Both screens are in different Classes.
But it simply crashes before LoginScreen can reach to Category Screen. Any clue why this is not working? I have been trying to figure out and i used different variations of codes but all led me to to nothing. I have also tried on a different project but that also led me to nowhere. Thanks in advance

};
myRecyclerList.setAdapter(adapter);
adapter.startListening();
}
public static class ChatsViewHolder extends RecyclerView.ViewHolder
{
CircleImageView profileImageView;
TextView Username, Userstatus;
CheckBox IsUserInGroup;
ChatsViewHolder(#NonNull View itemView)
{
super(itemView);
profileImageView = itemView.findViewById(R.id.users_profile_image);
Username = itemView.findViewById(R.id.users_name);
Userstatus = itemView.findViewById(R.id.users_status);
IsUserInGroup = itemView.findViewById(R.id.IsUserInGroup);
}
}
}
Can anyone help me please?

I fixed it by moving the code in the on success listener itself

QR scanning, result - "com.google.android.gms.vision.barcode.Barcode#ecd6456"

I have problem, dont know what to do, Goal is to make QR scanner, you enter value then press OK it should store the values in object podaci and to use same values in other activitiy.
But what happens it scans QR code but it doesnt show real value it shows something like this : "com.google.android.gms.vision.barcode.Barcode#ecd6456" and there is no value stored in object podaci in MainActivity.
here is my QR class :
import android.Manifest;

startActivity(main);
finish();
}
public void izadji(View view){

And here is my MainActivity class :

if(level <= 10 && !baterija_ispisano){
Toast.makeText(getApplicationContext(),

baterija_ispisano = true;
}else if(level >= 11 && baterija_ispisano){

}
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnSkenirajQR = findViewById(R.id.btnSkener);

txtIspis = findViewById(R.id.txtIspis);
}
public void open_Skener(View view){
Intent qrskeniranje = new Intent(this, QRActivity.class);
startActivityForResult(qrskeniranje,0);
finish();
}
public void open_Opcije(View view){
Intent opcije = new Intent(this, OpcijeActivity.class);
startActivity(opcije);
finish();
}
public void izadji(View view){
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(data != null){
String qr = data.getParcelableExtra("barcode");
String value = data.getParcelableExtra("vrijednost");
txtIspis.setText("Barcode vrijednost : " + qr);
} else {
txtIspis.setText("Nije ocitalo");
}
}
}
Ps :And it is changing value while im holding in front of QR code.

My LogCat is displaying idsactly what I described. Would really appreciate a fix guys!

I've seen this for a number of months on my S3 and it's never appeared to cause any problems. The answer here sounds probable to me.
