AndroidStudio-Debug时使用正式签名

1. 将准备好的签名拷贝至app module下。不知道如何创建签名？在Build－Generate Signed Bundle Or apk 中 Create New
2. 在build.gradle中的android标签中添加如下代码

//设置签名，debug release运行用正式签名
    signingConfigs {
        release {
            storeFile file('talon')
            storePassword "123"
            keyAlias "talon"
            keyPassword "123"
        }

        debug {
            storeFile file('talon')
            storePassword "123"
            keyAlias "talon"
            keyPassword "123"
        }
    }

然后在buildTypes标签中引用该签名

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
        //设置Debug的签名
        debug {
            minifyEnabled false
            signingConfig signingConfigs.debug
            proguardFiles 'proguard-rules.pro'
        }
    }

3. 完整的代码如下

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.channel.project"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

 //设置签名，debug release运行用正式签名
    signingConfigs {
        release {
            storeFile file('talon')
            storePassword "123"
            keyAlias "talon"
            keyPassword "123"
        }

        debug {
            storeFile file('talon')
            storePassword "123"
            keyAlias "talon"
            keyPassword "123"
        }
    }

    buildTypes {
        //设置release的签名
         release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
        //设置debug的签名
        debug {
            minifyEnabled false
            signingConfig signingConfigs.debug
            proguardFiles 'proguard-rules.pro'
        }
    }
}
