EXCEPTION DETAILS:java.lang.IllegalStateException:进程3188超出游标配额100,将使用Rom MIUI终止它

Question

我使用此代码在Sdcard上加载缩略图,设备工作正常,但是设备使用rom MIUI然后它有问题"EXCEPTION DETAILS:java.lang.IllegalStateException:进程3188超出游标配额100,将杀死它"

请帮我修理一下,谢谢.

public static Bitmap getThumbnailByPath(ContentResolver cr, String path)
        throws Exception {
    String[] projection = { MediaStore.Images.Media._ID };
    Cursor cursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            projection, MediaStore.Images.Media.DATA + "=?",
            new String[] { path }, null);
    if (cursor != null && cursor.moveToFirst()) {
        long id = cursor.getLong(0);
        return getThumbnailById(cr, id);
    } else
        cursor.close();
    return null;
}

public static Bitmap getThumbnailById(ContentResolver cr, long idPhoto)
        throws Exception {
    return MediaStore.Images.Thumbnails.getThumbnail(cr, idPhoto,
            MediaStore.Images.Thumbnails.MINI_KIND, options);
}

您必须始终关闭游标.

使用这样的东西:

Cursor cursor = ...;
try {
    if (cursor.moveToFirst())
        return getThumbnailById(cr, cursor.getLong(0));
    else
        return null;
} finally {
    cursor.close();
}
