import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class LaunchActivity extends Activity {
public Button mLaunchButton;
public int mFuelLevel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
// mFuelLevel is set elsewhere.
// Code ommitted for brevity!
mLaunchButton = (Button)findViewById(R.id.launchButton);
mLaunchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
String FUEL_LEVEL=mFuelLevel.getText.toString();
flightActivity(FUEL_LEVEL);
}
});
}
private void flightActivity(String FUEL_LEVEL)
{
Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
intent.putExtra("name",FUEL_LEVEL);
startActivity(intent);
}
}

20,145 PointsThe code challenge was to simply pass the value of the int field mFuelLevel through intent. your are doing way too much work here. in the mLaunchButton's onClick method
intent.putExtra("FUEL_LEVEL", mFuelLevel);
will get it done.
No need to create another method flightActivity and another intent object.
But if you're keen to know what went wrong here's the solution
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class LaunchActivity extends Activity {
public Button mLaunchButton;
public int mFuelLevel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
// mFuelLevel is set elsewhere.
// Code ommitted for brevity!
mLaunchButton = (Button)findViewById(R.id.launchButton);
mLaunchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
// String FUEL_LEVEL=mFuelLevel.getText.toString(); ------ No need to define the key. It's already given in challenge
flightActivity(); //------- no arguments needed.
}
});
}
private void flightActivity()
{
Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
intent.putExtra("FUEL_LEVEL", mFuelLevel);
startActivity(intent);
}
}
