额，实际上我无法知道是什么原因导致的安装失败。。。

[CandyTek]

可以的，当手机上安装了ABC应用时，假如我尝试使用adb安装签名不一致的ABC应用到手机时，命令会返回以下错误： adb: failed to install E:\Github\ScreenTTS\app\build\intermediates\apk\debug\app-debug.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.xiaoming.screentts signatures do not match previously installed version; ignoring!]

只要判断返回的结果是否包含有 signatures do not match previously installed version（签名与以前安装的版本不匹配）这段字符串就表明此次安装失败是因为签名导致的了。
