मैं एक ऐप विकसित कर रहा हूं जिसमें मुझे अपने ऐप को हर डिवाइस के लिए फिट करना है - टैबलेट और एंड्रॉइड मोबाइल दोनों के लिए। अब मैं रनटाइम पर डिवाइस की ऊंचाई और चौड़ाई प्राप्त करना चाहता हूं और इसे अपने कोड में कार्यान्वित करना चाहता हूं ताकि मेरा ऐप लैंडस्केप और पोर्ट्रेट दोनों के लिए काम करे।रनटाइम पर डिवाइस की ऊंचाई और चौड़ाई कैसे प्राप्त करें?
