android-ANDROID 讀取系統圖片失敗

ANDROID 讀取系統圖片失敗

我是先獲取了系統圖庫裡的某個圖片的路徑 path，然後
File file = new File(path);
InputStream is = new FileInputStream(file);
然後就報錯W/System.err: java.io.FileNotFoundException: /storage/emulated/0/Tencent/QQ_Images/null-52a51a941f2792db.jpg: open failed: EACCES (Permission denied)

最佳回答：

你的tagetsdk大於等於23嗎？如果是的話，需要動態申請權限，在manifest裡申請是不行的
