没有清单属性Android Studio

Question

I imported the volley library as .jar file and I added it as a library (right click >add as library ).

When I try to run the app I get the Error

no main manifest attribute, in /Users/ervincosic/AndroidStudioProjects/AirportCab247/app/libs/library-1.0.19.jar

It doesn't seem to be connected with Volley. Clean project if that doesn't work try to remove it and compile again. To do that you can simply add dependency to your build.gradle file. You should have something like:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion ...
    ....


    dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')
        compile 'com.android.support:appcompat-v7:23.1.1'
        ...

        compile 'com.mcxiaoke.volley:library:1.+'
    }
