我真的很新到Android编程,因此,如果协助我时,那将是极大的AP preciated可以是具体的。
公共类SplashScreenActivity延伸活动{

@覆盖 公共无效的onCreate(捆绑savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.main);
定时器定时器=新的Timer();
timer.schedule(新MyTask(),5000);

类MyTask扩展的TimerTask { @覆盖
公共无效的run(){
意向意图=新意图(SplashScreenActivity.this,SecondActivity.class);

startActivity(意向);

When i try to run my app, the splash screen comes up correctly, and right after it closes, a message pops up that says "Unfortunatly, First app has stopped working" I've tried a ton of different solutions I've found but i believe in my case, it's a problem with my code after testing a new "Hello World" app within the emulator. Here's a copy of my androidmanifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.examle.firstapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".Splash" android:label="@string/app_name" >
<intent-filter>
<action android:name="com.example.firstapp.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity" android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAINACTIVTY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
Here is what comes up in log cat after trying some of the solutions

I'm really quite new to android programming, so if you could be specific when assisting me it would be greatly appreciated.
public class SplashScreenActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Timer timer=new Timer();
timer.schedule(new MyTask(), 5000);
}
class MyTask extends TimerTask{
@Override
public void run() {
Intent intent=new Intent(SplashScreenActivity.this,SecondActivity.class);
finish();
startActivity(intent);
}
}
}
