When the splash screen of my Android application opens the application crashes

Question

Initially, the first version of my app worked fine. Later, after changing to the sidebar drawer application template, it does not function properly, crashing the application (due to the splash screen). What could be the issue?

This is the code for the SpashScreen.java file:

public class SplashScreen extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);
    Thread myThread = new Thread(){
        @Override
        public void run(){
            try {
                sleep(3000);
                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                startActivity(intent);
                finish();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };
    myThread.start();
}

}

This is the manifest:

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

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

Answer 1

try this

new Handler().postDelayed(new Runnable() {

        /*
         * Showing splash screen with a timer. This will be useful when you
         * want to show case your app logo / company
         */

        @Override
        public void run() {
            // This method will be executed once the timer is over
            // Start your app main activity
            Intent i = new Intent(SplashScreen.this, MainActivity.class);
            startActivity(i);

            // close this activity
            finish();
        }
    }, 3000);// time in milliseconds

Try this might help

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            Intent intent = new Intent(SplashActivity.this, MainActivity.class);
            startActivity(intent);
            finish();
        }
    }, 3000);

Answer 3

Try to use :

new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            Intent intent = new Intent(SplashScreen.this, MainActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
        }
    }, 3000);

This code don't create new Thread, PS Android cannot start activity from another Thread (only form UI)

Answer 4

startActivity() need to be run in main thread . Using postDelay() of Hanlder class

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