How to save state of a progressbar when app is killed?

I am building a simple downloader app, with a pause/resume button. When I click on pause button and kill the app the download progress isn't shown anymore, after I open the app again. I want to save the download progress state even if the app is killed. Can anyone help me with this? I'm building the app using download manager pro library from github.
here's the code:

I don't know how you want to save the state but I do know that an activity has a onStop() method that you can override.
The onStop() method runs when the app is killed so I would imagine you would want to do your "saving" in this method.
As for saving something I believe you would want to use the SharedPreferences class. You can find more information about that here.
You can find the lifecycle of an activity here
hope this helps

Save the progress on SharedPreferences onDestroy() and retrieve it from there when activity is created.
Cache:
#Override
protected void onDestroy() {
super.onDestroy();
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("progress", progress).apply();
}
And retrieve:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences sharedPreferences = getSharedPreferences("space_name", MODE_PRIVATE);
progress = sharedPreferences.getInt("progress", 0); // 0 default value in case is empty
}

Open an app using voice recognition (PocketSphinx)

I want to create a voice recognition app in android and run it in service so i can use it even without in the app. So i looked for reference and i found in GitHub a demo app.
This is the site https://github.com/ihrupin/SpeechRecognitionService
I download the app and also i read the documentation, Yes it running well to me it also running in service, but i really want is for example if i said (open Facebook) it will open the installed Facebook app.
I'm newbie in using the PocketSphinx.
This is the MainActivity

}
}
}
I've researched about this topic and i found out that i must modify the grammar and the dictionary but i don't know how to do that. Any ideas?

If you want to modify the existing grammer and want to add your own words you have to modify it a little bit.
write this line in your recognizer setup method.
recognizer.addKeyphraseSearch("facebookPhrase", "Open Facebook");
To edit this example you can read about on official website here

How to check if no beacons are available Android

I am trying to play around with Beacons and I have got this code:
By following this tutorial:
Activity2.java
public class Activity2 extends AppCompatActivity {
//String myString = MyViewClass.infoToPass;
public static final String TAG = "Airport";
TextView tvFooter;
private static final Map<String, List<String>> PLACES_BY_BEACONS;
// TODO: replace "<major>:<minor>" strings to match your own beacons.
static {
Map<String, List<String>> placesByBeacons = new HashMap<>();
placesByBeacons.put("22504:48827", new ArrayList<String>() {{
add("Heavenly Sandwiches");
// read as: "Heavenly Sandwiches" is closest
// to the beacon with major 22504 and minor 48827
add("Green & Green Salads");
// "Green & Green Salads" is the next closest
add("Mini Panini");
// "Mini Panini" is the furthest away
}});
placesByBeacons.put("648:12", new ArrayList<String>() {{
add("Mini Panini");
add("Green & Green Salads");
add("Heavenly Sandwiches");
}});
PLACES_BY_BEACONS = Collections.unmodifiableMap(placesByBeacons);
}
private List<String> placesNearBeacon(Beacon beacon) {
String beaconKey = String.format("%d:%d", beacon.getMajor(), beacon.getMinor());
if (PLACES_BY_BEACONS.containsKey(beaconKey)) {
return PLACES_BY_BEACONS.get(beaconKey);
}
return Collections.emptyList();
}
private BeaconManager beaconManager;
private Region region;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_2);
//updateCordinate("Just some random text");
Log.d(TAG, "onCreate");
beaconManager = new BeaconManager(this);
beaconManager.setRangingListener(new BeaconManager.RangingListener() {
#Override
public void onBeaconsDiscovered(Region region, List<Beacon> list) {
Log.d(TAG, "onBeaconsDiscovered");
if (!list.isEmpty()) {
Beacon nearestBeacon = list.get(0);
List<String> places = placesNearBeacon(nearestBeacon);
// TODO: update the UI here
Log.d(TAG, "Nearest places: " + places);
}
else{
// this line is not executing
Log.d(TAG, "You are not in area of beacons");
}
}
});
region = new Region("ranged region", UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"), null, null);
}
#Override
protected void onResume() {
super.onResume();
Log.d(TAG, "onResume");
SystemRequirementsChecker.checkWithDefaultDialogs(this);
beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
#Override
public void onServiceReady() {
Log.d(TAG, "onServiceReady");
beaconManager.startRanging(region);
}
});
}
#Override

beaconManager.stopRanging(region);
Log.d(TAG, "onPause");
super.onPause();
}
//public void updateCordinate(String text1) {
// tvFooter = (TextView) findViewById(R.id.tvFooter);
// tvFooter.setText("Location is :" + myString);
// }
}
Now what I want it:
If I don't have any Beacons around me, I want to check for it and store that value in some variable so that I can use it in other class (non-activity class).
Also how do I check for range from it? (I know it's beyond the scope of this question but little idea will be welcomed)

//you may ignore the notification code, for my usage of Beacons in my app, i
//to send notification to my app even through the app is not open when a beacon //is in/out range.

