Admob Interstitial the ad does not appear, what is wrong?

even putting the test id does not appear, I've made countless attempts, I found that it can be linked to mInterstitialAd.isLoaded (), but I can't solve it
I also tried to make modifications to the mInterstitialAd.setAdListener, nothing else happens, can someone help me?

Why is my app not displaying recorded message?

So, I am creating an AI music player app. Everything seems fine but whenever I give it some voice command, it does not display the required message.
I have tried using different emulators and using different android versions. None of those worked.
package com.learning.intelligentmusicplayer;

import android.widget.Toast;
import java.util.ArrayList;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
private RelativeLayout parentRelativeLayout;
private SpeechRecognizer speechRecognizer;
private Intent speechRecogniserIntent;
private String keeper="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
checkVoiceCommandPermission();
parentRelativeLayout = findViewById(R.id.parentRelativeLayout);
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(MainActivity.this);
speechRecogniserIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
speechRecogniserIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM );
speechRecogniserIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
speechRecognizer.setRecognitionListener(new RecognitionListener() {
#Override
public void onReadyForSpeech(Bundle bundle) {
}
#Override
public void onBeginningOfSpeech() {

}
#Override
public void onResults(Bundle bundle) {
ArrayList<String> matchesFound = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
if(matchesFound!=null)
{
keeper = matchesFound.get(0);
Toast.makeText(MainActivity.this, "Result = "+keeper, Toast.LENGTH_LONG).show();
}
}
#Override
public void onPartialResults(Bundle bundle) {
}
#Override
public void onEvent(int i, Bundle bundle) {
}
});
parentRelativeLayout.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch(motionEvent.getAction())
{
case MotionEvent.ACTION_DOWN:
speechRecognizer.startListening(speechRecogniserIntent);
keeper="";
break;
case MotionEvent.ACTION_UP:
speechRecognizer.stopListening();
break;
}
return false;
}
});
}
private void checkVoiceCommandPermission()
{
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
if(!(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.RECORD_AUDIO)==PackageManager.PERMISSION_GRANTED))
{
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package: "+getPackageName()));
startActivity(intent);
finish();
}
}
}
}
There is no error message. I hear the beep sound for recording message but it does not display the message on screen.

Downloading Google voice assistant fixed my problem!
