我正在使用ant-release我的Android应用程序的一步构建.

我的build.properties看起来像这样:

application.package=xxxxx
key.store=sonr
key.alias=sonr labs
key.store.password=xxxx
key.alias.password=xxxx

当我运行ant-release时,一切都很好,除了应用程序签名.我收到错误:

-release-prompt-for-password:

-release-nosign:
     [echo] No key.store and key.alias properties found in build.properties.
     [echo] Please sign /Users/syalam/Documents/git/joeborn-sonr/sonr/bin/SONR-release-unsigned.apk manually
     [echo] and run zipalign from the Android SDK tools.

我该如何解决这个问题？

PS.我按照本教程来完成构建过程http://www.androidengineer.com/2010/06/using-ant-to-automate-building-android.html

我正在尝试使用Ant将我的Web应用程序打包到war文件中.

当我构建时,我收到以下错误:

C:\Documents and Settings\Administrator\workspace\Assignment7\build.xml:67: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre6"

以下是我的build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project name="Generate War" default="install" basedir=".">


    <property name="build.dir" value="build"/>
    <property name="dir.name" value="Assignment7"/>

我希望有一些人已经看到并解决了我现在使用的蚂蚁脚本问题.我正在使用ant脚本在eclipse中编译我的java代码,但是eclipse不断给我这些错误

我正在使用Netbeans,我已经检查了Netbeans中的Server.log和所有3个输出选项卡,用于Glassfish,Java DB数据库和我的应用程序的输出.我应该在哪里看到输出System.out.println()？我正在尝试连接到MySQL服务器,我需要看看它是否有效:)

我试图从spring应用程序发送邮件.我已经包含了所有jar文件,但是它显示了这个异常:

我有一个问题,找到算法所需的大内存量是什么意思？

就像那个和大o操作之间的区别一样？

例如

一个问题给出了以下伪代码,带有初始化的二维数组A,两个维度的大小为n:

for  i <- 1  to  n  do
       for  j <- 1  to  n-i  do
                        A[i][j]=  i + j

内存的大符号不是n ^ 2,计算也是n ^ 2吗？

我正在编写一个Scala隐式宏,它自动为case类生成一个类型类(使用quasiquote,Scala 2.10.3都带有宏天堂编译器插件和Scala 2.11.0-M7).

隐式宏以递归方式查找参数的类型类.

只要case类不接受类型参数或者在生​​成的代码中没有使用类型参数,它就可以正常工作.

但是一旦需要隐式值,<TypeClass>[<TypeParameter of case class>]调用站点的编译就会失败,并且"找不到参数e的隐含值".

以下是重现问题的代码:

trait TestTypeClass[A] {
  def str(x: A): String
}
object Test {
  implicit def BooleanTest = new TestTypeClass[Boolean] {
    def str(x: Boolean) = x.toString
  }
  def CaseClassTestImpl[A: c.WeakTypeTag](c: Context): c.Expr[TestTypeClass[A]] = {
    import c.universe._
    val aType = weakTypeOf[A]
    val TestTypeClassType = weakTypeOf[TestTypeClass[_]]
    val typeName = aType.typeSymbol.name.decoded
    val params = aType.declarations.collectFirst { case m: MethodSymbol if m.isPrimaryConstructor => m }.get.paramss.head
    val paramTypes = aType.declarations.collectFirst { case m: MethodSymbol if m.isPrimaryConstructor …

这个重构函数在Eclipse中用于包名称,对我来说很好用,直到...今天:

这是我第一次收到这个奇怪的重构错误,我不知道该怎么做:

处理重构'重命名包'时遇到异常.

原因:移动资源时遇到的问题.

单击"撤消"以撤消当前重构的所有成功执行的更改.单击"中止"以中止当前的重构.

有什么可能解释这突如其来的"心灵改变",我该如何解决？

我似乎无法理解为什么当我在quarter对象上使用println方法时,它返回toString方法的值.我从来没有调用过toString方法为什么我得到返回值？

public class Main {
    public static void main(String[] args) {
        Quarter q = new Quarter();
        Nickel n = new Nickel();
        System.out.println(q);
        System.out.println(n);
    }
}

public abstract class Money {
    private int value;

    public Money(int v) {
        value=v;
    }

    public abstract int getValue();

    protected int myValue() {
        return value;
    }

    public abstract String toString();
}

public abstract class Coin extends Money {
    public Coin(int value) {
        super(value);
        System.out.println("I am a coin, my value is " + getValue());
    }
}

这是我第一次使用Unity,我希望将它集成到现有的Android应用程序中.

根据我的阅读,您需要将Android项目打包到jar文件中.由于您无法在jar中包含资源文件夹,如何处理我的应用程序的所有资源？该应用程序还使用ActionBarSherlock和ViewPagerIndicator库,它们也拥有自己的资源.

我基本上只需要一种方法来点击Android上的按钮并弹出一个包含Unity内容的Activity.我希望应用程序的其余部分是原生Android代码.谢谢您的帮助!
