WARNING: The specified Android SDK Build Tools version (28.0.2) is
ignored, as it is below the minimum supported version (28.0.3) for
Android Gradle Plugin 3.2.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '28.0.2'" from your
build.gradle file, as each version of the Android Gradle Plugin now has
a default version of the build tools.

成功生成后，应用将在模拟器上打开 1 秒，然后出现白屏，然后关闭。然后它说应用程序停止工作。
