string - android error setting Drawable -

-

मेरे पास follwing कोड है 

  फ़ाइल f = नया फ़ाइल (temp); ड्रायनीय डी = ड्रायबल.क्रेडिटफॉम्पेथ (एफ.एटएबेसोल्यूटपाथ ()); background.setBackgroundDrawable (घ);

अस्थायी एक स्ट्रिंग है जिसमें एसडी कार्ड पर एक तस्वीर का पथ "/storage/emulated/0/Pictures/pic1.jpg" में होता है

कोई भी विचार यह कैसे तय है?

किसी भी मदद की सराहना की

मार्क

  & lt; उपयोग-अनुमति एंड्रॉइड: name = "android.permission.READ_EXTERNAL_STORAGE" / & gt;
