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

在build.gradle文件中，android节点下进行配置。

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 {        release {            minifyEnabled true            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            debuggable true            signingConfig signingConfigs.release        }        debug {            signingConfig signingConfigs.release        }    }    //渠道    productFlavors {        baidu {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]        }        qihu360 {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qihu360"]        }        tencent {            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "tencent"]        }    }    sourceSets {        main { java.srcDirs = ['src/main/java', 'src/main/java/jniLibs', 'src/main/jniLibs'] }    }    //修改生成的apk名字    applicationVariants.all { variant ->        variant.outputs.each { output ->            def oldFile = output.outputFile            if (variant.buildType.name.equals('release')) {                def releaseApkName = 'pintuan_' + variant.productFlavors[0].name + '_release_' + defaultConfig.versionName + '.apk'                output.outputFile = new File(oldFile.parent, releaseApkName)            }        }    }}
