I can not compile the project gets the following error compilation:

Error:Execution failed for task ':myApp:dexDebug'.

Of course, this code solve my problem

`configurations {
 all*.exclude group: 'com.android.support', module: 'support-v4'`

but unfortunately does not satisfy me

```
dependencies {
    compile fileTree(include: '*.jar', dir: 'libs')

    compile 'com.android.support:support-v4:21.+'
    compile project(':PullToRefreshListFragment')
    compile project(':validator')
    compile project(':AndroidBootstrap')

    compile 'com.google.android.gms:play-services:6.+'
    compile 'com.android.support:appcompat-v7:21+'

    compile 'com.github.codechimp-org.apprater:library:1.0.+'
    compile 'com.sothree.slidinguppanel:library:+'
    compile 'me.grantland:autofittextview:0.2.+'
    compile 'io.realm:realm-android:0.71.0'

    compile ('com.loopj.android:android-async-http:1.4.6')
    {
        exclude group: 'com.google.android', module: 'support-v4'
    }

    compile('de.keyboardsurfer.android.widget:crouton:1.8.5@aar') {
        exclude group: 'com.google.android', module: 'support-v4'
    }

    compile ('io.nlopez.smartlocation:library:2.+')
    {
        exclude(group: 'com.google.android', module: 'gms:play-services')
    }
    configurations {
      // all*.exclude group: 'com.android.support', module: 'support-v4'

    }

```

how can I compile the project?
