I am trying to start an activity when am restart my phone then its open app or show me toast when booting is complete
class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) {
Intent serviceIntent = new Intent(context, MyIntentService.class);
context.startService(serviceIntent);
}
}
}
this is my Broadcaste receiver Code
class MyIntentService 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
}
}
This is my service Code.
Manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
am trying lots of diffrent code but no one work for me so can anyone help me to correct this code
Your BroadcastReceiver will never get called because you have this in the manifest entry for it:
android:exported="false"
Remove that.
NOTE: You also need to make sure that your app is started at least once manually after installing it on the phone. Otherwise your BroadcastReceiver will NOT get the BOOT_COMPLETE Intent.
NOTE: Also, using Toast as a debugging aid isn't a very good idea. You should write messages to the logcat and use that to determine if your Service is getting started, etc. Toast is not reliable as a debugging tool.
Add this in BroadcastReceiver class
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context, SyncData.class);
context.startService(pushIntent);
Log.e("BroadCast Received", "ON BOOT COMPLETE");
}
}
and remove this two lines android:enabled="true"
android:exported="false"

This is little snipet to try BroadcastReciever android but i dont understand wath's wrong.
In fact just callIntent return log. my little brain it's burning.
if somebody can tell me why ?
Sorry for my bad english !

```
No error, no crash, nothing !! :=(
Create an explicit intent by explicitly declaring the receiver when you create the intent. At present your intent is implicit.
public void callIntent() {
// Explicitly declare the receiver class
Intent intent = new Intent(this, MyReciever.class);
intent.setAction("com.plectre");
intent.putExtra("frist", "Intent premier" );
sendBroadcast(intent);
Log.i("callIntent", "Tag");
}
Additional reading: https://developer.android.com/guide/components/intents-filters#ExampleExplicit
Also. You declare the intent's Extra as "frist" and try to receive at as "first". This needs to be rectified.
You should ensure that the correct action is taken with the specified Intent Action in your receiver:
#Override
public void onReceive(Context context, Intent intent) {
if ("com.plectre".equals(intent.getAction())) {
final String result = intent.getStringExtra("first");
Toast.makeText(context, "Result", Toast.LENGTH_LONG).show();
Log.i("Broadcast", " Receiver");
}
}
I have a project which is only a service and it has no activity and user interface. I want to start my application background service when phone boot completely. but I never receive the "BOOT_COMPLETED" Message from OS. these are my code:
Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.droid.arghaman.location_tracker">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<receiver android:name=".BootBroadcastReceiver"
android:enabled="true"
android:exported="false"
android:label="StartServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.DEFAULT"></category>
</intent-filter>
</receiver>
</application>
<service android:name=".mySevice"></service>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
</manifest>
Broadcast Receiver:
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.i("boot Received", intent.getAction());
Intent serviceLuncher = new Intent(context, myService.class);
context.startService(serviceLuncher);
}
}
myService:
public class LocationNotifierService extends Service {
Timer timer ;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate(){
timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
Toast.makeText(getBaseContext(),"Location",Toast.LENGTH_SHORT).show();
}
},3000);
}
#Override
public void onDestroy(){
}
#Override
public int onStartCommand(Intent intent, int flagId, int startId){
return START_STICKY;
}
}
but I never get "boot Received" log.
is there any mistake and is there any way to debug my program?
I Recommend that my project must have only this Service and it cannot have any UI.
I never receive the "BOOT_COMPLETED" Message from OS
Partly, that is because you do not have a <receiver> set up to receive android.intent.action.BOOT_COMPLETED broadcasts.
Partly, that is because your app will not receive broadcasts until something on the device uses an explicit Intent to start one of your components. The way your app is set up — without an activity that the user can run — it is unlikely that any app will do this, and so your code will never run.
