I tried to implement Voice Search by following steps here; ActionBar Mic Button(Voice Search) in SearchView
Everything is fine,I've added all necessary info to my AndroidManifest and searcabhle.xml so I'm able to see mic icon and Search Bar,the problem is when I try to search with voice after saying something,it doesn't find anything and app crashes,looks like something wrong with SetQuery and here's the full error;

And this is my Main3Activity;

jsonrequest();

setuprecyclerview(lstAnime);

recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_item,menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override

if (adapter != null){
adapter.getFilter().filter(newText);}

}
});
return true;
}
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
searchView.setQuery(query, false);
}
}
}
I do filtering stuff in my adapter but since error happens here, I think there's no need to put my adapter code here and also because filtering with text works perfectly, the only problem is voice search.
That's because you are accessing a null searchView object in onNewIntent(). Create a global reference variable for searchView in your class and instantiate in onCreateOptionsMenu(). Like below:
SearchView searchView;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_item,menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
if (adapter != null){
adapter.getFilter().filter(newText);}
return false;
}
});
return true;
}
