安卓工作室Apk未签署调试变体

Question

Gradle 1.5

我将在四个具有不同屏幕的模拟器中启动我的游戏。

它适用于2个仿真器，并且在2个仿真器中它不起作用。

Android studio会提示一条消息：

Installation failed since the APK was either not signed, or signed incorrectly.
If this is a Gradle-based project, then make sure the signing configuration is specified in the Gradle build script

控制台中的错误：

pkg: /data/local/tmp/com.darwins.cubegame
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]


Installation failed since the APK was either not signed, or signed    incorrectly.
If this is a Gradle-based project, then make sure the signing configuration is specified in the Gradle build script.

我正在调试变种，所以它应该用调试密钥存储区签名（它在2个模拟器中完成），但它不在另外2个。

任何解决方法，或任何可以调查的提示？

所有（普通仿真器）同时打开

Gradle文件
