DexIndexOverflowException issue after updating to latest appcompat and support library

今天遇到这个错误：

com.android.dex.DexIndexOverflowException:
method ID notin[0,0xffff]:65536

找了好久发现了解决办法：

This message sounds like your project is too large.You have too many methods. There can only be 65536 methods for dex.Since the gradle plugin 0.14.0 and the Build Tools 21.1.0 you can use the multidex
support.Just add these lines in the

build.gradle

:

android {defaultConfig {
...// Enabling multidex support.
multiDexEnabled true
}
...
}dependencies {
compile 'com.android.support:multidex:1.0.0'
}

Also in your

Manifest

add
the

MultiDexApplication

class
from the multidex support library to the application element

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.multidex.myapplication">
<application
...
android:name="android.support.multidex.MultiDexApplication">
...
</application>
</manifest>

If you are using a own

Application

class,
change the parent class from

Application

to

MultiDexApplication

.或者：If your app uses extends the Application class add this code

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