Calling a method in the background to retrieve data every couple of minutes

I am developing an android app to retrieve data through php,mysql,json from a database. I need to create a service or any way to call getData() method every 10 minutes. I tried placing these 2 methods in a broadcast receiver and used alarm manager to repeat every 10 mins but it didn't run properly, it worked only for Toast and Log.d (simple operations). Is there an simple approach to achieve what I want ? I did search a lot, but couldn't find a clear answer
//METHOD 1
private void getData() {
loading = ProgressDialog.show(this,"Please wait...","Fetching...",false,false);
String url = Config.DATA_URL;
StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
loading.dismiss();
showJSON(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this,error.getMessage().toString(),Toast.LENGTH_LONG).show();
}
});
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
// METHOD 2
private void showJSON(String response){
String id="";
String time="";
String value = "";
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray result = jsonObject.getJSONArray(Config.JSON_ARRAY);
for (int i = 0; i < result.length(); i++) {
JSONObject tempData = result.getJSONObject(i);
id = tempData.getString(Config.KEY_NAME);
time = tempData.getString(Config.KEY_ADDRESS);
value = tempData.getString(Config.KEY_VC);
String data = "Id:\t"+id+", Time:\t" +time+ ", Value:\t"+ value;
all += data+"\n";
}
}
catch (JSONException e) {
e.printStackTrace();
}
textViewResult.setText(all);
}

Your way of using a broadcast receiver (BR) and an Alarm manager sounds like a good approach and I'm not sure exactly what problem you encountered. Could you tell us more?
Without all the details I'd say that a potential problem is that a Broadcast receiver is normally executed in the UI thread of Android and that does not for example allow you to perform network access and it must finish within X seconds.
1) You don't have the right permissions to access internet? From what I remember the log of this can be easy to miss.
2) Either you can request the BR to run the a background thread, I know you can do it, not tried myself.
3) You can start another thread. As you seen to update the UI you should probably use an Async Task for this. So you can do the network in a background thread and then you you get a call in the UI thread with the new data. (This would probably be the option to go to)
Side note: for parsing json, I'd recommend you to look at Gson. It's a library from google that makes the parsin of Json much simpler. https://github.com/google/gson

Control DOM elements from android app

I'm trying to take control over the Play/Pause html DOM elements (in a browser open in a pc) from an android device.
In the html page (in Google Chrome browser) there's a <video> tag so I can control it like this:
//js code
document.querySelector("video").play();
document.querySelector("video").pause();
But I want that to run from an android device so I'm using GCM.
I read here and got some insight but I still have some questions.
First, since I'm writing in eclipse, and it sees no document variable, it produces an error. So how can eclipse recognize that element in the html page so I can compile and install the apk on the device?
Where do I specify the page url I want to communicate with? (send play/pause commands)
To run js inside java I'm using Rhino. I looked through the examples in the documentation but I'm still not sure if a #JSFunction annotation is enough to declare a js function.
Here's my code:
import com.alaa.chromote.util.SystemUiHider;
import com.google.android.gcm.GCMRegistrar;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.Toast;
import android.view.View.OnClickListener;
import org.mozilla.javascript.*;
import org.mozilla.javascript.annotations.*;
public class MainApplication extends Activity {
private final static String GCM_SENDER_ID = "484514826047";
private static final String LOG_TAG = "GetAClue::GCMIntentService";
private Button playButton;
private Button pauseButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_application);
playButton = (Button) findViewById(R.id.PlayButton);
pauseButton = (Button) findViewById(R.id.PauseButton);
playButton.setVisibility(View.INVISIBLE);
pauseButton.setVisibility(View.VISIBLE);
//connect to gcm
GCMRegistrar.checkDevice( this );
GCMRegistrar.checkManifest( this );
final String regId = GCMRegistrar.getRegistrationId( this );
if( regId.equals( "" ) ) {
GCMRegistrar.register( this, GCM_SENDER_ID );
}
else {
Log.v( LOG_TAG, "Already registered" );
}
Context.enter(); //start Rhino
setupListeners();
}
#JSFunction
public void play() { document.querySelector("video").play(); }
#JSFunction
public void pause() { document.querySelector("video").pause(); }
private void setupListeners()
{
playButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
play();
}
});
pauseButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
pause();
}
});
}
#Override
protected void onStop() {
Context.exit(); //stop Rhino
super.onStop();
}
}
How do I continue from here?

