How to Start/ Launch Application at Boot Time Android

How to start/ launch application at boot time Android

These lines of code may be helpful for you...

Step 1: Set the permission in AndroidManifest.xml

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Step 2: Add this intent filter in receiver

<receiver android:name=".BootReceiver">
    <intent-filter >
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

Step 3: Now you can start your application's first activity from onReceive method of Receiver class

public class BootReceiver extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {
       Intent myIntent = new Intent(context, MainActivity.class);
       myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       context.startActivity(myIntent);
   }

}

How can I start android application on device boot?

After I added the boot permissions in manifest file (see code below), BroadcastReceiver started to get boot completed event and the service is starting successfully. For the solution to work (as suggested by @Eren Tüfekçi) I had to enable auto start permission in phone settings for my application. If anyone has a solution, how to enable it programmatically, please let us know. Thank you.

Is it possible to launch an Activity on startup in Android 11?

The larger goal is to tinker with a used Pixel 3a and turn it into a home utility device

Write a launcher app (i.e., have your activity respond to ACTION_VIEW/CATEGORY_HOME) and set it as your default launcher. It will automatically start when the phone starts, just as your current default launcher does. And, you can put a button or something in your own launcher that launches the real launcher via an explicit Intent.

This would allow you to skip the on-boot receiver and the service.

Why doesn't this start?

You do not qualify for a background activity start.

Google Maps most certainly has a visible window, so I am expecting to be able to start it.

First, presumably it does not have a visible window right after boot.

Second, you are not writing the Google Maps app, and Google Maps is not trying to start an activity from the background. You are writing your own app, and your own app is trying to start an activity from the background. And, since your own app does not have a visible window right after boot, it does not qualify for a background activity start under the "app has a visible window" rule.

Auto start application after boot completed in Android

You can use the shared preference to store a Boolean value for isAutoStartEnabled, and check this value in the BroadcastReciver, fire an intent only if it's true.

In your case, the problem is not whether you receive the broadcast but who receives the broadcast. Best of luck..

I hope it helps..

How to enable auto start automatically just after installing app from play store

From my understanding, this can't be achieved by every app. The apps you see, which are automatically auto-launching after installation are white-listed by manufacturers or Google themselves. All you can do is send the user to the specific settings to enable the auto-launch after installing the app. This is also described here:

Starting Android Service on Boot Time

This is not possible. When you install your app on a device, your components are all in the "stopped state". They will not be triggered by Android while in the "stopped state". In order to get your components out of this state, the user must, manually, start your app at least once. The only way for the user to start your app is to launch an Activity. And the only way for the user to launch an Activity is for you to have an Activity in your app, and a matching <activity> declaration in your manifest, with an <intent-filter> containing ACTION=MAIN and CATEGORY=LAUNCHER.
