("nothing shows up!");
}
}
The message I get when running the Sketch.java is "nothing shows up!" meaning that the PImage variable car is still empty.
Why I get this permission denied message although I use the internal storage which by default has its access granted? What should I do to show my image file to the emulator's screen?
This is my MainActivity.java file:
package com.example.ijusttrytoloadanimage;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import processing.android.PFragment;
import processing.android.CompatUtils;
import processing.core.PApplet;
public class MainActivity extends AppCompatActivity {
private PApplet sketch;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FrameLayout frame = new FrameLayout(this);
frame.setId(CompatUtils.getUniqueViewId());
setContentView(frame, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
sketch = new Sketch();
PFragment fragment = new PFragment(sketch);
fragment.setView(frame, this);
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (sketch != null) {
sketch.onRequestPermissionsResult(
requestCode, permissions, grantResults);
}
}
#Override
public void onNewIntent(Intent intent) {
super.onNewIntent(intent);
if (sketch != null) {
sketch.onNewIntent(intent);
}
}
}
This is my AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ijusttrytoloadanimage">
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.ijusttrytoloadanimage"
>
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I finally found the answer. If anyone else has the same problem, just do the following:
In Project View right-click on app and select New -> Directory. Type the name "assets" in the new window and select src/main/assets from below.
Copy your image file to the new directory app/src/main/assets.
Load your image in your Sketch.java file with the command loadImage(your_image.png);
It works!

when run this on android version 8.0 or below its work well ... but the problem is on version 9 or above ??
just put the below line in manifest under application tag and try
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
if doesnt work try adding below line
android:usesCleartextTraffic="true under application tag and even if it doesnt work try adding android:networkSecurityConfig="#xml/network_security_config in application tag where network_security_config.xml is<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
Create xml under res directory and then network_security_config.xml in xml folder
