why ? No reason NullPointer: Your space item count must be greater than 1 , your current items count isa : 0

how to fix intent ?

`spaceNavigationView.setSpaceOnClickListener(new SpaceOnClickListener() {

Fragment currentFragment = getSupportFragmentManager().findFragmentById(R.id.content);

@Override
public void onCentreButtonClick() {
Log.d("onCentreButtonClick ", "onCentreButtonClick");
//spaceNavigationView.shouldShowFullBadgeText(true);
Intent intent = new Intent(MainActivity.this,Emergency.class);
startActivity(intent);
}
`

Start by reproducing the MainActivity code around setSpaceOnClickListener and the Intent targeting Emergency, then capture the complete NullPointerException stack trace and inspect the SpaceNavigationView setup. Done means identifying the failing call, explaining the space item-count message, and verifying the corrected usage with the shown navigation flow.
