title: try-with-resources are not supported at this language level - Android
body: <p>I have a problem with "try-with-resources are not supported at this language level" in android in the following posted code, I tried to set language to 7 but it stills keeps giving me the same example plus it keeps giving me the option to change to language 7.</p>
  
  <pre><code>public String ReadFile(String fileName) {
  
      try (BufferedReader br = new BufferedReader(new FileReader(fileName+".txt"))) {
          StringBuilder sb = new StringBuilder();
          String line = br.readLine();
  
          while (line != null) {
              sb.append(line);
              sb.append(System.lineSeparator());
              line = br.readLine();
          }
  
          String everything = sb.toString();
          return everything;
      } catch (FileNotFoundException ex) {
          Logger.getLogger(SaveNLoadRank.class.getName()).log(Level.SEVERE, null, ex);
      } catch (IOException ex) {
          Logger.getLogger(SaveNLoadRank.class.getName()).log(Level.SEVERE, null, ex);
      }
      return "1";
  }
  </code></pre>
