我有一个现有的应用程序,我想实现Android 6.0的运行时权限.我在运行时权限上已经阅读了很多不同的东西,但我似乎无法绕过所有不同的片段.我找到的任何内容实际上都没有显示如何将其实现到现有的Activity中.

其他要点

当我运行针对SDK v23的现有应用程序时,我得到了预期的权限错误,但我得到的权限错误甚至不是我请求的权限.我在Manifest文件中有SEND_SMS权限,但我得到的错误是READ_SMS.我的应用程序在6.0之前运行正常,没有READ_SMS.

我希望我的应用程序在应用程序启动后立即请求许可,因为应用程序的唯一目的是发送短信,因此没有该权限,该应用程序没有其他用途.

问题：

一旦应用程序启动,我如何将SEND_SMS的运行时权限实现到我现有的Activity中？

这些权限的处理是否需要在后台线程中运行？

我是否还需要READ_SMS的权限,因为这是它给出的权限错误(即使该权限从未在我的应用程序上使用过)？

我现有的活动：

}

解决方法 AndroID 6.0的运行时权限模型主要分为部分

1.检查许可

2.申请许可

您可以在活动中为此项创建两种方法,如下所示

检查权限

private boolean checkPermission(){    int result = ContextCompat.checkSelfPermission(context,Manifest.permission.READ_SMS);    if (result == PackageManager.PERMISSION_GRANTED){        return true;    } else {        return false;    }}

请求许可

private voID requestPermission(){    if (ActivityCompat.shouldShowRequestPermissionRationale(activity,Manifest.permission.READ_SMS)){        Toast.makeText(context,"Read Sms Allowed.",Toast.LENGTH_LONG).show();    } else {        ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.READ_SMS},PERMISSION_REQUEST_CODE);    }}

最后但并非最不重要的是,您需要覆盖onRequestPermissionsResult方法

@OverrIDepublic voID onRequestPermissionsResult(int requestCode,String permissions[],int[] grantResults) {    switch (requestCode) {        case PERMISSION_REQUEST_CODE:            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                Snackbar.make(vIEw,"Permission Granted,Now you can access SMS.",Snackbar.LENGTH_LONG).show();            } else {                Snackbar.make(vIEw,"Permission DenIEd,You cannot access SMS.",Snackbar.LENGTH_LONG).show();            }            break;    }}

正如你所问我需要在线程中运行它.答案是否只是在主线程中执行此 *** 作
