How to start another activity after a splash screen in android studio

Question

Hi everyone I'm studying now and developing a app in android studio. My problem is i can't proceed to my log in activity after splash screen. I already look in the net and stackoverflow and applied it, but still same error. I appreciate for the help and answer.

Here are some of my code

SplashScreen.java

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            final Intent mainIntent =  new Intent(SplashScreen.this, Login.class);
            SplashScreen.this.startActivity(mainIntent);
            SplashScreen.this.finish();
        }
    },3000);

}

Login.java

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.login);

    Intent intent = new Intent(Login.this, MainActivity.class);
    startActivity(intent);
    finish();
  }

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/logo"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".SplashScreen"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity
        android:name=".Login"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".Login"/>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="com.ex.app.MainActivity" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

where did i go wrong ?

Answer 1

As you have written code to move to MainActivity on the method onCreate of Login.java

Intent intent = new Intent(Login.this, MainActivity.class);
startActivity(intent);
finish();

Comment this line or keep it on the click of SignIn button

Answer 2

Your login activity just directs you to the MainActivity on create

Look at these lines

Intent intent = new Intent(Login.this, MainActivity.class);
startActivity(intent);

Answer 3

It is redirecting to MainActivity directly as in your LoginActivity onCreate you have written

Intent intent = new Intent(Login.this, MainActivity.class);
startActivity(intent);
finish();

without any condition. Make it conditional by putting your login check conditions and criteria

if (<logged_in_your_condition_Check>){
    Intent intent = new Intent(Login.this, MainActivity.class);
    startActivity(intent);
    finish();
}

Answer 4

why you require below lines in Login.class

 Intent intent = new Intent(Login.this, MainActivity.class);
    startActivity(intent);
    finish();

if you are using finish() in onCreate() then it will immediately called onDestroy() and that dosen't make any sense.

remove above given code from onCreate your code will work

Answer 5

in manifest write:

<activity
android:name=".MySplashActivity"
android:noHistory="true"
 ..... >
    ....
</activity>

then in create() or somewhere different cal the method:

 private static int SPLASH_TIME_OUT=2000;

 
private void nextScreen() {
    new Handler().postDelayed(()-> {
            Intent intent = new Intent(MySplashaActivity.this, NextActivity.class);
            startActivity(intent);
            finish();
    }, SPLASH_TIME_OUT);
}
