dex

在Android开发过程中都避免不了要集成第三方的项目、集成完之后今天碰到这个令人我非常不开心的transformClassesWithDexForDebug Exception、详细的Log如下： Error:java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex 1 2 或者会出现如下的异常: Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. > java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex 1 2 ###查阅了好多资料和别人的一些解决方法，如： ##1、第一种: defaultConfig { ... minSdkVersion 14 targetSdkVersion 21 ... //Enabling multidex

About the Title "classes of the same package" means classes that share the same package access. Please pay attention to the fact that class a.b.c.Foo doesn't have package access to class a.b.Bar . Because the latter can't access to the former if the former's modifier is default. Problem If I split two classes in the same packages into two dex files, even though I load them correctly, I will also get some error while running, the logcat likes: I/dalvikvm( 6498): DexOpt: illegal method access (call Lcom/fish47/multidex/Foo;.isWholeWord (Lcom/fish47/multidex/Foo;)Z from Lcom/fish47/multidex

类加载器 前言 Android的Dalvik/ART虚拟机如同标准JAVA的JVM虚拟机一样，在运行程序时首先需要将对应的类加载到内存中。因此，我们可以利用这一点，在程序运行时手动加载Class，从而达到代码动态加载可执行文件的目的。Dalvik/ART虚拟机虽然与JVM虚拟机不一样，ClassLoader具体的加载细节不一样，但是工作机制是类似的，也就是说在Android中同样可以采用类似的动态加载插件的功能. ClassLoader分类 下面我们简单写一个Demo来看下ClassLoader有哪些 源码如下： package org.professor.classloaderdemo; import android.content.Context; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.widget.ImageView; public class MainActivity extends AppCompatActivity { @ Override protected void onCreate(Bundle savedInstanceState) { super.onCreate

###一. Android中ClassLoader的种类 Android的ClassLoader与Java的ClassLoader基本是一一对应的。如果对Java的ClassLoader不是很了解，可以参考《【Java 虚拟机】类加载器》。 BootClassLoader（Java的BootStrap ClassLoader） 用于加载Android Framework层class文件。 PathClassLoader（Java的App ClassLoader） 用于加载已经安装到系统中的apk中的class文件。 DexClassLoader（Java的Custom ClassLoader） 用于加载指定目录中的class文件。 BaseDexClassLoader 是PathClassLoader和DexClassLoader的父类。 ###二. Android中ClassLoader的特点 遵循双亲委派模型 ClassLoader在加载一个class文件时：会询问当前ClassLoader是否已经加载过子类，如果已经加载过则直接返回，不再重复加载。如果没有加载过，会去查询当前ClassLoader的parent是否已经加载过。 因为遵循双亲委派模型，Android中的classLoader具有两个特点： 类加载共享 当一个class文件被任何一个ClassLoader加载过

I have an android application that only has one jar import which is 4 mb in size (Symja https://code.google.com/p/symja/ ) Literally the only code in the project is creating a new textview and setting it as the content view. But I am getting the error(s): Conversion to Dalvik format failed: Unable to execute dex: Java heap space Unable to execute dex: Java heap space I have another android project which is alot bigger, almost 20,000 lines of code and it runs in seconds. My eclipse.ini has the following settings: -Dosgi.requiredJavaVersion=1.5 -XX:MaxPermSize=512m -Xms512m -Xmx1024m I do not

This is a recently problem with the new SDK for Android. Now Android SDK uses the ANT convention when import external jars to the apk package, the external jars must be on the "lib" folder and the SDK ever will export the jars from that folder. My problem is when i add my jars and run my project i get this message: trouble processing "javax/transaction/HeuristicCommitException.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library. This is often due to inadvertently including a core library file in your application's project, when using an

I want to use Android L compat libs. after adding the relevant code to gradle, I get the error: Error Code: 2 Output: objc[36290]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

I got an error in the build server when sending an Android build during the dex phase. Googling a bit I learned that there is a hard limit of 64K functions (including all libs, the heaviest is google play services), or you can use the multiple dex mechanism. How do I activate this for Codename One? I understand Codename One uses Ant and as far as I understand this only works for gradle. FYI this is the workaround, that splits google play services into sub libraries with native android: http://android-developers.blogspot.com.es/2014/12/google-play-services-and-dex-method.html I had a very

I lost the code from all the apps I built last year (thunder against my hard disk, no backup for any app). As they were rather simple apps, I put them under reverse engineering process. I have already done this a dozens of time in the past, each time I had no problems at all (if we do not count hours of work to put together all the files into a single project). I have already finished 3 apps I lost during hard disk burnout. They were reversed almost flawlessly, but I got stuck with this one. Let's get in details. The reverse engineering process went well. I was able to get the XML code from
