我已经编写了在android上截图的代码，我正在尝试为此编写一个测试。运行测试方法时，我收到以下错误消息： Activity never becomes requested state "[STARTED, CREATED, DESTROYED, RESUMED]" (last lifecycle transition = "PRE_ON_CREATE") . 我很难弄清楚我做错了什么。
生产代码已经过手动测试。
我的测试代码在 src/androidTest/java/org/app :

@RunWith (AndroidJUnit4.class)
public class ScreenshotsCaptorTest {
    @Rule
    public ActivityScenarioRule<TestActivity> rule =
        new ActivityScenarioRule<>(TestActivity.class);

    @Test
    public void test() {
        // This line is never reached
        ActivityScenario<TestActivity> scenario = rule.getScenario();
        scenario.onActivity(activity -> {
            activity.setCallback(() -> {
                try {
                    Bitmap screenshot = ScreenshotsCaptorBuilder.captor.takeScreenshot();
                    // Assert screenshot is non-null
                } catch (CaptureScreenshotFailedException e) {
                    throw new RuntimeException(e);
                }
            });

            Intent intent = ScreenshotsCaptorBuilder.intent(activity);
            activity.startActivityForResult(intent, 100);
        });
    }
}

我的助手活动 src/androidTest/java/org/app :

import org.app.test.R;

public class TestActivity extends Activity {
    private Callback callback;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // This line is never reached
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
    }

    public void setCallback(Callback callback) {
        // This line is never reached
        this.callback = callback;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        // This line is never reached
        ScreenshotsCaptorBuilder.createCaptor(this, resultCode, intent);
        callback.done();
    }

    public interface Callback {
        // This line is never reached
        void done();
    }
}

这个 src/androidTest/AndroidManifest.xml 文件：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="org.app">

    <application>
        <activity
                android:name=".TestActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

以及 src/androidTest/res/layout/activity_test.xml :

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</androidx.constraintlayout.widget.ConstraintLayout>

如果有人能给我一些建议或提示来解决我的问题，那将是非常有帮助的。提前谢谢。
