类的方法是这样的:

        try {
            Cursor cur = getApplicationContext().getContentResolver().query(
                    ContactsContract.Data.CONTENT_URI,

            if (cur != null) {

                    return null; // no photo

            e.printStackTrace();
            return null;
        }
        Bitmap bitmap = null;
        if (Build.VERSION.SDK_INT < 14) {
            Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(idContact));
            try {

            } catch (FileNotFoundException e) {
            } catch (IOException e) {
            }
        } else {
             Uri my_contact_Uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(idContact));
             InputStream photo_stream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(), my_contact_Uri, true);
             BufferedInputStream buf = new BufferedInputStream(photo_stream);
             bitmap = BitmapFactory.decodeStream(buf);
             try {
                buf.close();
            } catch (IOException e) {
            }
        }
        return bitmap;
    }

该问题已在搭载 Android 4.4 的手机上发现。在许多其他情况下，在其他操作系统版本上，该方法可以正常工作。

Answer 1

对于仍然存在此类错误问题的任何人，这是我的结论:

经过大量搜索和尝试我可以在网上找到的所有内容后，我自己修复了它。我使用DDMS 查看我的设备上当前正在运行的线程，发现有一个ASyncTask 运行了很长时间并且从未停止过。

它似乎正在访问主线程正在访问的“某物”，并且在访问该“某物”一段时间后，两个线程碰撞导致应用程序挂起，从而导致 ANR异常。

我所做的是删除 ASyncTask 并改为在应用程序开始时(当它启动时)执行此“一次性”操作，以确保它只运行一次而不会再运行。

我真的建议使用 DDMS 查看当前线程，因为 ANR 通常是由同步/并发问题引起的。ANR p>
