Manifest merger failed : uses-sdk:minSdkVersion 1

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:
uses-sdk:minSdkVersion 1 cannot be smaller than version 7 declared in    library /home/grados-sanchez/workspace/simplechat/build/intermediates/exploded-aar/com.android.support/appcompat-v7/21.0.0/AndroidManifest.xml
Suggestion: use tools:overrideLibrary="android.support.v7.appcompat" to force usage

Could you help me please

Answer 1

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.

Answer 2

It seem that you have forget to add the following code in build.gradle. add it into build.gradle and try to compile

 defaultConfig {
    applicationId "com.XXX.XXXX"  // your application package 
    multiDexEnabled true
    minSdkVersion 14
    targetSdkVersion 18
    versionCode 99
    versionName "11.1.5.5"
}

Answer 3

Just add

<uses-sdk tools:overrideLibrary="android.support.v7.appcompat"/>

to your AndroidManifest.xml and it will work. This will enable the Manifest merger to add this also when the API version is older. Don't forget to add the tools namespace at your xml root as shown below.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.app"
      xmlns:tools="http://schemas.android.com/tools">
