I am trying to send an Intent from the onCreate in an Activity to start an IntentService. However the IntentService's onHandleIntent is never being received. I have tried changing around the Manifest with Intent-filters but nothing seems to be working. No exceptions are being thrown, but the IntentService is simply not called.
Here is the onCreate
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
db = new TwitterDB(this);
String[] columns = new String[1];
columns[0] = TwitterDB.TEXT;
tAdapter = new SimpleCursorAdapter(this, 0, null, columns, null, 0);
tweets = (ListView)findViewById(R.id.listtwitter);
tweets.setAdapter(tAdapter);
Intent intent = new Intent(this, SyncService.class);
intent.putExtra("action", SyncService.TWITTER_SYNC);
this.startService(intent);
}
Here is the creator and onHandleIntent of the IntentService class, I know it is not being called because logcat never shows "Retrieved intent". The constructor is not called either (There was a log call in there, but I removed it.
public SyncService(){
super("SyncService");
twitterURI = Uri.parse(TWITTER_URI);
Log.i("SyncService", "Constructed");
}
#Override
public void onHandleIntent(Intent i){
int action = i.getIntExtra("action", -1);
Log.i("SyncService", "Retrieved intent");
switch (action){
case TWITTER_SYNC:
try{
url = new URL(twitterString);
conn = (HttpURLConnection)url.openConnection();
syncTwitterDB();
conn.disconnect();
}catch(MalformedURLException e){
Log.w("SyncService", "Twitter URL is no longer valid.");
e.printStackTrace();
}catch(IOException e){
Log.w("SyncService", "Twitter connection could not be established.");
e.printStackTrace();
}
break;
default:;
// invalid request
}
}
And here is the Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service android:name="SyncService"/>
</activity>
</application>
</manifest>
Move your service declaration outside of the scope of the TwitterTwoActivity in the XML file, as I have done here:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="SyncService"/>
</application>
</manifest>
You need to define the path to the service in your manifest, simply putting the name is not sufficient.
Change
<service android:name="SyncService"/>
to
<service android:name=".SyncService"/>
if SyncService is in the root of your package, add respective folder before .SyncService if needed.

I followed a tutorial on Receiving sms using BroadcastReceiver
https://www.youtube.com/watch?v=h-zYXVODiPo
I used exactly the same codes. Enabled Telnet client. Does my device need to be rooted first? I don't know the problem. Please help.
Here's my MainActivity
public class MainActivity extends Activity {
BroadcastReceiver receiver;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arr0, Intent arr1) {
processReceiver(arr0,arr1);
}
};
registerReceiver(receiver,filter);
}
public void onDestroy(){
super.onDestroy();
unregisterReceiver(receiver);
}
public void processReceiver(Context context,Intent intent){
Toast.makeText(context,"RECEIVED",Toast.LENGTH_LONG).show();
TextView lbs = (TextView)findViewById(R.id.textView1);
Bundle bundle = intent.getExtras();
Object[] objArr = (Object[])bundle.get("pdus");
String sms="";
for(int i=0;i>objArr.length;i++){
SmsMessage smsMsg = SmsMessage.createFromPdu((byte[])objArr[i]);
String smsBody = smsMsg.getMessageBody();
String senderNumber = smsMsg.getDisplayOriginatingAddress();
sms+= "From: "+senderNumber+"\nContent: "+smsBody+"\n";
}
lbs.setText(sms);
}
Here's my Manifest.XML
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="gavadev.com.smsreceiver">
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21"/>
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<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>
<activity android:name=".Main2Activity"></activity>
</application>
</manifest>
Use a Broadcast Receiver which will not be unregistered when destroying the activity:
public class MyReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED"))
{
// your processing will go here...
}
}
}
Register the receiver via manifest file as following:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.broadcastreceiverpremier"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.broadcastreceiverpremier.MainActivity"
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.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
</application>
I have an application A that has to bind to a service that is in another package. I have put a custom intent filter in order to make it work. Sadly the application wont bind. The log says that it can't find the service.
Application A is in the package "com.example.app_a"
The service is in another package "com.example.app_talker_service"
So I just can't refer to the service with the xxx.class solution, so my guess was to use an intent filter in the manifest file of the service's package.
Application A, on the other hand, will need to do a bind to the service to make it start (if it hasn't already started) and that later it will communicate with it though the use of broadcast receivers. I did some experimentation and I noticed that the broadcasts work fine, but what is wrond is that for some reason, the application A can't seem to find my service during the binding....
Here is the code for application A which binds in onStart():
#Override
protected void onStart()
{
// TODO Auto-generated method stub
super.onStart();
//Bind to service
getApplicationContext().bindService(new Intent("com.example.talker_service.SERVICE"), mConnection,Context.BIND_AUTO_CREATE);
}
private boolean mIsBound = false;
private ServiceConnection mConnection = new ServiceConnection()
{
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
mIsBound = true;
Toast.makeText(getApplicationContext(), "CONNECTED TO SERVICE!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setAction("com.example.talker_service.SERVICE");
intent.putExtra("REQUEST", "REGISTER APP");
intent.putExtra("FILTER", "com.example.app_a");
intent.putExtra("NAME", "Applicazione A");
String[] components = {"NUMBER_SENT","CHANGE_TEXT_COLOR","CHANGE_TEXTVIEW_SIZE"};
intent.putExtra("COMPONENTS", components);
MainActivityA.this.sendBroadcast(intent);
}
#Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
mIsBound = false;
}
};
Here instead is the cmanifest for the service which I called Talker_service:
en<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app_talker_service"
android:versionCode="1"
android:versionName="1.0" >

android:minSdkVersion="14"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"

android:theme="#style/AppTheme" >
<service

android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
<intent-filter >
<action android:name="com.example.talker_service.SERVICE"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain" />
</intent-filter>
</service>
<activity
android:name=".ConnectionManagerActivity"
android:label="#string/title_activity_connection_manager" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I don't undertsand why it doesn't bind.. I put the intent filter, am I missing something? Ah, and the logs says this:
12-03 22:45:13.786: W/ContextImpl(26076): Implicit intents with startService are

12-03 22:45:13.786: W/ActivityManager(764): Unable to start service Intent { >act=com.example.talker_service.SERVICE } U=0: not

This instead is the manifest file for application A
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app_a"
android:versionCode="1"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I don't know why using intent filters is not working (it says that it can't find it) but by using the following code I was able to make my application connect to the remote service:
Intent i = new Intent();
i.setClassName("com.example.app_talker_service", "com.example.app_talker_service.Talker_Service");
bindService(i, conn, Context.BIND_AUTO_CREATE);
so using the seClassName method and providing the name of the pacake and that full path of the service, I was able to make it work. I am not sure if this falls in the realm of "best practice" for this type of problem, but for my it worked. Any solution is better than no solution. I found this solution thants to this link:

I know there are similar question in statckoverflow, but they just do NOT work for me.
Broadcast receiver(staticly registe via manifest.xml) can NOT receive package_remove event after installing on device (without running main activity)
But the receiver works if main activity is running.
To register broadcastreceiver staticly in AndroidManifest.xml as followings
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.broadcastreceivertesting"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.broadcastreceivertesting.MainActivity"
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="com.example.broadcastreceivertesting.PackageBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<data android:scheme="package" />
</intent-filter>
</receiver>
</application>
</manifest>
PackageBroadcastReceiver as a receiver are like following:
public class PackageBroadcastReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
final String action = intent.getAction();
if (Intent.ACTION_PACKAGE_REMOVED.equals(action))
{
File file = new File("/storage/sdcard0/zzz/yyy");
if (file.exists())
{
file.delete();
}
boolean createDir = new File("/storage/sdcard0/zzz/").mkdirs();
Log.d("XXX", "XXXX createDir=" + createDir);
try
{
file.createNewFile();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
}
Do I miss something ?
Try changing this...
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<data android:scheme="package" />
to this...
<intent-filter>
<action android:value="android.intent.action.PACKAGE_REMOVED" />
<scheme android:value="package" />

I think the broadcast receiver is not getting activated wile i am calling my phone.
How do you know your broadcast receiver is not working? Place a Log message inside onReceive() right at the beginning. It might be that your extras == null
But how to make my receiver functional now?
Check out example #5 and just follow the same steps.
Bro i dont think activity will get launched.
Well, it does: You are starting it in your onReceive():
Intent x = new Intent (c, EavesDropperActivity.class);
c.startActivity(x);
However, you are not setting any content in your Activity i.e no UI screen is presented because you have this line commented in onCreate() of EavesDropperActivity Activity:
//setContentView(R.layout.main);
So, you need to think hard on what you are trying to achieve in EavesDropperActivity
HTH.
Put this
<android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
in mainfest file for broadcast receiver.
Add your package name to your receiver class as,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp"
android:versionCode="1"
android:versionName="1.0" >

Really Appreciate the help. Thanks!!
you need to declare permission in your manifest
<permission
android:name="com.example.yamba.permission.REFRESH"
android:protectionLevel="signature"
/>
You need to declare this REFRESH Permission in the manifest as well.
here is an example code of how to declare a permission
<permission
android:name="A_PERMISSION"
android:description="#string/broadcast_permission_desc"
android:label="#string/broadcast_permission_label"
android:permissionGroup="#string/broadcast_permission_group"
android:protectionLevel="signature" />
