मेरे पास इस फ़ाइल में मेमोरी रिसाव है, मुझे बिल्कुल सही नहीं मिल रहा है, लेकिन मुझे लगता है कि यह छवि है ->(Bitmap bm = BitmapFactory.decodeFile(filename)), मैंने कई अलग-अलग प्रयास किए हैं तरीकों से लेकिन मैं इसे काम नहीं कर सकता।PHP सर्वर पर छवि के साथ एक फॉर्म भेजने की कोशिश करते समय एंड्रॉइड में मेमोरी लीक

अच्छा, छवियां कितनी बड़ी हो सकती हैं? यदि आप 5 मेगापिक्सेल फोटो लोड करते हैं, और उसके बाद पुराने को एक मेमोरी में रखते हुए इसे 1k * 1k तक आकार दें, तो आप केवल एक ही छवि द्वारा 24 एमबी के साथ समाप्त हो सकते हैं। – Jave

आपकी पोस्ट पर बहुत सारे कोड हैं, क्या आप इसे सबसे प्रासंगिक में कम कर सकते हैं, या अप्रासंगिक कोड को हटाने पर विचार कर सकते हैं। – Siddharth
