title: java.io.FileNotFoundException when trying to create GoogleCredential
body: <p>I am trying to run this code in my Android App:</p>
  
  <pre><code>    public Bigquery createAuthorizedClient() throws IOException {
      final List SCOPE = Arrays.asList("https://www.googleapis.com/auth/bigquery");
      HttpTransport transport = new NetHttpTransport();
      JsonFactory jsonFactory = new JacksonFactory();
      GoogleCredential credential = new GoogleCredential();
      try{
          File file = new File("C:\\testprojectbigquery\\UkrBikeApp-ff55878cb577.p12");
          credential = new GoogleCredential.Builder().setTransport(transport)
                  .setJsonFactory(jsonFactory)
                  .setServiceAccountId("bigquerymain@ukrbikeapp.iam.gserviceaccount.com")
                  .setServiceAccountScopes(SCOPE)
                  .setServiceAccountPrivateKeyFromP12File(file)
                  .build();
      }
      catch (Exception e){
          System.out.println("e = " + e);
      }
  
  
      if (credential.createScopedRequired()) {
          credential = credential.createScoped(BigqueryScopes.all());
      }
  
      return new Bigquery.Builder(transport, jsonFactory, credential)
              .setApplicationName("Bigquery Samples")
              .build();
  }
  </code></pre>
  
  <p>But every time I get:</p>
  
  <blockquote>
    <p>java.io.FileNotFoundException</p>
  </blockquote>
  
  <p>Then I tried to create InputStream but then didn't change situation:</p>
  
  <pre><code>        AssetManager am = getAssets();
          InputStream inputStream = am.open("C:\\testprojectbigquery\\UkrBikeApp-ff55878cb577.p12");
          File file = createFileFromInputStream(inputStream);
  </code></pre>
