the problem is when the app run it show the splash screen and then it show the app keep closing,it doesn't start the main activity. can i make the android manifest to make the splash screen show first and then the start main activity

CodePudding user response：

You cannot use your manifest for this, you need to use an Intent.

Code Example that you need in your SplashScreen Activity:

Intent intent = new Intent(SplashScreen.this, YOURNEXTCLASS.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
            finish();

CodePudding user response：

Make Sure Your compileSdkVersion 31 and targetSdkVersion 30.

CodePudding user response：

You can switch activities only from the java files.

Implement this in your OnCreate method.

SplashActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = new Intent(this, MainActivity.class);
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            startActivity(intent);
            finish();
        }
    }, 2000); ////wait 2s before doing the action
}

AndroidManifest.xml

<activity
        android:name=".ui.activities.SplashActivity"
        android:exported="true"
        android:theme="@style/SplashScreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>
<activity
        android:name=".ui.activities.MainActivity"
        android:exported="true"/>
