无法从ApplicationAdapter调用Activity

Question

I'm starting on Android programming and right now I want to call an Activity from an ApplicationAdapter, but my code doesn't work.

I have this (ApplicationAdapter) class:

public class Render extends ApplicationAdapter implements SensorEventListener {
// ...
}

...and this (Activity) class:

public class GameOverActivity extends Activity {
//...
}

When, in the Render class I do:

Intent i = new Intent(Render.this, GameOverActivity.class);
startActivity(i);

I get this error in the first line:

"Cannot resolve constructor 'Intent(......)' "

I tried to find another solutions but none of them worked.

Can anyone help me with this problem?

Answer 1

使用context.startactivity（intent）;

Answer 2

I managed to find an answer.

In the Render class I did instance.startActivity(new Intent(instance, GameOverActivity.class)); and it worked just fine.
