my class extended appcompatactivity class.

my style :

 <style name="apptheme" parent="theme.appcompat.light.darkactionbar"> 

my gradle :

apply plugin: 'com.android.application'  android {     compilesdkversion 24     buildtoolsversion "25.0.0"      defaultconfig {         applicationid "***.***.***"         minsdkversion 16         targetsdkversion 24         versioncode 1         versionname "1.0"         jackoptions {             enabled true         }         // enabling multidex support.         multidexenabled true     }     buildtypes {         release {             debuggable false             minifyenabled false             shrinkresources false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     }      compileoptions {         sourcecompatibility javaversion.version_1_8         targetcompatibility javaversion.version_1_8     }     dexoptions {         javamaxheapsize "2g"         incremental true         predexlibraries = false     } } repositories {     maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }     maven { url 'https://raw.github.com/felipecsl/m2repository/master' }     //  maven { url "https://jitpack.io" }     mavencentral()  } dependencies {     compile filetree(include: ['*.jar'], dir: 'libs')     compile('com.github.florent37:materialviewpager:1.2.0@aar') {         transitive = true     }     compile 'com.android.support:appcompat-v7:24.2.1'     compile 'com.android.support:recyclerview-v7:24.0.0'     compile 'com.android.support:design:24.0.0'     compile 'com.android.support:multidex:1.0.1'     compile 'com.android.support:cardview-v7:24.0.0'     compile 'com.android.support:support-v4:24.0.0'     ... 

try this
1 . update design support library , appcompat library using sdk manager installs latest versions.
2. use appcompat theme.
3. extend activity appcompatactivity instead of activity.
4. try keep version of both libraries same

compile 'com.android.support:appcompat-v7:24.2.0' compile 'com.android.support:design:24.2.0' 

5. after these clean project , run .
