Emulator For Android 12 Preview No Connection

I have installed the Android 12 Preview emulator. I had a lot of problems because the emulator was crashing on start up but after uninstalling and installing it again and restartin

Solution 1:

Based on the issuetracker, the Android S beta 2 emulator image depends on a newer version of the emulator itself (without explicitly requiring it). The problem should be resolved by installing a newer 30.7.3 version of the emulator from the canary channel.

Update 2021-06-23: Emulator 30.7.4 is now available in the stable channel.

Solution 2:

I was able to fix this by using a couple of things.

1. Changing the Graphics option on the Android Virtual Device to Software instead of Automatic or Hardware.

2. Upgrading my system's Java version from 8 to 11.

To fix this, first check the java version installed on your system by using:

java -version

In case you see Java 8, try to install Java 11 from OpenJDK (https://jdk.java.net/archive/) and then you can add aliases like this in your ~/.bash_profile file:

export JAVA8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA11_HOME=$(/usr/libexec/java_home -v11)

alias java8='export JAVA_HOME=$JAVA8_HOME'alias java11='export JAVA_HOME=$JAVA11_HOME'

Then you can easily switch to Java 11 by using:

java11

And now try to open the emulator again. It should work.
