hi
I work on rooted unlocked G1, latest JS firmware ADP1.5
I wrote some application that perform some root actions in the /system
of course, when messing up /system requires to remount that partition
but that's not my issue.
the code is fairly simple (attached at bottom of this message).
however when running a command as root (for example executeAsRoot("su
ls -l /system")) I get exit code 255 (i.e. -1 or failure)
when running that command as non-root - it runs ok with exit code 0.
The strange thing that this happens only in the real G1 . On the
emulator, root commands work just fine.
if i open a terminal on the G1 and perform su - I get the
"allow"/"deny" screen but after that I am able to perform actions as
root.
How can I debug the reason for the application process failure ?
private int executeAsRoot(String command) {
Process process = null;
int exitVal = -1;
try {
process = Runtime.getRuntime().exec(command);
process.waitFor();
exitVal = process.exitValue();
m_logsView.append("\nexecuted:"+command +"
->"+((exitVal==1)?
"success" : exitVal));
Log.i("executeAsRoot","Exit value is:"+exitVal);
} catch (IOException e) {
m_logsView.append("\nexecuted:"+command +"
->"+e.getLocalizedMessage
());
Log.e("executeAsRoot",e.getLocalizedMessage(), e);
} catch (InterruptedException e) {
m_logsView.append("\nexecuted:"+command +"
->"+e.getLocalizedMessage
());
Log.e("executeAsRoot",e.getLocalizedMessage(), e);
} finally {
if (process != null) {
process.destroy();
}
}
return exitVal;
}
