Updating Android Studio to version 0.4.0. nothing works! Which fixes?

问题

I've made some waste code. After some mistakes I checkout latest commit. I expected to restart with any without any hitch. But building project now I receive the message:

Waiting for device.
Target device: samsung-gt_i8190n-47900693715f5036
Uploading file
local path: /Path/to/file.apk
remote path: /path/to/file/com.example
Local path doesn't exist.
(* I've removed complete local and remote path in this post ...)

Thus, when I try to sync project with gradle files, a new message from editor arrives:

Failed to refresh Gradle project 'NutriMondoProject'
Project is using an old version of the Android Gradle plug-in.
The minimum supported version is 0.7.0.
Please update the version of the dependency 'com.android.tools.build:gradle'
    in your build.gradle files.
Search in build.gradle files

I feel like a fish out of water.

You have updated to Android Studio 0.4.0

it requires gradle plugin 0.7.+ and gradle-wrapper 1.9.

Change your build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}

Then change your gradle-wrapper.properties:

distributionUrl=http\://services.gradle.org/distributions/gradle-1.9-all.zip

Then sync your project with gradle files. Launch gradlew clean to clean your build.
