测试反馈安卓应用安装后闪退，通过adb安装时出现错误，而使用Android Studio安装正常。错误信息显示找不到Application。在Stack Overflow找到解决方案：关闭Android Studio的Instant Run功能。取消勾选'Enable Instant Run'后，问题解决。此问题临时解决，具体原因未深究。

事件原委：

给测试发了程序，反馈装上就闪退，我这边装的没事，又发了一次，测试还是反馈闪退，心中一万个。。。

把发给测试的程序通过adb来安装，发现确实闪退，通过android studio 安装没有问题，这你妹的。。。

把依赖库、各种clean、rebuild不行。百度查出来的跟问题的相关性也不大，最后在stackoverflow上找到了解决办法：

Android Studio->Preferences->Instant Run, uncheck "Enable Instance Run"
