Is there also a way to make the app detect when superuser permissions have been denied? Currently this code doesn’t seem to test that possibility.

Thank you Mat. I tried to modify the hosts file but not success.

String cmd = String.format(“echo %s >> /etc/hosts\n”, entry);
os.writeBytes(cmd);

Do you have any idea?
Thanks,

@WeldFire Sorry I missed your comment, I've been quite busy lately. I don't know an incredible amount about this as I never really ended up using it, but I imagine there is a way to use FileOutputStream, maybe even if you just need to turn it into a byte array (which you could then use with os.writebytes()) Deleted your comment on other post as I've answered here

Hello Mat,
You say you can use this method to “write a file into a place we do not have permission to access usually” do you have to try and copy files using os.writebytes()? or just a FileOutputStream?

How can I use this to access another applications database?

No, I think your getting confused. Mount has nothing to do with this.

A routed phone is one that has been hacked to allow root access. Your application will only work on phones that have been rooted by the user. This is obvious for security reasons.

Thanks,
‘rooted’ gets using shell command ‘mount’ ?

The root access dialog is part of the android system, but its is only avaliable if you have “rooted” the phone it is running on otherwise permission is simply denied.
