I am writing an Android application using SQLite. How to view the .db file that's on the device without rooting it? I tried Questiod SQLite Manager but "data/data/(my application name)/.db"
The OSSP uuid tool can decode UUIDs of all versions. On Debian-based Linux systems you can use apt-get install uuid to install it; for other distributions, the package name might be different. To decode a UUID, use the -d (decode) flag: uuid -d AAAAAAAA-BBBB-CCCC-DDDD-FFFFFFFFFFFF For version 1 UUIDs, this gives the MAC address and timestamp -- since that's what's in a v1 uuid.
The other thing to try is if you have access to the program that generated this file, there may be DLL's or EXE's from the database software that may contain meta information about the dll's creator which could give you a starting point for looking for software that can read the file outside of the program that originally created the .db file.
41 Take a look at the documentation for android.database.sqlite.SQLiteDatabase. In particular, there's an openDatabase () command that will access a database given a file path.
I've worked on a number of database systems in the past where moving entries between databases would have been made a lot easier if all the database keys had been GUID / UUID values. I've considered
I found the file with .db extension in /data/data path of an application I loaded on the emulator, but I cannot open it. Is there any method to open this?
Open Device File Explorer via View > Tool Windows > Device File Explorer Go to data > data > PACKAGE_NAME > database, where PACKAGE_NAME is the name of your package (it is com.Movie in the example above) Right click on the database and select Save As.... Save it anywhere you want on your PC. Now, open the SQLiteBrowser you installed.
Объясните пожалуйста русским языком, что такое uuid, читал и википедию и другие источники, все равно не особо понимаю. Например при переходе по url posts/1 мы получим саму статью. А с использован...
sqlite3 data.db I cannot figure out how to open a database file from within the tool after having invoked it without supplying the file as a command-line argument (if I, say, double-click sqlite3.exe in Windows). What is the command within the SQLite shell tool to specify a database file?
For large volumes of small records, storing UUIDs as strings will take up a disproportionate amount of storage - it probably isn't optimal for indices either. I expect you could do better by storing 128-bit (16-byte) blobs, using a similar technique, but with bitwise operators to create valid UUID v4 bits - and then convert to/from formatted strings in your client layer.
