Now that we can Examining sqlite3 Databases from a Remote Shell , is it possible to examine SharedPreferences from adb shell? Since it would be much more convenient to examine and manipulate SharedPreferences from command line when debugging. Or put in another way, in what files SharedPreferences are saved, and how to view and modify these files? Fine, I found the file just after I raised the question above. (It seem asking questions publicly stimulate me to search answers by myself much more diligently, since I don't want my dear peers to view me as a lazy programmer.) It is an XML file under

Currently, I have a LoginActivity that looks something like this: LoginActivity.java public class LoginActivity extends Activity implements ILoginView { private final String LOG_TAG = "LOGIN_ACTIVITY"; @Inject ILoginPresenter mPresenter; @Bind(R.id.edit_login

I'm currently taking the "Developing Android Apps" Udacity course. In the "Lesson 3: New Activities and Intents > Use SharedPreferences" segment, the instructor asked me to dig around the Android Developer site for how to get the user preferences from SharedPreferences . However, I found it different between the official documentation and the course's solution.
