我从来没有遇到过这个问题。当我尝试生成已签名的apk时，请选择我的密钥库，输入文件名，它会给我一个错误。Android Studio生成已签名的apk无法在构建0.3.6 - 提供错误
不能找到的XXXX-调试unaligned.apk
我没有任何签约CONFIGS或建立各种类型的安装在我的build.gradle，因为我从来没有需要他们。我一直使用生成签名的apk，它会产生我的apk。
在从0.3.4升级到0.3.6之前，我已经注意到了，我不得不从debug/release构建变体中进行选择以使其正常工作。但那也是第一次发生。升级到0.3.6后，没有构建变体。不知道他们是如何开始的，因为我没有在build.gradle中设置任何东西。
我能够运行一个gradle assembleRelease来获取我的apk，但是如果可能的话需要生成已签名的apk。
不知道这是否是与0.3.6版本的问题，但我有固定的
走进了moduel IML文件，并改变assembleRelease到assembleDebug。你也必须改变其余的iml。这是我的。

我只是碰到了相同（或类似）的问题，显然我错过了APK_PATH选项中.iml文件： 我加入这个选项是这样的：
<?xml [...]
<component name="FacetManager">
<facet type="android" name="Android">
<configuration>
[...]
<option name="APK_PATH" value="/build/apk/<your project name>-defaultFlavor-debug-unaligned.apk" />
