android - minifyEnabled true 在调试和 Release模式下不起作用

Question

我无法在调试和 Release模式下使用 minifyEnabled true 运行 apk。我引用了下面的链接，但没有一个对我有用。

1. Android- Error:Execution failed for task ':app:transformClassesWithDexForRelease'

2. Error converting bytecode to dex: Cause: java.lang.RuntimeException: Exception parsing classes - Android studio 2.0 beta 6

下面是我的应用程序 build.gradle 文件

apply plugin: 'com.android.application'

        vectorDrawables.useSupportLibrary = true
    }
    sourceSets.main {
        jni.srcDirs = [] //disable automatic ndk-build call
        jniLibs.srcDir 'src/main/libs' //integrate your libs from libs instead of jniLibs
    }
    dexOptions {

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 5120 MB.
To do this set org.gradle.jvmargs=-Xmx5120M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

过去 3 天我一直在工作。请帮我解决这个问题。提前致谢

Answer 1

First of all add multiDexEnabled to true

defaultConfig {
        minSdkVersion 15  // it will work fast
        targetSdkVersion 26
        multiDexEnabled true
    }

并添加依赖项，例如

dependencies {
  compile 'com.android.support:multidex:1.0.3'
}

确保创建一个扩展应用程序类，例如

 <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>

MultiDexApplication.class

public class MultiDexApplication extends Application {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}

注意:请确保将您的 gradle 和库升级到最新版本..

转到 gradle.properties 并增加堆大小。我认为您的 RAM 小于 8 GB。
