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

public class cheatActivity extends Activity{

}
}
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.

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.

</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
I have problem with Runnable. It don't want to works, and i don't know what is the problem, because it is works in my other app... Can somebody help me?
Just example, there are "healt" with deafult value=5, for the test i made a button, when i click button, healt value -1... and i want start Runnable when health<5... and add +1 to health.... for the test i setted the Runnable 1 secunds

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

So i developed an android news app. A spinner item is available on the toolbar and data reloads according to spinner selection. However, when the data reloads, for some of the items, it directly loads the relevant content but for some others, it loads the previously selected spinner data. Current data for the current item only shows after reloading same spinner data using the swipe refresh functionality which i had implemented. I want the correct data relevant to that selection to load the first time itself without having to refresh all the time.
Below is my MainActivity where all these functions are called.

I discovered that from API level 3, one can use the onUserInteraction() on an Activity with a boolean value thereby determining the user's interaction.
Find the documentation in the link below.
http://developer.android.com/reference/android/app/Activity.html#onUserInteraction()
#Override
public void onUserInteraction() {
super.onUserInteraction();
userInteracts = true;
}
The my adjustment goes as thus in the MainActivity.java
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
int check = 0;
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (IsInteracting) {
Intent intent = getIntent(); //MainActivity
String itemSelected = mySpinner.getItemAtPosition(mySpinner.getSelectedItemPosition()).toString();
//TODO: DONE
prefManager.spinWriteString(itemSelected);
Toast.makeText(getApplicationContext(), "Constituency News Now Showing", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}

I have a problem with admob ads.
The banner ad seems to work fine but the Interstitial is not loading.
I have tried various solutions, generating different ad unit id's and trying admob test ids.

The simplest answer is that mode is not equal to "qteday"
if(mode.equals("qteday")){
Unless that is true, the interstitial will never be loaded.
I have made a quiz application which include 5 questions. I have made a ResultActivity page which displays result of the quiz.
I have added a countDown timer of 20 sec for each question. When the Countdown timer finishes it moves to the next question automatically. When the questions are finished it should move to the ResultActivity page to display result.
I have only one issue...
Afetr reaching my last Question..if i does not select any answer and timer is finished the applicaton is not moving to my ResultActivity page..The timer is getting started again and again on the same question until i select any option

This is because Your return false statement will never be reached if the user has made no choice:
if (rda.isChecked() || rdb.isChecked() || rdc.isChecked()){}
in this if else statement You will return false later. But if none is selected, You automatically will return true because the code block inside this statement above will not be rached. And then in Your timer You say:
if (getNextQuestion(false)) {
// Start The timer again
countDownTimer.start();
}
getNextQuestion is allways true if the user makes no choice, so the timer starts again and again.