First, since I'm writing in eclipse, and it sees no document variable, it produces an error. So how can eclipse recognize that element in the html page so I can compile and install the apk on the device?
answ: On your android device you just pass a message to the chrome browser. A.k. an action variable that is set to play or stop. You chrome app will then pick up the message and act accordingly. Also you can send the url as an variable in the message if you want to be able to play different urls.
Where do I specify the page url I want to communicate with? (send play/pause commands)?
answ: Do you already created the chrome app you want and verified it works? It should check with a google cloud server for messages. That server keeps track of the url for you.
To run js inside java I'm using Rhino. I looked through the examples in the documentation but I'm still not sure if a #JSFunction annotation is enough to declare a js function.?
answ: It seems you are misunderstanding the part what the android app does (sending the play action) and what the chrome browser does (actually playing the movie)
I hope my answer has helped a little, feedback is appreciated :)

Strange dialog with GooglePlayServicesUtil

I'm checking avalibility of google play services on device. I do it with these code:
final int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (resultCode != ConnectionResult.SUCCESS) {
final DialogInterface.OnCancelListener cancelListener = new DialogInterface.OnCancelListener() {
#Override
public void onCancel(final DialogInterface dialog) {
finish();
}
};
final Dialog errorDialog = GooglePlayServicesUtil.getErrorDialog(
resultCode, this, GOOGLE_PLAY_SERVICES_REQUEST_CODE, cancelListener
);
errorDialog.show();
}
I get resultCode = 2 (it's mean that Google Play Services needs to update). Dialog is shown, but instead of text, I get paths to layout.
It's looks like there are some interference of resource in app and resource in PlaYServices lib. But how it's possible and how to avoid id?

Since the accepted answer is somewhat unclear, I'll leave a signpost with my conclusions (mostly extracted from the comments on the question) which I believe are correct.
Short version: It seems that resource ids were incorrectly generated for this app.
It's obvious that the Google Play Services dialog intended to show strings in those places. The getErrorDialog() method is implemented like this (obfuscated, but the meaning can still be understood):
...
case 1:
return localBuilder.setTitle(R.string.common_google_play_services_install_title).create();
case 3:
return localBuilder.setTitle(R.string.common_google_play_services_enable_title).create();
case 2:
return localBuilder.setTitle(R.string.common_google_play_services_update_title).create();
...
Also, mistakenly doing something like getResources().getString(R.layout.my_layout) will return a string with the name of the original resource file ("res/layout/my_layout.xml").
So, we can conclude that, for some reason, the value of the Play Services Library resource, say, com.google.android.gms.R.string.common_google_play_services_install_title is actually the same as for the resource R.layout.dialog_share in the application project.
This probably stems for an incorrect build process, or an incorrect usage of the Google Play Services library (for example, including its jar directly, without the corresponding library process).

I have tested the code with google play service library version 4452000(use version >= 4452000). The code is as follows:
public class MainActivity extends Activity{
ProgressBar pBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (resultCode != ConnectionResult.SUCCESS) {
final DialogInterface.OnCancelListener cancelListener = new DialogInterface.OnCancelListener() {
#Override
public void onCancel(final DialogInterface dialog) {
finish();
}
};
final Dialog errorDialog = GooglePlayServicesUtil.getErrorDialog(
resultCode, this, 10, cancelListener
);
errorDialog.show();
}
}
}
Check your version of google play services and update if needed.

