I am new in android developing, please help.

Thank you very much for your time and assistance in this matter.

Error:

Error:A problem occurred configuring project ':app'. Could not resolve all dependencies for configuration ':app:_debugCompile'.
Could not find com.android.support:recyclerview-v7:.

From error i can say you'll have to add the following gradle dependency :

compile 'com.android.support:recyclerview-v7:+' 

EDIT:

Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_51\bin\java.exe'' finished with non-zero exit value 1

For this error i think you are compiling JAR library twice. You are using

compile fileTree(dir: 'libs', include: ['*.jar']) 

in build.gradle file so it will compile all library that has jar extension on libs folder, so You can remove this lines:

compile 'com.squareup.picasso:picasso:2.3.2' compile 'com.nineoldandroids:library:2.4.0' compile 'com.daimajia.slider:library:1.1.5@aar' 

If issue still exists then issue is quite possibly due to exceeding the 65K methods dex limit imposed by Android. This problem can be solved either by cleaning the project, and removing some unused libraries and methods from dependencies in build.gradle, OR by adding multidex support.

defaultConfig {             // Enabling multidex support.     multiDexEnabled true } 

Did you forget the version? In your gradle config you should have something like this:

compile 'com.android.support:recyclerview-v7:23.0.1'
