Androidのアクセス許可6.0以上

Question

私は自分自身のクラスを作成して、Marshmallowに対する要求の許可を確認しようとしていますが、通常の危険なアクセス許可があることを知っています。アプリの非常に基本的な機能は着信をブロックすることです。

public class RequestPermission { 

    private String[] modifyPhoneStatePermission = {Manifest.permission.MODIFY_PHONE_STATE}; 
    private String[] contactsPermission = {Manifest.permission.READ_CONTACTS}; 
    private String[] phonePermissions = {Manifest.permission.CALL_PHONE, Manifest.permission.READ_PHONE_STATE}; 


    private Context context; 

    public RequestPermission(Context context) 
    { 
     this.context = context; 
    } 

public boolean checkModifyPhoneStatePermission() { 
    try 
    { 
     if (ContextCompat.checkSelfPermission(context, modifyPhoneStatePermission[0]) == PackageManager.PERMISSION_GRANTED) { 

      return true; 

     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    return false; 
} 

    public void askModifyPhoneStatePermission() { 
    try 
    { 
     ActivityCompat.requestPermissions((Activity) context, modifyPhoneStatePermission, REQUEST_CODE_PERMISSION); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

} 

ただし、これを別のクラスで試すと、ダイアログボックスが表示されません。なぜこうなった？ phonePermissions配列にこれを含める必要がありますか？ブロックしている通話にMODIFY_PHONE_STATEが参加していますか？コードの下

チェックアウト：コードの下

 private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 10001; 

        @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 

       if (platform_version >= 23) { 
        boolean permission = checkAndRequestPermissions(); 
        /*if (permission) 
         Toast.makeText(this, "All permissions granted!", Toast.LENGTH_LONG).show();*/ 
       } 

     } 







     private boolean checkAndRequestPermissions() { 
      int modifyPhoneStatePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.MODIFY_PHONE_STATE); 
      int contactsPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS); 
      int phonePermissions = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE); 
      int permissionReadExternal = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE); 

      List<String> listPermissionsNeeded = new ArrayList<>(); 
      if (modifyPhoneStatePermission != PackageManager.PERMISSION_GRANTED) { 
       listPermissionsNeeded.add(Manifest.permission.MODIFY_PHONE_STATE); 
      } 
      if (contactsPermission != PackageManager.PERMISSION_GRANTED) { 
       listPermissionsNeeded.add(Manifest.permission.READ_CONTACTS); 
      } 
      if (phonePermissions != PackageManager.PERMISSION_GRANTED) { 
       listPermissionsNeeded.add(Manifest.permission.READ_PHONE_STATE); 
      } 
if (!listPermissionsNeeded.isEmpty()) { 
      ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS); 
      return false; 
     } 

      return true; 
     } 





      @Override 
     public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) { 
      Log.d(PERMISSION_TAG, "Permission callback called..."); 
      switch (requestCode) { 
       case REQUEST_ID_MULTIPLE_PERMISSIONS: { 

        Map<String, Integer> perms = new HashMap<>(); 
        // Initialize the map with both permissions 

        perms.put(Manifest.permission.MODIFY_PHONE_STATE, PackageManager.PERMISSION_GRANTED); 
        perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED); 
        perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED); 

        // Fill with actual results from user 
        if (grantResults.length > 0) { 
         for (int i = 0; i < permissions.length; i++) 
          perms.put(permissions[i], grantResults[i]); 
         // Check for both permissions 
         if (perms.get(Manifest.permission.ACCESS_NETWORK_STATE) == PackageManager.PERMISSION_GRANTED && 
           perms.get(Manifest.permission.ACCESS_WIFI_STATE) == PackageManager.PERMISSION_GRANTED && 
           perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED && 
           perms.get(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) { 
          Log.d(PERMISSION_TAG, "permission granted"); 
          // process the normal flow 
          //else any one or both the permissions are not granted 
         } else { 
          Log.d(PERMISSION_TAG, "Some permissions are not granted ask again "); 
          //permission is denied (this is the first time, when "never ask again" is not checked) so ask again explaining the usage of permission 
    //      //shouldShowRequestPermissionRationale will return true 
          //show the dialog or snackbar saying its necessary and try again otherwise proceed with setup. 
          if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_NETWORK_STATE) && ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) { 
           showDialogOK("Permission required for this app", 
             new DialogInterface.OnClickListener() { 
              @Override 
              public void onClick(DialogInterface dialog, int which) { 
               switch (which) { 
                case DialogInterface.BUTTON_POSITIVE: 
                 checkAndRequestPermissions(); 
                 break; 
                case DialogInterface.BUTTON_NEGATIVE: 
                 // proceed with logic by disabling the related features or quit the app. 
                 checkAndRequestPermissions(); 
                 break; 
               } 
              } 
             }); 
          } 
          //permission is denied (and never ask again is checked) 
          //shouldShowRequestPermissionRationale will return false 
          else { 
           //proceed with logic by disabling the related features or quit the app. 

          } 
         } 
        } 
       } 
      } 
     } 

はあなたのケースで動作しますが、あなたが望む任意の方法で、以下のチェックを使用するか、onCreate()

if (platform_version >= 23) { 
       boolean permission = checkAndRequestPermissions(); 
       /*if (permission) 
        Toast.makeText(this, "All permissions granted!", Toast.LENGTH_LONG).show();*/ 
      }
