I am trying to start a foreground service at boot time, but it never starts, however If i try to start a normal background service. It starts perfectly fine.
Can you please let me what is wrong with my code ?
My code is:
Manifest file:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name="com.test.andsrvfg.AndSrvFgService">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name="AndSrvFgService">
<intent-filter>
<action android:name="com.test.andsrvfg.AndSrvFgService"></action>
</intent-filter>
</service>
</application>
BroadcastReceiver to handle ACTION_BOOT_COMPLETED:
public class AndSrvFgStarter extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Intent i = new Intent();
i.setAction("com.test.andsrvfg.AndSrvFgService");
context.startService(i);
}
}
}
The actual service is like:
public class AndSrvFgService extends Service {
private boolean bForeground = false;
public AndSrvFgService() {
}
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if(!bForeground) {
bForeground = true;
Notification note = new Notification( 0, null, System.currentTimeMillis() );
note.flags |= Notification.FLAG_NO_CLEAR;
startForeground( 1242, note );
}
return START_STICKY;
}
#Override
public void onDestroy() {
if(bForeground) {
stopForeground(true);
}
}
This code works for me:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dfsdf"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<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>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
<service android:name=".MyService"/>
<receiver android:enabled="true"
android:name=".BootUpReceiver"
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>
</application>
</manifest>
Put this in the receiver:
android:permission="android.permission.RECEIVE_BOOT_COMPLETED"
Set enable to true:
android:enabled="true"

i am trying to read all current notifications.
Here is my Service:
public class MyService extends NotificationListenerService{
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
StatusBarNotification[] notifications = getActiveNotifications();
return super.onStartCommand(intent, flags, startId);
}
}
and my MainActivity:
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));
}
}
and of course my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ginso.stepwatcher">
<application
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>
<service android:name=".MyService"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
</application>
</manifest>
but when i debug the service, getActiveNotifications() returns null.
What am i doing wrong? do i miss any permissions? i am running it on Android 8.0
I am using a Broadcast reciever to auto start my app whenever phone is switched on. But it is not working in my case. I am attaching the program details. Please somebody help me, where am I lagging behind. Thanks in advance
this is manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.vishal.readsimnumber">
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<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=".reciever.BootStartReciever">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service
android:name=".FetchSimNumber"
android:enabled="true"
android:exported="true"></service>
</application>
</manifest>
this is my broadcast reciever
public class BootStartReciever extends BroadcastReceiver {
public BootStartReciever() {
}
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context, FetchSimNumber.class);
context.startService(pushIntent);
}
}
}
this is my service class
public class FetchSimNumber extends Service {
public FetchSimNumber() {
Intent intent = new Intent(FetchSimNumber.this,MainActivity.class);
startActivity(intent);
}
#Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
}
and this is my main activity
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyManager telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
String getSimNumber = telemamanger.getLine1Number();
((TextView) findViewById(R.id.tv1)).setText(getSimSerialNumber);
((TextView) findViewById(R.id.tv2)).setText(getSimNumber);
}
}
public class BootStartReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
/* Setting the service here */
Intent i = new Intent(context, Yourservice.class)
context.startService(i);
}
and in your manifest file:
<receiver android:name=".BootReceiver"
android:enable="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
sometimes category.HOME not work so you can use category.DEFAULT also.. i dont know the reason behind this, but its working fine..
AndroidManifest.xml
<receiver android:name=".Receiver">
<intent-filter android:priority="1000000">
<action android:name="android.intent.action.ACTION_SHUTDOWN" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
Receiver.xml
public class Receiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase("android.intent.action.BOOT_COMPLETED")) {
**do your stuff at here...**
}
}
I was debugging my app and I have experienced an interesting issue. I had a breakpoint in my onReceive method and the program has stopped there only when screen of my phone was turned on (awake).
Why is that?
If by any chance you would need my code:
private void gcmInit() {
mRegistrationProgressBar = (ProgressBar) findViewById(R.id.registrationProgressBar);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
mRegistrationProgressBar.setVisibility(ProgressBar.GONE);
SharedPreferences sharedPreferences =
PreferenceManager.getDefaultSharedPreferences(context);
boolean sentToken = sharedPreferences
.getBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false);
if (sentToken) {
// mInformationTextView.setText(getString(R.string.gcm_send_message));
} else {
// mInformationTextView.setText(getString(R.string.token_error_message));
}
}
};
if (checkPlayServices()) {
// Start IntentService to register this application with GCM.
Intent intent = new Intent(this, RegistrationIntentService.class);
startService(intent);
}
}
Plus I have also these 2 methods in my MainActivity:
#Override
protected void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(QuickstartPreferences.REGISTRATION_COMPLETE));
}
#Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
super.onPause();
}
My Manifest, where I register the receiver:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">

Any suggestion/fix would help me lot.
Late answer, but try changing
android:exported="false"
to
android:exported="true"
I'm trying to call a service from a activity:
When I'm running the program the activity throws an error which says: Not allowed to start service Intent. What am I doing wrong? I'm sorry for possible stupid mistakes in the code, but I'm a newbie.
activity code:
public void startService() {
try {
startService (new Intent ( this , SmsReminderService.class)) ; }
catch (Exception e ) { Log.v("Error" , e.getMessage()) }
}
service code :
public class SmsReminderService extends Service {
#Override
public void onStart(Intent intent, int startid) {
Log.v("SSms", "Service started") ; }}
manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.sms.smsReminder"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<permission android:name="SEND_SMS"></permission>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:label="#string/app_name"
android:name=".SmsReminderActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".SmsReminderService"
android:permission="android.permission.BIND_REMOTEVIEWS">
<intent-filter>
<action android:name = "android.intent.category.LAUNCHER" ></action>
</intent-filter>
</service>
</application>
</manifest>
Thanks in advance, Tom
Why this in the service?
<intent-filter>
<action android:name = "android.intent.category.LAUNCHER" ></action>
</intent-filter>
Try to add this:
<uses-permission android:name="android.permission.BIND_REMOTEVIEWS" />
