单击Run\Debug按钮时可以自动执行命令。

adb uninstall <package_name>

- Give some name (Eg adb uninstall) and description, and type
adbin Program: anduninstall <your-package-name>in Parameters:. Make sure that the new item is selected when you click Ok in the popup window.

adb程序：和uninstall <your-package-name>参数：。确保在弹出窗口中单击“确定”时选择了新项目。
Note: If you do not have adb in your PATH environment variable, give the full path to adb in Program: field (eg /home/user/android/sdk/platform-tools/adb).
注意：如果您的 PATH 环境变量中没有 adb，请在 Program: 字段中提供 adb 的完整路径（例如 /home/user/android/sdk/platform-tools/adb）。

I am using Android Studio 2.1.2. I had same requirement as OP. Though above two answer seemed to help everyone, it did not work for me . I am sharing what worked for me.
我正在使用Android Studio 2.1.2. 我和OP有同样的要求。虽然以上两个答案似乎对每个人都有帮助，但对我来说却不起作用。我正在分享对我有用的东西。
Go to main menu/Run/Edit Configuration. Select appunder Android Applicationon the left.This should open multi-tabbed pane . Select Generaltab ( would be default), click green +sing at the bottom ( below text Before launch: Gradle -awake ...).
去main menu/Run/Edit Configuration。在左侧选择app下Android Application。这应该打开多选项卡窗格。选择General选项卡（将是默认值），单击+底部的绿色唱歌（文本下方Before launch: Gradle -awake ...）。
A drop down will appear, select Gradle-aware-makeoption. Another text box will pop up. enter :app:uninstallAllin this text box . (You can use ctrl+ spaceto use autocomplete todetermine right target without typing everything . And also helps you choose the right app name that is avaiable for you).
and set apply/ok. Relaunch your app.
将出现一个下拉列表，选择Gradle-aware-make选项。将弹出另一个文本框。:app:uninstallAll在此文本框中输入。（您可以使用ctrl+space使用自动完成功能来确定正确的目标，而无需输入所有内容。还可以帮助您选择适合您的正确应用程序名称）。并设置apply/ok。重新启动您的应用。
Note : Every time you launch your app now , this new target will try to uninstall your app from your emulator or device. So if your testing device is not available, your launc will probably fail while uninstalling but will continue to start your emulator. So Either start your emulator first, or re-lauch after first fail again ( as first launch will start emulator though uninstall fails).
注意：每次您现在启动您的应用程序时，这个新目标都会尝试从您的模拟器或设备上卸载您的应用程序。因此，如果您的测试设备不可用，您的 launc 可能会在卸载时失败，但会继续启动您的模拟器。所以要么先启动你的模拟器，要么在第一次失败后重新启动（因为第一次启动将启动模拟器，但卸载失败）。

I use an Android Studio plug-in called "adb idea" -- has a drop down menu for various functions (Uninstall, Kill, Start, etc) that you can target at any connected or simulated device. One could argue it takes me a step away from having a deeper understanding of the power of adb commands and I'd probably agree....though I'm really operating at a lower level of understanding anyway so for me it helps to have a helper. ADB Idea
我使用了一个名为“adb idea”的 Android Studio 插件——有一个下拉菜单，用于各种功能（卸载、终止、启动等），您可以将这些功能定位到任何连接或模拟的设备上。有人可能会争辩说，这让我距离对 adb 命令的功能有更深入的了解还有一步之遥，我可能会同意......尽管我的理解水平确实较低，所以对我来说有帮助一个帮手。亚行理念
