java.lang.RuntimeException : Performing stop of activity that is not resumed in android

Question

我在一个项目上工作了几天并且工作正常。但是今天我在模拟器应用程序中运行我的应用程序，在启动屏幕上暂停而不进入主要 Activity 并且它显示错误:-执行停止不是恢复的 Activity 和ava.lang。 RuntimeException:执行停止未恢复的 Activity

我的 SplashScreen.java:-

public class SplashScreen extends AppCompatActivity {

    private static int SPLASH_TIME_OUT = 3000;
    Boolean flag = false;
    public static Activity activity_splash;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.splash_screen);

    }
    public void onResume(){
        super.onResume();
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent i = new Intent(SplashScreen.this, MainActivity.class);
                startActivity(i);
                finish();
            }
        }, SPLASH_TIME_OUT);
    }

}

Answer 1

在 MainActivity 的 onCreate 中，如果可以访问互联网，您将调用 displayView(0);。在 displayView 中，

case 0:
     Intent intentHome = new Intent(MainActivity.this,MainActivity.class);
     startActivity(intentHome);
     break;

在这里，您再次启动 MainActivity，因此应用程序陷入了无限循环。最终它崩溃了。
