I would like to show the ShowCaseView only once when starting the app for the first time. I use SharedPreferences but when I call from onCreate, nothing happens, ShowCaseView is not displayed, when I delete SharedPreferences then ShowCaseView is displayed. What to do, please help.

    SpannableStringBuilder ssb = new SpannableStringBuilder(getString(R.string.showcaseview_body));

        if (!LoadPreferencesBoolean(getApplicationContext(), "firsttimeshow", false)) {
            new MaterialTapTargetPrompt.Builder(MainActivity.this)
                    .setTarget(R.id.settings_menu)
                    .setPrimaryText(R.string.showcaseview_settings_title)
                    .setSecondaryText(ssb)
                    .setPromptStateChangeListener(new MaterialTapTargetPrompt.PromptStateChangeListener() {
                        @Override
                        public void onPromptStateChanged(MaterialTapTargetPrompt prompt, int state) {
                            if (state == MaterialTapTargetPrompt.STATE_FOCAL_PRESSED) {
                            }
                        }
                    })
                    .show();
            ShowCaseViewPreferences(getApplicationContext(), "firsttimeshow", true);
        }

For this, you can use my library from here. You can use it this way to do the simple tasks in the app like yours.

But, to use it, first add it to your app like this:

1. Add nitpick to your settings.gradle file like this:

maven { url 'https://jitpack.io' }

2. Add the library to your build.gradle file like this:

implementation 'com.github.sambhav2358:TinyDB:1.91'

3. Click Sync now.

Now, you can easily use the library like given below

Try this in the activity:

public class MyActivity extends AppCompatActivity {
   //add these variable
   TinyDBManager tinyDB;
   private final String KEY_FIRST_TIME_OPEN = "kfto";
   ...
   
   @Override
   public void onCreate(Bundle mBundle){
      tinyDB = TinyDB.getInstance(this);
    
      boolean isOpeningFirstTime = tinyDB.getBoolean(KEY_FIRST_TIME_OPEN, true);
      if(isOpeningFirstTime){
         // the app opened first time. Show the target
         tinyDB.putBoolean(KEY_FIRST_TIME_OPEN, false); // very important
      }else{
         // the app already opened. Do not show the target
      }
      ...
   }
}

maybe your sharedPreferences return true and your condition equal false. check with debug.
