配置
buildToolsVersion "21.1.2"
android SDK TOOLS"24.0.2"
multidex enabled
predexLibraries =false
incremental = true
jumboMode = false
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:6.5.87'
compile 'com.google.code.gson:gson:2.3'
compile 'com.android.support:support-v4:21.0.3@aar'

}
compile 'org.java-websocket:Java-WebSocket:1.3.0'
}
如何解决这个问题？ gradlew干净，不是帮助。建立文件夹删除也不能正常工作。 Android的工作室展示在编译时没有错误。
How to solve this error? gradlew clean not helps. Build folders deletion also not working. Android studio shows no errors while compiling.
推荐答案
我有这个问题，只是找到了解决办法 - 答案是RTFM！以下是说明：<一href="https://developer.android.com/tools/building/multidex.html">https://developer.android.com/tools/building/multidex.html
I had this problem and just found the solution - answer is RTFM! Here are the instructions: https://developer.android.com/tools/building/multidex.html
Multidexing是一项新功能，因此需要一个支持库是用pre-棒棒糖设备兼容。您需要将以下添加到您的摇篮文件相关性：
Multidexing is a new feature and so requires a support library to be compatible with pre-lollipop devices. You need to add the following to your gradle file dependencies:
编译com.android.support:multidex:1.0.0
compile 'com.android.support:multidex:1.0.0'
和再multidex支持应用程序添加到您的清单：
And then add the multidex support application to your manifest:
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;舱单的xmlns：机器人=http://schemas.android.com/apk/res/android
包=com.example.android.multidex.myapplication＆GT;
＆lt;应用
...
机器人：名称=android.support.multidex.MultiDexApplication＆GT;

＆LT; /用途＆gt;
＆LT; /舱单＆GT;
<?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>
