11,042 PointsStep 2 of "Parcel All the Things"
I get the following error when I run my code.: ./TimeTravelActivity.java:15: error: incompatible types: Parcelable cannot be converted to EnergySource EnergySource source = intent.getParcelableExtra("EXTRA_ENERGY"); ^ For some reason it is not returning a EnergySource object even though as you can see in my code, I passed in the EnergySource variable with my intent. Where did i go wrong?
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
public Button goButton;
public EditText yearField;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
goButton = (Button)findViewById(R.id.goButton);
yearField = (EditText)findViewById(R.id.yearField);
final EnergySource source = new EnergySource();
goButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
Intent intent = new Intent(MainActivity.this, TimeTravelActivity.class);
intent.putExtra("EXTRA_YEAR", yearField.getText().toString());
intent.putExtra("EXTRA_ENERGY",source);
startActivity(intent);
}
});
}
}
import android.os.Bundle;
import android.view.View;
public class TimeTravelActivity extends Activity {
public String targetYear;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_time_travel);
Intent intent = getIntent();
targetYear = intent.getStringExtra("EXTRA_YEAR");
EnergySource source = intent.getParcelableExtra("EXTRA_ENERGY");
}
}

EnergySource source = (EnergySource) intent.getParcelableExtra("EXTRA_ENERGY");

16,345 PointsI don't understand why the cast is required. In the video, putting the parcelable data into Song worked without a cast. And when I put a cast on it, it says it is redundant.
Can you explain?
