I have already looked around and everyone seems to have the same answer, move jbr to jre. But I don’t have jbr in my android studio folder. (My folder is also on E: but that isn’t a problem since everything is migrated there). What should I do?

    I had this same problem and I downloaded dolphin again and all the problems were gone.

    I had exactly the same problem.

    WORKAROUND:

    1. Browse to your Android Studio install directory in Windows Explorer
    2. Copy jrb* to jre

    You can find more details here:

    PS:

    I had a simple Flutter project that worked fine 6 months ago. When I upgraded Android Studio to Electric Eel, several things broke:

    1. A/S Electric Eel now installs its embedded Java to "jrb" instead of "jre"

      WORAROUND: copy jrb* to jre

    2. My project happened to target SDKVersion 30; Electric Eel requires minimum SDK 31

      WORKAROUND: hack your Flutter project’s androidappbuild.gradle:

       android {
   compileSdkVersion 30 => 31
   targetSdkVersion 30 => 31

    3. Electric Eel requires a newer Kotlin version

      WORKAROUND:androidappbuild.gradle:

       buildscript {
   ext.kotlin_version = '1.3.50' => '1.6.10'
