我刚刚在我的应用中实现了应用内结算功能。 我只有一种产品可以解锁所有高级功能 购买本身有效，但在购买流程之后，我的代码显然无法识别购买成功，因为购买后出现了一个抱怨窗口，说明＆＃34; Articel已经拥有＆＃34 ; 即可。因此，某种程度上购买流程并未被认为是成功的。重新启动应用程序后，专业版功能已解锁，因为查询库存说明，专业版功能已被购买。 我没有想法，所以这是我的代码：
// SKUs for our products: the premium upgrade (non-consumable)
字符串SKU_PREMIUM;
// (arbitrary) request code for the purchase flow
final int RC_REQUEST = 10001;
// The helper object
IabHelper mHelper;
// Provides purchase notification while this app is running
public IabBroadcastReceiver mBroadcastReceiver;
IabHelper.QueryInventoryFinishedListener mGotInventoryListener;
AppCompatActivity activity;
private String payload;
public InAppBillingHelper(AppCompatActivity context, final IabBroadcastReceiver.IabBroadcastListener contextBroadcastListener, String base64EncodedPublicKey,String skuPremium, boolean debug){
//String base64EncodedPublicKey = "VALENTIN_HERR_SCHAFKOPF_RECHENHELFER";
this.activity = context;
SKU_PREMIUM = skuPremium;
// Create the helper, passing it our context and the public key to verify signatures with
Log.d(TAG, "Creating IAB helper.");
mHelper = new IabHelper(context, base64EncodedPublicKey);
// enable debug logging (for a production application, you should set this to false).
mHelper.enableDebugLogging(debug);
// Start setup. This is asynchronous and the specified listener
// will be called once setup completes.
Log.d(TAG, "Starting setup.");
// Listener that's called when we finish querying the items and subscriptions we own
mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// Is it a failure?
if (result.isFailure()) {
complain("Fehler bei der Bestimmung der App-Lizenz: " + result);
// TODO analyse results and output it to the user
return;
}
Log.d(TAG, "Query inventory was successful.");
// Do we have the premium upgrade?

mIsPremium = (premiumPurchase != null && verifyDeveloperPayload(premiumPurchase));

顺便说一下：代码是**普通驱动器*示例的修改版本。 提前谢谢！

虽然这不是最干净的解决方案，但如果您有“已经拥有的错误”，请再次查询库存。然后，仅根据库存查询结果

谢谢@DerAdler。我按照你说的方式实现它，并且它有效。
