The process is forced to terminate when the Android toolbar is applied.

public class ServiceActivity extends AppCompatActivity {

    private Toolbar mToolbar;
    String ClientTAG = "Client";
    String OptionTAG = "Option";
    private Context context = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_service);
        mToolbar = (Toolbar) findViewById(R.id.toolBar);
        mToolbar.setTitle("tool test");
        mToolbar.setTitleTextColor(Color.WHITE);

        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowHomeEnabled(true);

    }

    public boolean onCreateOptionsMenu(Menu menu) {
        // // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }
