我正在做一個應用程序，它可以讓你購買它的「高級版本」，在我的手機中它工作正常，但在另一個手機當用戶點擊一個按鈕時（在一個活動中）此消息出現：我有我的android應用程序的幾個問題，如何解決它？
應用不幸已經停止
這是onCreate()方法的代碼。我想問題在那裏，但我不知道如何解決它。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_selector);
Bundle s = getIntent().getExtras();
int x = s.getInt("day");
int y = s.getInt("month");
int z = s.getInt("year");
String base64EncodedPublicKey = "MY GOOGLE ID"
mHelper = new IabHelper(this, base64EncodedPublicKey);
// compute your public key and store it in base64EncodedPublicKey
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.d(TAG, "Problem setting up In-app Billing: " + result);
}
Log.d(TAG, "Setup successful. Querying inventory.");
try {
mHelper.queryInventoryAsync(false,mGotInventoryListener);
} catch (IabHelper.IabAsyncInProgressException e) {
e.printStackTrace();
}
// Hooray, IAB is fully set up!
}
});
}
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
if (result.isFailure()) {
alert("Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
// Do we have the premium upgrade?
mIsPremium = inventory.hasPurchase(SKU_PREMIUM);
if(mIsPremium)
{
updateUi();
}
Log.d(TAG, "User is " + (mIsPremium ? "PREMIUM" : "NOT PREMIUM"));
Log.d(TAG, "Initial inventory query finished; enabling main UI.");
}
};
這是logat：
