I want my application to be automatically launched when the system is started. Can anyone tell me how to do that?
Thanks in advance for the time you will spend trying to help me.
First, you need the permission in your manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Also, in your manifest, define your service and listen for the boot-completed action:
<service android:name=".MyService" android:label="My Service">
<intent-filter>
<action android:name="com.myapp.MyService" />
</intent-filter>
</service>
<receiver
android:name=".receiver.StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Then you need to define the receiver that will get the BOOT_COMPLETED action and start your service.
public class StartMyServiceAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent("com.myapp.MySystemService");
context.startService(serviceIntent);
}
}
}
And now your service should be running when the phone starts up.
Here is Complete working Example Code,
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.practice" android:versionCode="1" android:versionName="1.0">
<uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".AutoStartExampleActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="AutoStart"></receiver>
<receiver android:name=".AutoStart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
AutoStartExampleActivity File
package com.practice;
import android.app.Activity;
import android.os.Bundle;
public class AutoStartExampleActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
BroadcastReceiver Code,
package com.practice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AutoStart extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
System.out.println ( "Application Started" );
// put your TimerTask calling class here
try
{
Intent myIntent = new Intent ( context, AutoStartExampleActivity.class );
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
catch ( Exception e )
{
System.out.println ( " Error while Starting Activity " + e.toString() );
}
}
}

I am writing a simple Android program that initializes an Intent, using a class that extends Android's BroadcastReceiver. However, when I run my program, I receive the following error:
C:\Users\windows\AndroidStudioProjects\NotificationTest\app\src\main\java\com\example\notificationtest\MainActivity.java:60: error: cannot find symbol
Intent notificationIntent = new Intent(this, MatchNotification.class);
^
symbol: class MatchNotification
location: class MainActivity
1 error
This seems strange, considering that I have clearly defined MatchNotification in the same folder as MainActivity. Below is my MainActivity class:
package com.example.notificationtest;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent notificationIntent = new Intent(this, MatchNotification.class);
}
}
And below is my MatchNotification class:
package com.example.notificationtest
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.media.MediaPlayer
import android.media.RingtoneManager
import android.net.Uri
class MatchNotification : BroadcastReceiver() {
private lateinit var player: MediaPlayer;
private lateinit var context: Context;
override fun onReceive(context: Context, intent: Intent) {
this.context = context
// Retrieve the URI of the alarm the user has set
var ringtoneUri:Uri? = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE)
player = MediaPlayer.create(context, ringtoneUri)
player.start()
}
}
Below is my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.notificationtest">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".MatchNotification"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
</application>
</manifest>
Sending a broadcast Intent would rather look alike this:
Intent intent = new Intent();
intent.setAction("com.example.notificationtest.ON_MATCH");
intent.putExtra("data", "Nothing to see here, move along.");
sendBroadcast(intent);
Which requires the corresponding intent-filter added into the receiver:
<receiver
android:name="com.example.notificationtest.MatchNotification"
android:enabled="true"
android:exported="true">
<intent-filter>
...
<action android:name="com.example.notificationtest.ON_MATCH" />
</intent-filter>
</receiver>
Also run :lint and then fix all Kotlin interoperability issues it may complain about.
I am designing an android application in java and I would like it to launch when the smartphone starts up I of course registered a BroadcastReceiver for the BOOT event of my phone as explained here but it does not work on Android 10 if not for info it worked on Android 4.1.
Can you help me please ?

Cordially.
I need to know how to make an application that I created in Android and made in Android Studio runs automatically when the device boots.
The only thing I have found is this guide https://codigofacilito.com/articulos/auto-ejecucion-de-una-aplicacion-al-inicio-de-un-depositivo-con-android but it does not run when the device starts.

I'm trying to start my background service when the device boots, but nothing is happening. This is my code:

public class Autostart extends BroadcastReceiver {
#Override

Log.e("it.Test", "***** SERVER STARTING CALLED *****");
}
}

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class AppService extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onDestroy() {
Toast.makeText(this, "My AppService Stopped", Toast.LENGTH_LONG).show();
Log.e("it.Test", "***** SERVICE STOPPED *****");
}
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My AppService Started", Toast.LENGTH_LONG).show();
Log.e("it.Test", "***** SERVICE STARTED *****");
/*
MainActivity.calc();
MainActivity.save();
*/
}
}
When my phone boots I don't see any toast (I don't see either the "My AppService Started" nor the "My AppService Stopped" toast) and nothing gets logged by the application...
Anyone knows what I am doing wrong??
Thanks!
EDIT: Solution to the problem
After seeing the post Trying to start a service on boot on Android linked in an answer and after many debugging I found the solution to my problem :) Thank to everyone!
Modification to AndroidManifest.xml
Added inside <application>:
<receiver android:name="it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service
android:name="it.test.AppService"
android:enabled="true" />
Added also:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
[...]
android:installLocation="internalOnly">
Modifications to AppService.java
To make the service work, I had to override in the AppService class onStartCommand instead of onStart, so I completely removed the method onStart from my class.
New onStartCommand:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "My AppService Started", Toast.LENGTH_LONG).show();
Log.e("it.Test", "***** SERVICE STARTED ***** from onStartCommand");
MainActivity.calc(this);
MainActivity.save();
return Service.START_REDELIVER_INTENT;//todo I'm not sure about what I have to return
}
Your broadcast receiver is not registered at AndroidManifest.xml
You need to register the broadcast receiver:
<receiver android:name=".<RECEIVER_NAME>">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
If your app is installed to external storage it won't receive BOOT_COMPLETE broadcast message. To prevent this you can install your application in internal storage. you can do this just adding this line in AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="internalOnly"
... >
Source: https://stackoverflow.com/a/32938071/1549700
You have you register your broadcast receiver and service under the <application> tag
<!-- [START service_listener] -->
<service
android:name=".it.test.AppService"
android:enabled="true" />
<!-- [END service_listener] -->
<!-- [START broadcast_receiver] -->
<receiver android:name=".it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- [END broadcast_receiver] -->
You need to register the broadcast receiver:
<receiver android:name=".Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
You need this in your manifest file:
<receiver android:name=".it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
Have you register broadcast receiver in manifest file and also also give boot completed permission in your broadcast receiver, if any problem then ask in comment, your code is perfect.
I have tried this on a few android phones with no luck (i did start the app once).
This was mostly generated from android studio 1.3.2 and from some questions like this and that and the other.
Perhaps someone can point out what i am doing wrong.
Thanks
edit: moved receiver inside app, but no joy.
edit2: added missing permissions for receiver. now seems to work on a nexus 4. but not on the kindle fire or the at&t tablets. although it seems to come right away if i press the circle icon on the azpen.
edit3: seems to work sometimes on the fires now.

Every Component must be declared inside application tag into manifest. Here you declared receiver outside of application tag. Read Structure of the Manifest File.
Correct manifest wil be
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="acme.startup" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".BootReceiver"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
You have to add permission to manifest file. Add this before your <application> tag :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