My Android ActivityRecognition implementation is too slow

But It seems too slow. What's the problem?
It doesn't related to internet connectivity.

mGoogleApiClient.connect();
}

Intent intent = new Intent(this, ActivityRecognitionService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mGoogleApiClient, 1000, pendingIntent);
}
#Override
public void onConnectionSuspended(int i) {
Toast.makeText(Walking.this, "Hello1", Toast.LENGTH_SHORT).show();
Log.e("Connection Failed : ", "Connection Failed");
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(Walking.this, "Hello2", Toast.LENGTH_SHORT).show();

I don't think there is any problem with your code, it looks exactly the same as mine.
The normal rate for detection is 3 seconds -> 6 seconds if your "detectionIntervalMillis" value = 0.
But when you switch between 2 different activities (for example: from walking -> in the car....) it will take more, maybe 20s to 40s.

GoogleFit wasn't able to connect, so the request failed-Android

I have the following code where it does two main things.
It connects to google play services.
Inside the onConnected() method a service is started, by calling the startService(...) method.
When I run the program I get the following log message.
Connected!!!
Fit wasn't able to connect, so the request failed.
GoogleFitService destroyed.
Here is my code:
public class MainActivity extends ActionBarActivity {
public final static String TAG = "GoogleFitService";
private static final int REQUEST_OAUTH = 1;
private static final String AUTH_PENDING = "auth_state_pending";
private boolean authInProgress = false;
private GoogleApiClient mClient = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buildFitnessClient();
}
private void buildFitnessClient() {
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.API)
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
#Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
// Put application specific code here.
Intent service = new Intent(MainActivity.this,
GoogleFitService.class);
service.putExtra(GoogleFitService.SERVICE_REQUEST_TYPE,
GoogleFitService.TYPE_REQUEST_CONNECTION);
startService(service);
}
#Override
public void onConnectionSuspended(int i) {
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG, "Connection lost. Reason: Service Disconnected");
}
}
}
)
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
// Called whenever the API client fails to connect.
#Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Connection failed. Cause: " + result.toString());
if (!result.hasResolution()) {
// Show the localized error dialog
GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), MainActivity.this, 0).show();
return;
}
if (!authInProgress) {
try {
Log.i(TAG, "Attempting to resolve failed connection");
authInProgress = true;
result.startResolutionForResult(MainActivity.this, REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception while starting resolution activity", e);
}
}
}
}
)
.build();
}
#Override
protected void onStart() {
super.onStart();
// Connect to the Fitness API
Log.i(TAG, "Connecting...");
mClient.connect();
Intent service = new Intent(this, GoogleFitService.class);
service.putExtra(GoogleFitService.SERVICE_REQUEST_TYPE, GoogleFitService.TYPE_REQUEST_CONNECTION);
startService(service);
}
#Override
protected void onStop() {
super.onStop();
if (mClient.isConnected()) {
mClient.disconnect();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_OAUTH) {
authInProgress = false;
if (resultCode == RESULT_OK) {
// Make sure the app is not already connected or attempting to connect
if (!mClient.isConnecting() && !mClient.isConnected()) {
mClient.connect();
}
}
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean(AUTH_PENDING, authInProgress);
}
}
And the second class is basically an Intent service. Maybe the mistake is here.

Any ideas what might went wrong? Thanks, Theo.

You need to access those detail from fit only when it connected .And Try this
public void buildFitnessClient() {
fitnessClient = new GoogleApiClient.Builder(context)
.addApi(Fitness.HISTORY_API)
.addApi(Fitness.SESSIONS_API)
.addApi(Fitness.RECORDING_API)
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_NUTRITION_READ_WRITE))
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
#Override
public void onConnected(Bundle bundle) {
ReferenceWrapper.getInstance(context).setApiClient(fitnessClient);
((OnClientConnectListener) context).onclientConnected();
}
#Override
public void onConnectionSuspended(int i) {
}
})
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
#Override
public void onConnectionFailed(
ConnectionResult result) {
if (!result.hasResolution()) {
GooglePlayServicesUtil.getErrorDialog(
result.getErrorCode(), context, 0)
.show();
return;
}
if (!authInProgress) {
try {
authInProgress = true;
result.startResolutionForResult(
context,
KeyConstant.REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
}
}
}
}).build();
}
And at first you need to register your application on google api console . Generate an outh2 client id from there and enable fitness api . Search for fitness Api in api Dashboard , and enable it.. And override OnActivityresult
in your Activity .
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == KeyConstant.REQUEST_OAUTH) {
fitnessHelper.setAuthInProgress(false);
if (resultCode == Activity.RESULT_OK) {
if (!fitnessHelper.isConnecting() && !fitnessHelper.isConnected()) {
fitnessHelper.connect();
}
}
}
}
