android sqlite3不存在,如何添加sqlite3(需要root权限)

来源于stackoverflow

As an alternative (may not be secure or even good idea though) youcan always upload the sqlite3 binary to /system/bin this worked for me:

 First lets mount /system/ to allow read/write (rw)

 

$ adb shell

$ su

# mount -o remount,rw /system

或者mount -oremount rw /system

in another terminal change directory (cd) to where sqlite3 is andlets push it

 

$ ls

sqlite3

$ adb push sqlite3 /sdcard/

Now back to the other shell lets copy and change permissions of thebinary

# cat /sdcard/sqlite3 > /system/bin/sqlite3

# chmod 4755 /system/bin/sqlite3

Now lets mount back /system/ as read only (ro)

# mount -o remount,ro /system

And now we can use sqlite3 from shell:

# sqlite3 /data/data/com.telly/databases/fun.db

SQLite version 3.7.4

Enter ".help" for instructions

sqlite> .tables

Note: I'm using the sqlite3 binary that comes with "SuperOneClickv1.6.5-ShortFuse"

 

You can always pull sqlite3 binary from emulator:Start an emulator and then from a terminal

 $ adb pull /system/xbin/sqlite3

If you are lazy like me you can download one right here for ICS orbefore or for Jelly Bean and later here
