I'm trying to add Splash Screen to my app - java

I have been trying to implement splash Screen to my app with help of many codes avaible in sites , but none worked for me.
Each time the app is crashing after displaying splash screen for 3 secs.
I don't know where i'm going wrong , please make corrections to my code to display splash screen correctly ! Thank You !

AppCompatActivity has it's own toolbar so you need to remove it by using android:theme="#style/AppTheme.NoActionBar" in manifest
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
</activity>
Although if you are not doing much customization in your toolbar then your can also skip creating your own toolbar by removing it from XML and removing it's initialization from java code as well but by doing this , you will lose the feature of collapsing toolbar

Making a splash screen is actually pretty easy.
1. Create drawable
In my case, I created a drawable named splash.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">
<item android:drawable="#color/colorWhite" />
<item>
<bitmap
android:gravity="center"
android:src="#drawable/sensesmart_icon" />
</item>
2. Add drawable to your styles.xml
Here I just added my drawable to styles:
<style name="SplashTheme" parent="AppTheme">
<item name="android:windowBackground">#drawable/splash</item>
</style>
3. Add splash to manifest
You want to actually tell your app that the splash layout should show before the app has loaded:
<activity android:name=".BaseActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme"> <!--Splash screen-->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
4. Set theme on your starting activity
In my case, BaseActivity is the activity which starts my application, so inside my onCreate(), I start with setting my theme:
protected void onCreate(Bundle savedInstanceState) {
setTheme(R.style.AppTheme);
setContentView(R.layout.activity_base);
super.onCreate(savedInstanceState);
}
This is the only thing you need to do. If you use this method, the splash screen doesn't stay for longer than it needs. Your contentView will start as soon as you have loaded your app.
Hope this helps!

Problem with Audio in a basic music player in Android Studio

I created a basic music player app in Android Studio with the music file stored in the raw directory under resources and Mp3 format.
the issue is that though the toast inside the event listener gets displayed , the audio is not playing except once(i really do not know how).
the code is as below.
the manifest file

How do i change activity on a button click android

I have an ImageButton that when I want it to be pressed to launch a second Activity. The second activity is called "Dust 2" as seen in my android manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pete.smokesapp" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".homepage"
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=".Dust2"
android:label="#string/title_activity_dust2" >
</activity>
</application>
</manifest>
I tried following a guide online but got me as far as this stage now my app crashed on launch.
package pete.smokesapp;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
public class homepage extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_homepage);
findViewById(R.id.imgDust2).setOnClickListener((View.OnClickListener) this);
}
public void imgDust2(View view) {
switch (view.getId()){
case R.id.imgDust2:
Toast.makeText(this, "Dust 2 Clicked", Toast.LENGTH_LONG ).show();
break;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_homepage, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
Here is also my main activity, this is the activity with the ImageButton, i am also new to this so sorry if I seem clueless.

There are two methods available in android using which you can go from one Activity to another.
1. Use button.setOnClickListener()
Create a button in xml file.
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
Now set event listener for the button in your .class file
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//set the event you want to perform when button is clicked
//you can go to another activity in your app by creating Intent
Intent intent = new Intent(getApplicationContext, Activity2.class);
startActivity(intent);
}
});
2. Use <android:onClick="goNext">
Put the onClick as the attribute of the button you have created in xml file.
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:onClick="goNext" />
Now in your .class file define an event for that button as,
goNext() {
Intent intent = new Intent(getApplicationContext, Activity2.class);
startActivity(intent);
}

In your first activity do this:
Button button = (Button) findViewById(R.id.imgDust2);
button.setOnClickListener(new View.OnClickListener () {
#Override
public void onClick(View v){
Intent intent = new Intent(v.getContext(), dust2.class);
startActivity(intent);
}
});

Try the following:
Add implements OnClickListener to your class definition: public class homepage extends ActionBarActivity implements OnClickListener
An error will appear and ask you to add unimplemented methods. Do so.
Change findViewById(R.id.imgDust2).setOnClickListener((View.OnClickListener) this); to findViewById(R.id.imgDust2).setOnClickListener(this);
Place the stuff you want to do when the button is clicked into the new method that was added in step 2.

Set onClick to the xml imageView and put the name of the method:
<ImageButton
android:layout_width="350dp"
android:layout_height="150dp"
android:id="#+id/imgDust2"
android:clickable="false"
android:src="#drawable/dust2"
android:layout_above="#+id/imgOverpass"
android:layout_alignLeft="#+id/imgOverpass"
android:layout_alignStart="#+id/imgOverpass"
android:layout_marginBottom="10dp"
android:onClick="imgDust2"/>

Source not found Error and App closes Abruptly

I'm new to Android programming and have been searching this problem for a day now and couldn't come up with a solution. Kindly help me in solving this small problem which is creating a big problem for me.
The error is that when I press the login button in my MainActivity, the app says that unfortunately it has stopped working and the debug window shows an error "Source not found" and further it says ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2249
I've seen similar posts related to this but those posts couldn't help me.
Following my code.

ALSO
I looked over the java code again and found that my code had (button) where in my XML had image button i have change my java code so you can see where i am at the moment..still no luck.I don't know how to copy log cast

From my count, buttonOpenDialog is null so you are getting NPE when you try to add a listener to it. Check your activity_main that you have a Button with an id of im1. You probably misspelled the id or that one simply doesn't exist in your layout. If you don't see a problem with that then post the activity_main.xml.
Also, this isn't your problem but you should consider using Java standard naming conventions. Class names should start with a capital letter. So you would have Main instead of main as your class name.
When you post a question please post the logcat in your question as it always makes it easier for members to read then needing to follow a link that sometimes isn't of the best quality.
