Question

我在https://developer.android.com/training/testing/espresso/setup之后设置了意式浓缩咖啡。

第一次成功。

第二次测试失败。

我的活动中没有进度栏

重新启动，清理，重新制作，重新安装无济于事

java.lang.RuntimeException: Could not launch intent Intent { act=android.intent.action.MAIN flg=0x14000000 cmp=com.rox.espressodemo/.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 1559116009599 and now the last time the queue went idle was: 1559116010899. If these numbers are the same your activity might be hogging the event queue.

我在这里找到了解决方案。 https://stackoverflow.com/questions/57646699/android-instrumental-test-running-on-emulator-but-not-on-real-device 转到手机开发人员设置，然后关闭MIUI优化，电池优化等优化功能。然后重新安装您的应用。
