Google Achievements Unlock But Don't Save

I added achievements to my Google Play game following Google's tutorial. They unlock fine and if I display achievements in-game immediately they show up. If I quit the game and go to the Google Game's app they don't show up and they disappear from in-game also. Any ideas? I've tried multiple accounts. Thanks!

EMDK Serial Communication Finds No Ports

I am trying to create an Android activity which sends data through the serial port as a product test. I have some code for doing so, which, so far, finds no serial ports on my device which definitely has a serial port. I intend to use this activity with a loopback connector on the serial port of the device to verify both the read and write functionalities. I have tried these two programs:

Does the problem seem to be with my code or is there something I am not understanding about the device itself? Any help would be appreciated. Thank you for your time.

Splash Screen Delay timer wait till permission dialog close in android

I am collecting GPS location data in Splash Screen and store it in session, and use it later in MainActivity. If the GPS is turn off or used for the first time it will ask for permission in my splash screen. The problem is that I am using the timer to move splash screen Activity to another activity. Due to the timer, SplashScreen is moving to next the activity without the permission. I want my Splash screen to wait till permission dialog is allowed or denied. Below is my code

If you do not understand please comment.

Try this solution.
First of all, make your onCreate() method this way:
#Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
session = new Session(SplashActivity.this);
//GPS Tracker
permissions.add(ACCESS_FINE_LOCATION);
permissions.add(ACCESS_COARSE_LOCATION);
permissionsToRequest = findUnAskedPermissions(permissions);
//get the permissions we have asked for before but are not granted..
//we will store this in a global list to access later.
welcomeText = (TextView) findViewById(R.id.welcome);
tf1 = Typeface.createFromAsset(getAssets(), "fonts/Roboto-Light.ttf");
welcomeText.setTypeface(tf1);
mLogo = (ImageView) findViewById(R.id.applogo);
zbgimg = (ImageView) findViewById(R.id.zbgimg);
zbgimg.setImageResource(R.drawable.splash_screen_option_three);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (permissionsToRequest.size() > 0)
requestPermissions(permissionsToRequest.toArray(new String[permissionsToRequest.size()]), ALL_PERMISSIONS_RESULT);
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
}
Then make separate setUserLocation() function outside of onCreate() as follow:-
public void setUserLocation() {
locationTrack = new LocationTrack(SplashActivity.this);
if (locationTrack.canGetLocation()) {
double longitude = locationTrack.getLongitude();
double latitude = locationTrack.getLatitude();
Geocoder gcd = new Geocoder(SplashActivity.this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = gcd.getFromLocation(latitude, longitude, 1);
} catch (IOException e) {
e.printStackTrace();
}
if (addresses != null && addresses.size() > 0) {
String locality = addresses.get(0).getLocality();
String subLocality = addresses.get(0).getSubLocality();
String address = addresses.get(0).getAddressLine(0);
String state = addresses.get(0).getAdminArea();
String countryn = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName();
session.setLocation(latitude,longitude,locality,subLocality);
//Toast.makeText(SplashActivity.this,locality +" "+ postalCode + " " + latitude+ " " + longitude,Toast.LENGTH_SHORT).show();
}
startApp();
} else {
locationTrack.showSettingsAlert();
}
}
One more separate function startApp() outside onCreate() like below:-
public void startApp() {
new Handler().postDelayed(new Runnable() {
#SuppressLint("PrivateResource")
#Override
public void run() {
if (session.FbLoggedIn()) {
Intent i = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(i);
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
} else {
Intent i = new Intent(SplashActivity.this,
LoginActivity.class);
startActivity(i);
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
}
}
}, 3000);
}
And last thing, change onRequestPermissionsResult() method like below:-
#TargetApi(Build.VERSION_CODES.M)
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case ALL_PERMISSIONS_RESULT:
for (String perms : permissionsToRequest) {
if (!hasPermission(perms)) {
permissionsRejected.add(perms);
}
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (permissionsRejected.size() > 0) {
if (shouldShowRequestPermissionRationale(permissionsRejected.get(0))) {
showMessageOKCancel("These permissions are mandatory for the application. Please allow access.",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissionsRejected.toArray(new String[permissionsRejected.size()]), ALL_PERMISSIONS_RESULT);
}
}
});
return;
}
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
break;
}
}
So, this solution follow permission first, then user-Location and then startApp.

If I understand correctly you want to access location before going jumping from splash screen. If so just remove timer open and as splash screen opens make it check for location service on/off and get location and then jump to another activity.
if (!canGetLocation()) {
showSettingsAlert();
} else {
fetch location
if (session.FbLoggedIn()) {
startActivity(new Intent(SplashActivity.this, MainActivity.class));
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
} else {
startActivity(new Intent(SplashActivity.this, LoginActivity.class));
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
}
}

Bluetooth LE write to device

I am using some of the samples provided on line which show how to write to a device. What i want to do is as it loads up the device services and characteristics the app writes data to the tag, rather than open up a dialog to do this.
Can anyone shed some light on this please as i am new to Android development.
I have tried to add edit the code within the following section...
private void displayGattServices(List<BluetoothGattService> gattServices) {
but this line causes the app to crash...
byte[] bytes = DeviceControlActivity.this.mWriteCharacteristic.getValue();
As i tried to move the write part of the code from
public class BleCharacterDialogFragment extends DialogFragment
as i thought that would write to the BLE device.
All help is much appreciated, thanks. Below is the code i have. It came from https://github.com/suzp1984/Light_BLE originally.

To write a value to a device you have to know tow things
1-Service UUID
2-Characteristic UUID
You can read/write a value from/to Characteristic UUID
Here is the sample code to write a value to Characteristic.
public void writeCharacteristic(byte[] value)
{
BluetoothGattService service = mBluetoothGatt.getService(YOUR_SEVICE_UUID);
if (service == null) {
System.out.println("service null"); return;
}
BluetoothGattCharacteristic characteristic = service.getCharacteristic(YOUR_CHARACTERISTIC_UUID);
if (characteristic == null) {
System.out.println("characteristic null"); return;
}
characteristic.setValue(value);
boolean status = mBluetoothGatt.writeCharacteristic(characteristic);
System.out.println("Write Status: " + status);
}
