Android Studio在release模式下设置debuggable

在手机上run了一个release版本的app发现不能进行debug

只能看到手机，看不到app的进程

于是想到在AndroidManifest文件设置debuggable但是却提示了这个

详细信息是

Avoid hardcoding the debug mode; leaving it out allows debug and release builds to automatically assign one less... (Ctrl+F1)
Inspection info:It's best to leave out the android:debuggable attribute from the manifest. If you do, then the tools will automatically insert android:debuggable=true when building an APK to debug on an emulator or device. And when you perform a release build, such as Exporting APK, it will automatically set it to false.  If on the other hand you specify a specific value in the manifest file, then the tools will always use it. This can lead to accidentally publishing your app with debug information.  Issue id: HardcodedDebugMode

大概意思是不要在AndroidManifest设置debuggable，如果设置了，在编译时，release模式自动会设置成false，debug模式会被设置成true。那么在哪里设置呢，思考了一下，编译相关的配置大都在gradle里面，于是去gradle文件中找了一下，就找到了buildTypes设置项

添加buildTypes->release中的debuggable属性即可

然后运行一下，就可以debug了。
