build apk with gradle error

Question

To build apk with gradle, error in console as following:

if make minifyEnabled = false, error disappear. It looks like there are duplicated packages.

By the way, how to check which package is duplicated?

Answer 1

Try to add below gradle options in your build.gradle. By adding below options, you can enable MultiDex support and incremental dex support.

 ...
   defaultConfig {
      ...
      multiDexEnabled true // Enabling multidex support.
   }
    ...
   dexOptions {
     //you can speed up your builds by turning on incremental dexing
           incremental = true;
     //you can specify the heap size for the dex process
           javaMaxHeapSize "4g" 
   }

In your app extends the Application class, you can override the attachBaseContext() method and call MultiDex.install(this) to enable multidex.

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

Also you can see below related question links on stackoverflow:
