HttpClient was deprecated in API Level 22 and removed in API Level 23  You can still use it in API Level 23 and onwards if you must  however it is best to move to supported methods to handle HTTP  So  if you re compiling with 23  add this in your build gradle   android       useLibrary  org apache http legacy

HttpClient is not supported any more in sdk 23  You have to use URLConnection or downgrade to sdk 22  compile  com android support appcompat-v7 22 2 0    If you need sdk 23  add this to your gradle   android       useLibrary  org apache http legacy      You also may try to download and include HttpClient jar directly into your project or use OkHttp instead

You have to add just one line  useLibrary  org apache http legacy    into build gradle Module  app   for example  apply plugin   com android application   android       compileSdkVersion 24     buildToolsVersion  25 0 0       useLibrary  org apache http legacy       defaultConfig           applicationId  com avenues lib testotpappnew          minSdkVersion 15         targetSdkVersion 24         versionCode 1         versionName  1 0          testInstrumentationRunner  android support test runner AndroidJUnitRunner            buildTypes           release               minifyEnabled false             proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules pro                     dependencies       compile fileTree dir   libs   include      jar        androidTestCompile  com android support test espresso espresso-core 2 2 2             exclude group   com android support   module   support-annotations             compile  com android support appcompat-v7 24 2 1      testCompile  junit junit 4 12

in API 22 they become deprecated and in API 23 they removed them completely  a simple workaround if you don t need all the fancy stuff from the new additions is to simply use the  jar files from apache that were integrated before API 22  but as separated  jar files   1  http   hc apache org downloads cgi 2  download httpclient 4 5 1  the zile file 3  unzip all files 4  drag in your project httpclient-4 5 1 jar  httpcore-4 4 3 jar and httpmime-4 5 1 jar 5  project  right click  open module settings  app  dependencies     File dependency and add the 3 files 6  now everything should compile properly
