我开发了自己的应用程序并尝试在模拟器5556中打开它。它已成功安装。 但是当我打开它时,它会立即关闭。我希望有人能帮帮忙。 这是我的androidmainfest.xml

好吧,根据错误日志,它找不到您活动的java代码。您是否使用IDE生成活动?请确保用于您的活动的类具有相同的名称。在您的情况下,您必须在src文件夹中有一个名为Home.java的文件。你能确认它在那里吗?

更新:如果您无法让IDE为您的活动生成代码,请尝试制作一个名为Home.java的文件并尝试以下代码:

import android.os.Bundle;
import android.app.Activity;

public class Home extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.Home);
}

}

(请记住,最好的命名实践表明android中的布局名称为:全部为小写,通常以“activity”开头,而对于单词之间的空格使用“_”。这不是一个大问题,但它是良好的编码实践。好运!
