当我运行下面的代码时，我在日志cat中没有得到任何错误，并且appstops with PACKAGE INSTALLER已经停止..我现在有点困惑，我明白我被一些愚蠢的东西卡住了。如果有人能帮我解决这个问题，我会很高兴。基本上，你需要申请的唯一权限是短信权限（互联网不是一个危险的权限，你不必向用户申请）。谷歌建议你在使用权限之前先申请权限，而不是一次申请所有权限（比如第一次启动应用程序时）。谷歌还在其开发人员文档中提供了关于如何最好地实现以及何时实现的详细信息，这在这里很难总结。查看代码的详细信息，以及如何根据应用的情况最佳地实施
如果您需要有关权限的更多详细信息或任何其他问题，请告诉我。我非常感谢您的帮助。谢谢你。我已经添加了权限请求代码。但是在授予许可时有一个错误。如果你能帮我消除这个错误，我会很高兴的。我已上载上述详细信息。请尝试将您的权限移动到应用程序标记之外
