Android应用程序在proguard混淆后崩溃（Google plus people search）

Question

我在我的应用程序中添加了一些代码来搜索Google Plus上的用户。没有Proguard，这个代码运行良好。运行proguard以混淆代码后，我的应用在搜索google plus上的用户时崩溃。

我试图保持的类，在其中都涉及到google.api.sevices.plus ProGuard的配置文件，但这不起作用。

-keep class com.mapegames.sudokukings.** { *; } 
-keep class com.google.api.client.** { *; } 
-keep class com.google.api.services.plus.** { *; } 
-keep class com.google.api.services.plus.model.** { *; } 
-keep class java.lang.** { *; } 
-keep class android.os.** { *; } 

看起来错误发生在下面的代码中的以下执行“src [0] .execute（）”。

import com.google.api.services.plus.Plus; 
import com.google.api.services.plus.model.PeopleFeed; 

private Plus.People.Search searchPeople; 

private void searchPeople(String name) throws IOException { 
    searchPeople = plusSvc.people().search(name); 
    searchPeople.setMaxResults(5L); 
    status.setText(getString(R.string.searching) + " 10%"); 
    Log.i(TAG, "searchPeople: " + searchPeople); 

    new getPeople().execute(searchPeople); 
} 

private class getPeople extends AsyncTask<Plus.People.Search, Void, PeopleFeed> { 

    public PeopleFeed doInBackground(Plus.People.Search... src) { 
     Log.i(TAG, "Start PeopleSearch"); 
     try { 
      Log.i(TAG, "Try PeopleSearch: " + src[0]); 
      return src[0].execute(); 
     } catch (IOException e) { 
      Log.i(TAG, "Catch PeopleSearch"); 
      e.printStackTrace(); 
      return null; 
     } 
    } 

    protected void onPostExecute(PeopleFeed feed) { 
     Log.i(TAG, "Set PeopleSearch"); 
     setPeople(feed); 
    } 
} 

我的日志文件的最后几行显示错误发生在“src [0] .execute（）”。上述

09-13 13:17:14.170: I/PL(2881): searchPeople: {b=yhb, f=5, key=AIzaSyAfaXmYlCopeZuV-Rk5rdwGOBP3Pdkp24o}

林不知道这个信息是足够足够了，所以请让当需要更多的信息我知道。

你可以尝试：

-keep class com.google.api.services.plus.** { *; } 

您还可以检查什么得到通过看the proguard output files.
编辑带走 - 你的问题可能是类似以下：

• http://softwyer.wordpress.com/2012/10/20/android-google-drive-sdk-and-proguard/
• Google Drive API doesn't play well with ProGuard (NPE)

这些适用于Drive，但是NPE的位置相似，并且它们提供了可以从头开始的工作proguard配置。
