animated splash screen doesn't appear

In this project I tried to make an animated splash screen which will appear before going to the main activity, but after I execute, the splash screen does not appear but instead goes directly to the main activity.
how to fix this?
this is my splash activity class
private ImageView container;
private AnimationDrawable animationDrawable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash)
container = findViewById(R.id.iv_icons);
container.setBackgroundResource(R.drawable.mysplash_animation);
animationDrawable = (AnimationDrawable) container.getBackground();
}
#Override
protected void onResume() {
super.onResume();
animationDrawable.start();
checkAnimationStatus(50, animationDrawable);
}
private void checkAnimationStatus(final int time, final AnimationDrawable animationDrawable) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
if (animationDrawable.getCurrent() != animationDrawable.getFrame(animationDrawable.getNumberOfFrames() - 1))
checkAnimationStatus(time, animationDrawable);
else finish();
}
}, time);
}
}
and this is my manifest.xml
<application
android:allowBackup="true"
android:exported="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.AppCompat.NoActionBar">
<activity android:name=".SplashActivity"></activity>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

You have to change this in your manifest(you have to give launcher activity to splashActivity)
<application
android:allowBackup="true"
android:exported="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.AppCompat.NoActionBar">
<activity android:name=".SplashActivity">
// below code you have to add //
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity">
//Remove from here//
</activity>
</application>

Set your Splash Activity as the Launcher activity:
<activity android:name=".MainActivity"></activity>
<activity android:name=".SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

Please provide intentfilter to SplashActivity
<application
android:allowBackup="true"
android:exported="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.AppCompat.NoActionBar">
<activity android:name=".SplashActivity">
<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>

ActivityNotFoundExceptionstarted appearing out of nowhere

Before my application was working fine. I just created a new class (within the same package) and also declared it in the manifest, still I get a ActivityNotFoundException and sometimes NoClassDefFoundException.
TestActivity.java
public class TestActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.order_summary);
}
}
Activity_NewOrder.java
public class Activity_NewOrder extends Activity
try {
//Also tried Intent intent = new Intent(Activity_NewOrder.this, TestActivity.class);
Intent intent = new Intent(getApplicationContext(), TestActivity.class);
startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Cant't figure out what is wrong.please help to solve this issue
And one more question
In android mainfest the name action name can be anything or it has to be path from package like "com.GTC.classname"

you have two application tags in your manifest. change it to one with both activities

please modify your manifest like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gtctest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="14" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".StartingPointActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.GTC.STARTINGPOINTACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
ps: in android mainfest, the action name can be anything, but we used to make it like "com.xxx.intent.action.XXX".

Try this way,hope this will help you to solve your problem.

}

}

Create Intent Like Following...
Intent intentname =new Intent(SplashScreen.this,StartingPointActivity.class);
startActivity(intentname);
Change in your AndroidManifest.xml File..
You have defined two <application> tag....
remove that and change it to following..
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gtctest"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="14" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- add new activities like this -->
<activity
android:name=".StartingPointActivity"
android:label="#string/app_name" >
<!-- if your activity in different package you can define like this... (xx.xxx is your package name define your package name there..)
<activity
android:name="xx.xxx.StartingPointActivity"
android:label="#string/app_name" >
-->
</application>
</manifest>

Unable to find explicit activity class error

</intent-filter>
</activity>
<!-- Entry for RegisterActivity.class -->
<activity android:name=".RegisterActivity"
android:label="Register New Account"></activity>
</application>
Don't know why this error is appearing and application crashes. please help guys.can there be any problem anywhere else
here is my class file
public class MainActivity extends ActionBarActivity {
Button login_b1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
TextView registerScreen = (TextView) findViewById(R.id.link_to_register);
// Listening to register new account link
registerScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Switching to Register screen
Intent i = new Intent(getApplicationContext(), RegisterActivity.class);
startActivity(i);
}
});
}
}

Place this code below the register Activity. I guess that should be the error
<intent-filter>
<action android:name="android.intent.action.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Android app force closing after splash screen

I have a splash screen with a timer that runs for 3 seconds. After the 3 seconds it is supposed to auto load another activity called Dashboard. I made a new class that I want to have load after the splash screen called WelcomeSplash. I changed the classes in the splash screen from Dashboard to WelcomeSplash and the app force closes and the logcat says it has a null point exception. Here is the snip of code from the splash class and logcat snip.
02-13 23:18:46.826: E/AndroidRuntime(2475): FATAL EXCEPTION: main
02-13 23:18:46.826: E/AndroidRuntime(2475): java.lang.RuntimeException: Unable to start

02-13 23:18:46.826: E/AndroidRuntime(2475): at
android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059)
Here is the snip of the Splash code
startActivity(new Intent(Splash.this, welcomeSplash.class));
When I change the welcomeSPlash.class to Dashboard.class the app does not force close. Here is the welcomeSplash Activity,
public class welcomeSplash extends Activity implements OnClickListener {
Button btnskip;
Button btnplay;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome);
btnskip =(Button) findViewById(R.id.btnSkip);
btnskip.setOnClickListener(this);
btnplay =(Button) findViewById(R.id.btnOk);
btnplay.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSkip:
Intent a = new Intent(welcomeSplash.this, Dashboard.class);
startActivity(a);
break;
case R.id.btnOk:
Intent i = new Intent(welcomeSplash.this, Profile.class);
startActivity(i);
break;
}
}
}
THe manifest is copied below too.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
