问题描述

重命名程序包后，我的项目在android中构建时显示错误.

After renaming package my project showing error while building in android.

我使用了以下方法: Android Studio重命名程序包重命名了我的项目，之后，它开始出现以下错误:

I used this: Android Studio Rename Package for renaming my project and after that it started getting these errors:

Error:The number of method references in a .dex file cannot exceed 64K.
Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: java.lang.UnsupportedOperationException

然后我使用了 https://developer.android.com/tools/building/multidex.html 解决第一个错误，但这也没有用.

then i used https://developer.android.com/tools/building/multidex.html for resolving first error but that also didn't work.

所以我重新启动了Android Studio，然后再次尝试构建，但是发生了相同的错误.

So i restarted Android Studio and then again tried to build but same error occured.

然后，我尝试撤消回旧的程序包名称，但没有任何反应... 请帮忙！...

then i tried to undo back to old package name but nothing good happened..... please help!...

先谢谢了……

推荐答案

首先在代码下方添加build.gradle

dependencies {//just add below one in dependency
compile 'com.android.support:multidex:1.0.0' ....//no change your old jar file.....}

然后

android {
compileSdkVersion 24
buildToolsVersion '24.0.1'
defaultConfig {
    applicationId "your pkg name"
    minSdkVersion 15
    targetSdkVersion 24
    versionCode 6
    versionName "v2.5.2.2"
    multiDexEnabled true // just add it
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {
}
dexOptions { //add it
    javaMaxHeapSize "4g"
}}

清单文件中

<application
android:name=".Education_multidex" //add what ur create java file
android:allowBackup="true"
android:icon="@drawable/rvms_education_luncher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme"> ....</application>

然后创建并添加一个Java文件，例如Education_multidex.java

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

最终构建您的应用，然后在上述java文件中添加导入一些lib
