我正在尝试让我的应用下载扩展文件。这是我的主要内容：

package tm.down.rob;

import com.google.android.vending.expansion.downloader.DownloadProgressInfo;
import com.google.android.vending.expansion.downloader.DownloaderClientMarshaller;
import com.google.android.vending.expansion.downloader.Helpers;
import com.google.android.vending.expansion.downloader.IDownloaderClient;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.os.Messenger;
import android.util.Log;
import android.widget.ProgressBar;
import android.widget.TextView;

public class main extends Activity implements IDownloaderClient {
    /** Called when the activity is first created. */

    TextView tv1;

    @Override
     public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      //////////
      tv1 = (TextView)findViewById(R.id.textView1);
      //////////

      // Check whether the file have been downloaded.
      String mainFileName = Helpers.getExpansionAPKFileName(this, true, 1);
      boolean fileExists = Helpers.doesFileExist(this, mainFileName, 32921796L, false);

      if (!fileExists) {
       Intent launcher = getIntent();
       Intent fromNotification = new Intent(this, getClass());
       fromNotification.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
       fromNotification.setAction(launcher.getAction());

       if (launcher.getCategories() != null) {
        for (String cat : launcher.getCategories()) {
         fromNotification.addCategory(cat);
        }
       }

       PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, fromNotification, PendingIntent.FLAG_UPDATE_CURRENT);

       try {

        int result = DownloaderClientMarshaller.startDownloadServiceIfRequired( this, pendingIntent, ExpansionFileDownloaderService.class);
        if (DownloaderClientMarshaller.NO_DOWNLOAD_REQUIRED != result) {

            // implement Downloading UI.
            tv1.setText("Need to download.");

         return;
        }

       } catch (Exception e) { 
        Log.e("apk-expansion-files", "NameNotFoundException occurred. " + e.getMessage(), e);
       }
      }

      tv1.setText("Downloaded!");

     }


    ///////////////////////////////////////////////////


    @Override
    public void onServiceConnected(Messenger m) {
        tv1.setText("onServiceConnected: " + m.toString() );
    }

    ///////////

    @Override
    public void onDownloadStateChanged(int newState) {
        tv1.setText("onDownloadStateChanged: " + String.valueOf(newState) );
    }

    ////////////

    @Override
    public void onDownloadProgress(DownloadProgressInfo progress) {
        ProgressBar mPB = (ProgressBar)findViewById(R.id.progressBar1);

        progress.mOverallTotal = progress.mOverallTotal;
        mPB.setMax((int) (progress.mOverallTotal >> 8));
        mPB.setProgress((int) (progress.mOverallProgress >> 8));
        //mProgressPercent.setText(Long.toString(progress.mOverallProgress * 100 / progress.mOverallTotal) + "%");
        //mProgressFraction.setText(Helpers.getDownloadProgressString(progress.mOverallProgress,progress.mOverallTotal));

    }

    ////////////




}

我编译了 apk 并将其上传到标记，并使用重命名为main.1.tm.down.rob.obb的 zip 文件，但是当我运行我的应用程序时，它仍然向我抛出“下载失败，因为找不到资源” ...

有任何想法吗？谢谢！

当我尝试使用使用https://github.com/mosabua/maven-android-sdk-deployer部署到我的 Maven 存储库的下载器库 apklib+jar 时遇到了同样的问题

当我使用这个 Gradle 构建脚本将下载器库重新部署到我的 Maven 存储库时：

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'com.android.tools.build:gradle:0.11.+'
  }
}

apply plugin: 'android-library'
apply plugin: 'maven'

repositories {
  maven {
    url "http://repository_url/nexus/content/repositories/release"
  }
  maven {
    url "http://repository_url/nexus/content/repositories/release/"
  }
  mavenCentral()
}

dependencies {
  compile 'com.google.android.licensing:play-licensing:2.+@aar'
}

android {
  compileSdkVersion 19
  buildToolsVersion '19.1'

  sourceSets {
    main {
      assets.srcDirs       = ['assets']
      res.srcDirs          = ['res']
      aidl.srcDirs         = ['src']
      resources.srcDirs    = ['src']
      renderscript.srcDirs = ['src']
      java.srcDirs         = ['src']
      manifest.srcFile 'AndroidManifest.xml'
    }
  }
}

uploadArchives {
  repositories {
    mavenDeployer {
      repository(url: "http://repository_url/nexus/content/repositories/release/") {
        authentication(userName: "user", password: "password")
      }

      pom.version = "3.0.0"
      pom.artifactId = "play-apk-expansion-downloader"
      pom.groupId = "com.google.android.apk.expansion"
    }
  }
}

并将依赖项更改为 AAR 包：

dependencies {
  compile 'com.google.android.apk.expansion:play-apk-expansion-downloader:3.+@aar'
}

它开始起作用了。
