I'm trying to store my device token from my android app programmatically to AWS SNS platform application.
I'm getting an error in getApplicationContext() method. Anyone with a solution for this error?
This is my code:
public class RegisterIdForAWS extends AsyncTask<String, Void, Void> {
private Exception exception;
#Override
protected Void doInBackground(String... strings) {
try {
String pushNotificationRegId = FirebaseInstanceId.getInstance().getToken();
if (pushNotificationRegId != null) {
CognitoCachingCredentialsProvider provider = new CognitoCachingCredentialsProvider(
getApplicationContext(),
"us-west-2:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
Regions.US_WEST_2);
String platformApplicationArn = "arn:aws:sns:us-west-2:11111111111:app/GCM/123";
AmazonSNSClient pushClient = new AmazonSNSClient(provider);
pushClient.setRegion(Region.getRegion(Regions.US_WEST_2));
String customPushData = "";
CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();
platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);
CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(platformEndpointRequest);
Log.w(TAG, "Amazon Push reg result: " + result);
}
} catch (Exception e) {
this.exception = e;
}
return null;
}
protected void onPostExecute(String text) {
Log.w(TAG, "Amazon Push reg Finished");
}
}
In constructor of your async class, pass Context
private Context mContext;
public RegisterIdForAWS (Context context){
mContext = context;
}
And instantiate class like this:
RegisterIdForAWS task = new RegisterIdForAWS (context);
Hope it helps.

Can someone help me understand what the issue is?

I am working with Google App Engine .I want to Send GCM toke(RegID) to App Engine Server.But Problem is that when i pass RegId as a parameter Nothing happen and when i pass normal string like"abcefghi" the string is passed to server
my code is shown below
public class SendInstanceidAsync extends AsyncTask<Void, Void, UpdateInstanceIdResult> {
private UpdateinstanceidAPI updateinstanceidAPIservice;
private String token;
private String scholarNumber;
private String schoolId;
private RegistrationIntentService registrationIntentService;
public SendInstanceidAsync(RegistrationIntentService registrationIntentService, String token, String schoolId, String scholarNumber) {
this.token = token;
this.scholarNumber = scholarNumber;
this.schoolId = schoolId;
this.registrationIntentService = registrationIntentService;
}
#Override
protected UpdateInstanceIdResult doInBackground(Void... params) {
UpdateInstanceIdResult updateInstanceIdResult = new UpdateInstanceIdResult();

return updateInstanceIdResult;

I have an Activity which constructs a RESTManager class (used to make an asynchronous call to the server and return data to the Activity).
However, after I construct my RESTManager and call the server using
//Retrieve data from server
RESTManager m = new RESTManager(this,getApplicationContext());
//Set the data list
m.delegate=this;
m.retrieveRoomData();
the server call does not go through until I turn off bluetooth scanning.
However, I start my bluetooth scan immediately after the RESTManager as such:
beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.setBackgroundScanPeriod(1100l);
beaconManager.setBackgroundBetweenScanPeriod(100l);
beaconManager.setForegroundScanPeriod(1100l);
beaconManager.setForegroundBetweenScanPeriod(100l);
//Set the custom BeaconLayout for iBeacons
if (myPref.getBoolean("layoutSet", true)) {
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:0-3=4c000215,i:4-19,i:20-21,i:22-23,p:24-24"));
backgroundPowerSaver = new BackgroundPowerSaver(this);
Log.v("Beacon Layout", "Beacon Layout Set");
myPref.edit().putBoolean("layoutSet", false).apply();
myPref.edit().commit();
}
beaconManager.bind(this);
I am not getting any error.
Is there any reason why my AsyncTask from RESTManager would hang from the bluetooth scans?

public class HomeFragment extends Fragment {

#Override

super.onViewCreated(view, savedInstanceState);
statLoc = new ShareLink();
statLoc.execute();
}
The above code is my fragment and am executing a class named ShareLink().
In that ShareLink class I used implicit intent to send data like below
public class ShareLink extends AsyncTask<String, String, String> {
String urlShare = DeviceIdGen.hmUrl;
String statusLoc = null;
public static String locLink = null;
private static String loc = null;
Context context;
String locUrl;
protected String doInBackground(String... params) {
WebServiceTasks wstShare = new WebServiceTasks();
return wstShare.getMethod(urlShare);
}
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jResult = new JSONObject(result);
statusLoc = jResult.getString("status");
if (statusLoc.equals("success")) {
loc = jResult.getString("link");
locUrl = "My Current Location :" + locLink + "\n\n"
+ "My Key : " + loc;
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
startActivity((emailIntent).putExtra(
android.content.Intent.EXTRA_TEXT, locUrl));
}
} catch (JSONException e) {
e.printStackTrace();
}}}
But am not able to achieve it. Please help as am a newbie
Just Edit your AsyncTask,
Add a constructor to it
public class ShareLink extends AsyncTask<String, String, String> {
String urlShare = DeviceIdGen.hmUrl;
String statusLoc = null;
public static String locLink = null;
private static String loc = null;
String locUrl;
private Context context = null;
public ShareLink(Context context) {
this.context = context;
}
protected String doInBackground(String... params) {
WebServiceTasks wstShare = new WebServiceTasks();
return wstShare.getMethod(urlShare);
}
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jResult = new JSONObject(result);
statusLoc = jResult.getString("status");
if (statusLoc.equals("success")) {
loc = jResult.getString("link");
locUrl = "My Current Location :" + locLink + "\n\n"
+ "My Key : " + loc;
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
context.startActivity((emailIntent).putExtra(
android.content.Intent.EXTRA_TEXT, locUrl));
}
} catch (JSONException e) {
e.printStackTrace();
}}}
And invoke your AsyncTask as
statLoc = new ShareLink(getActivity());
statLoc.execute();
you could pass a context or an activity to your ShareLink class and use that instance to start your intent.
for example
private Context context;
public ShareLink (Context context){
this.context = context;
}
and then in your onPostExecute you can use context.startActivity() or whatever you wanna do with the intent.
Is there a way to get the token that was used to log in the user with Google Play Game Services?
I'm looking for something like:
#Override
public void onSignInSucceeded() {
String email = getGamesClient().getCurrentAccountName();
String token = getGamesClient().getToken();
}
I need this to authenticate the user when they are contacting my own server.
This is how I managed to get the token:
#Override
public void onSignInSucceeded() {
String email = getGamesClient().getCurrentAccountName();
String scopes = getScopes();
new registerBackground(getApplicationContext()).execute(email, scopes);
}
private class registerBackground extends AsyncTask<String, Void, Void> {
Context context;
registerBackground (Context context) {
this.context = context;
}
#Override
protected Void doInBackground(String... params) {
try {
String oAuthToken = GoogleAuthUtil.getToken(context, params[0], params[1]);
...
catch (Exception e) {
e.printStackTrace();
}
}
...
}
