＆＃34; java.lang.SecurityException：注入另一个应用程序需要INJECT_EVENTS权限＆＃34;多个活动工作流测试android的错误

Question

在我的代码中，我有HomeActivity.java。在此活动中，我有3个图像按钮，当我点击任何按钮时，它会打开一个带有ItemListActivity的新活动（intent.putExtra）。

例如：

Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);)**

这里是完整的代码：

public class HomeActivityTest extends ActivityInstrumentationTestCase2<HomeActivity> {

    private HomeActivity homeActivity;
    ImageView ivFiles;
    ImageView ivForms;
    ImageView ivModels;
    private static final int TIMEOUT_IN_MS = 5000;
    private Intent mLaunchIntent;

    public HomeActivityTest() {
        super(HomeActivity.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();

        try {
            /**
             * Using ActivityInstrumentationTestCase2
             */

            setActivityInitialTouchMode(true);
            CommonUtilities.createSharedPreferenceEditor(getInstrumentation().getContext());
            homeActivity = getActivity();
            ivFiles = (ImageView) homeActivity.findViewById(R.id.ivFilesBtn);
            ivForms = (ImageView) homeActivity.findViewById(R.id.ivFormsBtn);
            ivModels = (ImageView) homeActivity.findViewById(R.id.ivModelBtn);

            assertNotNull("HomeActivity is null", homeActivity);
            assertNotNull("File Image is null",ivFiles);
            assertNotNull("File Image is null",ivForms);
            assertNotNull("File Image is null",ivModels);
        } catch (Exception e){
            e.printStackTrace();
        }
    }

    @MediumTest
    public void testOpenItemListActivity(){

        Instrumentation.ActivityMonitor receiverActivityMonitor1 = getInstrumentation()
                .addMonitor(ItemListActivity.class.getName(), null, false);

        /*
            When I click on this ivFiles in HomeActivity, it Opens new ItemListActivity.

                Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);
         */
        TouchUtils.clickView(this, ivFiles);

        ItemListActivity itemListActivity1 = (ItemListActivity) receiverActivityMonitor1
                .waitForActivityWithTimeout(TIMEOUT_IN_MS);

        assertNotNull("ItemListActivity is null", itemListActivity1);
        assertEquals("Monitor for ReceiverActivity has not been called", 1,
                receiverActivityMonitor1.getHits());
        assertEquals("Activity is of wrong type", ItemListActivity.class,
                itemListActivity1.getClass());

        assertEquals("Wrong data pass on ivFiles Click", itemListActivity1.dataToOpen, "files");

        getInstrumentation().removeMonitor(receiverActivityMonitor1);

        receiverActivityMonitor1 = getInstrumentation()
                .addMonitor(ItemListActivity.class.getName(), null, false);
        /*
            When I click on this ivFiles in HomeActivity, it Opens new ItemListActivity.

                Intent intent = new Intent(HomeActivity.this, ItemListActivity.class);
                intent.putExtra("for", "files");
                finish();
                startActivity(intent);
         */

        TouchUtils.clickView(this, ivModels);

        ItemListActivity itemListActivity2 = (ItemListActivity) receiverActivityMonitor1
                .waitForActivityWithTimeout(TIMEOUT_IN_MS);

        assertNotNull("ItemListActivity is null", itemListActivity2);
        assertEquals("Monitor for ReceiverActivity has not been called", 1,
                receiverActivityMonitor1.getHits());
        assertEquals("Activity is of wrong type", ItemListActivity.class,
                itemListActivity1.getClass());

        assertEquals("Wrong data pass on ivModels Click", itemListActivity2.dataToOpen, "models");

        getInstrumentation().removeMonitor(receiverActivityMonitor1);

    }
    }

我已为此HomeActivity编写了HomeActivityTest.java的测试用例。但是我收到了这个错误：

java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission

那么我应该如何测试这种情况？

Answer 1

如果构建服务器上的设备被锁定且屏幕无法访问，您也可以获得此信息。

Answer 2

您是否在清单文件中添加了实际权限？

这是<uses-permission android:name="android.permission.INJECT_EVENTS"></uses-permission>。
