【问题描述】:
public void onCreate() {
super.onCreate();
int idFunc = getApplicationContext().getSharedPreferences(SPREF_NAME,Context.MODE_PRIVATE).getInt("idFunc", 0);
String SecKey = getApplicationContext().getSharedPreferences(SPREF_NAME,Context.MODE_PRIVATE).getString("chave", null);
Intent intent = new Intent(getApplicationContext(), ServiceEnviaClientes.class);
Bundle bundle = new Bundle();
bundle.putString("SecKey", SecKey);
bundle.putInt("idFunc", idFunc);
intent.putExtras(bundle);
PendingIntent pintent = PendingIntent.getService(getApplicationContext(), 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, Calendar.getInstance().getTimeInMillis(), 10*60000, pintent);
initImageLoader(this);
}
我正在尝试从 AlarmManager Intent 传递 SharedPrefereces 提供的额外内容并在服务中检索它,而不是在服务运行时访问我的 SharedPreferences,因为我认为这需要更多内存。
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
Toast.makeText(this,"task perform in service",Toast.LENGTH_SHORT).show();
Bundle bundle = intent.getExtras();
mIdFunc = bundle.getInt("idFunc");
mSecKey = bundle.getString("SecKey");
ThreadJSONBuild td=new ThreadJSONBuild();
td.start();
Log.d(TAG, "onStartCommand cycle, idFunc: "+mIdFunc+" , SecKey: "+mSecKey);
return super.onStartCommand(intent, flags, startId);
}
但我在mSecKey 上得到null 和在idFunc 上得到0。我不确定这是否是最佳选择,我会将 SharedPreferences 检索到 Service 的 onCreate() 方法中,但不确定。
