Android ArrayIndexOutofBounds仅在2部电话上出现异常

我对此应用程序有问题：

我有这个拉波特。在我朋友的电话和模拟器上一切都很好。下面是有问题的raport和class。它是一个负责4x2小部件的类

public class CountdownService extends Service {
public static final String UPDATE = "update";
public static final String PLUS = "plus";
public static final String MINUS = "minus";
public static final long  MODIFY= 86400000;
Bitmap bla[]=null;
 private static final int kDigitsViewIds[] = {
        R.id.bmp0,
        R.id.bmp1,

    };  

@Override
public void onStart(Intent intent, int startId) {
    if (bla==null){
        getDigits();
    }

    String command = intent.getAction();
    int appWidgetId = intent.getExtras().getInt(
            AppWidgetManager.EXTRA_APPWIDGET_ID);
    RemoteViews remoteView = new RemoteViews(getApplicationContext()
            .getPackageName(), R.layout.countdownwidget);
    AppWidgetManager appWidgetManager = AppWidgetManager
            .getInstance(getApplicationContext());
    SharedPreferences prefs = getApplicationContext().getSharedPreferences(
            "prefs", 0);
    int year = prefs.getInt("year", 0);
    int month =prefs.getInt("month", 0);
    int day = prefs.getInt("day", 0);

    //plus button pressed

    TimeZone tz = TimeZone.getTimeZone("GMT+1:00");
    Date date1 = new Date();
    //Calendar calendar = new GregorianCalendar(2012, 05, 8, 18 );
    Calendar calendar = new GregorianCalendar(year, month, day);
    calendar.setTimeZone(tz);
    long timme = calendar.getTimeInMillis() - date1.getTime();
    int d = (int) ((timme / 1000) / (3600*24));

    Bitmap[] bla = getDigits(); 

    String days=String.format("%02d", d);

String time = days;
char[] digits = time.toCharArray(); 

for (int i = 0; i <= 1; i++) {
    char c =digits[i];
    int a=Character.getNumericValue(c);
remoteView.setImageViewBitmap(kDigitsViewIds[i], bla[a]);

}   


    // apply changes to widget
    appWidgetManager.updateAppWidget(appWidgetId, remoteView);
    super.onStart(intent, startId);
}
public Bitmap[] getDigits(){
    if (bla == null){
        bla = prepareDigits();

        }
    return bla;
    }

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

private Bitmap[] prepareDigits() {
    int index = 10;
    Bitmap[] bla = new Bitmap[index];
    for (int i = 0; i < index; i++) {
    bla[1] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit1);
    bla[2] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit2);
    bla[3] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit3);
    bla[4] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit4);
    bla[5] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit5);
    bla[6] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit6);
    bla[7] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit7);
    bla[8] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit8);
    bla[9] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit9);
    bla[0] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit0);
    }
    return bla;
}
 }

我现在知道这是怎么回事了

 int year = prefs.getInt("year", 0);
    int month =prefs.getInt("month", 0);
    int day = prefs.getInt("day", 0);

我的默认值是0，数据是0.0.0

private Bitmap[] prepareDigits() {
    int index = 10;
    Bitmap[] bla = new Bitmap[index];
    for (int i = 0; i < index; i++) {
        bla[1] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit1);
        bla[2] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit2);
        bla[3] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit3);
        bla[4] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit4);
        bla[5] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit5);
        bla[6] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit6);
        bla[7] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit7);
        bla[8] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit8);
        bla[9] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit9);
        bla[0] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit0);
        }
        return bla;
    }
}

就个人而言，我认为你应该使用

列表

。数组是5年前的事了。

哪一行是CountdownService.java的第72行？这是最好的。。。第72行是空的…哈哈，谢谢，我从24digitalclock得到这个代码，我不知道它是怎么工作的。我纠正它：）

private Bitmap[] prepareDigits() {
    int index = 10;
    Bitmap[] bla = new Bitmap[index];
    for (int i = 0; i < index; i++) {
        bla[1] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit1);
        bla[2] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit2);
        bla[3] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit3);
        bla[4] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit4);
        bla[5] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit5);
        bla[6] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit6);
        bla[7] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit7);
        bla[8] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit8);
        bla[9] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit9);
        bla[0] =(Bitmap) BitmapFactory.decodeResource(getResources(), R.drawable.digit0);
        }
        return bla;
    }
}

Bitmap[] bla = new Bitmap[index];
bla[0] = ((BitmapDrawable)getResources().getDrawable(R.drawable.digit0)).getBitmap();
bla[1] = ((BitmapDrawable)getResources().getDrawable(R.drawable.digit1)).getBitmap();
bla[2] = ((BitmapDrawable)getResources().getDrawable(R.drawable.digit2)).getBitmap();
// etc
