我正在使用以下意图来录制声音

Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(intent, REQUEST_RECORD_SOUND);

当代码返回到我的程序（在 onActivityResult 中）时，记录不会存储，并且 log cat 显示错误。这只发生在带有 android 2.3 版本的 Sony XPERIA 上。任何帮助将不胜感激。以下是 logcat 的输出：

我可以想到两个解决这个问题的方法。我确信还有其他人。

A. 通过捕获 SQLiteException 并对其执行某些操作（或不执行任何操作）来让插入失败。这涉及将上述步骤 2 中的 db.insert 方法调用替换为 try/catch 块内的 db.insertOrThrow。

    try {
    db.insertOrThrow(UpdateServiceDBHelper.TABLE_NAME, null, statusVals);
        } catch (SQLException ex) {
     // do something with ex or nothing
     }

简单但不太令人满意。

B. 在支持 API 8 或更高版本的 IDE 或设备上，使用 insertWithOnConflict 并明确指定冲突解决方案，而不是 insertOrThrow。

此方法调用导致冲突的行被替换。

     db.insertWithOnConflict(DBHelper.TABLE_NAME, null, insertVals, SQLiteDatabase.CONFLICT_REPLACE);

冲突也可以忽略：

     db.insertWithOnConflict(DBHelper.TABLE_NAME, null, insertVals, SQLiteDatabase.CONFLICT_IGNORE);
