版本6和7中無法打開數據庫

-1

我有數據庫問題。我的應用程序在6版之前無誤地運行。但在運行6或7的Android版本不工作，當stop.my代碼：版本6和7中無法打開數據庫

public class MainActivity extends RuntimePermissionsActivity { 
    private final int WRITE_EXTERNAL_REQUEST_CODE = 30; 
    private final int READ_EXTERNAL_REQUEST_CODE = 80; 

    @Override 
    public void onPermissionsGranted(int requestCode) { 
     if (requestCode == READ_EXTERNAL_REQUEST_CODE) 
      Toast.makeText(getApplicationContext(), "permission", Toast.LENGTH_LONG).show(); 
     else if (requestCode == WRITE_EXTERNAL_REQUEST_CODE) 
      Toast.makeText(getApplicationContext(), " permission", Toast.LENGTH_LONG).show(); 
    } 

    @Override 
    public void onPermissionsDeny(int requestCode) { 
     Toast.makeText(getApplicationContext(), "not permission", Toast.LENGTH_LONG).show(); 
    } 

    public static SQLiteDatabase database; 
    public static final String DIR_SDCARD = Environment.getExternalStorageDirectory().getAbsolutePath(); 
    public static final String DIR_DATABASE = DIR_SDCARD + "/database-shopping";public class MainActivity extends RuntimePermissionsActivity { 
    public static int numPermission=1; 
    private final int WRITE_EXTERNAL_REQUEST_CODE = 30; 
    private final int READ_EXTERNAL_REQUEST_CODE = 80; 

    @Override 
    public void onPermissionsGranted(int requestCode) { 
     if (requestCode == READ_EXTERNAL_REQUEST_CODE) 
      Toast.makeText(getApplicationContext(), "",Toast.LENGTH_LONG).show(); 
     else if (requestCode == WRITE_EXTERNAL_REQUEST_CODE) 
      Toast.makeText(getApplicationContext(), "", Toast.LENGTH_LONG).show(); 
    } 

    @Override 
    public void onPermissionsDeny(int requestCode) { 
     Toast.makeText(getApplicationContext(), "", Toast.LENGTH_LONG).show(); 
    } 

    public static SQLiteDatabase database; 
    public static final String DIR_SDCARD = Environment.getExternalStorageDirectory().getAbsolutePath(); 
    public static final String DIR_DATABASE = DIR_SDCARD + "/database-shopping"; 
@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
      MainActivity.super.requestAppPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE}, WRITE_EXTERNAL_REQUEST_CODE); 
       new File(DIR_DATABASE).mkdirs(); 
       database = SQLiteDatabase.openOrCreateDatabase(DIR_DATABASE + "/shopping.sqlite", null); 
       database.execSQL("CREATE TABLE IF NOT EXISTS person (person_name TEXT NOT NULL ," + 
         "person_email TEXT NOT NULL ," + 
         " person_password TEXT NOT NULL )");

和錯誤顯示，6或7版本上運行：

嗨！如果你在代碼堆棧中創建一個最小，完整和可驗證的例子（http://stackoverflow.com/help/mcve），以便將來可以在Stack溢出時使用，那將會更好。 -謝謝 – Momin

您所要求的權限，那麼不管答案您嘗試打開數據庫，你需要有您的數據庫開放代碼的onPermissionsGranted(int code)方法
