Can't use google maps

Question

I was trying to use google map in my app, but I keep getting this error:

Error:Execution failed for task ':app:preDexDebug'.
> com.android.ide.common.process.ProcessException:             org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1

I tried cleaning and restarting the project, but it didin't work either. The same project worked well on my friend's PC, but it just doesn't work on mine!

this the gradle messages content:

and that's the build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "com.example.win7.mapapp"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.google.android.gms:play-services:9.2.0'
}

and this my MapsActivity.java code:

    package com.example.win7.mapapp;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
    }







    @Override
    public void onMapReady(GoogleMap googleMap) {
        googleMap.addMarker(new MarkerOptions()
                .position(new LatLng(0, 0))
                .title("Marker"));
    }
}

If you only need Maps, then you really should just use the maps dependency, not every single Google play service — OneCricketeer, Sep 11 '16 at 22:45

The important part of all that gradle output is

Unsupported major.minor version 52.0

This means you have the incorrect version of the JDK installed. Update your installation.

For clarification, Java 7 is being used, but Java 8 is needed – OneCricketeer Sep 11 '16 at 22:47

Build Tools version 24.0.2 requires Java 8.

The easiest fix would be to continue using Java 7 and change your Gradle to use Build Tools rev 23.0.3:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.example.win7.mapapp"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Make sure it's installed as well:
