Tools > Android menu doesn't exist in Android

问题:

From the docs:

To run the AVD Manager, do one of the following:

• In Android Studio, select Tools > Android > AVD Manager.
• Click AVD Manager in the toolbar.

Neither of these things exist.

I went into the settings and found the AVD Manager menu item that isn't displayed, and assigned it a keyboard shortcut, but it didn't do anything.

Other sources on the web mention running android avd to start the AVD Manager, but this was deprecated and removed.

**************************************************************************
The "android" command is deprecated.
For manual SDK, AVD, and project management, please use Android Studio.
For command-line tools, use tools\bin\sdkmanager.bat
and tools\bin\avdmanager.bat
**************************************************************************

Invalid or unsupported command "avd"

How do I open the AVD Manager?

回答1:

Just follow the prompts in the android terminal window.

I was able to fix this by trying to build the gradle and when that failed, it prompted me with "install missing platforms and sync project". This fixed the issue. It took about 5 minutes to resolve the gradle dependencies.

Note: This was trying to run an ionic application from the raw ionic generated android code. It is not initially recognized as an android project or application until you do those steps.

Until that all finished, tools>Android>menu was not available.

回答2:

The React Native CLI creates an Android project in the android directory.

In Android Studio, you can import (or open) this folder as a project, rather than the outer directory, and the Tools > Android option should appear. (It might take a few seconds for some reason.)

回答3:

Just create a new project, then you will get a gradle sync message like this:

Then click the link to install Build Tools.

And that's all

回答4:

But how would I make an existing imported project into an Android project?

Technically, AFAIK, it's the existence of apply plugin: 'com.android.application' or apply plugin: 'com.android.library' in the appropriate build.gradle file, along with the requisite setup for that in the appropriate build.gradle file. If you look at the Android project that you just created, you will see one build.gradle file in the project root directory and another in app/. The top-level build.gradle file configures where to obtain plugins (via the buildscript closure, where "closure" is "things in {}"). The apply plugin: 'com.android.application' statement in the module's build.gradle file says "this module creates an Android app", while apply plugin: 'com.android.library' says "this module creates an Android library". My assumption is that you are missing part or all of this.

The simplest solution, IMHO, would be to create a new project, then drag-and-drop the Java code and other relevant bits from the somewhat-broken project into the new one. If you drag-and-drop between two Android Studio windows, it's fairly smart, and it also honors the standard Ctrl-for-copy-vs.-move pattern (at least on Windows/Linux). This way, you are starting with a properly-configured Android project and merely adding in the code and stuff that you want it to have.

Alternatively, you can look at the new project and try to retrofit your existing project (e.g., modifying the build.gradle file(s)). An experienced developer can do this with mild difficulty; it's not the sort of thing that I would recommend to newcomers to Android.

Bump into this problem when installing Android Studio on a new machine. In my case the problem was that Intel Virtualization was not enable on BIOS.

Android Studio installed successfully but the menu option Tools->AVD Manager was not available. The problem was identified only when i try to reinstall manually Intel® Hardware Accelerated Execution Manager - Intel HAXM

The following steps were done, not all should be required for everyone:

1) Enable Intel Virtualization on computer BIOS
2) Reinstall Intel® Hardware Accelerated Execution Manager - Intel HAXM
3) Clone the project again from git
4) Synchronize gradle. Take long minutes to download all packages again.
5) Rebuild project 

Only after this steps the menu Tools->AVD Manager appear. The run option for module App also become available at this time. Before that run module was an empty box.

Note: My Android Studio Version was 3.2

I got the same problem.

Check you don't have any errors on the bottom of android studio. I got one with sdk build. If you got the same click on the link in error log.

Next go to file -> settings -> Appearance&Behavior -> Menus and Toolbars. Roll up Main menu -> Tools. Choose Android. Click on 'Applay' button and 'OK'. Wait for a while (gradel progressbar on the bottom).

I hope that I solve your problem.
