我只是用android打開貝寶，一切都OK，但如果我從統一調用，這是發生！這是我的java代碼：PayPal.initWithAppID（）崩潰與空指針異常

package com.paypal.androidpets;

import android.content.Context; 
import android.os.Handler; 

import com.lonfun.pets.UnityPayMenuActivity; 
import com.paypal.android.MEP.PayPal; 
import com.paypal.android.MEP.PayPalActivity; 

public class PaypalTool { 
    Context context; 
    PayPal pp; 
    private static final int server = PayPal.ENV_SANDBOX; 
    // The ID of your application that you received from PayPal 
    private static final String appID = "APP-80W284485P519543T"; 

    public PaypalTool(Context context) { 
     this.context=context; 
    } 

    public void initLibrary(final Handler handler) 
    { 
     new Thread() { 
      public void run() { 
       PayPalActivity._paypal = null; 
       pp = PayPal.getInstance(); 
       // If the library is already initialized, then we don't need to initialize it again. 
       if(pp == null) { 
//     pp = PayPal.initWithAppID(context, "", PayPal.ENV_NONE); 
        pp = PayPal.initWithAppID(context, appID, server); 

        pp.setShippingEnabled(false); 
       } 

       if (PayPal.getInstance().isLibraryInitialized()) { 
        handler.sendEmptyMessage(0); 
       } 
       else { 
        handler.sendEmptyMessage(1); 
       } 
      } 
     }.start(); 
    } 
}

請問您可以上傳完整的代碼片段嗎？ – Raynold 2013-03-20 09:56:16

private static final int server = PayPal。ENV_SANDBOX; \t //您從PayPal收到的應用程序ID private static final String appID =「APP-80W284485P519543T」;我之前定義過， – 2013-03-20 11:42:58

我添加完整的代碼，如果我編寫一個使用paypal的android應用程序，它運行良好，但從Unity3D調用PaypalTool，然後崩潰allways， – 2013-03-20 11:53:51

我想你沒有輸入appID和服務器的詳細信息。下面是我已經實現的工作代碼，它適用於我。我有實現它擴展了可運行

Check_out.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 

      if (_paypalLibraryInit) { 
     showPayPalButton(); 
     //Toast.makeText(Android_PP_Test1Activity.this, captions[position], Toast.LENGTH_SHORT).show(); 

     } 
      else { 
      // Display a progress dialog to the user and start checking for when 
     // the initialization is completed 


      Thread initThread = new Thread(initLibraryRunnable); 
      initThread.start(); 

      _progressDialog = new ProgressDialog(Recharge.this); 
     _progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); 
     _progressDialog.setMessage("Loading PayPal Payment Library"); 
     _progressDialog.setCancelable(false); 
     _progressDialog.show(); 
     _progressDialogRunning = true; 
     Thread newThread = new Thread(checkforPayPalInitRunnable); 

     newThread.start(); 
     //Toast.makeText(Android_PP_Test1Activity.this, "Picasso Paintings", Toast.LENGTH_SHORT).show(); 


     } 
    } 


});

該按鈕來調用此方法可運行

//This lets us run the initLibrary function 
    final Runnable initLibraryRunnable = new Runnable() { 
     public void run() { 
      initLibrary(); 
     } 
    };

按鈕點擊付費，這方法負責啓動initLibrary。

/** init method **/ 
public void initLibrary() { 
    PayPal pp = PayPal.getInstance(); 
    if (pp == null) { 
     // This is the main initialization call that takes in your Context, 
     // the Application ID, and the server you would like to connect to. 
     pp=PayPal.initWithAppID(this,"APP80W284485P519543T",PayPal.ENV_SANDBOX); 

     // -- These are required settings. 
     pp.setLanguage("en_US"); // Sets the language for the library. 
     // -- 

     // -- These are a few of the optional settings. 
     // Sets the fees payer. If there are fees for the transaction, this 
     // person will pay for them. Possible values are FEEPAYER_SENDER, 
     // FEEPAYER_PRIMARYRECEIVER, FEEPAYER_EACHRECEIVER, and 
     // FEEPAYER_SECONDARYONLY. 
     pp.setFeesPayer(PayPal.FEEPAYER_EACHRECEIVER); 
     // Set to true if the transaction will require shipping. 
     pp.setShippingEnabled(true); 
     // Dynamic Amount Calculation allows you to set tax and shipping 
     // amounts based on the user's shipping address. Shipping must be 
     // enabled for Dynamic Amount Calculation. This also requires you to 
     // create a class that implements PaymentAdjuster and Serializable. 
     pp.setDynamicAmountCalculationEnabled(false); 
     // -- 


    } 
}

希望它可以幫助...

問題是，當統一生成APK文件。我比較了一個apk，我把miself和PayPal整合在一起，只用eclipse和其他Unity編譯來編譯。假設我只用eclipse製作的apk文件名爲「PayPalOnlyEclipse.apk」，而用統一的「PayPalWithUnity.apk」製作的apk文件名爲「PayPalOnlyEclipse.apk」。 y將它們重命名爲「PayPalOnlyEclipse.zip」和「PayPalWithUnity.zip」，然後使用WinRar打開它們進行比較。

我發現PayPalOnlyEclipse有一個PayPalWithUnity沒有的文件夾，文件夾是「com \ paypal \ android \ utils \ data」。所以我解壓縮該文件夾，然後將其添加到PayPalWithUnity。然後清除META-INF文件夾（簽名），然後關閉「PayPalWithUnity.zip」並重命名爲之前的版本（「PayPalWithUnity.apk」）。

然後我用命令簽署apk文件：的jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 -keystore my.keystore PayPalWithUnity.apk用戶

最後我用的zipalign命令：的zipalign -v 4 PayPalWithUnity.apk PayPalWithUnity2.apk

該命令生成PayPalWithUnity2.apk，這是你必須安裝在手機中的apk文件。

希望它有幫助，對不起我的英語。

檢查您是否在清單文件中包含了PaypalActivity。就像這樣：

<activity android:name="com.paypal.android.MEP.PayPalActivity" 
     android:configChanges="keyboardHidden|orientation" />

如果你有它，它不工作還沒有，包括構建路徑（屬性>> Java的打造專業化路徑>>圖書館>>添加JAR文件），並添加它的「命令和庫導出「選項卡（屬性>> Java Buid路徑>>訂單和導出）。
