Androidで.xlsxファイルを開く方法は？

Question

私は数ヶ月前にアプリを書いた。私はAndroid Kitkatでノート2を持っていた（それは大丈夫だった）。私の友人はテストしていました（そして今、彼らはそれを使用しています）、そしてすべては大丈夫です。

Android Nougat（7.0）で新しい携帯電話を購入しました。 今すぐ.xlsxファイルを開くことができません。 ボタンをクリックすると、このメソッドが使用されます。

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); 

私がdebbuger使用する場合： を私はここに、そのクラッシュ後

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); 
      } 

私のAndroidManifest.xmlがあります

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

あなたはアプリケーションの権限が

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