Question

从使用：

创建的干净项目开始

android create project -n something -t android-7 -p something -k com.example.something -a Something

当我运行ant debug install并在我的模拟器中打开应用程序时，我看到（正如预期的那样）

Emulator screenshot from initial build

这就是它变坏的地方。我现在在应用程序中改变了一些微不足道的东西。在此示例中，我将从主活动中删除setContentView调用，因此它看起来像这样：

package com.example.something;
import android.app.Activity;
import android.os.Bundle;
public class Something extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);   REMOVED
    }
}

现在我使用ant debug install重建应用程序并在模拟器中运行它。我明白这一点：

Emulator screenshot after rebuild

这是错误的。我刚刚删除了之前编辑的文本。如果我在ant clean之前ant debug install，我会得到预期的结果：

Expected result after rebuild

我不想在每次运行ant clean之前运行ant debug install。如何在不运行ant clean的情况下让ant实际重建程序？

详细信息：

以下是初始ant debug install的输出：

请注意，-dex，-package和-debug步骤似乎都认为我没有改变任何内容。

Answer 1

我刚刚降级到SDK r15 - 其中没有这样的错误。

下载仍然存在：
http://dl.google.com/android/android-sdk_r15-linux.tgz
http://dl.google.com/android/android-sdk_r15-windows.zip
http://dl.google.com/android/installer_r15-windows.exe
http://dl.google.com/android/android-sdk_r15-macosx.zip

android的bugtracker中针对SDK r16 bug最相关的问题：
http://code.google.com/p/android/issues/detail?id=23141

Answer 2

我在＃android-dev中询问过这个问题，显然sdk r16中有一个错误，它会打破步骤：

21:25＆lt; PFN＆GT;我对sdk r16确实存在问题 21:25＆lt; PFN＆GT;答案是删除classes.dex和yourapp-debug.apk 在每次蚂蚁调试之前

不幸的是，这个修复似乎不起作用所以我们似乎每次都有一个干净的构建。

Answer 3

您需要更新测试项目以反映更改，然后执行ant debug安装 1.~ / android-sdks / tools / android update test-project -m ../SampleProject/ -p ../SampleProjectTest/ 2. ant debug install

Answer 4

以下是适合我的解决方案：

将工作区复制到其他位置
删除当前工作区中的所有项目小心不要在DISK上删除
打开终端并编写以下内容 4.关闭Eclipse。
```
cd /home/user/workspace/.metadata/.plugins
rm -rf org.eclipse.core.resources
```
- 启动Eclipse
- 执行文件 - >导入
- 常规 - ＆gt;现有项目到工作区
- 单击“选择根目录”字段并浏览到工作区文件夹中的每个子文件夹，然后导入。

Ant没有使用`ant debug install`重建Android应用程序
