Admob with padding
Aug 26th
I just added AdMob to my Android app DRoute and it doesn’t work. I receive many calls to onFailedToReceiveAd event function
-
@Override
-
public void onFailedToReceiveAd(AdView adView)
-
{
-
Log.d("DRoute", "onFailedToReceiveAd");
-
super.onFailedToReceiveAd(adView);
-
}
I dig into the problem, search on the internet and didn’t found a solution. This morning I’ve created step by step a fresh new app only to test AdMob publisher code and ID and it works fine on emulator with :

Install/Move to sd card on Froyo
Aug 5th
On Froyo ( Android 2.2 ) the user have the option to move / install applications to sd card. This is good due to lack of space on phone memory.
To enable this option at application level the developer should do some simple modifications.
- Open manifest file ( AndroidManifest.xml ).
- Add android:installLocation=”auto” as attributes to your root manifest element. Here you have 3 options :
internalOnly: Install the application on internal storage only. This will result in storage errors if the device runs low on internal storage.preferExternal: The android system tries to install the application on external storage. If that is full, the application is installed on internal storage.auto: Let the Android system decide the best install location for the application. The default system policy is to install the application on internal storage first. If the system is running low on storage, the application is then installed on external storage.
- Change Project Build Target to Android 2.2
- Keep android:minSdkVersion as low as you want. This new option will be available only on devices running Froyo (2.2)

Services – connect and communicate using aidl
Jul 31st
With services there are 2 ways to work with :
- One is to use startService(Intent) to start the service and stopService(Intent) to stop the service from within your activity. With this solution you cannot communicate directly with the service, but you can use SQLITE as a layer between activities and services.
- The second is to use bindService() to bind the service with the activity. With this the service is alive all the time the activity that is bind to is alive. With this method you can communicate with the service directly.
I will write a simple tutorial about the second option.
I use Eclipse and ADT Plugin for Eclipse . This will do some background work.
