Я искал в интернете несколько дней и не нашел десятков решений, ни одно из которых не работает.Поэтому я решил опубликовать свою ситуацию:
Я установил eclipse и Android.3.3.3 SDK на свой ноутбук, вставил код для hello world (или hello android) и нажал кнопку «Выполнить».Эмулятор запускается, но при выполнении действия я получаю сообщение «К сожалению! Приложение Hello Android (процесс com.example helloandroid) неожиданно остановилось. Пожалуйста, попробуйте снова»
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);
}
}
и это log cat
