Android Studio將module變爲library

進入module的build.gradle文件， 按下面的操作即可。

//apply plugin: 'com.android.application'    將此處註釋掉

添加下面這段代碼
apply plugin: 'com.android.library'   

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    useLibrary 'org.apache.http.legacy'
    aaptOptions {
        cruncherEnabled = false
        useNewCruncher = false
    }
    defaultConfig {

//        applicationId "com.maidian.financiallook"    將此處註釋掉

        minSdkVersion  rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
    }

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