Hello everyone and thanks for your trouble,
I have a program detailed here. This uses a microphone icon in order to start listening for voice. However, I want this program to run immediately on start up of the device. How is this possible? Also, I want the program to run without any visuals and simply return the text translation to my running program, which will take care of what command to execute. Any help on any of these topics? It will be greatly appreciated.
Yes you can do it. For this you'll need set permission to AndroidManifest.xml.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
In your AndroidManifest.xml, define your service and listener 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 have 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 (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Intent serviceIntent = new Intent(context, MySystemService.class);
context.startService(serviceIntent);
}
}
}
Hope this helps .. :)

So, I have an alarm application which works good and behaves normally as long as the device remains online until the alarm time.
Problem is, let's say I ran out of battery, or I just want to restart the device... the alarm won't fire upon its time.
I tried something like:
public class BootCompletedReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
Utils.set_alarms(context);
}
}
}
In my BroadcastReceiver... but doesn't seem to work. Oh, and it's registered in the AndroidManifest too...:
<receiver
android:name=".receivers.AlarmReceiver" // The receiver which starts the alarm activity.
android:enabled="true" />
<receiver
android:name=".receivers.BootCompletedReceiver" // The receiver which is supposed to set the alarms after the device is online again.
android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
But doesn't work... help will be appreciated.
You probably need to add the permission to receive boot completed to your manifest. See Manifest Permission: RECEIVE_BOOT_COMPLETED
Add below permission and actions
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver
android:name=".receivers.BootCompletedReceiver" // The receiver which is supposed to set the alarms after the device is online again.
android:enabled="true">
<intent-filter>
<!-- used for restart or reboot -->
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<!-- Used for cold boot -->
<action android:name="android.intent.action.BOOT_COMPLETED" />//cold start
</intent-filter>
</receiver>
I have written an Android application for a large store for the purposes of production inspection. I have a few Android tablets with the app installed on each that will be provided to the store.
As the only purpose of this tablet is to run a single app, is there a way to force this app to load upon switching on the tablet, and only allow this app to be used? The app does require an active 4G connection so it still needs to use a few of the core functions of Android as well as actually running the app.
I don't know much about this so apologies for naivety in advance, but could someone please shed some light on this for me?
First, you need the permission in your AndroidManifest.xml:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Also, in yourAndroidManifest.xml, 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: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 StartMyActivityeAtBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Intent serviceIntent = new Intent(context, MyActivity.class);
context.startService(serviceIntent);
}
}
}
I want to run an application automatically when the phone reboot. I have added these lines to my code:
public class BootComplete extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) {
Intent serviceIntent = new Intent(context, MyActivity.class);
context.startService(serviceIntent);
}
}
And I have added these lines to my Manifest :
<receiver
android:name=".BootComplete"
android:enabled="true"
android:exported="false" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
and it's permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" >
</uses-permission>
It works properly when MyActivity class contains just some background tasks. For example when I want to turn on a LED. But when I want to play a media (ex. a video) it doesn't work. Just says service has started and doesn't play anything.
How can I fix it? Is there anything that I must add to the code?
The problem is not with your code! It's about android device.
When the device boot up, you receive the broadcast. But pay attention, when you receive that broadcast, the SD CARD is still populating and you can't access it. If that media is on SD card you cant play it.
Also, you should pay attention to something else: if the user install your app in his/her SD card, that broadcast receiver would never trigger.
So, if you want to prevent problem in some devices, in your manifest, choose internal for your install location too.
Do this change in BroadcastReceiver:
public class BootComplete extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) {
Intent serviceIntent = new Intent(context, MyActivity.class);
// Change is here...
serviceInten.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startService(serviceIntent);
}
}
In the manifest:
<receiver
android:name=".BootComplete"
android:enabled="true"
android:exported="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter android:priority="500">
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
And leave permission as it is.
I want to start my application automatically when the phone boots.
I declared a BroadcastReceiver in the manifest file.
<receiver android:name=".Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
I made a java file for the receiver.
Autostart.java
public class Autostart extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context, MushTouchActivity.class);
pushIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(pushIntent);
}
}
}
But, the application does not launch when I switch my phone on. Can anyone tell me what I am missing here ?
try your if statement like this:
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
Intent i = new Intent(context, MushTouchActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
In case you are on Android 3.1 or newer:
Make sure that you started your application at least once manually (e.g. by opening it from the app drawer). Otherwise your app is marked as stopped by the system:
Applications are in a stopped state when they are first installed but are not yet launched
Stopped apps do not receive any broadcast intents, including BOOT_COMPLETED.
See Android 3.1. Platform - Launch controls on stopped applications for more information.
The best answer would be to show a Notification and ask the user to launch the app from that notification and use a pending intent for that activity in the notification.
Tested on Android 10
1. Create A Broadcast Listener
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction() == "android.intent.action.ACTION_SHUTDOWN") {
// Your tasks for shut down
} else {
// Your tasks for Boot up
}
}
}
2. Config Manifest
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:theme="#style/AppTheme">
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.ACTION_BOOT_COMPLETED" />
<action android:name="android.intent.action.REBOOT" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<action android:name="com.htc.intent.action.QUICKBOOT_POWERON" />
<action android:name="android.intent.action.ACTION_SHUTDOWN" />
</intent-filter>
</receiver>
</application>
If you search for a sample application code for working with services in background and control actions on screen off/on then visit this repo:
https://github.com/varunon9/DynamicWallpaper
you can update this repo source code with step 1 and 2 for control boot and shutdown events in addition to screen on/off.
I want to launch an application immediately after the screen gets unlocked and at the time of booting. How is it possible? What changes do I need to make?
To launch your application when the screen locks, you need to register a BroadcastReceiver for the Intent.ACTION_SCREEN_OFF Intent for more information check the example http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/
To launch your application at the time of boot you need a broadcast receiver that listens for the BOOT_COMPLETED action, please refer How to start an Application on startup?
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.
