Question

我正在尝试为Android游戏中的特定活动编写单元测试。在每个测试中，我需要使用一个额外添加的Intent启动Activity，然后验证活动中的某个视图是否显示该Intent extra的正确内容。以下是一些代码，用于演示我正在谈论的内容：

package com.example.puzzlegame;

import android.content.Intent;
import android.test.ActivityUnitTestCase;
import android.test.suitebuilder.annotation.MediumTest;


public class GameActivityTest extends ActivityUnitTestCase<GameActivity> {

    public GameActivityTest(){
        super(GameActivity.class);
    }

    @MediumTest
    public void testViews() {
        Intent activityLaunchIntent = new Intent(getInstrumentation().getTargetContext(), GameActivity.class);
        activityLaunchIntent.putExtra("extra1", "somevalue");
        startActivity(activityLaunchIntent, null, null);

        //Ensure that views in GameActivity contain correct data, run other tests, etc.
    }

但是当我尝试运行测试时，我收到以下IllegalArgumentException。

java.lang.IllegalArgumentException: android.content.pm.PackageManager$NameNotFoundException: ComponentInfo{com.example.puzzlegame/com.example.puzzlegame.GameActivity}

}

stacktrace显示对startActivity（）的调用导致了IllegalArgumentException，但我不确定原因。有人可以帮帮我吗？提前谢谢。

首先，最重要的是你需要这样做而不是startActivity：希望这可以解决你的问题。

setActivity(launchActivity(pkg, actClass, null));

但问题仍然存在，通过添加此

来设置packageName

intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setPackage(APP_PACKAGE);
intent.setClassName(APP_PACKAGE, "your_package_name.Activity");
intent.setPackage(APP_PACKAGE);

让我知道它是否有效。
