Cannot launch AVD in emulator and Gradle won't build

Question

I created my first project on android studio2. But when I press green triangle button and create a virtual device (Nexus4) an error came:

Cannot launch AVD in emulator.

Output

Hax is enabled

Hax ram_size 0x60000000

HAX is working and emulator runs in fast virt mode.

console on port 5554, ADB on port 5555

emulator: WARNING: UpdateCheck: Failure: No error

none.xml:1: parser error : Extra content at the end of the document

emulator: WARNING: UpdateCheck: failed to get the latest version, skipping check (current version '25.1.7'6ce&amp;os=Windows&amp;version=25.1.7.0&amp;coreVersion=qemu2%202.2.0">Found</a>

I only added this code:

repositories {
    maven { url 'http://repo1.maven.org/maven2' }
}

To the android block in build.gradle(Module:app), because of another error:

(failed to resolve junit)

I also get a lot more errors at Messages Gradle Build: http://pastebin.com/3K30mApG

What is the problem and how to fix it?

Answer 1

转到app.gradle和更改buildToolsVersion到buildToolsVersion: "23.0.2"
