How to access the database when developing on Android phone? [duplicate]

This question already has answers here: Debugging sqlite database on the device (17 answers) Closed 5 years ago.

I am having trouble accessing the database while I am dev开发者_开发百科eloping on the phone. Whenever I execute

cd /data/data/com.mycompck/databases

and then run ls I get: "opendir failed, Permission denied"

Or whenever I type in sqlite3 I get: "sqlite3: permission denied"

What am I doing wrong?

Are there some applications that can help me getting a human view of content resolvers values and/or SQLite databases?

Check my answer from the following thread: Why do I get access denied to data folder when using adb?

Starting from API level 8 (Android 2.2), if you build the application as debuggable, you can use the shell run-as command to run a command or executable as a specific user/application or just switch to the UID of your application so you can access its data directory.

So basically you will need to make a debug build (which is made automatically whenever you launch the application from the Android Studio unless you request the release build) and run the following commands:

run-as com.mycompck
cd /data/data/com.mycompck/databases
ls
sqlite3 ./yourdatabase.db

However note that sqlite3 binary is not present by default on many phones. Thus you will perhaps need to download it somewhere (e.g. from SuperOneClick archives at http://shortfuse.org/), save on the SD card and make it executable (which is a little bit tricky though), for example:

run-as com.mycompck
cd /data/data/com.mycompck/
cat /sdcard/sqlite3 >./sqlite3
chmod 744 ./sqlite3
./sqlite3 ./databases/yourdatabase.db

To answer the first part of your question, check out this answer. Basically, your phone needs to have root access, and you need to run adb in root mode (using "adb root").

As for the second part, I use SQLite Database Browser to view my SQLite dbs (though that's only when the db is on my computer; don't know of any on-device browsers). I don't know of any way to get a human view of content resolvers.

You have to be root to access any database file. So, you can either get root on your phone (look for information on Google) or debugging the database just from the emulator (wich gives you root access always).

Bye!

The best way to view and manage your android app database is to use this library https://github.com/sanathp/DatabaseManager_For_Android

Its a single java activity file ,just add the java file to your source folder you can view the tables in your app database , update ,delete, insert rows to you table .Everything from your app.

When the development is done remove the java file from your src folder thats it .

It helped me a lot .Hope it helps you too .

I've read up on this a little and accessing your database files for mobile seems quite of a hassle.

Take a look at this. with this you can view your database inside of your application. Database Manager

For me this worked fine. It kind of also depends on what you're planning to do ofcourse.

Hope it helps.
