Android Start Splash activity or app without having any intent-filters in its manifest?

As We Know Starting Activity declare in manifest.xml
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
But this way is some how in secure
is there any other way to start launching activity or app with out declaring any intent-filter manifest.xml

is having two broadcast receivers valid in android?

i don't know if this is okay having two broadcast receivers in my android app. I separated them cause the one receiver with the boot_completed, it will do a different task and the other receiver with also do different task when they receive a broadcast.
<receiver android:name=".Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<receiver
android:name=".AlarmManagerBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>

That is perfectly valid you should always try to seperate your concerns which part of a good architecture/good design principles.

android receiver stops after clean ram

I have a gcm receiver, but it is not working before restarting phone and after clean memory. What should i change to guarantee receiver is always working?
<activity
android:name="com.example.diyet.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.plugin.gcm.PushHandlerActivity"/>
<receiver android:name="com.plugin.gcm.CordovaGCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.plugin.gcm" />
</intent-filter>
</receiver>
<service android:name="com.plugin.gcm.GCMIntentService" />,
thanks in advance

if u want to start your receiver manually then use
registerReceiver(receiver) inside your activity

Sorry I don't know anything about GCM but if I get you right you have one of the following possibilities
If your GCMIntentService is custom, you can make this Service STICKY So the OS restarts it after a Crash. To do this you have to return return Service.START_STICKY; in your onStartCommand Method.
Also you can Register for the android.intent.action.BOOT_COMPLETED to get your Service started right after device is Booted.
If you want to prevent the Service to Crash, when the App Crashes you have to put it in another Thread. This can be achieved by Setting an custom Process Name in the Manifest
android:process="com.gigatronik.presenter.serialport.SerialPortListenerService"/
I will edit this answer, if you can give me more information on your Problem, since I never used GCM

Android: Start Service on boot?

I'm reaaaaally new to Java, but an experienced C#-coder.
I've created a service which I can start/stop from an activity.
My question is, how do I "install" this service so it does start upon boot of my device?
I found this:
Trying to start a service on boot on Android
I've tried to implemented this like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="james.jamesspackage" android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:icon="#drawable/icon" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".jamessActivity" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true" android:name=".MyService">
<intent-filter>
<action android:name="james.jamesspackage.MyService" />
</intent-filter>
</service>
<receiver android:name="james.jamesspackage.MyBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
</application>
</manifest>
What's wrong? Can I have an activity and a service/receiver in one manifest?
Thanks

How to start service on device boot(autorun app, etc.)
For first: since version Android 3.1+ you don't recieve BOOT_COMPLETE if user never started yor app at least once or user "force closed" application.
This was done to prevent malware automaticaly register service. This security hole was closed in newer versions of Android.
Solution:
Create app with activity. When user run it once app can recieve BOOT_COMPLETE broadcast message.
For second: BOOT_COMPLETE is sent before external storage is mounted. if app is installed to external storage it won't receive BOOT_COMPLETE broadcast message.
In this case there is two solution:
Install your app to internal storage
Instal another small app in internal storage. This app recieves BOOT_COMPLETE and run second app on external storage.
If your app already installed in internal storage then code below can help you understand how to start service on device boot.
In Manifest.xml
Permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Register your BOOT_COMPLETED reciever:
<receiver android:name="org.yourapp.OnBoot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
Register your service:
<service android:name="org.yourapp.YourCoolService" />
In reciever OnBoot.java:
public class OnBoot extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
// Create Intent
Intent serviceIntent = new Intent(context, YourCoolService.class);
// Start service
context.startService(serviceIntent);
}
}
For HTC you maybe need also add in Manifest this code if device don't catch RECEIVE_BOOT_COMPLETED:
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
Reciever now look like this:
<receiver android:name="org.yourapp.OnBoot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
How to test BOOT_COMPLETED without restart emulator or real device?
It's easy. Try this:
adb -s device-or-emulator-id shell am broadcast -a android.intent.action.BOOT_COMPLETED
How to get device id? Get list of connected devices with id's:
adb devices
adb in ADT by default you can find in:
adt-installation-dir/sdk/platform-tools
Enjoy! )

Looks like the name in the receiver section is wrong. This is what my application entry in the AndroidManifest.xml looks like:
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:name=".BootListener"
android:enabled="true"
android:exported="false"
android:label="BootListener">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name=".UpdateService">
</service>
<activity android:name=".Info"
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=".TravelMapperPreferences"
android:label="Settings">
</activity>
</application>
Note that the names are relative to the package in the manifest declaration. Your receiver name should be ".MyBroadcastReceiver" since the package of the manifest contains james.jamesspackage

Custom Intent Broadcast not working

I'm trying to send a custom intent to my service that is based off IntentService but when I do context.sendBroadcast nothing seems to happen. I've checked through the logcat logs and can't even see the intent resolution failing.
My service registration in my Android.xml is
<service android:name=".Service.FbSlideShowService" android:enabled="true" >
<intent-filter>
<action android:name="com.test.fbslide.UPDATE_WALLPAPER" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</service>
I'm trying to send the broadcast from a helper class on my activity thread and passing in context using, I've tried sending it in 2 ways:
Intent changeWallpaperIntent = new Intent(mContext, FbSlideShowService.class);
mContext.sendBroadcast(changeWallpaperIntent);
And
Intent changeWallpaperIntent = new Intent(FbSlideShowService.UPDATE_WALLPAPER_INTENT, null);
mContext.sendBroadcast(changeWallpaperIntent);
But the broadcast just doesn't work.
Any ideas?

sendBroadcast works when you have a BroadcastReciever. But what you have here is a sevice
<service android:name=".Service.FbSlideShowService" android:enabled="true" >
<intent-filter>
<action android:name="com.test.fbslide.UPDATE_WALLPAPER" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</service>
Your manifest entry tells that it is a service
You need to use mContext.startService() to start the service.
If you want to start a service when device boots you can refer this answer.
