Google In-App billing, IllegalArgumentException: Service Intent must be explicit, after upgrading to Android L Dev Preview

My in-app billing code was working fine until I upgraded to the Android L Dev Preview. Now I get this error when my app starts. Does anyone know what's changed about L that causes this or how I should change my code to fix this?

android {
compileSdkVersion 'android-L'
buildToolsVersion '20'
defaultConfig {
    minSdkVersion 13
    targetSdkVersion 'L'
...
...


compile 'com.google.android.gms:play-services:5.+'
compile 'com.android.support:support-v13:21.+'
compile 'com.android.support:appcompat-v7:21.+'
...
...

The error when the app starts:

Solution 1:

I had the same problem and explicitly setting the package solved it. Similar to Aleksey's answer, but simpler:

Intent intent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
// This is the key line that fixed everything for me
intent.setPackage("com.android.vending");

getContext().bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);

Solution 2:

As pointed out in answer below, solutions would be to create explicit intent manually:

private Intent getExplicitIapIntent() {
        PackageManager pm = mContext.getPackageManager();
        Intent implicitIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
        List<ResolveInfo> resolveInfos = pm.queryIntentServices(implicitIntent, 0);

        // Is somebody else trying to intercept our IAP call?
        if (resolveInfos == null || resolveInfos.size() != 1) {
            return null;
        }

        ResolveInfo serviceInfo = resolveInfos.get(0);
        String packageName = serviceInfo.serviceInfo.packageName;
        String className = serviceInfo.serviceInfo.name;
        ComponentName component = new ComponentName(packageName, className);
        Intent iapIntent = new Intent();
        iapIntent.setComponent(component);
        return iapIntent;
    }

Here is the code in L preview sources for check explicit intent. It's got commented currently, but on Nexus 5 with L preview it still runs and throws exception for implicit intents.

Edit: @alav's answer is much more better and simpler. Just add

intent.setPackage("com.android.vending");

All credits for him. And here is the code in L release sources for check explicit intent.

Solution 3:

Found clear solution here: https://code.google.com/p/android-developer-preview/issues/detail?id=1674

In Google Licensing Library (LVL), LicenseChecker.java file, replace "bindService" call with this:

 Intent serviceIntent = new Intent(
         new String(Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")));
         serviceIntent.setPackage("com.android.vending");

     boolean bindResult = mContext
             .bindService(
               serviceIntent,
               this, // ServiceConnection.
               Context.BIND_AUTO_CREATE);

AND in the AndroidManifest.xml set: android:minSdkVersion="4"

The "setPackage" requires Android version 4.
