I am getting error "Implicit intents with startService are not safe"

I am deploying a vpn app.Which can connect to my vpn service which is duck vpn.It a simple app.But i am not able to connect to vpn service due to Implicit intents error.

This is my vpn connect function

private void connect(final VpnProfile profile, final String username, final String password) {

    mVpnManager.startVpnService();


    ServiceConnection c = new ServiceConnection() {
        public void onServiceConnected(ComponentName className,
                IBinder service) {
            try {

                boolean success = IVpnService.Stub.asInterface(service)
                        .connect(profile, username, password);
                if (!success) {
                    Log.d(TAG, "~~~~~~ connect() failed!");
                } else {
                    Log.d(TAG, "~~~~~~ connect() succeeded!");
                }
            } catch (Throwable e) {
                Log.e(TAG, "connect()", e);
                broadcastConnectivity(VpnState.IDLE,
                        VpnManager.VPN_ERROR_CONNECTION_FAILED);
            } finally {
                MainActivity.this.unbindService(this);
            }
        }

        public void onServiceDisconnected(ComponentName className) {
            checkStatus();
        }
    };
    if (!bindService(c)) {
        broadcastConnectivity(VpnState.IDLE,
                VpnManager.VPN_ERROR_CONNECTION_FAILED);
    }

}

At this line

ServiceConnection c = new ServiceConnection() 

My log cat shows this

And moves to this catch block

catch (Throwable e) {
                Log.e(TAG, "connect()", e);
                broadcastConnectivity(VpnState.IDLE,
                        VpnManager.VPN_ERROR_CONNECTION_FAILED);
            } 

And i am not able to create vpn connection due to implicit intent error.How to solve this intent issue?Thanks in advance :)
