Question

根本没有改变我的代码，似乎我的应用程序已经决定它不想再运行了。

每当我尝试在我的模拟器上启动它时，我在日志中收到以下错误：

java.lang.RuntimeException: Performing stop of activity that is not resumed: {...FrontPage}

编辑：这是完整的例外：

我在app工作和不工作之间的间隔期间做的唯一事情就是通过Android Studio下载新的设备模拟器。

FrontPage活动中的完整代码如下：

public class FrontPage extends ActionBarActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.frontpage);
        Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
        toolbar.setTitle("Chess");
        setSupportActionBar(toolbar);



        final ImageButton gamesButton = (ImageButton) findViewById(R.id.goToGames);
        gamesButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View V) {
                Intent i = new Intent(FrontPage.this, chessboard.class);
                startActivity(i);
            }
        });
        final ImageButton rankingsButton = (ImageButton) findViewById(R.id.goToRankings);
        rankingsButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View V) {
                Intent i = new Intent(FrontPage.this, Rankings.class);
                startActivity(i);
            }
        });




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

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;

        }
        return super.onOptionsItemSelected(item);
    }
    }

我没有onResume（）方法，是问题的一部分吗？我不知道如果我的应用程序在整个开发过程中没有它就能正常工作。

在不更改代码
