feat: 第三轮深度完善 — SQLite/JSON/网络/媒体/文本 真实实现
SQLite真实数据库: - SQLiteDatabase: execSQL/insert/insertOrThrow/replace/update/delete/query 用sqlite3 - 修复getVersion/setVersion用PRAGMA user_version - 修复getMaximumSize/getPageSize/setMaximumSize/setPageSize用PRAGMA - SQLiteStatement: execute/simpleQueryForLong/simpleQueryForString/execQuery - SQLiteOpenHelper: onCreate/onUpgrade/onDowngrade回调正确触发 - 修复SQLiteCursor.moveToPosition越界处理 - 修复ContentValues值对提取bug JSON真实实现: - JSONObject: isNull/append/putOnce/putOpt/getNames - JSONArray: 完整put/get/opt/length/toString 网络真实实现: - NetworkInterface: getByName/getNetworkInterfaces/getHardwareAddress 用/sys/class/net+fcntl.ioctl - InterfaceAddress: 新增类 - ConnectivityManager: getActiveNetwork/getAllNetworks 用LinuxNetwork - WifiManager: getScanResults用nmcli, setWifiEnabled用nmcli/rfkill - BluetoothAdapter: getAddress/getName 用bluetoothctl 媒体真实实现: - MediaPlayer: prepare检查文件, getCurrentPosition实时计算, getDuration/getVideoWidth用ffprobe - MediaRecorder: setVideoSize/setVideoFrameRate/setVideoEncodingBitRate配置存储 - MediaMetadataRetriever: extractMetadata用ffprobe, getFrameAtTime用ffmpeg, getEmbeddedPicture用ffmpeg 文本真实实现: - TextUtils: split用re.split, concat/indexOf/lastIndexOf/urlEncode/urlDecode - SpannableString: setSpan/getSpans/getSpanFlags/nextSpanTransition 真实实现 - SpannableStringBuilder: 修复append重载bug Provider增强: - Settings: putBoolean/getBoolean - MediaStore: getContentUri/VOLUME常量 - ContactsContract: 补全常量和CommonDataKinds Util增强: - Log: w/e/wtf支持Throwable参数, 修复wtf重复定义bug - TypedValue: 修复complexToDimension/complexToFloat/getFloat实现 修复: - __init__.py: 补全NetworkInterface/InetAddress/MediaMetadataRetriever/SpannableStringBuilder导出 统计: 221模块, 3666类, 31005方法, 183529行
