I have two relevant activities: Main and ShowResult. The 2nd one is launched from a Thread in Main. This works well, but as soon as Main is in background the activity won't open. Logcat doesn't show any anomalies.
Manifest:
<activity
android:name="com.....ShowResultActivity"
android:launchMode="singleTop"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen" >
</activity>
<activity
android:name="com......MainActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.Holo.Wallpaper.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Handler inside the Thread-class / executed from Thread:
iOpen = new Intent(context, ShowResultActivity.class); // is written in the constructor
Bundle b = new Bundle(); // global
b.putInt("type", 1);
b.putString("url", value);
iOpen.putExtras(b);
context.startActivity(iOpen);
ShowResult:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onNewIntent(getIntent());
}
#Override
public void onNewIntent(Intent i) {
Bundle b = i.getExtras();
int value = b.getInt("type");
String url = b.getString("url");
Log.e("opened :)", value+" "+url);
if(value == 0) {
showPictureAsync(url);
} else if (value == 1) {
showVideoAsync(url);
}
}
Add this to your code
iOpen.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(iOpen);

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);
}
}
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 followed the following tutorial : http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/
But even after editing android manifest xml as told there I am getting the following error:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.google.zxing.client.android.SCAN pkg=com.google.zxing.client.android (has extras) }
My Code :
public class BarCodeScannerActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button ok;
ok=(Button) findViewById(R.id.b1);
ok.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
// TODO Auto-generated method stub
System.out.println("Helllllllloooooooo");
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE","QR_CODE_MODE");
startActivityForResult(intent, 0);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
System.out.println("onActivityResult________resultCode________ "+resultCode);
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
System.out.println("contentsssssssssssssssssssssss" + contents);
Toast.makeText(getApplicationContext(),"Congratulations!!!... Product Code"+ contents + "On Scanning This Item..." ,Toast.LENGTH_LONG).show();
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
System.out.println("Formaattttttttttttttt " + format);
// Handle successful scan
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
}
}
}
}
And mainfest file:

Hi
Now i am getting a strange problem of attached screen shot once i updated my manifest as follows:
<activity android:name="com.google.zxing.client.android.CaptureActivity"
android:screenOrientation="landscape"
android:configChanges="orientation|keyboardHidden"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter>
<action android:name="com.google.zxing.client.android.SCAN"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
![enter image description here][1]
<activity android:name=".ScanItemActivity"
android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden">
</activity>
I mean it says ""Sorry, the Android camera encountered a problem. You may need to
restart the device."
Nothing is there in logcat.
This is quite confused. You don't need to change your manifest at all if you are integrating by Intent, so remove anything you changed just for the integration.
The app is not installed, and you are not handling this properly. You must catch ActivityNotFoundException, or determine ahead of time that the app to handle the Intent is installed.
But, there is no need for any of this complexity. See http://code.google.com/p/zxing/wiki/ScanningViaIntent . You can use IntentIntegrator, which does all of this for you correctly, in a few lines of code.
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"
android:name=".TalentiFinalActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".KlasaPrikazBaze"></activity>
</application>
