1,330 Pointsintent.putExtra() not being accepted in challenge
I believe I am using the putExtra method correctly but I keep getting the following compiler error:
./LaunchActivity.java:25: error: 'void' type not allowed here startActivity(i.putExtra("FUEL_LEVEL", mFuelLevel)); ^ 1 error
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!
Intent i = new Intent(LaunchActivity.this, FlightActivity.class);
startActivity(i.putExtra("FUEL_LEVEL", mFuelLevel));
}
});
}
}

23,733 PointsFirst call putExtra on the intent variable, then pass the intent to startActivity(). Change your code to this:
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!
Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
intent.putExtra("FUEL_LEVEL", mFuelLevel);
startActivity(intent);
}
});
}
}

23,733 PointsEros Lombardi Yes, it is technically correct. I just created a sample app to test it and it works. I think somehow the Treehouse grading system doesn't recognize that as a correct answer.

1,330 PointsGreat! it worked. But I am still wondering why my code did not work. Technically is still correct right?
