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 am trying to launch my application when I turn my android device on. Currently I have a BroadcastReciever class and a Service class however the app does not seem to launch when I reboot my device.
My BroadCast Receiver Class
public class Bootup extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) {
Toast.makeText(context, "Reboot completed! Starting your app!!!.", Toast.LENGTH_LONG).show();
Intent i = new Intent(context, AutoStart.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startService(i);
}
}
}
My Service class
public class AutoStart extends Service {
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"

Could someone point me in the right direction. I am not sure what I am doing wrong.
Your application needs to be manually run at least once before boot receiver start working, also boot intent might be send after quite some time and maybe even intercepted and killed by other apps. I encountered such behaviour with few third party sms apps.
I'm not entirely sure about this, but try removing the android:exported="false" from the BootBroadcastReceiver. android:exported="false" means no other app can call it, and the system is just as an app in here.
Try using context.startActivity(i); instead of context.startService(i);.
You should correct this line in your BroadCast Receiver Class:
Use: context.startActivity(i);
Instead of: context.startService(i);
I see this has been asked quite a bit, but I can't seem to resolve my problem with what is out there.
My onReceive() method in broadcast receiver isn't being called.
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app.test"
android:versionCode="1"
android:versionName="1.0" >

BootUpReceiver.java
package com.app.test;
public class BootUpReceiver extends BroadcastReceiver {
private static final String TAG = "TESTAPP_BootUpReceiver";
#Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, "helllllllllllllllo");
Toast.makeText(context, "boot completed received", Toast.LENGTH_LONG).show();
// Intent i = new Intent(context, TestActivity.class);
// i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// context.startActivity(i);
}
}
Have tried using the entire path instead of .BootUpReceiver, didn't work. Not seeing anything from logcat or any Toast messages. Going into adb shell and emitting the boot_completed event that way doesn't help as the device then reboots.
Is there anything I am doing wrong? I read something about applications being inactive when device boots, does that affect my problem?
Here are some reference in Android developer website
http://developer.android.com/guide/topics/data/install-location.html
Broadcast Receivers listening for "boot completed"
The system delivers the ACTION_BOOT_COMPLETED broadcast before the external storage is mounted to the device. If your application is installed on the external storage, it can never receive this broadcast.
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.
So I am trying to develop a custom lockscreen
but my broadcastreceiver won't fire
my manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.alexander.fuchs.lockscreen"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".app"
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=".myreceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_OFF"/>
<action android:name="android.intent.action.SCREEN_ON"/>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>
my receiver :
public class myreceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("receiver","works");
Toast.makeText(context,"works",Toast.LENGTH_LONG).show();
Intent in=new Intent(context,app.class);
context.startActivity(in);
}
}
the receiver should show me that it is fired :D
but ther aren't any logs in logcat
well , for the screen off and screen on , this cannot be inside the manifest , but only at runtime . see this:
http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/
for the bootup , it must be in the manifest , so something else is wrong with it.check the path of the class. this is surely the cause of the problem.