Here's the class I've been working on to check google play. It's not in production later this summer it will be so let me know with a comment if you have problems. It works tested on zten9120 and HTC EVO. The flow is like this. If static method isGooglePlay(context) returns false. Initialize the class and call the non static isgoogleplay() which will present the dialog to the user if googleplay services is not installed. The oncofigurationchange method handles when the device is rotated. onstop sets the class to null.
Modify three events in your activity.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (!MyGooglePlay.isGooglePlay(getApplicationContext())) {
myGP = new MyGooglePlay(this);
myGP.isGooglePlay();
}
#Override
public void onStop() {
super.onStop();
myGP = null;
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (myGP != null) {
if (myGP.errorFragment.isVisible()) {
myGP.errorFragment.dismissAllowingStateLoss();
}
}
}

Good Luck with getting google play services installed.

public static boolean isGooglePlayServiceAvailable(Context context) {
boolean isAvailable = false;
int result = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(context);
if (result == ConnectionResult.SUCCESS) {
Log.d(TAG, "Play Service Available");
isAvailable = true;
} else {
Log.d(TAG, "Play Service Not Available");
if (GooglePlayServicesUtil.isUserRecoverableError(result)) {
GooglePlayServicesUtil.getErrorDialog(result,
(Activity) context, PLAY_SERVICES_RESOLUTION_REQUEST)
.show();
} else {
Log.d(TAG, "Play Service Not Available");
GooglePlayServicesUtil.getErrorDialog(result,
(Activity) context, PLAY_SERVICES_RESOLUTION_REQUEST)
.show();
}
}
return isAvailable;
}

Updated answer : (as per GooglePlayServicesUtil.getErrorDialog is null)
If Google Play Services is not installed on the device, you may not be able to use the error dialog.
As per Rahim's comment in the above, you should only use the dialog if you have an "isUserRecoverableError" (his code):
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (status != ConnectionResult.SUCCESS) {
if (GooglePlayServicesUtil.isUserRecoverableError(status)) {
GooglePlayServicesUtil.getErrorDialog(status, this,
REQUEST_CODE_RECOVER_PLAY_SERVICES).show();
} else {
Toast.makeText(this, "This device is not supported.", Toast.LENGTH_LONG).show();
finish();
}
}
UPDATE - (from http://www.riskcompletefailure.com/2013/03/common-problems-with-google-sign-in-on.html)
One additional bug that surfaced quite a lot around the release of the latest version of Google Play Services was the onConnectionFailed method being called with a ConnectionResult which does not have a resolution, and has an error code of ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED.
As you might guess from the name, this indicates that the version of Google Play Services on the device is too low. Normally new versions will be updated automatically, but there is always a time delay in the roll out, so it is quite possible to get this error as updates are released.
You can handle this in the onConnectionFailed by calling getErrorDialog on GooglePlayServicesUtil, but the best way is to actually check whether Google Play Services is installed and up to date before even trying to connect. You can see a snippet of how to do this in the documentation.
So this is suggesting that this error (as you yourself say) should be recoverable, although note the clause that I have made bold. I am not convinced that this dialog would always be usable. Common sense suggests to me that this might depend on the version from which you were upgrading. So I recommend that you explicitly check that the error is marked as recoverable. If it is marked as recoverable then this looks like a bug in Google Play Services.

I found solution. I don't undertand why it's happening, but there is a solution.
I've built my project with maven and include a google play services framework as android library project.
Today, I've migrated to gradle and include dependecy go GPS with gradle and it solved my problem.

Any help is appreciated

Please init for MobileServiceClient mCLient; You just declare, not init. May be it is
mClient = new MobileServiceClient(...);
And with error:

just add library: GSON

Have you tried this solution.
Project Properties>Java Build Path>Order and Import tab and check the libraries you are using.
It seems that ADT update 22, you have to do this manually: Libraries do not get added to APK anymore after upgrade to ADT 22.

