Начиная с чистого проекта, созданного с помощью:
android create project -n something -t android-7 -p something -k com.example.something -a Something
Когда я запускаю ant debug install и открываю приложение в моем эмуляторе, я вижу (как и ожидалось)
Вот где все идет плохо. Теперь я изменю что-то тривиальное в приложении. В этом примере я собираюсь удалить вызов setContentView из основного действия, чтобы он выглядел так:
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
}
}
Теперь я перестраиваю приложение с помощью ant debug install и запускаю его в эмуляторе. Я вижу это:
Это неправильно. Я только что удалил текст с моим предыдущим редактированием. Если я сделаю ant clean до ant debug install, я получу ожидаемый результат:
Я не хочу запускать ant clean перед каждым запуском ant debug install. Как я могу заставить ant на самом деле пересобрать программу без запуска ant clean каждый раз?
подробности:
Вот вывод из начального ant debug install:

Обратите внимание, что все шаги -dex, -package и -debug, кажется, думают, что я ничего не изменил.
