Android studio build.gradle配置，debug下使用正式签名，重命名apk

android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    signingConfigs {
        release {
            keyAlias 'xxx'
            keyPassword 'xxxxxxxxxxxx'
            storeFile file('./xxx.keystore')
            storePassword 'xxxxxxxxxxxxxxxx'
        }
        config {
            keyAlias 'xxxx'
            keyPassword 'xxxxxxx'
            storeFile file('./xxx.keystore')
            storePassword 'xxxxxxxx'
        }
    }

    defaultConfig {
        applicationId "com.xxx.xxxxx"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 7
        versionName "2.2.1"
        signingConfig signingConfigs.release
    }
    //配置debug模式下，使用正式版签名，此操作主要为了方便调试微信，新浪等第三方登录授权
    buildTypes {

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            debuggable true
            signingConfig signingConfigs.release
        }
        debug {
            signingConfig signingConfigs.release
