Error “Dependent package with key emulator not found” while updating Android SDK and tools

问题

I tried to update my Android Studio and got this error. How can I fix this?

I don't have much experience with Android studio and Android app development.

I am using Android Studio 2.3 and Linux.

This worked for me as this post try: Update 2 https://stackoverflow.com/a/42735118/5133603

Update 2:

Solution to emulator package issue!

After digging in the repo's XML for a while I've spotted the issue.

It turns out that the "emulator" package is only in channel 3 (canary) while the "tools" package is in channel 0 (stable) but depends on "emulator". The solution is to force the manager to download the "emulator" package from channel 3:

./sdkmanager --channel=3 emulator

Problem solved!

This is what worked for me:

1. Download the command line tools, place them in the SDK folder (e.g., on mac: /Users/user/Library/Android/sdk), and then add the bin folder to the PATH.
2. Install the latest platform: in a terminal, execute sdkmanager "platforms;android-25"
3. Open Android Studio, and go to the SDK Manager (Appearance and Behavior > System Settings > Android SDK)
4. Click on "Edit", and then select the sdk folder. Then "Next" > "Next" > "Finish".

I hope this works for you too.

Temporarily change update channel to Canary Channel (Settings > Appearance & Behavior > System Settings > Updates). It works for me (Windows, Android Studio 2.3) I hope, this bug will be fixed in the next version of Android Studio.

回答4:

1. Start "Android SDK Manager" from this path:

   %Android_home%\SDK Manager.exe
   

2. Install all updates from this manager.

P.S. This worked for me.

My solution using Void Linux (it should fix for other distributions too):

1. Create a new folder named Sdk in this exact path. Bash example: $ mkdir $HOME/Android/Sdk

2. cd to this folder, and download the latest SDK command line version. Bash example: $ curl https://dl.google.com/dl/android/studio/ide-zips/2.3.0.8/android-studio-ide-162.3764568-linux.zip

3. Extract the android-studio-ide-162.3764568-linux.zip. It must be this way: $HOME/Android/Sdk/tools

4. Launch Android Studio, and then proceed with normal installation.

PS: If you don't have a Android folder on your $HOME, you should create it, and then make the steps 1, 2, and 3, select the $HOME/Android/Sdk Folder in Android Studio → Configure → *SDK Manager → Edit, and proceed to step 4.

This is what worked:

1. Download the command line tools and place them in the SDK folder (on mac:~/Library/Android/sdk).
2. Install Android studio 2.3 (on mac: /Application/Android Studio.app)
3. Add path to java in Android Studio (export PATH=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home/bin:$PATH)
4. Set JAVA_HOME (export JAVA_HOME=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home)
5. cd to ~/Library/Android/sdk/tools/bin and execute ./sdkmanager "platforms;android-25"
6. Accept the license - this will install the android-25 platform
7. Launch Android Studio, and goto the SDK Manager. The SDK Manager will now recognize the SDK path (~/Library/Android/sdk).
8. Now install the rest of the tools.

This fixed it for me (on a fully-patched Ubuntu 16.04 (Xenial Xerus)).

Disclaimer: I cleaned up everything beforehand:

rm -Rf ~/android-studio/ ~/.AndroidStudio2.2/ ~/.android/ ~/Android/

Then:

• wget https://dl.google.com/dl/android/studio/ide-zips/2.3.0.8/android-studio-ide-162.3764568-linux.zip
• wget https://dl.google.com/android/repository/tools_r25.2.3-linux.zip
• unzip android-studio-ide-162.3764568-linux.zip -d ~/
• mkdir -p ~/Android/sdk
• unzip tools_r25.2.3-linux.zip -d ~/Android/sdk
• ~/Android/sdk/tools/bin/sdkmanager "platforms;android-25"
• ~/Android/sdk/tools/bin/sdkmanager --channel=3 emulator
• ~/android-studio/bin/studio.sh
• Click "Configure" in the launch window
• Select "SDK Manager" in the menu
• The list on the right shows "partially installed" for API level 25
• Click "Edit" on the right of "Android SDK Location"
• You get the warning "an existing Android SDK was detected wizard will only download missing or outdated SDK components"
• Click "Next"
• Click "Next"
• [wait while it installs]
• Click "Finish"

Just delete the directory C:/Users/%user%/AppData/Local/Android/sdk and rename the other directory in that location from sdk1 to sdk. Restart Android Studio (close projects) and an assistant will pop-up asking you to update the sdk which will be detected during that process, so a re-download won't be necessary.
