A wrapper around Android In-app Billing to make things stupidly easy (and not stupidly hard)

IJustWannaBuyThings

Sick of implementing raw Android In-app Billing APIs? Sick of using other developer's APIs that make heavy use of dependencies?

Me too.

Not the most suckiest Android In-app Billing wrapper

I can't guarantee that this is the most complete or advanced Android In-app Billing helper but it simply works for me - so suck it other helpers.

Note: This is only built for Android In-app Billing V3

More Note: Consumables and subscriptions are not included in this library yet

Setup

1. Download JAR into your Android project's libs directory - ijustwannabuythings-0.0.2.jar
2. Add <uses-permission android:name="com.android.vending.BILLING" /> to Manifest.xml
3. Copy IInAppBillingService.aidl into src/com.android.vending.billing

Subclassing IJustWannaBuyThingsActivity - (The easiest way)

• Key components for setting up - override these methods
  • onQueryAllTheThings(int responseCode, ArrayList responseList)
  • onBuyAThing(int responseCode, JSONObject purchasedData)
  • onWhatsMine(int responseCode, ArrayList ownedSkus, ArrayList purchaseDataList, ArrayList signatureList) {
• Key components for interacting
  • this.queryAllTheThings(Arrays.asList(new String[]{"bacon"}));
  • this.buyAThing("bacon");
  • this.whatsMine();

public class SubclassedActivity extends IJustWannaBuyThingsActivity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
	
	@Override
	public void onConnect() {}

	@Override
	public void onDisconnect() {}
	
	@Override
	public void onQueryAllTheThings(int responseCode, ArrayList<JSONObject> responseList) {
		Log.d("IJustWannaBuyThings", Arrays.toString(responseList.toArray()));
	}


	@Override
	public void onBuyAThing(int responseCode, JSONObject purchasedData) {
		 Log.d("IJustWannaBuyThings", purchasedData.toString());
	}


	@Override
	public void onWhatsMine(int responseCode, ArrayList<String> ownedSkus, ArrayList<JSONObject> purchaseDataList, ArrayList<String> signatureList) {
		Log.d("IJustWannaBuyThings", Arrays.toString(ownedSkus.toArray()));
	}
	
	
	/**
	 * An onClick handler to show all products
	 * @param view
	 */
	public void onClickShowMeThings(View view) {
		// Queries information about the supplied skus
		this.queryAllTheThings(Arrays.asList(new String[]{"bacon"}));
	}
	
	/**
	 * An onClick handler to buy a bacon
	 * @param view
	 */
	public void onClickBuyMeBacon(View view) {
		// Starts the purchase for a sku
		this.buyAThing("bacon");
	}
	
	/**
	 * An onClick get what I bought
	 * @param view
	 */
	public void onClickWhatsMine(View view) {
		// Starts request to get whats mine
		this.whatsMine();
	}

}

Implementing in your own Activity

• Key components for setting up
  • iJustWannaBuyThings = new IJustWannaBuyThings(this, listener);
  • iJustWannaBuyThings.onCreate();
  • iJustWannaBuyThings.onActivityResult(requestCode, resultCode, data);
  • iJustWannaBuyThings.onDestroy();
• Key components for interacting
  • iJustWannaBuyThings.queryAllTheThings(Arrays.asList(new String[]{"bacon"}));
  • iJustWannaBuyThings.buyAThing("bacon");
  • iJustWannaBuyThings.whatsMine();

public class CustomActivity extends Activity {

	private IJustWannaBuyThings iJustWannaBuyThings;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		iJustWannaBuyThings = new IJustWannaBuyThings(this, listener);
