I advise you to convert all your date into timestamp and use only timestamp for comparaison (you can also save date as timestamp in your database) :
System.currentTimeMillis() // Current timestamp
date.time // timestamp of the SQL Date object
if (timestamp1 > timestamp2) {
// timestamp1 after timestamp2
} else if (timestamp1 < timestamp2) {
// timestamp1 before timestamp2
} else {
// timestamp1 == timestamp2
}

Try this code first convert data into this format..."dd/mm/yyyy"
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date strDate = sdf.parse(valid_until);
if (new Date().after(strDate)) {
// define log
}

In App Purchases - How to handle the second click?

i just want to implement in-app-purchasement into my app. It is a card game with different rulesets. So now want to implement 2 new rulesets which should work as my products and with in-app-purchasement.
I have this:
`go = (Button)findViewById(R.id.go);
go.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ArrayList skuList = new ArrayList();
skuList.add(inappid);
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
Bundle skuDetails;
try {
skuDetails = mservice.getSkuDetails(3, getPackageName(),
"inapp", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> responseList =
skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList) {
JSONObject object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
if (sku.equals(inappid)) {
System.out.println("price " + price);
Bundle buyIntentBundle =
mservice.getBuyIntent(3, getPackageName(), sku,
"inapp",
"blablabla");
PendingIntent pendingIntent =
buyIntentBundle.getParcelable("BUY_INTENT");
startIntentSenderForResult(
pendingIntent.getIntentSender(), 1001,
new Intent(), Integer.valueOf(0),
Integer.valueOf(0), Integer.valueOf(0));
}
}
}
} catch (RemoteException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} catch (IntentSender.SendIntentException e ) {
e.printStackTrace();
}
}
});`
First click on my ruleset works fine. The second click triggers the app to break down with the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.IntentSender android.app.PendingIntent.getIntentSender()' on a null object reference
Do you have some good in-app tutorials or a tipp for me?
Thanks in advance

Here is my BaseClass that i use everywhere i need. Just extend your activity by this BaseInAppPurchaseActivity
Bonus in this class.
You can get what items are available for purchase so user can not get future exception if item is not available like
checkAvailablePurchases(skuList, new OnResultInApp() {
#Override
public void onResult(ArrayList<AvailablePurchase> availablePurchaseArrayList) {
.. logic for showing view with available purchaseItem
}
});
For purchasing an item
purchaseItem(googleInAppId, new OnResultPurchase() {
#Override
public void onSuccess(PurchaseResponseBean purchaseResponseBean, String inAppPurchaseData) {
// your stuff
}
#Override
public void onError() {
showToast(R.string.something_went_wrong);
}
});
Isn't this look pretty clean and nice.

I want to stop the my background service. When i open my application again

Here is my activity. I am started the service i.e SeviceToStartBackgroundService.class from HomeActivity . Here i want to check whether services are running or not if running then i want to stop the services.
package com.example.tracker.activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;

int i=1;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
}
#Override

super.onResume();
stopServiceMethod();
startService(new Intent(getApplicationContext(),SeviceToStartBackgroundService.class));
}
public void stopServiceMethod(){
Log.e(TAG,"stopServiceMethod()");

stopService(new Intent(this, SeviceToStartBackgroundService.class));
stopService(new Intent(this, BluetoothLeService.class));
stopService(new Intent(this, BLEService.class));
}
}
Here is my SeviceToStartBackgroundService.class . When i removed the app from recent apps then the onTaskRemoved(Intent rootIntent) method gets called. And one more service gets started i.e BackgroundService.class.
package com.example.tracker.service;
import android.app.Service;

Log.e(getClass().getName(), "App just got removed from Recents!");
startService(new Intent(getApplicationContext(),BackgroundService.class));
}
#Override
public void onDestroy() {
super.onDestroy();
}
}
Here is my BackgroundService.class . I want to stop this service when app comes in user interaction (front end) .

Android Methods: Method 1 returns empty String value with error and Method 2 returns a null pointer exceptions

Can someone help me to see what is wrong with these two functions
Method 1 returns empty String value without any error and Method 2 returns a null pointer exceptions
I have tried all the similar examples I could find here but still have issues for days. Thanks in advance.
//Funtion1 Converting File to Base64.encode String type but returns empty string
public String getStringFile(File f) {

String encodedFile= "", lastVal;
try {

inputStream = new FileInputStream(f);
byte[] buffer = new byte[10240];//specify the size to allow
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
Base64OutputStream output64 = new Base64OutputStream(output, Base64.DEFAULT);
while ((bytesRead = inputStream.read(buffer)) != -1) {
output64.write(buffer, 0, bytesRead);
}
output64.close();
encodedFile = output64.toString();
}
catch (FileNotFoundException e1 ) {

}
catch (IOException e) {

}
Log.i("Base64 String", "=" + encodedFile);
Log.v("Base64 String", "=" + encodedFile);
Log.e("Base64 String", "=" + encodedFile);
lastVal = encodedFile;
return lastVal;
}
// Funtion 2 also Converting File to Base64 encode String but returns NullPointerException

I noticed the particular function that was returning a null value was the right function then I decided to know why it was returning null value.
I decided to declare the following object and value type variables globally and then initialized them in the onCreate() method.
InputStream inputStream = null ;
ByteArrayOutputStream output = null;
Base64OutputStream output64 = null;
byte[] buffer;
int bytesRead;
String encodedFile;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
buffer = new byte[10240];//specify the size to allow
output = new ByteArrayOutputStream();
output64 = new Base64OutputStream(output, Base64.DEFAULT);
encodedFile = output64.toString();
}
public String getStringFile(File f) {
InputStream inputStream = null;
try {
//Please remember that filePath2 is an object of Uri
String uriString = filePath2.toString();
f = new File(uriString).getAbsoluteFile();
inputStream = new FileInputStream(f);
while ((bytesRead = inputStream.read(buffer)) != -1) {
output64.write(buffer, 0, bytesRead);
}
output64.close();
encodedFile = output64.toString();
}
catch (FileNotFoundException e1 ) {
e1.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
return encodedFile;
}
Finally, Let's take note that variables (i.e. value or object type variables) declared globally that are expected to be accessed severally within the activity class should be initialized in the onCreate Method for them to return their values at any point of the class that it will be called except otherwise we want to re-initialize them for a different values.

Qr scanner scanned result in fragment

I am beginner to android..I integrated qr scanner ZXING library in my app..in fragment layout..this library working..On click button..qr scanner is opening..but scanned result is not displaying inside edit text in fragment layout..how to display result in fragment?
below is my On click button code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = null;
view = inflater.inflate(R.layout.configure_switch,container,false);
button = (Button)view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(getActivity());
integrator.initiateScan();
}
});

it's simple. after getting scanned result, you need to put the following code.
YourEditTextName.setText(ResultText);

Happy coding.!!!

when you receive the result to a activity get the current fragment and call that method like below
CustomFragmentClass will be your fragment.
Fragment fragment = getActivity().getFragmentManager().findFragmentById(R.id.fragment_container);
if (fragment instanceof CustomFragmentClass){
fragment.onActivityResult(int requestCode, int resultCode, Intent data);
}
or you can also refer this onActivityResult is not being called in Fragment
