I've been struggling with this problem for days now. I know there are a lot of questions with the same problem on SO but i couldn't get it to work.
What I have done
Code
AndroidManifest.xml
<uses-permission android:name="com.android.vending.BILLING" />
MainActivity.java
public class MainActivity extends AppCompatActivity {
private IabHelper mHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ...
setupInAppBillings();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
// [....]
private void setupInAppBillings() {
String base64EncodedPublicKey = "MY PUBLIC KEY";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Toast.makeText(getContext(), "In-app Billing setup failed: " + result, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), "In-app Billing is set up OK", Toast.LENGTH_SHORT).show();
}
}
});
}
}

What I've tried
The only thing I haven't done from this list is the setup of the License Verification Library (LVL). But I couldn't find any information that this step is required for an In-App Purchase. If not needed I want to do it without this library because I don't really need it as stated on the Google Site.
The Google Play Licensing service is primarily intended for paid applications that wish to verify that the current user did in fact pay for the application on Google Play.
Is there something I miss?
Finally I got it to work! The problem was the following: Even though I put the IInAppBillingService.aidl
in the com.android.vending.billing
package, the generated class was in the wrong package as you can see in the code below.
/*
* This file is auto-generated. DO NOT MODIFY.
* Original file: C:\\path\\src\\main\\aidl\\com\\android\\vending\\billing\\IInAppBillingService.aidl
*/
package billing;
public interface IInAppBillingService extends android.os.IInterface { //... }
To solve this, I deleted and recreated the com.android.vending.billing
package with the IInAppBillingService.aidl
. So if you have the same problem, check twice where the IInAppBillingService.java
was generated.
if you target android 31 you should add this to your manifest :
<queries>
<intent>
<action android:name="android.intent.action.MAIN" />
</intent>
</queries>
I recently faced this problem. As Bona Fide wrote, the package declaration in IInAppBillingService.aidl must be set to "com.android.vending.billing" and the aidl file should be found inside the corresponding directory using the explorer. Furthermore (and that was the problem in my case), in the IabHelper.java, the string parameter to serviceIntent must be the same as the package name that contains the IInAppBillingService.aidl file.
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");// correct package name: com.android.vending.billing
serviceIntent.setPackage("com.android.vending");
List<ResolveInfo> intentServices = mContext.getPackageManager().queryIntentServices(serviceIntent, 0);
if (intentServices != null && !intentServices.isEmpty()) {
// service available to handle that Intent
mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
// no service available to handle that Intent
if (listener != null) {
listener.onIabSetupFinished(
new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
"Billing service unavailable on device."));
}
}
}
