missing manifest when using plugin in android studio - android-studio

Question

I have developed an app on eclipse and I lately started working with android studio, when I first moved the app all the dependencies were moved smoothly without any problem,
now I am trying to add the feature to share through Facebook and twitter, but for twitter whenever I try to use any plugin in the build.gradle the manifest disappears. As shown in the code below:
build.gradle (Project: project name)
The problem is in this file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
apply plugin: com.android.application
buildscript {
repositories {
jcenter()
//maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
//classpath 'io.fabric.tools:gradle:1.+'
}
}
//apply plugin: 'io.fabric'
allprojects {
repositories {
jcenter()
// maven { url 'https://maven.fabric.io/public' }
}
}
/*dependencies {
compile('com.twitter.sdk.android:twitter:1.14.1#aar') {
transitive = true;
}
}
android {
sourceSets {
main {
manifest.srcFile 'app/src/main/AndroidManifest.xml'
}
}
}*/
build.gradle (Module:app)
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '24.0.0 rc4'
defaultConfig {
applicationId "com.nwf.ICDLeKitab"
minSdkVersion 14
targetSdkVersion 14
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
}
}
}
dependencies {
compile files('libs/icu4j-4_4_2_2.jar')
compile files('libs/jsoup-1.6.3.jar')
compile files('libs/ksoap2-android-assembly-2.6.0-jar-with-dependencies.jar')
compile files('libs/zip4j_1.2.6.jar')
//compile project('com.facebook:facebook-android-sdk-4.0.1')
}
Can someone explain for me what is it happening? and how should I work with Libraries and dependencies in android studio.
Thank you

Answer 1

You are doing it wrong. Inside buildscript, there should be only a single import. Like so:
buildscript {
repositories {
maven { url 'https://maven.fabric.io/public' }
// do not add any more things here!
}
dependencies {
classpath 'io.fabric.tools:gradle:1.21.5'
// do not add any more things here, either!
}
}
If you want to import more libraries, add them inside your dependencies block.
So your updated build.gradle will look like:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
apply plugin: com.android.application
repositories {
maven { url 'https://maven.fabric.io/public' }
}
apply plugin: 'io.fabric'
buildscript {
repositories {
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'io.fabric.tools:gradle:1.+'
}
}
allprojects {
repositories {
jcenter()
// maven { url 'https://maven.fabric.io/public' }
}
}
dependencies {
compile('com.twitter.sdk.android:twitter:1.14.1#aar') {
transitive = true;
}
// replace following with your imports
compile 'com.facebook.android:facebook-android-sdk:4.5.0'
}
android {
sourceSets {
main {
manifest.srcFile 'app/src/main/AndroidManifest.xml'
}
}
}
