Oh, i fixed it :D ClickService was not registered in AndroidManifest

How do i modify data on my MainActivity from Settings Activity?

I've tried many other threads and articles but I just can't find the right stuff that I am looking for.
So I have a MainActivity and a SettingsActivity both are java classes. In my main activity there is a button when pressed, increases the count by +1, and shows it on a TextView, it also makes the device vibrate on every increment/Every button press. I want to make a switchpreference in SettingsActivity which if kept off/false, turns off the vibration on button press and if kept on/true, turns on the vibration on button press.
I don't know how to retrieve the state of SwitchPreferenceCompat(ON OR OFF) from SettingsActivity and use it in the MainActivity, so if the user turns the switch off in setting activity, the vibration should stop on button press which is in MainActivity.
I have already used Shared Preferences in MainActivity for saving the current count/number when App is closed and resumes from the same count when reopened.

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.settings_activity);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.settings, new SettingsFragment())
.commit();
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
public static class SettingsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.root_preferences, rootKey);
}
}
}
root_preference.xml
<PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory app:title="Settings"
app:iconSpaceReserved="false">
<SwitchPreferenceCompat
app:key="Switchsett1"
app:title="Vibration"
app:summaryOff="Turn Vibration On"
app:summaryOn="Turn Vibration Off"
app:iconSpaceReserved="false"
app:defaultValue="true"
/>
<SwitchPreferenceCompat
app:key="Switchset2"
app:iconSpaceReserved="false"
app:summaryOff="#string/attachment_summary_off"
app:summaryOn="#string/attachment_summary_on"
app:title="#string/attachment_title" />
</PreferenceCategory>
</PreferenceScreen>
I don't know how to retrieve the state of switch(ON OR OFF) from SettingsActivity
To get the value of SwitchPreferenceCompat from shared preference, then you need to retrieve it as a Boolean
Now the key of your first SwitchPreferenceCompat is Switchsett1, so to retrieve the value of this:
public class MainActivity extends AppCompatActivity {
Boolean switchPref;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
....
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
switchPref = prefs.getBoolean("Switchsett1", false);
Toast.makeText(this, String.valueOf(switchPref), Toast.LENGTH_SHORT).show(); // shows true if the SwitchPreferenceCompat is ON, and false if OFF.
Now the Toast in the above script shows true if the SwitchPreferenceCompat is ON, and false if it's OFF.
You can do the same for Switchset2 SwitchPreferenceCompat

Losing state of the activity when navigating from notification to activity

I have an activity named Player Activity in which I am streaming music with the help of MediaPlayer API. Whenever my activity is created a notification is displayed which has some basic control of the music player.
So when I tap on my notification it jumps back to the Player Activity, but the state of the activity is lost.
Before tapping on notification :
After tapping on notification :
Here is the code of my notification's Pending Intent
Intent notifyIntent = new Intent(context, PlayerActivity.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
notifyIntent.setAction("android.intent.action.MAIN");
notifyIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Thanks in advance. Pardon me if the explanation is not clear, because if i might have right words to explain it, I would have googled it.
Add this to your PlayerActivity activity in manifest :
android:launchMode="singleTask"
And use these flags in the intent for pendingintent :
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

Implementing audio app notification in Android

The purpose of application is to play some radio stations via url streaming using exoplayer. The problem encountered is that when the app is running and the notification starts there are 2 different streams playing one by my button press from the radio UI and one by the notification.
My question is how can I make it so when I press a button on the UI it changes the the stream on the notification player as well.
P.S. I have tried importing one player however that proved from mainactivity.java by calling it a static however that causes a memory leak and the stream stop in the foreground service.
I used the notificationPlayerManager(exoplayer) from here: https://www.youtube.com/watch?v=svdq1BWl4r8

After some research I have found an answer. For anyone else looking bind the main activity to the service.
In that process I have used this method to bind the player from the service:
public SimpleExoPlayer getPlayer1()
{
return player1;
}
Then call it in your main:
player = myServices.player1;

Android cannot be referenced from a static context

I'm a beginner on Android and this is the first I'm creating an app named GeoQuiz which basically has a few questions and the user has to click true/false or request the answer with the cheat button.I'm getting this one line of error related with a non-static an a static context in line 138,what am I doing wrong? I'm trying that every time i click on the button cheat, it open the other window that is under a different .xml file and in an another java class

this is the class for the cheat class and cheatButton
package com.example.fusion.geoquiz;
import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.Button;
import android.widget.ImageButton;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
import android.widget.TextView;
import android.util.Log;
/**
* Created by fusion on 1/21/2015.
*/
public class cheatActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cheat);
}
}
Replace
Intent intent = new Intent(QuizActivity.this, cheatActivity.startActivity(intent));
with
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
See the docs for more details..
Not sure what you're doing there, but you need to reference the other activity class. Simply calling startActivity is enough, because it will be implicitly called from QuizActivity.this.
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
To save you from future errors choose one activity class that you will be using either Activity or ActionBarActivity. The latter is from the support package.
