I've tried:
This which doesn't work on my phone:
Trying to start a service on boot on Android
This which also fails to work properly:
http://www.compiletimeerror.com/2014/12/android-autostart-app-after-boot-with.html#.VpL6sxWLTIU
And a few others which I couldn't find again. Could someone please post a working example of code which will start a MainActivity with the default HelloWorld xml layout?
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"

package com.example;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
context.startService(startServiceIntent);
}
}
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MyService extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_service);
}
}
First：create a BroadcastReceiver, onReceive(Context context, Intent intent)，start the app you want to startup in this method
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
xxx.class is the app you want to start
Intent service = new Intent(context,XXXclass);
context.startService(service);
Log.v("TAG", "you want to startup this app.....");
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
context.startActivity(intent );
} }
Secondly:configure receiver and intent-filter
<receiver android:name="BootBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
THirdly,add permission
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

I have a problem with running the service. In the logs there is nothing to see that the service is running. So I don't know that she works. Toast also does not show in MainActivity. I read a lot of posts and none work. How to fix it?
Service
import android.app.Service;
import android.os.IBinder;
import android.widget.Toast;
import android.content.Intent;
public class AutoStartUp extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
// do something when the service is created
}
}
BroadcastReceiver
import android.content.Context;
import android.content.BroadcastReceiver;
import android.content.Intent;
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, AutoStartUp.class);
context.startService(serviceIntent);
}
}
}

You don't have to verify the intent type since the
Receiver is registered with only one intent type(Intent.ACTION_BOOT_COMPLETED). So there is no need to check in the receiver if the intent action is Intent.ACTION_BOOT_COMPLETED.
I think the condition in the receiver is not true and because of that the code that starts your service is not executed.
I am simply trying to implement the AlarmManager. I wrote the code for alarm manager but the code doesnot work. AlarmManager doesnot fire the Broadcast Receiver and service. But when I donot use the AlarmManager and simply start the service using intent the service run. How to make AlarmManager work to schedule the service periodically?
Below is the code:
MainActivity.java
package com.alarmmanager;
import android.app.*;
import android.os.Bundle;
import android.content.*;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(this,AlarmReceiver.class);
PendingIntent pending =PendingIntent.getService(this, 0, intent, 0);
AlarmManager alarm =(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(),15000,pending);
}
}
AlarmReceiver.java
package com.alarmmanager;
import android.content.*;
public class AlarmReceiver extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
intent =new Intent(context,MainService.class);
context.startService(intent);
}
}
MainService.java
package com.alarmmanager;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class MainService extends Service
{
public IBinder onBind(Intent intent) {
return null;
}
public void onCreate() {
Log.i("nilavs","nilav");
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
}
}

You should use getBroadcast instead of getService?
PendingIntent pending =PendingIntent.getService(this, 0, intent, 0);
Edit:
Try setting it to fire off in the future initially - e.g.
alarm.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+5000,15000,pending);
I want my application to launch browser when boot my tablet but its crashing on boot time. If someone please let me know my mistake? I write nothing in my activity_main.xmle. Its showing me message "unfortunately the application crashed".

separate both classes and fix mainfest like below

write MainActiity
MainActivity {
...}
BootReceiver class
package com.example.BootReciever;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReciever extends BroadcastReceiver {
#Override
public void onReceive(Context ctx, Intent arg1) {
Intent iMainActivity = new Intent(ctx, yourMainActivityClass);
iMainStartActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(iMainActivity);
}
}
At a guess, I'd say it's probably because your manifest specifies .BootReceiver as the receiver, but based on your code the BootReceiver class is nested inside MainActivity. So you either need to move BootReceiver to a top-level class, or change your manifest to specify .MainActivity.BootReceiver as the receiver.
If that doesn't resolve it, please post your logcat so we can see what error is causing the crash.
Use this in the Manifest as receiver section:
<receiver
android:name=".BootReciever"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
And take care of Broadcast Receiver class that should be not inner:
package com.example.BootReciever;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReciever extends BroadcastReceiver {
#Override
public void onReceive(Context ctx, Intent arg1) {
Intent iMainActivity = new Intent(ctx, MainActivity.class);
iMainStartActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(iMainActivity);
}
}
Your app starts so quick and doesn't let other important apps to start first I think you should add some delay in your app to start up. like this:
public class BootUpReceiver extends BroadcastReceiver {
#Override
public void onReceive(final Context context, Intent intent) {
// We can't wait on the main thread as it would be blocked if we wait for too long
new Thread(new Runnable() {
#Override
public void run() {
try {
// Lets wait some time before starting the service to be fair to other processes on startup
Thread.sleep(5000);
} catch (InterruptedException e) {
}
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}).start();
}
I am testing the following app on HTC with Android 2.3.5. For some reason app is not launching on restarting or booting the phone.
I need to know where am I wrong exactly?
BootReciever.java
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
import android.widget.Toast;
public class BootupReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "App started", Toast.LENGTH_LONG).show();
/*
Intent startActivityIntent = new Intent(context, MainActivity.class);
startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startActivityIntent);
*/
// context.startActivity(new Intent(context, MainActivity.class));
}
}
MainActivity.java
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.content.BroadcastReceiver;
import android.widget.Toast;
import android.content.Intent;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

The code is working on restart but not on turning on the phone after shutting it down. Here are the messages that I receive in my logcat:
You extended BootupReceiver with Activity?
It should be extended with Broadcast Receiver.
public class BootupReceiver extends BroadcastReceiver{
}
Your Receiver:
public class AutoStartBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent receivedIntent) {
context.startActivity(new Intent(context, YourActivity.class));
}
}
Your Manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name="com.example.receiver.AutoStartBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Good luck!
You need to write following permission,
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
If your application is stored on External storage then you should provide following intent filter,
<receiver android:name=".BootupReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>

I am new to android, i am trying a broadcast demo, I gave my best effort by reading the documentation but its not working. Please have a look at my code:
BroadcastDemoActivity.java
package com.broadcastdemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class BroadcastDemoActivity extends Activity {
/** Called when the activity is first created. */
public static final String PUBLIC_HOLIDAYS = "com.paad.action.PUBLIC_HOLIDAYS";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(getIntent());
}
}

I know that i am missing something which i am not aware of, please help.
I believe your problem is in the call to sendBroadcast.
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(getIntent());
You are not sending the intent that you construct, you're sending the intent returned from getIntent(), which will be the intent that the activity was started with.
It should be
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(intent);
