1.先参照Android Studio中创建keystore生成指定的证书文件。
2.在app/build.gradle文件中增加signingConfigs字段：如下所示：

apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.0" defaultConfig { applicationId "com.test.example" minSdkVersion 14 targetSdkVersion 21 versionCode 1 versionName "1.0" } signingConfigs { debug { File strFile = new File("../../Keystore/Debug/debug.jks") storeFile file(strFile) storePassword "storeDebug1234567890" keyAlias "debugkey" keyPassword "aliasDebug1234567890" //println strFile.absolutePath; } release { File strFile = new File("../../Keystore/Release/release.jks") storeFile file(strFile) storePassword "storeRelease1234567890" keyPassword "keyRelease1234567890" keyAlias "releasekey" // println strFile.absolutePath; } }
buildTypes { release { signingConfig signingConfigs.release runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } |
注意
1.storeFile，storePassword，keyAlias，keyPassword缺一不可，都必须填写，并且填写正确。
如果没有填写keyAlias，则签名时候会报告Android-APK signing error : Failed to read key from keystore
密码不正确的时候，会报告java.security.UnrecoverableKeyException: Cannot recover key
This exception may result from the fact that you had provided a key password that was different from the keystore password
2.对于Release配置，在buildTypes中必须指定
signingConfig
Shell
| 1 |
signingConfig signingConfigs.release |
否则，会出现
Shell
| 1 |
Error: The apk for your currently selected variant(app-release-unsigned.apk) is not signed. please specify a signing configuration for this variant(release) |
3.signingConfigs必须在buildTypes前面声明，否则会出现找不到配置选项的错误。
