【中文标题】当我在没有调试器的情况下方便地启动 Android Studio 应用程序时崩溃【英文标题】：Android Studio App crashes when I'm starting it on handy without debugger 【发布时间】：2017-02-11 02:58:24 【问题描述】：从昨天开始，当我在没有调试器的情况下启动应用程序时，它就会挂起。当我调试应用程序时，一切正常。我不知道我是否应该发布我认为太多的代码。 我正在使用 Google Maps API。

Java 代码只是 MainActivity，还有一些其他类，但我认为错误在 MainActivity 中，由 Google 地图引起。

【问题讨论】：
尝试检查Github 和SO question 是否可以帮助您。只需尝试遵循提供的不同解决方案即可。此外，请确保您为此项目使用 Android Studio，并尝试清理或重建项目本身。 【参考方案1】：将这些权限添加到 manifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
你很高兴..
【讨论】：
您要访问哪个文件？ 我不明白你的回答..我不想访问任何文件： 你能告诉我你在哪里得到这个错误吗？发布你的java代码 我不知道问题出在哪里！以上是关于当我在没有调试器的情况下方便地启动 Android Studio 应用程序时崩溃的主要内容，如果未能解决你的问题，请参考以下文章
