很抱歉再次击败这匹马 - 我正在测试一个在小型设备上运行完美但却无法在标签上创建或打开数据库的应用程序。该应用程序在三星S3 mini上运行良好，但我现在正在三星Tab上试用它。
相关代码段
private static String DB_PATH =＆＃34; /data/data/com.example.squashbotv2/databases /" ;; private static String DB_NAME =＆＃34; squashbot.db＆＃34 ;;
String myPath = DB_PATH + DB_NAME;
checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
