【问题描述】：
以下是新发布应用的崩溃报告。我用一个列为测试人员的谷歌帐户测试了购买它，这与它有什么关系吗？堆栈 strace 说路径中的包名称末尾有一个'-1'？

【问题讨论】：
-
包名有-1是正常的。你在签署apk时使用了proguard吗？
-
我没有。我看到在使用许可库时建议使用它并且我确实下载了该工具，但由于这是我的第一个应用程序，我不确定是否使用它并且认为它不是必需的？
-
这不是必需的。如果您使用过它，那可能是您的问题。在调试时，我确信它在您的设备上运行良好，但您是否尝试过在推送到 Play 商店之前安装已签名的 APK？
-
此外，此类问题通常是由于添加活动时 AndroidManifest.xml 中的错误造成的。您在那里声明您的活动时是否使用了完全限定名称？
-
精简版可在 Play 商店中使用。我添加了我的 XML
