As you know this is how we fire a JobIntentService
:
JobIntentService.enqueueWork(this,
MyJobIntentService.class,
JOB_ID,
intent);
In this approach we KNOW which service we want to start and pass its class to the method.
Here is my question: Is there any way to start a service implicitly ?
Why I need this ? I'm developing a library that sometimes should start a service that developer extends and obviously I have no access to it from library
What I tried? I implemented it with IntentService
(using intent filters) and worked fine for pre O devices but for Android Oreo I'm receiving this crash log:
Fatal Exception: java.lang.IllegalStateException: Not allowed to start
service Intent { act=someAction
pkg=somePackage (has extras) }: app is in background uid
UidRecord{de24eda u0a238 RCVR idle procs:1 seq(0,0,0)}
So I moved to JobIntentService
, now the problem is that I can't start it implicitly.
Any solution or alternative will be appreciated.
Well, I found a solution, first query for service you're looking for and check if has the necessary permission for JobIntentService
, then enqueue work :
private final String PERMISSION_BIND_JOB_SERVICE = "android.permission.BIND_JOB_SERVICE";
Intent handlerIntent = new Intent(MY_ACTION);
List<ResolveInfo> result =
getPackageManager().queryIntentServices(handlerIntent, 0);
if (result.size() > 0) {
ResolveInfo info = result.get(0);
if (info != null && info.serviceInfo != null &&
info.serviceInfo.permission != null){
String permission = info.serviceInfo.permission;
if (permission.equals(PERMISSION_BIND_JOB_SERVICE)) {
try {
Class<?> serviceClass = Class.forName(info.serviceInfo.name);
JobIntentService.enqueueWork(this,
serviceClass,
JOB_ID, handlerIntent);
} catch (ClassNotFoundException e) {
//Handle exception if you will
}
}
}
}
And in app module manifest I added android.permission.BIND_JOB_SERVICE
to my service as well:
<service
android:name=".MyService"
android:enabled="true"
android:permission="android.permission.BIND_JOB_SERVICE"
android:exported="false">
<intent-filter>
<action android:name="MY_ACTION" />
</intent-filter>
</service>
