Android studio cannot run the command: Java – xmx1024m – CP

Today, I encountered this problem when I was running a program using Android. Gradle would make an error like this:

Can you help me?

Setting up an application development project to use multidex configuration requires some modifications to the application development project. In particular, you need to perform the following steps:

>Change your gradle build configuration to enable multidex > Modify manifest to reference the multidexapplication class

Modify your gradle build file configuration to include support libraries and enable multidex output

    android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

Read the relevant official document multidex

If your application class is extending some other classes and you don't want or can't change it, override attachbasecontext(), as follows:

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