I am creating a Jigsaw Puzzle application in android. I have created two activites, activity_jigsaw.xml and activity_level.xml. One activity is created by default (Displaying Hello World!) which I modified and created a new activity by following these steps:
File -> New -> Other -> Android Activity
But when I install the application these two files (and all other activities of the application) are installed as a separate project. But at the same time they are also interlinked. The Java code of the files as follows:
Jisaw.java file contains:
public class Jigsaw extends Activity {
Intent intent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_jigsaw);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_jigsaw, menu);
return true;
}
public void play(View v)
{
try
{
intent = new Intent(this, Level.class);
startActivity(intent);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
Here Play is a function which is called when an image is clicked.
Level.java file contains:
public class Level extends Activity {
Intent intent;
String level = "";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_level, menu);
return true;
}
public void easy(View v)
{
level = "easy";
intent = new Intent(this, Play.class);
intent.putExtra("level", level);
startActivity(intent);
}
public void medium(View v)
{
level = "medium";
intent = new Intent(this, Play.class);
intent.putExtra("level", level);
startActivity(intent);
}
public void hard(View v)
{
level = "hard";
intent = new Intent(this, Play.class);
intent.putExtra("level", level);
startActivity(intent);
}
}
Functions easy, medium and hard are called when a corresponding image is clicked.
Can somebody please tell me that what I am doing wrong?
Thanks in advance..
Here is the manifest file:

You probably are defining android.intent.category.LAUNCHER intent category to all the activities in your AndroidManifest.xml, it creates an icon in the app launcher. Activities other than main should not have this intent filter.
Do something like this:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity android:name=".JigSaw" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Level" />
<activity android:name=".Play" />
<activity android:name=".Playboard" />
</application>
EDIT:
As you just posted, you are indeed doing that, just remove the intent filter from other activities.

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>
I have created a splash activity for my app. I am trying to redirect from my Splash activity to the Starting Point activity using AndroidManifest.xml but its not working. The Splash class loads up, and then it doesn't redirect to the Starting Point. And it doesn't give any errors either.
So can you please help me figure it out.

<action android:name="com.example.myapp.STARTINGPOINT" />

</intent-filter>
</activity>
</application>
</manifest>
Now I have also tried
<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=".StartingPoint"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.example.myapp.STARTINGPOINT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
So what can I do here. I am not getting redirected from Splash to my Starting Point.
Splash Code
package com.example.myapp;
import android.app.Activity;
import android.os.Bundle;
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
}
}
Add this code to your Splash.java
Thread timer = new Thread(){
public void run(){
try {
sleep(2000);
} catch (Exception e) {
// TODO: handle exception
} finally{
Intent i = new Intent(Flash_Activity.this, StartingPoint.class);
startActivity(i);
}
}
};
timer.start();
}
You are never calling anything to change the activity from your splash to the starting point. This thread will do that.
Use this easy way to redirect to acitvity
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(this,MainActivity.class);
startActivity(intent);
finish();
}
},2500);
I was trying to get a small image to show up before my Main Activity starts. This is my current coding in the android manifest
<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.example.test.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
whatever I do, my splash screen does not start. They start separately, but never together, (I still haven't put a timer in my splash image as I want to check whether it works or not and it isn't working)
Remove
<intent-filter>
<action android:name="com.example.test.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Use below code in splash screen after desired time
Intent intent=new Intent(this,MAINACTIVITY.class);
startActivity(intent);
finish(); //To close splashscreen when MAINACTIVITY loads
The above code starts with splash screen and after some time start your main activity
You should remove the <intent-filter> section from your MainActivity declaration ,
and launch the MainActivity from the splashActivity using a simple intent and startActivity call.
Try this.
<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" >
</activity>
</application>
Code for your Splash Class-
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
public class Splash extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{ // TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
final Handler handle = new Handler();
Runnable delay = new Runnable() {
public void run() {
startActivity(new Intent(Splash.this, MainActivity.class));
finish();
}
};
handle.postDelayed(delay,5000);
}
}
its delay next intent 5 second. you can set time according to you.
Use This:
<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" >
</activity>
</application>
and This :
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
Intent mInHome = new Intent(Splash.this, MainActivity.class);
Splash.this.startActivity(mInHome);
Splash.this.finish();
}
}, 3000);
}
}
Im very new to android development so please bear my ignorance.
I created a Splash screen before loading my main activity. Splash is working fine but what causes the problem is the main activity, it keeps on instantiating.
Splash.java
public class Splash extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
final AdController optinController = new AdController(
getApplicationContext(), "SECTION_ID");
final Splash splash = this;
optinController.loadOptin((Activity) splash, "SECTION_ID",
new AdOptinListener() {
public void onAdOptin() {
// once optin process is complete, continue to main app activity
launchMain();
}
}
);
}
public void launchMain() {
finish();
Intent myIntent = new Intent(Splash.this, MainActivity.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(myIntent);
}
}
MainActivity.java
public class MainActivity extends Activity {
private AdController myController;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myController = new AdController(getApplicationContext(), "SECTION_ID");
myController.loadNotification();
}
}
In the manifest file:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/title_activity_splash" >
<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/title_activity_main"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I used android:launchMode="singleInstance" but still it keeps on reinstantiating.
Please help. Thanks in advance.
public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//|Window.FEATURE_INDETERMINATE_PROGRESS
setContentView(R.layout.splash);
final Timer time = new Timer();
time.schedule(new TimerTask() {
#Override
public void run() {
Intent intent = new Intent(Splash.this,MainActivity.class);
startActivity(intent);
finish();
}
},1000);
}}
It will work , i din get you exactly by instatiating.Also do no use single instance,you are not supposed to require it here.
Yes, following is my snippet of manifest file , just use a timer for your splash screen and move to your main class after specific time.
activity android:name=".Splash"
android:screenOrientation="portrait" android:label="#string/app_name">
i think you have to remove the intent flag Intent.FLAG_ACTIVITY_SINGLE_TOP
In manifest.xml, set category as LAUNCHER which activity you want to launch first and to Other set as DEFAULT as given in below example.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/title_activity_splash" >
<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/title_activity_main"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
I have 2 activities with a few buttons etc. I want to start new activity. I have done everything the tutorial said, but the 2nd activity does not start!
case R.id.btnIstorija:
Intent i = new Intent (this,KlasaPrikazBaze.class);
startActivity(i);
break;
It should start my 2nd activity
public class KlasaPrikazBaze extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.prikazbaze);
TextView TV = (TextView)findViewById(R.id.tvSQLinfo);
KlasaBaze info = new KlasaBaze(this);
info.open();
String podatak = info.DohvatiPodatak();
info.close();
}
}
However nothing happens.
Manifest:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:label="#string/app_name"
