android - Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 7

Question

I'm studying this Building Simple Chat Client with Parse and I'm using gradle 2.4 to build my project. My build.gradle and AndroidManifest.xml codes are:

build.gradle

 buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.3'
    }
 }

 apply plugin: 'com.android.application'

 android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
 }


 repositories {
    jcenter()
 }


 dependencies {
    compile fileTree(dir: 'libs', include: 'Parse-*.jar')
    compile 'com.parse.bolts:bolts-android:1.+'
 }

 dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.android.support:support-v4:21.0.0'
    compile 'com.android.support:appcompat-v7:21.0.0+'    
    compile 'com.squareup.picasso:picasso:2.5.0'
 }

AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application android:label="@string/app_name" 
android:name="main.java.org.hello.ChatApplication">
    <activity
        android:name=".ChatActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

I'm getting the next error:

/home/grados-sanchez/workspace/simplechat/src/main/AndroidManifest.xml:0:0   Error:

Could you help me please

You have to add the minSdkVersion to your build.gradle.

Otherwise, gradle uses the default value = 1.
You are using a library with minSdk=7, then you can't use minSdk=1.

Also pay attention that gradle overrides the values in the Manifest.

Add something like this:

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 14  
        targetSdkVersion 22
    }
}

Pay attention to your build.gradle. You have two dependencies blocks. You have to merge these blocks.
