android - 无法安装提取的辅助 dex & java.io.IOException : unable to open DEX file

Question

硬件信息

    phone: Huawei Mate 7(MT7-TL10)
    OS: Android 4.4.2
    CPU: Kirin925

构建.gradle

android {
    compileSdkVersion 27
    defaultConfig {
      minSdkVersion 15
      targetSdkVersion 25  
    }
    dependencies { 
      compile 'com.android.support:multidex:1.0.3'
    }  
}  

这里我的 minSdkVersion > 14 ，所以它支持 multidex

重要日志

提取apk二级dexes成功，但安装SecondaryDexes失败

我努力

@Override
protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     try {
         MultiDex.install(this);
     } catch(Exception e) {
         e.printStackTrace();
     }
}

但也失败了，非常感谢任何帮助。

修改你的“build.gradle”

android {
        compileSdkVersion 22
        buildToolsVersion "23.0.0"

        defaultConfig {
           minSdkVersion 14 //lower than 14 doesn't support multidex
           targetSdkVersion 22

           // Enabling multidex support.
           multiDexEnabled true
        }
  }

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