Also, please bear in mind that Android O has changes designed specifically to prevent background services from running for very long and to limit your ability to get background location updates (which your location_tracker name suggests that you want to add in the future). You may wish to reconsider whether writing this app the way that you are is a wise course.
try this in your manifest
<receiver android:name=".BootBroadcastReceiver"
android:enabled="true"
android:exported="false"
android:label="StartServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
I had created alarmmanager on button click. but it not working after phone reboot. my AlarmbroadcastReceiver not call on phone reboot. it work when phone lock , application killed but not work after phone reboot i had created one progressbar which start on button click and stop after alarm broadcast fired but it not stop when phone reboot. i had added my button click event and broadcast receiver class
Button click event
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pb1.setVisibility(View.VISIBLE);
progress_edit.putBoolean("progress_one", true);
progress_edit.apply();
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intnt = new Intent(getApplicationContext(), AlarmbroadcastReceiver.class);
intnt.setAction("com.ex.Alarm");
PendingIntent pending = PendingIntent.getBroadcast(getApplicationContext(), 0, intnt, 0);
manager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 120000, pending);
Log.d("Broadcast ","Fired");
}
});
BroadcastReceiver Class
#Override
public void onReceive(Context context, Intent intent) {
Log.d("inside","broadcast receive");
if(intent.getAction().equalsIgnoreCase("com.ex.Alarm"))
{
enterSys_progress_edit.putBoolean("progress_one", false);
enterSys_progress_edit.apply();
Toast.makeText(context,"Receive",Toast.LENGTH_LONG).show();
}
}
My Manifest file
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.krutarth.alarm">
<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="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=".AlarmbroadcastReceiver" android:enabled="true" android:exported="false" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>
all alarms are reset when phone restart ,So create a callback on reboot like this
public class BootCompletedIntentReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
////// reset your alrarms here
}
}
}
ALSO ADD THIS TO YOUR MANIFEST TO REGISTER THE BROADCAST
<receiver android:name=".receiver.BootCompletedIntentReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Create a method say,
setMyalarm(){
// here set the alarm as u need
}
now call this method setMyAlarm ,whenever and wherever u need to set that particular alarm,whether its on a button click or whether it on a reboot reciever
prefect ans by Ak9637
but didn't forgot to add permisttion of
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
I have used BootComplete and allow permission and it still cant autostart,then I try to use wake lock but it cannot work. Also, I try to make it as a service but the service does not pop up in my phone.Is there anything I missed?
public class BootComplete extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
{
// This is the Intent to deliver to our service.
Intent serviceIntent = new Intent(context, AutoStartUp.class);
context.startService(serviceIntent);
}
}
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
}
}
In my manifest file:
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<service android:name=".SimpleWakefulReceiver">
<intent-filter>
<action android:name="com.example.SimpleWakefulReceiver"/>
</intent-filter>
</service>
<receiver
android:name=".MainActivity$BootComplete"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name=".AutoStartUp">
</service>
Do whatever you intend in onReceive -
public class BootupReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Log.e("BOOTUP", "received notification ......................");
if(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED))
{
Log.e("BOOTUP","RECEIVED BOOT NOTIFICATION ........");
Intent start_service = new Intent(context,MainService.class);
context.startService(start_service);
}
}
in the Manifest add-
<receiver
android:name=".AutoStart"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
add permission-
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Also you need to launch your application from activity atleast once and your block should be outside block in manifest
So I have a boot receiver that is supposed to call an intent service but the receiver isn't registering at all.
Manifest file -
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<receiver android:name=".ClockReciever">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
ClockReceiver.java
public class ClockReceiver extends BroadcastReceiver {
private final String TAG = "ClockReciever";
#Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG,"onRecive");
context.startService(new Intent(context, RefreshIntentService.class));
}
}
I think this is correct, but according to my logcat the ClockReciever is never called and the program crashes with a "Unable to instantiate receiver" error.
Any suggestions? Thank you
Here you have a typo
<receiver android:name=".ClockReciever">
Should be ClockReceiver, i.e. same as your class.
Cheers!
