兼容老版本的动态申请权限代码

//动态申请权限
private void initPermission() {
    if (Build.VERSION.SDK_INT >= 23 ) {

        String permissions[] = {
                Manifest.permission.INTERNET,
                Manifest.permission.CAMERA,
                Manifest.permission.READ_EXTERNAL_STORAGE,
                Manifest.permission.WRITE_EXTERNAL_STORAGE,
          };
        ArrayList<String> toApplyList = new ArrayList<String>();
        for (String perm : permissions) {
            if (PackageManager.PERMISSION_GRANTED != checkSelfPermission(perm)) {
                toApplyList.add(perm);
                //进入到这里代表没有权限.
            }
        }
        if(toApplyList.size()==0)
        {
            return;
        }
        else
        {
            requestPermissions(toApplyList.toArray(new String[toApplyList.size()]), 0);
        }
    }
}
