When using Floating Bubble as a Background Service to take a screenshot of Live Screen. Getting two Errors

enter code here BackgroundService-
private void addNewBubble ()//ERROR , Expression expected and Missing ';' token{
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
//here is all the science of params
final WindowManager.LayoutParams myParams = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
PixelFormat.TRANSLUCENT
);
BubbleLayout bubbleView = (BubbleLayout) LayoutInflater.from(BackgroundService.this).inflate(R.layout.bubble_layout, null);
bubbleView.setLayoutParams(myParams);
bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
#Override
public void onBubbleRemoved(BubbleLayout bubble) {
}
});
bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {
#Override
public void onBubbleClick(BubbleLayout bubble) {
Bitmap b = Screenshot.takescreenshotOfRootView(imageView);
imageView.setImageBitmap(b);
main.setBackgroundColor(Color.parseColor("#999999"));
//Toast.makeText(getApplicationContext(), "Clicked !",
// Toast.LENGTH_SHORT).show();
}
});
bubbleView.setShouldStickToWall(true);
bubblesManager.addBubble(bubbleView, 60, 20);
}
}
private void initializeBubblesManager() {
bubblesManager = new BubblesManager.Builder(this)
.setTrashLayout(R.layout.bubble_trash_layout)
.setInitializationCallback(new OnInitializedCallback() {
#Override
public void onInitialized() {
addNewBubble();// ERROR
}
})
.build();
bubblesManager.initialize();
}
}
This is the OnStart method which includes all the methods to create the floating bubble and to make it clickable to take a screenshot. Only addNewBubble is showing errors , whereas when the Floating Bubble code is run on the MainActivity without the creation of BackgroundService it runs fine without any errors.
Any suggestions as to what to do ?

Copy paste this code .I have tested it

like this.

How to recreate the spotify demo on android studio 2?

I've tried following the instructions on the spotify android sdk site and when I tested it on my emulator, all I got was a white screen. I understand the demo code is supposed to pull up a login request and then play a song track if the login was successful am I right?

Android Studio cannot resolve com.google.android.gms.nearby.messages.SubscribeOptions.Builder

Can anyone tell me what I'm doing wrong?

My guess is that you will be able to resolve this by updating the Play Services version you are using from v7.8.0 to v8.4.0 (the latest version as of this answer date). The Nearby APIs were introduced in v7.8.0, at which time subscription could be accomplished using a method signature of the form
subscribe(GoogleApiClient, MessageListener, Strategy)
However, this method is now (in v8.4.0) marked as deprecated, and a new method with the following signature is recommended in its place:
subscribe (GoogleApiClient, MessageListener, SubscribeOptions)
Based on this information it seems fairly likely that the SubscribeOptions type was introduced whenever the previously-described deprecation took place, which was clearly post-v7.8.0.
See these docs for reference.

Please check this link of your answer & let me know if you find any problem in fb integration.
Unable to get emailId after login through fb in android

call this in your main Activity or the activity that is using FaceBookSignIn method
FacebookSdk.sdkInitialize(MainActivity.this);
add this method in your activity
public void FaceBookSignIn() {
callbackManager = CallbackManager.Factory.create();
loginType = Constants.loginTypeFaceBook;
LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("email", "user_photos", "public_profile"));
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Success", true);
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {
try {
String email = jsonObject.getString(Constants.FacebookEmail),
String name = jsonObject.getString(Constants.FacebookName),
String firstName = jsonObject.getString(Constants.FacebookFirstName),
String lastName = jsonObject.getString(Constants.FacebookLastName),
String id = jsonObject.getString(Constants.FacebookID);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,first_name,last_name,birthday,email");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Sign In Cancel", true);
}
#Override
public void onError(FacebookException e) {
DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Error", true);
}
});
}
Don't forget to add this dependency in your gradle build file
compile 'com.facebook.android:facebook-android-sdk:4.5.0'

Finding current location in android using google play services

I found a tutorial on the android developer site for finding the location using google play services.
The link:http://developer.android.com/training/location/retrieve-current.html
It works perfectly fine.But there is a certain part of the code which is required for checking whether google play services is available on the device.But i dont know how to use it in my code.For example there is a method as follows:
private boolean servicesConnected() {
// Check that Google Play services is available
int resultCode =
GooglePlayServicesUtil.
isGooglePlayServicesAvailable(this);
// If Google Play services is available
if (ConnectionResult.SUCCESS == resultCode) {
// In debug mode, log the status
Log.d("Location Updates",
"Google Play services is available.");
// Continue
return true;
// Google Play services was not available for some reason.
// resultCode holds the error code.
} else {
// Get the error dialog from Google Play services
Dialog errorDialog = GooglePlayServicesUtil.getErrorDialog(
resultCode,
this,
CONNECTION_FAILURE_RESOLUTION_REQUEST);
// If Google Play services can provide an error dialog
if (errorDialog != null) {
// Create a new DialogFragment for the error dialog
ErrorDialogFragment errorFragment =
new ErrorDialogFragment();
// Set the dialog in the DialogFragment
errorFragment.setDialog(errorDialog);
// Show the error dialog in the DialogFragment
errorFragment.show(getSupportFragmentManager(),
"Location Updates");
}
return false;
}
}
Also there are other methods which i dont understand.Like the following:
public static class ErrorDialogFragment extends DialogFragment {
// Global field to contain the error dialog
private Dialog mDialog;
// Default constructor. Sets the dialog field to null
public ErrorDialogFragment() {
super();
mDialog = null;
}
// Set the dialog to display
public void setDialog(Dialog dialog) {
mDialog = dialog;
}
// Return a Dialog to the DialogFragment.
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return mDialog;
}
}
/*
* Handle results returned to the FragmentActivity
* by Google Play services
*/
#Override
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
// Decide what to do based on the original request code
switch (requestCode) {
case CONNECTION_FAILURE_RESOLUTION_REQUEST :
/*
* If the result code is Activity.RESULT_OK, try
* to connect again
*/
switch (resultCode) {
case Activity.RESULT_OK :
/*
* Try the request again
*/
break;
}
}
}
The first error dialog class if for displaying error.The onactivityresult is probably used when
connectionResult.startResolutionForResult(this,ONNECTION_FAILURE_RESOLUTION_REQUEST);
is called.
My question is where servicesConnected() should be called?

First of all from your onCreate() method just call this method. After calling this method, and where exactly you get callback of this method, check it, is it available or not. If its available then proceed to fetch location data else show error dialog that Google Play Services is not available in your device, please enable from settings.
