Requesting root access for android app -

Requesting root access for android app -

i know there questions here, tried answers given without success.

there's simple checkboxpreference (titled "root"):

<checkboxpreference android:key="root" android:title="@string/root" android:summary="@string/root_summary" android:defaultvalue="false" />

now need set onpreferencechangelistener on , gain root access. if checkbox should checked, otherwise should not:

public class settings extends preferenceactivity implements onpreferencechangelistener { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); addpreferencesfromresource(r.xml.settings); findpreference("root").setonpreferencechangelistener(this); } @override public boolean onpreferencechange(preference preference, object newvalue) { string key = preference.getkey(); if ("root".equals(key) && !((checkboxpreference) preference).ischecked()) { seek { process p = runtime.getruntime().exec("su"); p.waitfor(); log.d("settings", integer.tostring(p.exitvalue())); if (p.exitvalue() == 255) { log.d("settings", "###no root###"); homecoming false; } } grab (exception e) { log.d("settings", "###no root###"); log.d("settings", e.getmessage()); homecoming false; } log.d("settings", "!!!root!!!"); } homecoming true; } }

superuser prompts correctly root access. denying returns true, exitvalue 1 (???) , allowing freezes whole app (i guess @ p.waitfor).

i'm running superuser 3.1.3 su binary 3.1.1 (newest versions).

taking logcat can see next message: activity pause timeout activityrecord{42c0ebb8 com.example/.gui.settings}

the command you're running su will, suspect, run shell superuser. you're waiting (indefinitely) shell finish.

you need specify su some-command-here-which-needs-to-run-as-root.

unfortunately, there no way accomplish superuser permissions java code within android project. root-ness applies commands spawned su itself.
