如何在Android中打开.xlsx文件？

几个月前我写了应用程序。我有Android Kitkat的注2（它没问题）。我的朋友们正在测试（现在他们正在使用它），一切都很好。如何在Android中打开.xlsx文件？

我用Android Nougat（7.0）购买了新手机。现在我无法打开.xlsx文件。单击按钮时使用此方法。

private void ReadXLSX() { 
    nameFILE= "OOOO.xlsx"; 
    Intent target = new Intent(Intent.ACTION_VIEW); 
    target.setDataAndType(Uri.fromFile(new File((getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS))+"/"+ nameFILE)), "application/vnd.ms-excel"); 
    target.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

    Log.v("OPEN_FILE_PATH", getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS) + "/" + nameFILE); 
    startActivity(target);

当我使用debbuger：我在这里，是大跌后

try { 
       mResolvedMethod.invoke(mResolvedContext, v); 
      } catch (IllegalAccessException e) { 
       throw new IllegalStateException(
         "Could not execute non-public method for android:onClick", e); 
      } catch (InvocationTargetException e) { 
       throw new IllegalStateException(
         "Could not execute method for android:onClick", e); 
      }

我的AndroidManifest.xml有：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

使用logcat的检查与碰撞相关的Java堆栈跟踪：https://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-我怎么能解决这个 – CommonsWare

我编辑了我的后添加的LogCat – Dann

你要问对应用程序的权限启动

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE, 1);
