Question

我只在项目中启用 proguard 。之后，我使用调试apk 成功运行apk。

当我尝试创建已签名的Apk 时收到错误

Error:Execution failed for task ':app:proguardRelease'.
 > java.io.IOException: Please correct the above warnings first.

我的Gradle文件

apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "com.android4dev.navigationview"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:recyclerview-v7:22.1.1'
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'com.github.traex.rippleeffect:library:1.3'
compile 'com.loopj.android:android-async-http:1.4.9'
compile 'com.google.android.gms:play-services:8.1.0'

}

我尝试-dontwarn org.apache.lang.**，但仍然遇到同样的问题

请帮助我解决这个问题。

Answer 1

对于您的Google Play服务程序问题，请参阅此处com.google.android.gms.internal.zzhu: can't find referenced class android.security.NetworkSecurityPolicy

还尝试解决清单重复问题，或者可以在发布版本中禁用lint。禁用发布版本中的lint检查将此添加到build.gradle文件

lintOptions {
        checkReleaseBuilds false
    }

尝试更新build.gradle中的播放服务版本

compile 'com.google.android.gms:play-services-analytics:8.3.0'

Answer 2

根据您发布的警告日志，警告似乎来自 com.google.android.gms.internal.zzhu 包，而不是来自 org.apache。郎即可。

所以要删除警告，请在proguard-rules.pro。

中添加

-dontwarn com.google.android.**

告诉我们当时发生了什么！