I think you didnot enter the appID and the server detail.
Below is the working code which i have implement and It works fine for me.
I have implement Pay on button click which extends the runnable
Check_out.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (_paypalLibraryInit) {
showPayPalButton();
//Toast.makeText(Android_PP_Test1Activity.this, captions[position], Toast.LENGTH_SHORT).show();
}
else {
// Display a progress dialog to the user and start checking for when
// the initialization is completed
Thread initThread = new Thread(initLibraryRunnable);
initThread.start();
_progressDialog = new ProgressDialog(Recharge.this);
_progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
_progressDialog.setMessage("Loading PayPal Payment Library");
_progressDialog.setCancelable(false);
_progressDialog.show();
_progressDialogRunning = true;
Thread newThread = new Thread(checkforPayPalInitRunnable);
newThread.start();
//Toast.makeText(Android_PP_Test1Activity.this, "Picasso Paintings", Toast.LENGTH_SHORT).show();
}
}
});
This button call this runnable method
//This lets us run the initLibrary function
final Runnable initLibraryRunnable = new Runnable() {
public void run() {
initLibrary();
}
};
and this method is responsible to initiate the initLibrary.
/** init method **/
public void initLibrary() {
PayPal pp = PayPal.getInstance();
if (pp == null) {
// This is the main initialization call that takes in your Context,
// the Application ID, and the server you would like to connect to.
pp=PayPal.initWithAppID(this,"APP80W284485P519543T",PayPal.ENV_SANDBOX);
// -- These are required settings.
pp.setLanguage("en_US"); // Sets the language for the library.
// --
// -- These are a few of the optional settings.
// Sets the fees payer. If there are fees for the transaction, this
// person will pay for them. Possible values are FEEPAYER_SENDER,
// FEEPAYER_PRIMARYRECEIVER, FEEPAYER_EACHRECEIVER, and
// FEEPAYER_SECONDARYONLY.
pp.setFeesPayer(PayPal.FEEPAYER_EACHRECEIVER);
// Set to true if the transaction will require shipping.
pp.setShippingEnabled(true);
// Dynamic Amount Calculation allows you to set tax and shipping
// amounts based on the user's shipping address. Shipping must be
// enabled for Dynamic Amount Calculation. This also requires you to
// create a class that implements PaymentAdjuster and Serializable.
pp.setDynamicAmountCalculationEnabled(false);
// --
}
}
Hope It helps...

The problem is when unity generates the apk file. I have compared one apk i made miself with PayPal integration only compiling with eclipse and other compiling with Unity.
Lets say the apk i made only with eclipse is called "PayPalOnlyEclipse.apk" and the one made with unity "PayPalWithUnity.apk"; y renamed them to "PayPalOnlyEclipse.zip" and "PayPalWithUnity.zip", then open both with WinRar to compare them.
I found that PayPalOnlyEclipse had one folder that PayPalWithUnity didn't, the folder is "com\paypal\android\utils\data". So I decompressed that folder and then added it to PayPalWithUnity. Then erase the META-INF folder (the signing), then close the "PayPalWithUnity.zip" and rename it like it was before ("PayPalWithUnity.apk").
Then I used the command for signing the apk file:
jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 -keystore my.keystore PayPalWithUnity.apk user
Finally I used the command for zipalign:
zipalign -v 4 PayPalWithUnity.apk PayPalWithUnity2.apk
that command generates PayPalWithUnity2.apk and that is the apk file you have to install in your phone.
Hope it helps, and sorry for my english.

Check if you have included the PaypalActivity on manifest file. Like this:
<activity android:name="com.paypal.android.MEP.PayPalActivity"
android:configChanges="keyboardHidden|orientation" />
If you have it and it doesnt work yet, include the library on the build path (Properties>>Java Buid Path>>Libraries>>Add JARs) and add it on the "order and export" tab (Properties>>Java Buid Path>>Order and Export).
