Check if you have selected the right Build Variant, usually "release" comes with debuggable false
检查您是否选择了正确的 Build Variant，通常“ release”附带debuggable false
Example:
例子：
buildTypes {
release {
debuggable false
....
}
}
is not recommendable change releaseto debuggable true, just change the right variant
不推荐将发布更改为debuggable true，只需更改正确的变体
debug {
debuggable true
....
}

In My case, For some reason I disabled Instant run and it has changed the Launch value from "Default Activity" to "Nothing" in "Run/Debug configurations". So always it says "Could not connect to remote process. Aborting debug session" and I was not able to debug. I enabled Instant and changed the Launch value from "Nothing" to "Default Activity" in "Run/Debug configurations" and it worked. Hope this will help some one.
在我的情况下，出于某种原因，我禁用了即时运行，它已将“运行/调试配置”中的“启动”值从“默认活动”更改为“无”。所以总是说“无法连接到远程进程。中止调试会话”，我无法调试。我启用了 Instant 并在“运行/调试配置”中将 Launch 值从“Nothing”更改为“Default Activity”并且它起作用了。希望这会帮助某人。
(to get Run/Debug configurations, click "app" drop down and click Edit Configurations)
（要获取运行/调试配置，请单击“应用程序”下拉菜单，然后单击“编辑配置”）

By default Android Studio builds the debugversion of the application. However, during the publishing phase you may have switched to the releaseone as the tutorial suggests.
默认情况下，Android Studio 构建debug应用程序的版本。但是，在发布阶段，您可能已经release按照教程的建议切换到了那个。
ADB won't be able to attach to the application unless you revert to the debugconfiguration oryou allow to the debug the releaseone.
除非您恢复debug配置或允许调试该配置，否则 ADB 将无法附加到应用程序release。
If nothing of this works, you may resort in restarting ADB as explianed in How to restart ADB manually from Android Studio
如果这些都不起作用，您可以按照如何从 Android Studio 手动重启 ADB 中的说明重新启动 ADB
Revert to debug configuration
恢复到调试配置
- Choose Build->Select Build Variant
- Pick up
debugin the second column - Deploy the application again
- 选择Build->Select Build Variant
debug在第二列拿起- 再次部署应用程序
Allow the release version to be debugged
允许调试发布版本
- Select your application node in the tree
- Right click and choose Open Module Settings(or hit F4)
- Select Build Variantson the left
- Choose
releaseon the right - Set
debuggabletotrue - Apply and deploy the application
- 在树中选择您的应用程序节点
- 右键单击并选择打开模块设置（或按 F4）
- 选择左侧的构建变体
- 选择
release右边 - 设置
debuggable为true - 应用和部署应用程序
Keep in mind that your life won't be easy as your application may be optimized and therefore not debugger friendly (e.g. you might not be able to step in certain methods, or view some local variables).
请记住，您的生活并不容易，因为您的应用程序可能已优化，因此对调试器不友好（例如，您可能无法单步执行某些方法，或查看某些局部变量）。
