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 was unable to find out how to show splash screen when starting app from shortcut. Shortcut is a direct path to open certain activity, so splash screen is bypassed. any idea how to include splash screen at every app start combinations ?
My splash implementation:
public class SplashScreen extends AppCompatActivity {
Context context = this;
/** Duration of wait **/
private final int SPLASH_DISPLAY_LENGTH = 2000;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed( new Runnable(){
#Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent goToMainActivity = new Intent(SplashScreen.this, MainActivity.class);
goToMainActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(goToMainActivity);
finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}
Manifest:
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
android:noHistory="true"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.shortcuts" android:resource="#xml/shortcut" />
</activity>
<activity
android:name=".MainActivity"
android:noHistory="true">
</activity>
Shortcut:
<shortcut
android:shortcutId="shortCutEnvironment"
android:enabled="true"
android:icon="#drawable/ic_action_temperature"
android:shortcutShortLabel="#string/shortcut_environment"
android:shortcutLongLabel="#string/shortcut_environment">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.app.myapp"
android:targetClass="com.app.myapp.EnvironmnetScreen"
/>
<category android:name="android.shortcut.conversation"/>
</shortcut>
I have a problem with Main Activity and Splash Screen.There is intent filter both of them
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
When I remove intent-filter from MainActivity the app cannot open.What must I do ?
AndroidManifest.xml
<activity
android:name="com.example.SplashScreen"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#android:style/Theme.Black.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.MainActivity"
android:label="#string/app_name" >
</activity>
SplashScreen Class
public class SplashScreen extends Activity {
private static int SPLASH_TIME_OUT = 3000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
finish();
}
}, SPLASH_TIME_OUT);
}
}
Main Activity Class
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
You need to have intent filter only for your splash screen. And you need to start main activity from your splash screen activity.
Manifest
<activity android:name="com.example.SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.example.MainActivity"></activity>
Start main activity from splash screen and finish it
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
finish();
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);
}
}
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:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.maju.jigsawpuzzle"
android:versionCode="1"
android:versionName="1.0" >

</intent-filter>
</activity>
</application>
</manifest>
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.
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.
