Answer 1

Versuchen Sie build.gradle Verdichten wie unter (entfernt doppelten Eintrag für Httpclient):

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 23 
buildToolsVersion "23.0.2" 

defaultConfig { 
    applicationId "com.example.mukesh.airpollution" 
    minSdkVersion 15 
    targetSdkVersion 23 
    versionCode 1 
    versionName "1.0" 
} 

buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 
} 

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
testCompile 'junit:junit:4.12' 
compile 'com.android.support:appcompat-v7:23.1.1' 
compile 'com.android.support:recyclerview-v7:23.1.1' 
compile 'com.google.android.gms:play-services:8.3.0' 
compile 'com.google.maps.android:android-maps-utils:0.4+' 
compile 'com.google.code.gson:gson:2.2.4' 
compile 'com.loopj.android:android-async-http:1.4.4' 
compile group: 'cz.msebera.android', name: 'httpclient', version: '4.4.1.1' 
} 

mir sagen, ob es funktioniert ?
