更新Android Studio 1.5後 Cannot debug application

做爲一個有強迫症和版本控的人。

Android Studio 有了新版本1.5後 立刻就更新之。。

升級後，原本的Android項目啓動不了了，控制檯輸出：

Cannot debug application xx.xxx.xxx.app on device huawei-huawei_g7_tl00.

This application does not have the debuggable attribute enabled in its manifest.

If you have manually set it in the manifest, then remove it and let the IDE automatically assign it.

If you are using Gradle, make sure that your current variant is debuggable.

提示比較明顯，要設置debuggable開關，但忘了在哪一個標籤內了。。GG

解決：

<application android:debuggable="true"></application>

加上之後AndroidManifest.xml會有紅線提示，release版本時刪掉
