android6.0权限问题

1、权限检测：checkSelfPermission(Manifest.permission.CAMERA)
　　权限申请：ActivityCompat.requestPermissions

if (Build.VERSION.SDK_INT >= 23) {
    if (checkSelfPermission(Manifest.permission.CAMERA)== PackageManager.PERMISSION_GRANTED){
　　　　//是否授权

　　 }else{
　　　　　ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA},101);

 　　}
}
2.权限“不再提示”

@Override
public void onRequestPermissionsResult(int requestCode,String[] permissions,int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    boolean hasAllGranted = true;
    for (int i = 0; i < grantResults.length; ++i) {
        if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
            hasAllGranted = false;
            if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permissions[i])) {
                //解释原因，并且引导用户至设置页手动授权
                Toast.makeText(this,"不在提示",Toast.LENGTH_SHORT).show();
                LogUtil.d("不再提示");
            } else {
                //权限请求失败，但未选中“不再提示”选项
                LogUtil.e("禁止权限");
            }
            break;
        }
    }
    if (hasAllGranted) {
        //权限请求成功
        Toast.makeText(this,"成功",Toast.LENGTH_SHORT).show();
        LogUtil.d("成功");
    }
}
