Java 浓缩咖啡-无法启动intent intent{act=android.intent.action.MAIN flg=0x14000000

我正在尝试在android studio中用浓缩咖啡测试应用程序，但没有成功。我尝试了两天找到解决方案，但仍然得到了一个例外：

    ----- begin exception -----
E/TestRunner: java.lang.RuntimeException: Could not launch intent Intent { act=android.intent.action.MAIN flg=0x14000000 cmp=com.example.testoftest/.MainActivity } within 45 seconds. Perhaps the main thread has not gone idle within a reasonable amount of time? There could be an animation or something constantly repainting the screen. Or the activity is doing network calls on creation? See the threaddump logs. For your reference the last time the event queue was idle before your activity launch request was 1581611079968 and now the last time the queue went idle was: 1581611079968. If these numbers are the same your activity might be hogging the event queue.

这是我的格拉德尔：

    @Rule

    @Test
    public void view_isCorrect() {
        onView(withText("Hello World!")).check(matches(isDisplayed()));
    }

我有一台8年的笔记本电脑，装有AMD A6-3400 APU处理器。可能是这样吗？因为例如，我无法在此CPU上运行android emulator。

您是否尝试过让任何其他

ActivityTestRule

aka activity启动？您有没有用这台机器运行过任何浓缩咖啡测试？不，很遗憾，我没有。
