Question

我遵循了https://developer.android.com/studio/build/multidex

上的说明

这是我的错误代码。任务'：app：lintVitalRelease'的执行失败。

无法解析配置的所有工件
'：app：debugAndroidTestRuntimeClasspath'。找不到com.android.support:multidex-instrumentation:27.1.1。

但是我尝试获取签名的apk时遇到了同样的问题，这是我的依赖：

defaultConfig {
    applicationId "com.myproject"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
    multiDexEnabled true
}

dependencies {
 implementation project(':react-native-date-picker')
 implementation project(':react-native-wheel-picker-android')
 implementation project(':lottie-react-native')
 implementation project(':react-native-firebase')
 implementation "com.google.firebase:firebase-auth:16.0.5"  
 implementation "com.google.android.gms:play-services-base:16.0.1"
 implementation "com.google.firebase:firebase-core:16.0.4"
 implementation 'com.android.support:multidex:1.0.3'
 implementation project(':react-native-svg')
 implementation fileTree(dir: "libs", include: ["*.jar"])
 implementation 'com.android.support:design:25.4.0'
 implementation "com.android.support:appcompat- 
 v7:${rootProject.ext.supportLibVersion}"
 implementation "com.facebook.react:react-native:+"  // From node_modules
 implementation project(':react-native-navigation')
 implementation project(':react-native-linear-gradient')

}

和我的MainApplication.java：

public class MainApplication extends NavigationApplication {

  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }


  @Override
      public boolean isDebug() {
      return BuildConfig.DEBUG;
  }

   protected List<ReactPackage> getPackages() {
      // Add additional packages you require here
      // No need to add RnnPackage and MainReactPackage
      return Arrays.<ReactPackage>asList(
        new LinearGradientPackage(),
        new LottiePackage(),
        new RNFirebasePackage(),
        new RNFirebaseAuthPackage(),
        new WheelPickerPackage(),
        new DatePickerPackage()
      );

  }

  @Override
  public List<ReactPackage> createAdditionalReactPackages() {
      return getPackages();
  }

  @Override
  public String getJSMainModuleName() {
    return "index";
  }
}

感谢前进

Answer 1

删除此行

@Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }

在MainApplication.java

 implementation 'com.android.support:multidex:1.0.3'

在build.gradle

将minSdkVersion升级到21解决了我的问题

Answer 2

React-native + rnn v2遇到相同问题解决方案：如果将minSdkVersion设置为21或更高，则只需在模块级build.gradle文件中将multiDexEnabled设置为true，如下所示：

android { defaultConfig { ... minSdkVersion 21 targetSdkVersion 28 multiDexEnabled是 } ... }

但是，如果将minSdkVersion设置为20或更低，则必须使用multidex支持库，如下所示：然后按照此处的官方说明进行操作 https://developer.android.com/studio/build/multidex

找不到com.android.support:multidex-instrumentation:27.1.1
