我正在尝试进行不适用的演示.我按照本教程学习这个.

Lemme告诉我执行此任务所遵循的步骤

1. 我使用了下面提到的代码

   package com.ohn.inappbilling;
   
   import android.content.Intent;
   import android.os.Bundle;
   import android.support.v7.app.ActionBarActivity;
   import android.util.Log;
   import android.view.View;
   import android.widget.Button;
   
   import com.hello.inappbilling.util.IabHelper;
   import com.hello.inappbilling.util.IabResult;
   import com.hello.inappbilling.util.Inventory;
   import com.hello.inappbilling.util.Purchase;
   import com.ohn.inappbilling.R;
   
   public class MainActivity extends ActionBarActivity {
   
   private static final String TAG = "com.hello.inappbilling";
   static final String ITEM_SKU = "com.buttonclick";
   IabHelper mHelper;
   private Button clickButton;
   private Button buyButton;
   
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       buyButton = (Button) findViewById(R.id.buyButton);
       clickButton = (Button) findViewById(R.id.clickButton);
       clickButton.setEnabled(false);
       String base64EncodedPublicKey = "******";
   
       mHelper = new …

我正在使用asmack和xmpp进行文件共享.我能够发送文件,但无法在另一台设备上接收文件.我做了很多研究和开发,发现很多方法尝试了所有这些但没有取得成功.似乎我犯了任何小错误,尝试了很多,但没有解决我的问题.我用来发送文件的代码是:

d.findViewById(R.id.btnsendphoto).setOnClickListener(
                    new OnClickListener() {

                        @Override
                        public void onClick(View v) {
                            // TODO Auto-generated method stub
                            if (!filepath.equals("")) {

                                configureProviderManager(connection);
                                FileTransferNegotiator.IBB_ONLY = true;
                                FileTransferNegotiator.setServiceEnabled(
                                        connection, true);
                                mFileTransferManager = new FileTransferManager(
                                        connection);

                                String to = connection.getRoster()
                                        .getPresence("cac6ba9dc9c6ac67@pc")
                                        .getFrom();
                                final OutgoingFileTransfer transfer = mFileTransferManager
                                        .createOutgoingFileTransfer(to);
                                File file = new File(filepath);

                                try {
                                    configureProviderManager(connection);
                                    transfer.sendFile(file, "test_file");
                                } catch (XMPPException e) {
                                    e.printStackTrace();
                                }
                                new AsyncTask<Void, Void, Void>() {

                                    protected void onPreExecute() {

                                    }
