I want to auto-start my service after device being rebooted as given on this website Example.
Created BroadCastReceiverBootUpComplete class to restart the service(MyService.java) after reboot, but it is not starting at all.
I want MyService.java to run as soon as device get rebooted.
MainActivity.java
package com.example.shubham.servicedemo;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this,MyService.class));
}
}
BroadCastReceiverOnBootComplete.java
package com.example.shubham.servicedemo;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BroadCastReceiverOnBootComplete extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)){
Intent serviceIntent = new Intent(context,MyService.class);
context.startService(serviceIntent);
}
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

If you are targeting android version 26 above then you have to use startforeground service
Intent mIntentForService = new Intent(context, MyService.class);
mIntentForService.setAction(intent.getAction());
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
context.startForegroundService(mIntentForService);
else
context.startService(mIntentForService);
check below link for more details
link
Note that this works, to an extent, even if your service does not actually
ever call startForeground(). You are given a window of time to get around
to calling startForeground(), "comparable to the ANR interval to do this".
If your work is longer than a millisecond but less than a few seconds,
you could skip the Notification and the startForeground() call.

I want to create an app that starts the service after rebooted, but I do not want to show the UI–just like the service run in the background silently. I can create it,but after rebooted the application crashes. Because, MainActivity had not launched and I don't want to launch any activity. How do I solve this problem?
My manifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.galleryapp">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.CAMERA" />
<application
android:name=".App"
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=".CameraEventReceiver"
android:enabled="false">
<intent-filter>
<action android:name="com.android.camera.NEW_PICTURE" />
</intent-filter>
</receiver>
<receiver android:name="com.galleryapp.RebootDeviceReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service
android:name=".BackgroundService"
android:exported="true" />
</application>
And my receiver class:
public class RebootDeviceReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent serviceIntent = new Intent(context, BackgroundService.class);
context.startService(serviceIntent);
}
}
You need to write a BroadcastReceiver and register it in your Manifest file.
<receiver android:name="your.package.BootCompletedReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
From your BroadcastReceiver you can then start a service. For example, in my code I'm using a JobIntentService.
public class BootCompletedReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent msgIntent = new Intent(context, MyJobIntentService.class);
msgIntent.setAction(MyJobIntentService.ACTION_RESCHEDULE);
MyJobIntentService.enqueueWork(context, msgIntent);
}
}
If you want your service to run for a longer amount of time, you need to run it as a foreground service, at least for newer Android versions.
I've read some of the threads here explaining about launching an app after startup such as this one but it didn't work for me.
Here is MainActivity.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
AfterBootReceiver.java:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class AfterBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("Intent.ACTION_BOOT_COMPLETED")) {
Toast.makeText(context, "AfterBootReceiver - boot", Toast.LENGTH_SHORT).show();
}
}
}
Here is the manifest with the permission code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.liorle.startappafterboot">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="false"
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=".AfterBootReceiver">
<intent-filter>
<action android:name= "android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
My questions is: does any of you see any problem with this code? how to make the receiver receive the boot action from within the main activity?
Thanks!
You will need to register the receiver outside of your main Activity (in your Manifest), Android will not know that your BroadcastReceiver exists until your Activity is started. You will also need to create your own BroadcastReceiver implementation for this purpose.
<receiver android:name=".BootCompletedReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
You may start yourt main Activity from inside your newly created BroadcastReceiver (BootCompletedReceiver).
Your application will also need to request the RECEIVE_BOOT_COMPLETED permission.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Your launcher is not listening for the BOOT_COMPLETED broadcast.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
In your apps current state - the main activity needs to be running to listen to the BOOT_COMPLETED broadcast. Your manifest needs to have something registered that tells the ecosystem to activate the activity / receiver.

i want to created an app for saving call history

}
For security reasons you have to run app at least once after install to get the BroadcastReceiver working.

I am trying to get my app to auto start on boot up and it will and an error occurs while launching the application
Here is my manifest and the program file for the "Auto Starter":
manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="this.bad.file"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name="autoBot"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
Here is the "AutoBot" as I have called it (Not for spammy reasons I just like transformers):
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class autoBot extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
So there we have it!
In your manifest, you left out a vital name of the class, usually, can be abbreviated to [dot][ClassName] or the full package name, as in for example .autoBot or see the example below:
<receiver android:name="this.bad.file.autoBot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And in your Broadcast receiver:
public class autoBot extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
Notice the usage of #Override on the onReceive class.
The normal recommended route to take is usually, to start an alarm on boot, and listen for the broadcast when the alarm has expired, in that way your activity does not hog up the boot and also, allow the boot up process to "settle" for a bit.
I am new to android development, and
I have an app that when run from the app icon in the menu / home screens runs just fine. However when I try to make it run on boot completion it crashes (Keeping in mind that if I go back to the Icon it will still work) I am wondering what is wrong here. Keep in mind I am doing testing on my personal phone which is android 2.3 and it is ROOTED. Some how I don't think this should be as hard as it is to do, since 9/10 most android apps work in this way or in a way similar to this. Simply put: What am I doing wrong?
In the mean time here is my code for the Broadcast Receiver:
package path.to.file;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class autoBot extends BroadcastReceiver {
private static final String LOG_TAG = "StartAtBootServiceReceiver";
#Override
public void onReceive(Context context, Intent intent) {
Log.e(LOG_TAG, "onReceive:");
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Intent i = new Intent();
i.setAction("path.to.file.MainActivity");
context.startActivity(i);
}
}
}
As well as the Manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
installlocation="internalOnly"
package="path.to.file"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="autoBot" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" >
</action>
<category android:name="android.intent.category.HOME" >
</category>
</intent-filter>
</receiver>
</application>
</manifest>
Is there a specific reason you are adding an action to your intent? If your only aim is to launch your activity at start-up, do this in your BroadcastReceiver:
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Also, remove these lines from your manifest under receiver tag, you won't need them there:
<category android:name="android.intent.category.HOME" ></category>
