already performed clean project, rebuild project, analysed and inspected code but it does not resolve the issue. This started when making "Slash Screen" i check my XML files it looks good to me, but started to realize in every .Java class i created symbol R. was underlined with red try everything i can think of....
`package com.example.dom.myapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Splashscreen extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread() {
public void run() {
try
{
sleep(4000);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
Intent myactivity = new Intent("com.example.dom.MAINACTIVITY");
startActivity(myactivity);
}
}
};
timer.start();
}
}`
Here's my Splash layout
<?xml version="1.0" encoding="utf-8"?>

In splash layout do this
android:background="#+id/drawable/front" must be android:background="#drawable/front" remove this #+id/
looks like this:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

I am new to android development, and I'm trying to add a splash screen in my app.
I found this tutorial:
I have added the files as mentioned in the tutorial but it doesn't seems to work, there is an error in my Splashscreen.java file
It gives me the error cannot resolve symbol androidmkab
Thanks for helping in advance.

import com.androidmkab.randomsplash.MainActivity; remove this line from the top. Its not your package... instead make it import com.myapplication.MainActivity
the problem seems to be that you are trying to call a package which does not exist in your project. androidmkab.randomsplash.MainActivity should be replaced with your project package. such as com.myApplication.MainActivity
Delete the line com.androidmkab.randomsplash.MainActivity; and write com.myapplication.MainActivity;
i am trying to get a sound file to play when my splash screen is showing on my android app.... i have been trying to figure it out for a few hours now..... when i run my app it just skips the splash sreen all together now

Did you declare your activity in the manifest?
If you did, this question was asked before, try the following:
Android Sound not playing in splash screen
How to play audio in splash screen in android
You can try this
MediaPlayer player = new MediaPlayer();
player.setDataSource("/sdcard/audiotrack.mp3");
player.prepare();
player.start();
I'm trying to start an activity
`package com.kapzlock.mytestproject;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Splash extends Activity{
#Override
protected void onCreate(Bundle SomeVar) {
// TODO Auto-generated method stub
super.onCreate(SomeVar);
setContentView(R.layout.splash);
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
}
catch(InterruptedException e){
e.printStackTrace();
}
finally{
Intent openStartingPoint = new Intent("com.kapzlock.mytestproject.MAINACTIVITY");
startActivity(openStartingPoint);
}
}
};
timer.start();
}
/**
* #param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
`
The Manifest xml file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kapzlock.mytestproject"
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="android.intent.action.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="com.kapzlock.mytestproject.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
It compiles without problems, but when I run the Splash.class, I'm getting an Exception in thread "main" java.lang.NoClassDefFoundError: android/app/Activity Error. The package name is com.kapzlock.mytestproject and the class that I'm referencing to is MainActivity.class. Has anybody an idea where the mistake could be in?
Try this:
Go to Project/Properties/Java Build Path/Order and Export -- Make sure there's a check in front of Android Dependencies and the support library, if you use it.Mark all checkboxes.Click on Apply and clean the project.
This worked for me.Hope this helps.
Replace your code with following
finally
{
Intent openStartingPoint = new Intent(this,MAINACTIVITY.class);
startActivity(openStartingPoint);
}
Remove following from your manifest.xml in mainActivity tag
<intent-filter>
<action android:name="com.kapzlock.mytestproject.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

I think it something wrong with the manifest but I can't really see what's wrong, any ideas? Plus the video are in mp4 so they're are in the right format for android
I think, you just missed one little thing: a dot (.)
See at your code here:
Class ourclass = Class.forName("com.example.taekwondobuddy.util" + cheese);
don't you think it should be like this:
Class ourclass = Class.forName("com.example.taekwondobuddy.util." + cheese);
Try to use:
mVideoView.start();
So I'm building my very first android app. Trying to get my splash screen to work. But Splash.java is showing an error " StartingPoint cannot be resolved to a type.

}
}
Hope you guys can help me out
try this one:
<?xml version="1.0" encoding="utf-8"?>

</activity>
</application>
</manifest>
EDIT: note that put MainActivity as your starting point, that is first activity after splash screen
hope it helps
In your manifest defining StartingPoint you have the category defined as android.intent.category.DEDAULT, should be android.intent.category.DEFAULT.
