在操作安卓版本23+的文件读取时，不仅要在maniests中声明，还要在代码中动态声明：

private static final int REQUEST_EXTERNAL_STORAGE = 1; private static String[] PERMISSIONS_STORAGE = { Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}; /** * 8* Checks if the app has permission to write to device storage * 9* * 10* If the app does not has permission then the user will be prompted to * 11* grant permissions * 12* * 13* @param activity * 14 */ public static void verifyStoragePermissions(Activity activity) { // Check if we have write permission int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE); if (permission != PackageManager.PERMISSION_GRANTED) { // We don‘t have permission so prompt the user ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE); } }
