[英]A timer that will kill android app after idle for certain time?
我正在使用一項服務,該服務將檢查應用程序是否在特定時間(在后台)處於空閑狀態,並在超過指定時間后將其終止。 此外,如果用戶恢復了活動,則它將重置計時器
問題是,如果我的應用程序中很少活動,我該如何實現? 我找到了一些類似的代碼,但是如何調整它以適合我的情況? 謝謝。
示例代碼:
超時類及其服務
public class Timeout {
private static final int REQUEST_ID = 0;
private static final long DEFAULT_TIMEOUT = 5 * 60 * 1000; // 5 minutes
private static PendingIntent buildIntent(Context ctx) {
Intent intent = new Intent(Intents.TIMEOUT);
PendingIntent sender = PendingIntent.getBroadcast(ctx, REQUEST_ID, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return sender;
}
public static void start(Context ctx) {
ctx.startService(new Intent(ctx, TimeoutService.class));
long triggerTime = System.currentTimeMillis() + DEFAULT_TIMEOUT;
AlarmManager am = (AlarmManager) ctx.getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC, triggerTime, buildIntent(ctx));
}
public static void cancel(Context ctx) {
AlarmManager am = (AlarmManager) ctx.getSystemService(Context.ALARM_SERVICE);
am.cancel(buildIntent(ctx));
ctx.startService(new Intent(ctx, TimeoutService.class));
}
}
public class TimeoutService extends Service {
private BroadcastReceiver mIntentReceiver;
@Override
public void onCreate() {
super.onCreate();
mIntentReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if ( action.equals(Intents.TIMEOUT) ) {
timeout(context);
}
}
};
IntentFilter filter = new IntentFilter();
filter.addAction(Intents.TIMEOUT);
registerReceiver(mIntentReceiver, filter);
}
private void timeout(Context context) {
App.setShutdown();
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.cancelAll();
}
@Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(mIntentReceiver);
}
public class TimeoutBinder extends Binder {
public TimeoutService getService() {
return TimeoutService.this;
}
}
private final IBinder mBinder = new TimeoutBinder();
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
}
殺死應用
android.os.Process.killProcess(android.os.Process.myPid());
您可以使用handler.postDelayed(runnable,time),當您恢復活動時,可以調用handler.removeCallbacks(runnable);。 取消postDelayed
