Java.lang.IndexOutOfBoundsException: Индекс: 0, Размер: 0, ошибка в SDK <= 29 ⇐ Android

[Гость]

У меня возникла ошибка java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 в SDK 29, хотя в SDK версии выше 29 она работает правильно.
Мой код тестовой активности:

Код: Выделить всё

          protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
toolbar = findViewById(R.id.toolbar);

setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle(testList.get(g_selected_cat_test_index).getTName());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
progressDialog= new Dialog(TestActivity.this);
progressDialog.setContentView(R.layout.dialog_layout);
progressDialog.setCancelable(false);
progressDialog.getWindow().setLayout(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT  );
dialogText =progressDialog.findViewById(R.id.dialog_text);
dialogText.setText("loading data ...");
progressDialog.show();

testRView = findViewById(R.id.testRecyclerview);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(RecyclerView.VERTICAL);
testRView.setLayoutManager(layoutManager);
loadTestNData(new MyCompleteListener() {
@Override
public void onSuccess() {
DbQuery.loadMyScore(new MyCompleteListener() {
@Override
public void onSuccess() {
TestNAdapter adapter = new TestNAdapter(DbQuery.testNumList);
testRView.setAdapter(adapter);
progressDialog.dismiss();
}

@Override
public void onFailure() {
Toast.makeText(TestActivity.this,"Something went wrong ! ploease try again later",Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
});

}

@Override
public void onFailure() {
Toast.makeText(TestActivity.this,"Something went wrong ! ploease try again later",Toast.LENGTH_SHORT).show();
progressDialog.dismiss();

}
});

}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

if(item.getItemId() == android.R.id.home)
{
TestActivity.this.finish();
}
return super.onOptionsItemSelected(item);
}
