java - Telephonymanager.EXTRA_INCOMING_NUMBER 在 API 级别 29 中已弃用

Question

我需要在 Android 中识别来电电话号码，但使用 TelephonyManager.EXTRA_INCOMING_NUMBER android studio 警告 EXTRA_INCOMING_NUMBER 已弃用。我通过了开发人员.android.com，它显示执行调用筛选的应用应使用 CallScreeningService API。但我不知道如何使用 CallScreeningService 来获取来电电话号码。谁能帮帮我？

正如@Saurabh 所说，筛选调用的新方法是通过CallScreeningService。但是，要在 Android Q 及更高版本上运行该服务，用户需要将您的应用设置为默认来电显示和垃圾邮件应用(通过使用新的 RoleManager 类完成)

1. 注册您的筛查服务:

    <service android:name="com.example.ScreeningService"
        android:permission="android.permission.BIND_SCREENING_SERVICE">
        <intent-filter>
            <action android:name="android.telecom.CallScreeningService"/>
        </intent-filter>
    </service>
   

2. 创建你的服务类:

    @RequiresApi(api = Build.VERSION_CODES.N)
    class ScreeningService : CallScreeningService() {
   
        override fun onScreenCall(details: Details) {
            //code here
        }
   
    }
   

3. 在您的主要 Activity (或您认为合适的任何地方)中向用户请求筛选角色:

    @RequiresApi(Build.VERSION_CODES.Q)
    private fun requestScreeningRole(){
        val roleManager = getSystemService(Context.ROLE_SERVICE) as RoleManager
        val isHeld = roleManager.isRoleHeld(RoleManager.ROLE_CALL_SCREENING)
        if(!isHeld){
            //ask the user to set your app as the default screening app
            val intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_SCREENING)
            startActivityForResult(intent, 123)
        } else {
            //you are already the default screening app!
        }
    }
   

4. 捕捉用户的 react :

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
            super.onActivityResult(requestCode, resultCode, data)
            when (requestCode) {
                123 -> {
                    if (resultCode == Activity.RESULT_OK) {
                        //The user set you as the default screening app!
                    } else {
                        //the user didn't set you as the default screening app...
                    }
                }
                else -> {}
            }
        }
