在Android M中实现新权限[重复]

Question

我正试图将以KitKat为目标版本开发的应用程序迁移到Nougat。我想实现新的权限特性。我的应用程序几乎不需要预先授予危险的权限（在安装时）。我该怎么做？将应用程序放在priv-app文件夹中就可以了吗？

Answer 1

String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};

    if(!hasPermissions(this, PERMISSIONS)){
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }



public static boolean hasPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}
