Question

我在我的应用中添加了一些代码来搜索Google Plus上的人。这段代码在没有Proguard的情况下运行良好。在运行proguard来混淆代码后，我的应用程序在搜索google plus上的人时崩溃。

我试图将这些类保存在与google.api.sevices.plus相关的proguard配置文件中，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.** { *; }

以下代码中的执行“src [0] .execute（）”似乎发生错误。

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);
     }
 }

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

我不确定上述信息是否足够，所以如果需要其他信息，请告诉我。

你可以尝试：

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

您还可以通过查看the proguard output files.来查看被删除的内容编辑 - 您的问题可能类似于：
