hi i have used the following code in receiver class
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("the time is right","yay!");
Intent i = new Intent(context, AlarmServie.class);
context.startService(i);
}
}
here i the code which i used in service class
public class AlarmServie extends Service {
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
Log.e("onStart:","came" );
/* NotificationManager notifyman = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent main_activity = new Intent(this.getApplicationContext(), MainActivity.class);
PendingIntent o = PendingIntent.getActivity(this, 0, main_activity, 0);
/*Notification noti = new Notification.Builder(this)
.setContentTitle("Reminder to Pill")
.setContentText("Click for info")
.setAutoCancel(true)
.setContentIntent(o)
.build();*/
NotificationManager nm = (NotificationManager) this.getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
Intent in = new Intent(this.getApplicationContext(), MainActivity.class);
PendingIntent pending = PendingIntent.getactivity(this, 0, in, 0);
NotificationCompat.Builder mBuilder =new NotificationCompat.Builder(AlarmServie.this);
mBuilder.setContentTitle("Pill Reminder");
mBuilder.setContentText("CLick here to View");
//mBuilder.setSound(sound);
TaskStackBuilder ts=TaskStackBuilder.create(this);
ts.addParentStack(MainActivity.class);
nm.notify(9999,mBuilder.build());
}}
i created this code to get notification.when i run the app the receiver class is triggered but it is not moving to service class to invoke notification.can anyone say whats wrong in the code or say me how to get notification using broadcast receiver and service in a detailed tutorial
here is the manifest file and say me where to put the code exactly
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>

please explain in detail what the problem in code.please tell exactly where to put the service tag
You must declare service in manifest also.
Intent to start service is sent to system then system tries to find right application component to handle this particular intent using information passed in manifest files.
It should be enough, but I'm not sure if you put service in the default package.
<application>
....
<service android:name=".AlarmServie"/>
....
</application>
Your Manifest should look something like this
<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"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
//here is your service
<service android:name=".AlarmServie" android:enabled="true"/>
<receiver android:name=".AlarmReceiver"></receiver>
<activity android:name=".Set"></activity><!-- ATTENTION: This was auto-generated to add Google Play services to your project for

This is part of a code that I combine together from google and youtube, to execute "turnOnLed" when the alarm go off. For some reason it doesnt execute and I don't know how to make it work. Can someone help? I've Google it, but no succes.
Thank you.
private void startAlarm(Calendar c)
{
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
if (c.before(Calendar.getInstance()));
{
c.add(Calendar.DATE, 1);
}
Intent intent = new Intent(this, Control.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,intent, 0);
alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(), pendingIntent);
}
public class Control extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
turnOnLed(); //method to turn on
}
}
And the Manifest.xml file:

I am writing an app that connects to an Arduino bluetooth device. The goal is for the Android user to receive a push notification if the phone leaves the range of the Arduino. This should occur regardless of whether the app is in the foreground or not. To do this, I am currently using a BroadcastReceiver in the Android Manifest. However, I am not receiving any such notifications.
Here is the Receiver class that implements BroadcastReceiver:
public class Receiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
String action = intent.getAction();
if (action.equals(BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED)) {
if (adapter.getState() == BluetoothAdapter.STATE_OFF) {
pushNotification(context);
}
}
}
public void pushNotification(Context context) {
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setAutoCancel(true);
builder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));
builder.setContentTitle("This is a notification!");
builder.setContentText("This is the notification text!");
builder.setSubText("This is the notification subtext!");
NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
}
And the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/>
<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=".Receiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.bluetooth.adapter.action.STATE_CHANGED" />
</intent-filter>
</receiver>
</application>
</manifest>
I'm fairly certain that the problem lies in the constants I am using in my logic. However, I'm not sure which ones I should use. As it is, the receiver is activated when ANY state change occurs to the Android Bluetooth, but I only want a notification when the connection is lost, which might not have anything to do with a state change of the Android Bluetooth receiver.
What should I do to make sure pushNotification() is called under these conditions?
You have register wrong intent.
<action android:name="android.bluetooth.adapter.action.STATE_CHANGED" />
This intent only indicate wheather the bluetooth is on and off.If you want to receive bluetooth devices connect state , you should use follow actions:
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" />
<action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
In you onRecive method:
if(TextUtils.equals(action,BluetoothDevice.ACTION_ACL_DISCONNECTED)) {
BluetoothDevice device = intent.getExtras()
.getParcelable(BluetoothDevice.EXTRA_DEVICE);
if (isYourDevice(device)) {
// to push your notification
}
}
I want to create an application in android , which after installation I need to set as default when ever the device is turned on .
I have tried the following
created a service ,
created a reciever to recieve boot completion event
It is not working actually.If I remove the launcher for MainActivity the it will show error saying
No Launcher activity found!
The launch will only sync the application package on the device!
my manifest file
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"

</application>
MyReceiver.java
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
Intent serviceIntent = new Intent(context, MyService.class);
context.startService(serviceIntent);
}
}
}
MyService.java
public class MyService extends Service {
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Intent i = new Intent(this, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(i);
}
return null;
}
}
You have to follow below steps for achieve this task:-
Make a service in your app(Run all time).
check your app is running or not in service.(Through package name)
if running then good other wise run with the help of service.
Try it.... its working fine in my app. :)
I am trying to send a push notification on a button click event. But don't know why, but it is not working. It doesn't show any error though. Can anybody find any error in the code?
public class Verify extends AppCompatActivity {
public static String TAG=Verify.class.getSimpleName();
NotificationCompat.Builder notification;
private static final int uniqueID=12345;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_verify);
notification=new NotificationCompat.Builder(this);
notification.setAutoCancel(true);
}
public void onVerify(View v)
{
this.defineNotification();
//other code follows
}
public void defineNotification()
{
notification.setContentTitle("Successfully Signed Up");
notification.setContentText("Hi, you just Signed Up as a Vendor");
notification.setWhen(System.currentTimeMillis());
Intent intent=new Intent(this,OtherActivity.class);
PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
notification.setContentIntent(pendingIntent);
NotificationManager nm=(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(uniqueID,notification.build());
//Log.i(TAG, "coming here in notification");
}
Here is the Android Manifest Code :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sachinparashar.xyz">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
android:allowBackup="true"

android:label="Vendor Details"
android:theme="#style/AppTheme"/>
<activity
android:name=".OrderTypes"
android:label="Orders"

</application>
change this :
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
with this :
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
Insted of
PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
use
PendingIntent pendingIntent=PendingIntent.getActivity(Verify.this,0,intent,0);
I am trying to catch a bluetooth device disconnection intent filter.
I added a log to the onReceive but it never reaches it and is not displayed in the logcat.
I suspect that the problem is with my manifest.xml configuration:
manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.company"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name="com.company.MyReceiver" android:enabled="true" android:exported="true">
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECT_REQUESTED" />
<action android:name="android.bluetooth.adapter.action.CONNECTION_STATE_CHANGED" />
<action android:name="android.bluetooth.adapter.action.DISCOVERY_STARTED" />
</intent-filter>
</receiver>
<activity
android:name=".BTActivity"
android:label="BTActivity" >
</activity>
</application>
</manifest>
MyReceiver extends BroadcastReceiver:
#Override
public void onReceive(Context context, Intent intent) {
Log.i("got-in", "got-in-");
// String action = intent.getAction();
BluetoothDevice device = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
Log.i("disconnect", device.getName());
Intent i = new Intent(context, BTActivity.class);
Bundle b = new Bundle();
b.putString("deviceName", device.getName());
intent.putExtras(b); // Put your id to your next Intent
context.startActivity(i);
// finish();
}
Use this code for receiving a disconnect (when Bluetooth is still turned on):
<intent-filter> <action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECT_REQUESTED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" />
</intent-filter>
Also you have to register a service that then registers a broadcast receiver for Bluetooth status change, so your app knows when Bluetooth was turned off and therefore discards all active devices, as you won't receive a ACL_DISCONNECT when Bluetooth is simply turned off.
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
IntentFilter filter = new IntentFilter();
filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED);
registerReceiver(bluetoothTurnedOnOff, filter);
return START_STICKY;
}
private final BroadcastReceiver bluetoothTurnedOnOff = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, -1) == BluetoothAdapter.STATE_OFF) {
[...]
For new users. it will works . Your manifest file looks
<receiver android:name="(package name).BluetoothReceiver" >
<intent-filter>
<action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" />
</intent-filter>
</receiver>
and your receiver will look like
else if (intent.getAction().equals(`enter code here`
BluetoothDevice.ACTION_ACL_DISCONNECTED)) {
// connection lost
Try removing the <category .../> from the intent-filter and try again.
Try android.bluetooth.device.action.ACL_DISCONNECTED action in intent filter. It should solve your problem.
