Start IntentService from other App - android-intentservice

Question

I´m trying to start a IntentService from other App, now I have an Activity with an AsyncTask where I download a file. This works fine but I want download the file in a IntentService and don´t have to show the activity, just a Notification. Is this possible? I have read that IntentService starts when a Activity calls it through startService(Intent), but when I try nothing happens :(
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bajar);
intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if(Intent.ACTION_SEND.equals(action) && type != null){
if("text/plain".equals(type)){
String todo = intent.getStringExtra(Intent.EXTRA_TEXT);
if(todo != null){
id = new Descarga(todo);
EditText textNombre = (EditText) findViewById(R.id.TextNombre);
textNombre.setText(id.nombre);
/*
This works
d = new Download();
d.execute();
/*
startService(intent); //This don´t work
}
}
}
}
This is the Activity xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="es.esy.palmaseca.descargayt.Bajar">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/nombre"
android:id="#+id/txtNombre"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_gravity="center" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/TextNombre"
android:layout_below="#+id/txtNombre"
android:layout_centerHorizontal="true"
android:editable="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0"
android:id="#+id/txtActual"
android:layout_marginTop="44dp"
android:layout_below="#+id/TextNombre"
android:layout_centerHorizontal="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0"
android:id="#+id/txtFinal"
android:layout_below="#+id/txtActual"
android:layout_centerHorizontal="true"
android:layout_marginTop="35dp" />
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/barra"
android:layout_below="#+id/txtFinal"
android:layout_centerHorizontal="true"
android:layout_marginTop="55dp" />
My Class IntentService:
public class Descargar extends IntentService {
NotificationManager nm;
Notification notification;
static String ns = Context.NOTIFICATION_SERVICE;
int icono = R.drawable.icono;
public Descargar() {
super("Descargar");
Log.d("Serivicio", "Star");
}
#Override
protected void onHandleIntent(Intent intent) {
String action = intent.getAction();
String type = intent.getType();
if(Intent.ACTION_SEND.equals(action) && type != null){
if("text/plain".equals(type)){
String todo = intent.getStringExtra(Intent.EXTRA_TEXT);
if(todo != null){
Descarga d = new Descarga(todo);
bajar(d);
}
}
}
}
The function bajar is the same as Download AsynTask.
And finally the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="es.esy.palmaseca.descarga" >
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<application
android:allowBackup="true"
android:icon="#drawable/icono"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".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>
<service
android:enabled="true"
android:name=".Descargar"
android:exported="true" >
</service>
<activity
android:name=".Bajar"
android:label="#string/bajar" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
</application>
I have tried to start the IntentService but I can´t find out where is the mistake, and throws 0 errors
Sorry my english 🙏

An easy solution is to create a BroadcastReceiver, register it in your manifest for some intent action and then have it start the intentservice.
public class Descargar extends IntentService {
NotificationManager nm;
Notification notification;
static String ns = Context.NOTIFICATION_SERVICE;
int icono = R.drawable.icono;
public static class DescargarReceiver implements BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(), Descargar.class.getName());
context.startService(intent.setComponent(comp));
}
}
public Descargar() {
super("Descargar");
Log.d("Serivicio", "Star");
}
#Override
protected void onHandleIntent(Intent intent) {
String action = intent.getAction();
String type = intent.getType();
if(Intent.ACTION_SEND.equals(action) && type != null){
if("text/plain".equals(type)){
String todo = intent.getStringExtra(Intent.EXTRA_TEXT);
if(todo != null){
Descarga d = new Descarga(todo);
bajar(d);
}
}
}
}
and in the manifest:
<receiver
android:name=".Descargar$DescargarReceiver"
android:exported="true>
<intent-filter>
<action
android:name="com.mycompany.action.START_DESCARGAR_SERVICE" />
</intent-filter>
</receiver>
<service
android:enabled="true"
android:name=".Descargar"
android:exported="true" >
</service>
and then you can just broadcast the intent from any app:
Intent intent = new Intent("com.mycompany.action.START_DESCARGAR_SERVICE");
intent.putExtra(.....)
sendBroadcast(intent);
