コールにはAPIレベル23が必要です（現在の最小値は22です）。

Question

からの通話要求中に、自分のアプリ内の画像ボタンから直接電話をかけるためのアプリを実行しています。私は、API 22と22の両方でアプリを動作させたいと思っています。しかし、minSDKを22にすると、エラーが発生します。

どのように動作させるには？

agaisntコンパイルしているときには、 runtime permissionを尋ねばなりません

public static final int REQUEST_READ_PERMISSION =111; 
// before on create as global variable 

public void onClick(View v) { 
     switch (v.getId()) { 
      case R.id.imageButton: 
       f (CheckPermission(this, Manifest.permission.CALL_PHONE)) { 
        Intent callIntent = new Intent(Intent.ACTION_CALL); 
        callIntent.setData(Uri.parse("tel:" + 4636)); 
        callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
        startActivity(callIntent); 
       } else { 
       RequestPermission(YourActivityName.this, Manifest.permission.CALL_PHONE, REQUEST_READ_PERMISSION); 
       } 
      break; 
     } 

public boolean CheckPermission(Context context, String Permission) { 
      if (ContextCompat.checkSelfPermission(context, 
        Permission) == PackageManager.PERMISSION_GRANTED) { 
       return true; 
      } else { 
       return false; 
      } 
     } 

public void RequestPermission(Activity thisActivity, String Permission, int Code) { 
      if (ContextCompat.checkSelfPermission(thisActivity, 
        Permission)

       if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
         Permission)) { 
       } else {

          new String[]{Permission}, 
          Code); 
       } 
      } 
     } 

@Override 
     public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) { 

      switch (permsRequestCode) { 

       case REQUEST_READ_PERMISSION: { 
        if (grantResults.length > 0 
          && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
         Intent callIntent = new Intent(Intent.ACTION_CALL);

        } else { 
         ShowToast(getString(R.string.permission_needed_sms)); 
        } 
        return; 
       } 
      } 
     }
