Question

I have a small app, then when I get out of the app (minimizo) and open again, it starts with the application of the home screen instead of opening the page you left off. That is, it starts the application all over again when it is minimized.

 <?xml version="1.0" encoding="utf-8"?>
    package="com.example.kevin.estudosbiblicos" >

<uses-permission android:name="android.permission.INTERNET"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/icon"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <activity android:name=".MainActivity"

        android:configChanges="orientation|keyboardHidden"
        android:label="@string/app_name">

    </activity>

    <activity android:name=".Splash">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

Answer 1

首先，您需要在启动mainActivity后完成启动活动。

new Timer().schedule(new TimerTask() {


    public void run() {

        Intent intent = new Intent();
        intent.setClass(Splash.this, MainActivity.class); //Chamando a classe splash e a principal (main)
        startActivity(intent);

        finish();

         }
}, 2000);

在mainActivity中，你可以在onpause方法中调用finish（）方法吗？请显示整个mainActivity代码

并且您不应在活动中使用完成暂停。

我的主要活动：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        getSupportActionBar().hide();

        // CODIGO DO WEB VIEW

        final WebView myWebView = (WebView) findViewById(R.id.webView);
        myWebView.loadUrl("http://www.idestudos.com.br");
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setSupportZoom(true);
        webSettings.setBuiltInZoomControls(true);

        myWebView.setWebViewClient(new MyBrowser());

        myWebView.setWebViewClient(new WebViewClient() { //CODE WEBVIEW }

MY CLASS SPLASH：

public class Splash extends Activity{

private static int tempo_splash = 1000;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Para o layout preencher toda tela do cel (remover a barra de tit.)

    new Timer().schedule(new TimerTask() {


        public void run() {
            finish();

            Intent intent = new Intent();
            intent.setClass(Splash.this, MainActivity.class); //Chamando a classe splash e a principal (main)
            startActivity(intent);
        }
    }, 2000);


}

}

Answer 3

<activity ...
  android:alwaysRetainTaskState="true"/>

对要保存状态的所有活动执行此操作。

When I minimize the app that created, Why it starts all over again when opening?
