我有一个用户在谷歌播放中报告的内存错误,无论我怎么努力,我似乎​​无法重现.

错误显示在我的java文件的行上,我尝试设置我的文件的布局.这是logcat的完整转储:

我一直在使用HCE并一直面临的IOException上

isoDep.connect();

在特定的Android读卡器设备cr100 simcent上.

当我使用以下标志在NFC中启用阅读器模式时,HCE工作正常.

public static int READER_FLAGS =
        NfcAdapter.FLAG_READER_NFC_A | NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK;

但有了这个,我无法阅读NDEF标签.虽然相同的代码在Nexus 7(2012)平板电脑上运行得非常好.

附上完整的代码

CardReaderFragment

public class CardReaderFragment extends Fragment implements LoyaltyCardReader.AccountCallback {

    public static final String TAG = "CardReaderFragment";
    // Recommend NfcAdapter flags for reading from other Android devices. Indicates that this
    // activity is interested in NFC-A devices (including other Android devices), and that the
    // system should not check for the presence of NDEF-formatted data (e.g. Android Beam).
    public static int …

我正在尝试编写一个查询来获取Moodle中课程文件的名称和路径,但似乎我永远无法做到这一点.以下是我现在所做的事情,对此的任何帮助都非常感谢:)

SELECT SOURCE file,
              course,
              contenthash path
FROM mdl_files
INNER JOIN mdl_context ON mdl_files.contextid = mdl_context.id
JOIN mdl_resource ON instanceid = mdl_resource.id
WHERE course=
    (SELECT id
     FROM mdl_course
     WHERE fullname="XXXX")

我试图用listview创建一个自定义对话框,它将包含复选框和textviews,我只是找不到合理的教程来做,任何帮助或提示将不胜感激.
