Question

我的Android应用程序基于地图，存在于谷歌播放，用户实验崩溃当gps本地化正在搜索时似乎出现了一次。这里有2个用户发送给我的例外：

class：java.util.ConcurrentModificationException 方法：ArrayList $ ArrayListIterator.next（）

堆栈：

在模拟中它并不适用。有什么想法吗？

提前Tx。

编辑路易斯怀疑我的帖子有问题：

    public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub
    Log.d(TAG, "onLocationChanged with location " + location.toString());
    // Displays lat, long, altitude and bearing
    String text = String.format("Lat:\t %f\nLong:\t %f\nAlt:\t %f\nBearing:\t %f", location.getLatitude(), location.getLongitude(), location.getAltitude(), location.getBearing());
    this.locationText.setText(text);


    try {
        // This gets a list of addresses 
        List<Address> addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 10);
        for (Address address : addresses) {
            this.locationText.append("\n" + address.getAddressLine(0));
        }

        // Convert latitude and longitude into int that the GeoPoint constructor can understand
        int latitude = (int)(location.getLatitude() * 1000000);
        int longitude = (int)(location.getLongitude() * 1000000);

        GeoPoint point = new GeoPoint(latitude,longitude);
        mapController.animateTo(point);

    } catch (IOException e) {
        Log.e("LocateMe", "Could not get Geocoder data", e);
    }
}
}

您是否在代码中使用线程？

看起来你的一个线程试图在覆盖列表中添加一些内容，而MapView类正在迭代它以绘制它们。

您需要发布相关代码才能得到更具体的答案。

问候。
