4.1中的java.lang.NoClassDefFoundError和在Android studio中使用5.1.using multidex
作者：互联网
我从3天开始就遇到了一个非常愚蠢的问题但仍然没有运气.
我正在使用Parse.com进行注册并登录.我也使用Twitter和facebook.
我的应用程序类oncreate方法： –
public void onCreate() {
super.onCreate();
Parse.initialize(this, AppConstants.PARSE_APP_ID, AppConstants.PARSE_CLIENT_KEY);
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
FacebookSdk.sdkInitialize(getApplicationContext());
}
}
我的gradle构建： –
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
useLibrary 'org.apache.http.legacy'
defaultConfig {
applicationId "rsi.com.componentsdemo"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
multiDexEnabled true
}
dexOptions {
incremental true
javaMaxHeapSize "2048M"
jumboMode = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}}dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.google.android.gms:play-services:8.3.0'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'org.apache.httpcomponents:httpmime:4.3'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.facebook.android:facebook-android-sdk:4.2.0'
compile('org.twitter4j:twitter4j-core:4.0.1') {
exclude group: 'com.google.android', module: 'support-v7'
}
compile project(':lib')
compile files('libs/Parse-1.11.0.jar')
}
我在libs文件夹中使用parse 1.11.0.jar lib.
现在问题是在Android 5.0.1设备中运行相同的代码但在4.1.1版本中崩溃了.
LogCat如下： –

请帮我解决这个问题.谢谢！！
解决方法:
如果你使用incremental = true意味着多个dex选项是启用&像4.1这样的较低设备的东西不起作用(AFAIK它不会在4.4以下工作)
因为multiple dex file
对于4.4以下的设备,我面临同样的问题.问题不在于ParsePlugin.
解决我在build.gradle中给出的问题
dexOptions {
incremental true
// here heap size give 4g i got this thing from https://groups.google.com/forum/#!topic/adt-dev/P_TLBTyFWVY
javaMaxHeapSize "4g"
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
// your dependencies which you are using.
}
整个build.gradle
apply plugin: 'com.android.application'
repositories {
mavenCentral()
}
configurations {
// all*.exclude group: 'com.android.support', module: 'recyclerview-v7'
}
android {
signingConfigs {
/*
releasebuild {
keyAlias 'hellotest'
keyPassword 'hellotest'
storeFile file('path to keystore')
storePassword 'hellotest'
}
*/
}
compileSdkVersion 'Google Inc.:Google APIs:22'
buildToolsVersion '23.0.0'
/* if you got error regarding duplicate file of META-INF/LICENSE.txt from jar file
packagingOptions {
exclude 'META-INF/LICENSE.txt'
}
*/
dexOptions {
jumboMode = true
incremental true
// here heap size give 4g i got this thing from https://groups.google.com/forum/#!topic/adt-dev/P_TLBTyFWVY
javaMaxHeapSize "4g"
}
defaultConfig {
multiDexEnabled true
applicationId "com.myapp.packagenme"
minSdkVersion 17
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.releasebuild
}
debug {
signingConfig signingConfigs.releasebuild
}
}
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
// your dependencies which you are using.
}
在Application类中,我扩展了MultiDexApplication
public class MyAppClass extends MultiDexApplication{
@Override
protected void attachBaseContext(Context newBase) {
MultiDex.install(newBase);
super.attachBaseContext(newBase);
}
}
