他に完成したアプリでアプリ内購入を実装しようとすると重大な問題が発生します。 BaseActivityというクラスがあり、他のすべてのクラスが拡張されています。これは、私のツールバー、ナビドロワー、およびIabHelperが設定されている場所です。Androidアプリ内購入問題
BaseActivity.java：
public abstract class BaseActivity extends AppCompatActivity implements IabBroadcastReceiver.IabBroadcastListener{
public boolean m30paid = false;
public boolean m31paid = false;
public boolean m32paid = false;
public boolean m37paid = false;
static final String ITEM_SKU = "android.test.purchased";
IabHelper mHelper;
IabBroadcastReceiver mBroadcastReceiver;
private final String LOG = BaseActivity.class.getSimpleName();
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String base64EncodedPublicKey = "********KEY HERE*********";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d(LOG, "Problem setting up in app billing: " + result);
}
else Log.d(LOG, "set up correctly!");
if (mHelper == null) return;
}
});
mBroadcastReceiver = new IabBroadcastReceiver(this);
IntentFilter broadcastFilter = new IntentFilter(IabBroadcastReceiver.ACTION);
registerReceiver(mBroadcastReceiver, broadcastFilter);
//IAB fully set up, query inventory
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data)
{
if (!mHelper.handleActivityResult(requestCode,
resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
@Override
public void onDestroy() {
super.onDestroy();
// very important:
if (mBroadcastReceiver != null) {
unregisterReceiver(mBroadcastReceiver);
}
// very important:
Log.d(LOG, "Destroying helper.");
if (mHelper != null) {
mHelper.disposeWhenFinished();
mHelper = null;
}
}
@Override
public void receivedBroadcast() {
}
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(LOG, "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("Failed to query inventory: " + result);
return;
}
Log.d(LOG, "Query inventory was successful.");
/*
* Check for items we own. Notice that for each purchase, we check
* the developer payload to see if it's correct! See
* verifyDeveloperPayload().
*/
}};
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(LOG, "Purchase finished: " + result + ", purchase: " + purchase);
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
if (result.isFailure()) {
complain("Error purchasing: " + result);
return;
} else if (purchase.getSku().equalsIgnoreCase("workout_30")) {
m30paid = true;
}
Log.d(LOG, "Purchase successful.");
}
};
void alert(String message) {
AlertDialog.Builder bld = new AlertDialog.Builder(this);
bld.setMessage(message);
bld.setNeutralButton("OK", null);
Log.d(LOG, "Showing alert dialog: " + message);
bld.create().show();
}
public void complain(String message) {
Log.e(LOG, "**** TrivialDrive Error: "+ message);
alert("Error: " + message);
}
そこから、私は別のクラスにボタンのクリックでlaunchPurchaseFlowを設定してみてください。
Purchases.java：
public class purchases extends BaseActivity {
IabHelper mHelper;
static final String ITEM_SKU = "android.test.purchased";
IabBroadcastReceiver mBroadcastReceiver;
Context mContext;
Activity mActivity = this;
static final int RC_REQUEST = 10001;
private Button btn30;
static final String SKU_W30 = "workout_30";
String payload = "";
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.purchases);
mToolBar = activateToolbar();
setUpNavigationDrawer();
getSupportActionBar().setTitle("Purchases");
btn30 = (Button) findViewById(R.id.btn30);
Button btn31 = (Button) findViewById(R.id.btn31);
Button btn32 = (Button) findViewById(R.id.btn32);
Button btn37 = (Button) findViewById(R.id.btn37);
btn30.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
mHelper.launchPurchaseFlow(purchases.this, SKU_W30, RC_REQUEST, mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
complain("Error");
}
}
});
}
}
私はボタンをクリックしたときに、私は取得していますエラーは次のとおりです。

は基本的に私はそれが何をしたいのかブール値を変更、onIabPurchaseFinishedであります値をtrueに設定します。私は私のexpLV上のifステートメントを持っているので、ブール値がfalseの場合、これを購入する必要があると言います。もしそうなら、それはアクセス権を与えます。これまでのところ、この部分は正常に動作していますが、このエラーを超えて、ブール値が正しく変更され、データのロックが解除されているかどうかを確認できません。
私は何が不足しているのか分かりません。私はそれをやめて、2日間複数のエラーを処理しています。
Googleのコンソールに下書きをアップロードしただけの場合は、このようなことが起こりますか？実際に動作させるためのベータテストを公開しなければなりませんか？ – LBJ33
