Android Widget : 일정 기간이 지난 후에 업데이트되지 않습니다.

Question

얘들 아, 나는 imageview와 하나의 textview로 안드로이드 위젯을 개발했다. 그것은 잘 작동하지만 일부 업데이트 후 문자열 (따옴표) 내 외부 파일에서 메시지를 업데이트하지 않습니다. 따옴표 (메시지)가없는 이미지 만 보여줍니다. 왜 이런 일이 일어나는 걸까요? 그는 내 전체 코드입니다. 나는 초보자입니다.

Main.java

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

public class Main extends Activity { 

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


} 

UpdateWidgetService.java

public class UpdateWidgetService extends Service { 
private static final String TAG = CopyOfUpdateWidgetService.class.getSimpleName(); 

@Override 
public IBinder onBind(Intent arg0) { 
    return null; 
} 

@Override 
public void onStart(Intent intent, int startId) { 
    super.onStart(intent, startId); 

    Log.d(TAG, "onStart started"); 

    // Create some random data 
    Random random = new Random(); 

    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this.getApplicationContext()); 

    int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS); 

    if (appWidgetIds.length > 0) { 

     for (int widgetId : appWidgetIds) { 
      List<String> qList = getListFromTxtFile("quotes.txt"); 
      int nextInt = random.nextInt(qList.size()); 

      RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.widget); 
      remoteViews.setTextViewText(R.id.widget_textview, qList.get(nextInt)); 
      appWidgetManager.updateAppWidget(widgetId, remoteViews); 
     } 
     stopSelf(); 
    } 
    super.onStart(intent, startId); 
} 

public List<String> getListFromTxtFile(String txtFileName){ 

// File sdcard = Environment.getExternalStorageDirectory();

// File file = new File(sdcard,txtFileName); 

AssetManager am = this.getAssets(); 

List<String> qList = new ArrayList<String>();

    // Build the intent to call the service

    Intent intent = new Intent(context.getApplicationContext(), UpdateWidgetService.class); 
    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds); 

    // To react to a click we have to use a pending intent as the 
    // onClickListener is 
    // excecuted by the homescreen application 
    PendingIntent pendingIntent = PendingIntent.getService(
      context.getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

    remoteViews.setOnClickPendingIntent(R.id.widget_textview, pendingIntent); 

    // Finally update all widgets with the information about the click 
    // listener 
    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews); 

    // Update the widgets via the service 
    context.startService(intent); 
} 

public void onDeleted(Context context, int[] appWidgetIds) { 
    // Toast.makeText(context, "onDelete", Toast.LENGTH_SHORT).show(); 
     super.onDeleted(context, appWidgetIds);

Answer 1

어쩌면 당신은 그것을 사용 후의 BufferedReader를 닫아야합니다.

while ((line = br.readLine()) != null) { 

    Log.d("line",line); 

    qList.add(line); 
} 

br.close(); // this is what you need to add
