A way to prevent multiple instances of the same intent on button click in Android application

Sometimes while pressing a button repeatedly causes multiple instance of the same intent in android applications. To resolve this issue use intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) where you are creating the intent in your application, before starting the activity. Like below —

Intent intent = new Intent(this, YourClas.class);
startActivityForResult(intent, INTENT_ID);раскрутка сайтов в гугле самостоятельно бесплатно

AdWhirl integration in Android using xml layout

Integrating AdWhirl advertising is badly documented on AdWhirl support website. So, I have decided to share my experience here……

You can integrate AdWhirl very easily in your Android application as a provider following the steps below……

1. Register an account at AdWhirl

2. Add your application and the associated settings on the website

3. Download the AdWhirl sdk from the link

4. Add the sdk jar to your project build path

5. Add these parmissions to the menifest file

<uses-permission android:name=”android.permission.INTERNET” />
<uses-permission android:name=”android.permission.ACCESS_NETWORK_STATE” />
<uses-permission android:name=”android.permission.READ_PHONE_STATE” />
<uses-permission android:name=”android.permission.ACCESS_COARSE_LOCATION” />
<uses-permission android:name=”android.permission.ACCESS_FINE_LOCATION” />
<uses-permission android:name=”android.permission.WRITE_EXTERNAL_STORAGE” />

And this line of codes too for AdMob

<activity android:name=”com.google.ads.AdActivity”

6. Add this code to the  menifest file 

<meta-data android:value=”here goes the key” android:name=”ADWHIRL_KEY” />

in between the application tags


and replace the “here goes the key” with your AdWhirl sdk key.
7. Add this code


to the xml layout file just after


8. Add this code to the same android layout file


9. Add other ad networks “like AdMob, InMobi etc.” sdk jar files to your project build path too.

10. InMobi does not need any other coding, only it requires the sdk to be added.

11. Finally you may have to wait 3 or 4 days for your AdWhirl network to get the Ads. In the meantime the logcat may show fail errors.

12. I have successfully integrated AdMob and InMobi using these steps.индексация страниц в яндексе

Tips on How to install .apk files into the Android emulator (newer versions like android-sdk_r08-windows):

I am a Khulna University CSE Student and this is my blog…
