Having Trouble with SharedPreferences

So.. I stayed up all night and finally got XSharedPreferences to work with my module. But today when I tried to add other elements such as a Navigation Drawer, and have the preference page only show when tapped, it stopped working.
This is the MainActivity code that has been working just fine.
Working:
Code:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null)
getFragmentManager().beginTransaction().replace(android.R.id.content, new PrefsFragment()).commit();
}
public static class PrefsFragment extends PreferenceFragment {
@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getPreferenceManager().setSharedPreferencesMode(MODE_WORLD_READABLE);
addPreferencesFromResource(R.xml.prefs);
}
}
}
Below is the code where it stopped working. I tried back tracking and only with the code above does it work.
Not working:
Code:
public class MainActivity extends AppCompatActivity implements NavigationDrawerCallbacks {
/**
* Fragment managing the behaviors, interactions and presentation of the navigation drawer.
*/
private NavigationDrawerFragment mNavigationDrawerFragment;
private Toolbar mToolbar;
@Override

mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);

getFragmentManager().findFragmentById(R.id.fragment_drawer);
// Set up the drawer.
mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
// populate the navigation drawer
mNavigationDrawerFragment.setUserData("John Doe", "[email protected]", BitmapFactory.decodeResource(getResources(), R.drawable.avatar));

Well.. seems like moving the code that worked to its own activity and the following to the mainactivities oncreate has done the trick.
Code:
pref = getSharedPreferences(getPackageName() + "_preferences", MODE_WORLD_READABLE);

I am unable to get XSharedPreferences to work and the standard shared preferences work perfectly. I create a shared preferences file elsewhere in the application. The file is in the shared_pref folder and I can read the file which is perfectly OK.
However, I cannot make the XSharedPreferences work, I. e. I have the opposite problem.
Therefore, can I ask you to provide the code or a guidance how to make the XSharedPreferences work, so I can read the file inside of the Xposed module? In case you do not want to publish anything in this topic, can you please, send a message?

[Q] How to update a textView every second.

I have a textview that shows your amount of money and i would like the ui to update every second to visually show how much money you have in real time. Would i be able to accomplish this with a timer?, and if so what would it look like.

Hello,
You should do inside your class, outside of any method:
Code:
TextView tv;
String calculatedString;
MyAsyncTask mAsync = null;
Timer timer = null;
TimerTask task = null;
private class MyAsyncTask extends AsyncTask<String, Void, String> {
public MyAsyncTask(){
}
@Override
protected String doInBackground(String... params) {
//Background operation in a separate thread
//Write here your code to run in the background thread
//calculate here whatever you like
calculatedString = ....;
return null;
}
@Override
protected void onPostExecute(String result) {
//Called on Main UI Thread. Executed after the Background operation, allows you to have access to the UI
tv.setText(calculatedString);
}
@Override
protected void onPreExecute() {
//Called on Main UI Thread. Executed before the Background operation, allows you to have access to the UI
}
}
inside the onCreate after super and setContentView:
Code:
tv = (TextView) findViewById(R.id.tv); //your tv id here
final Handler handler = new Handler();
timer = new Timer();
task = new TimerTask() {
@Override
public void run() {
handler.post(new Runnable() {
public void run() {
MyAsyncTask mAsync = new MyAsyncTask();
mAsync.execute();
}
});
}
};
timer.schedule(task, 0, 1000); //Every 1 second
If you still need help, feel free to ask

I have attached 2 screenshots showing the errors i was given after inputting. Any idea how to fix this?

Hello,
For the first image:
You have to import the AsyncTask.
add this
Code:
import android.os.AsyncTask;
with the other imports in your java file.
For your second image:
You haven't wrote the line
Code:
setContentView(R.layout.activity_main);
under your super.onCreate(savedInstanceState); and then the code I said above (I said that on my post )
inside onCreate, where activity_main is your xml layout. And you should have inside that layout, a TextView with an id "tv" (or whatever you like)
and then:
Code:
tv = (TextView) findViewById(R.id.tv); //your tv id here
R.id.tv must much the id you have in your layout. Replace it with the actual id of your TextView. If your id is "tv", write R.id.tv, if it is "mytv" write R.id.mytv. ( I said that on my post also)
Can you show your layout file? (XML - your activity_main.xml). You said that you have a TextView Where is your TextView?

Ok I fixed the problems stated and now only have these two errors remaining

Have you imported this?
Code:

If so, change it to

Im not at the computer but I think that should solve my issue I will keep you updated

Black screen and app shutdown when trying to go back to the previous activity/view

istream.close();
}
} catch (IOException e){

}
}
public void resume(){

gameloop = new Thread(this);
gameloop.start();
}
public void pause(){
running = false;
while (true){
try {
gameloop.join();
}
catch (InterruptedException e){}
}
}
@Override public void run (){
while (running){
if (!surface.getSurface().isValid())
continue;
Canvas canvas = surface.lockCanvas();
canvas.drawColor(Color.rgb(85, 107, 47));
canvas.drawBitmap(incect[frame], 0, 0, null);
surface.unlockCanvasAndPost(canvas);
frame++;
if (frame > 1) frame = 0;
try {
Thread.sleep(500);
} catch (InterruptedException e){
e.printStackTrace();
}
}
}
}
}
I dont get any error message in the log, what i do get is about 13 messages saying "suspending all threads took: X ms" so it has something to the with my gameloop Thread i think. Unfortunately i dont see what the problem is in my code... Can anyone help me with this?

Using Intent(send mail) in Navigation drawer

I want to send mail from Navigation Drawer using the intent. First, my MainActivity.
Code:
else if(id==R.id.nav_mail) {
fragment = new MailFragment();
}
and MailFragment.
Code:
public class MailFragment extends Fragment {
public MailFragment() {
Intent email = new Intent(Intent.ACTION_SEND);
email.setType("plain/text");
String[] address = {"********@gmail.com"};
email.putExtra(Intent.EXTRA_EMAIL, address);
email.putExtra(Intent.EXTRA_SUBJECT, "Subject___****");
email.putExtra(Intent.EXTRA_TEXT, "Text___****.\n\n");
startActivity(email);
}
// @Override
// public View onCreateView(LayoutInflater inflater, ViewGroup container,
// Bundle savedInstanceState) {
// TextView textView = new TextView(getActivity());
// textView.setText(R.string.hello_blank_fragment);
// return textView;
// }
}
Run to create crash. The reason why I used to use fragment is because I made the simple screen change function fragment.
If you need more code, comment plz.

I didn't get what you are trying to do. If you are trying to invoke the "Select your mail app" screen and then send a message thru the Intent all of this when the user clicks on a row on the drawer then you should just copy the code to
Code:
else if(id==R.id.nav_mail) {
// here
}
without switching any fragment.
By the way, as far as I know, the fragment's public constructor must be empty.

You cannot do it from Fragment's constructor. Move your code to onActivityCreated() method.

Creating a new Intent in the constructor is a really bad idea. An example from the android's developer guide
Code:
public class MainActivity extends AppCompatActivity {
public static final String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/** Called when the user taps the Send button */
public void sendMessage(View view) {
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.editText);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
