मैं कई दिनों से इस विषय पर एक गंभीर शोध कर रहा हूं ... मैंने यहां कई विषयों को भी देखा ... लेकिन दुर्भाग्य से मुझे कोई समाधान नहीं मिला ....एंड्रॉइड जियोफ़ेंस केवल खुले ऐप के साथ काम करता है
मैं एक ऐप्स geofence के लिए नया गूगल एपीआई का उपयोग करता है ... लिख रहा हूँ ठीक है, मैं "इन" और एक geofence की "बहिष्कार" संभाल कर सकते हैं, लेकिन केवल तभी मेरे ऐप खुला है! यहां तक कि अगर मैं वाईफाई, जीपीएस ऑन और 3 जी पर हूं, लेकिन ऐप, यह किसी भी घटना को ट्रिगर नहीं करता है ... बस अगर ऐप खुला है ...
मैं बिल्कुल उसी GeofenceRequester का उपयोग कर रहा हूं प्रलेखन की कक्षा http://developer.android.com/training/location/geofencing.html।

कोई भी मदद महान होगी! धन्यवाद!
हाय पोस्ट किया है, मैं डाउनलोड किया है और डेवलपर की वेबसाइट से geofence कोड भाग गया और यह मेरे लिए ठीक काम किया। ReceiveTransitionService क्लास को ऐप बंद होने के बावजूद भी कॉल किया जाता है और यह एक प्रसारण इन्टेंट है जिसे किसी भी मामले में निकाल दिया जा रहा है – Android2390
कोड मेरे लिए Google नमूना के साथ काम नहीं करता है और दूसरा उदाहरण है कि मेरे पास – benoffi7
@ b-ryce है यह कोड बेहद अत्यंत रहा है मेरे लिए उपयोगी, इसके लिए धन्यवाद! मैं सोच रहा था कि "MyAplication.getContext()" क्या था? क्या यह GeoFenceReciever.java या आपके लिए मुख्य खंड गतिविधि के लिए संदर्भ है? – Smoore
