我一直在安卓电视台工作，可通过频道提供商进行搜索。我在通过我的应用程序搜索一些关键词时遇到了问题，比如索尼max、hbo、kantipur等。在这种情况下，不会调用查询函数。但一些关键字，如电影名、演员名工作得很好，并且正在调用查询函数。
这是我的密码，

class SearchDatabase : ContentProvider() {

    val PROVIDER_NAME = "com.genius.channelprovider"
    val URL = "content://$PROVIDER_NAME/channel_suggestion "
    val CONTENT_URI = Uri.parse(URL)

    private var db: SQLiteDatabase? = null
    val TABLE_NAME = "search"

    class DatabaseHelper internal constructor(context: Context?) :
        SQLiteOpenHelper(context, "livetv", null, 2) {
        override fun onCreate(db: SQLiteDatabase) {
            db.execSQL(
                " CREATE TABLE channel" +
                        " (${VideoDatabase._ID} INTEGER PRIMARY KEY AUTOINCREMENT, " +

我已经阅读了android文档并按照建议进行了尝试，但我找不到解决方案。
