FAQ по программированию под Android от новичка, и для новичков

finish();

Выход с большей вероятностью (api 15+)

Intent intent = new Intent(Activity.this, Activity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
finish();

Либо прописываем в AndroidManifest.xml — android:noHistory=«true»

Данные настройки позволяют избежать гуляния по предыдущим активностям вместо выхода.

1. В строчку public class MyActivity extends Activity дописываем implements View.OnClickListener, получается следующее:

public class MyActivity extends Activity implements View.OnClickListener {

2. Объявляем переменную Button btn;
3. В onCreate прописываем

btn =(Button) findViewById(R.id.btn);
btn.setOnClickListener(this);

4. Создаем процедуру:

public void onClick(View v) {
        // по id определеяем кнопку, вызвавшую этот обработчик
        switch (v.getId()) {
            case R.id.btn:

< uses-permission android:name="android.permission.WAKE_LOCK" />

Сам код:

PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
WakeLock wakeLock = pm.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "TAG");
wakeLock.acquire();
