如何解决“没有找到处理意图的活动”错误？ [英] How to solve 'no activity found to handle intent' error?

问题描述

我收到此错误：

I got this error :

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.APPLICATION_DETAILS_SETTINGS dat=Package:com.example.mjk.thefirst }

我用Kotlin写了这个，我试图在其他网站上做这个建议，但它没有用。 ..

I wrote this with Kotlin a I tried to do that suggestion in other websites,but It didn't work...

package com.example.mjk.thefirst

import android.content.Intent
import android.net.Uri
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.provider.ContactsContract
import android.provider.Settings
import kotlinx.android.synthetic.main.activity_intent.*

class IntentActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_intent)


        saveButton.setOnClickListener{

            addContact(name.text.toString(),phoneNumber.text.toString())

        }


        sendButton.setOnClickListener{

            sendMessage(msgEditText.text.toString())

        }


        setButton.setOnClickListener{

            openAppSetting()

        }

        callButton.setOnClickListener{

            phoneCall(phoneNumber.text.toString())

        }


    }



/*    private fun openSetting(){

        val intent = Intent(Settings.ACTION_WIFI_SETTINGS)
        startActivity(intent)

    }*/


    private fun phoneCall( PhoneNumber : String ){

        val i = Intent(Intent.ACTION_DIAL)
        i.data = Uri.parse("tel : $PhoneNumber")
        startActivity(i)

    }


    private fun addContact(Name : String,Number:String){

        val intent = Intent(Intent.ACTION_INSERT)
        intent.type = ContactsContract.Contacts.CONTENT_TYPE
        intent.putExtra(ContactsContract.Intents.Insert.NAME , Name)
        intent.putExtra(ContactsContract.Intents.Insert.PHONE , Number)
        startActivity(intent)

    }


    private fun sendMessage(Message : String){

        val intent = Intent(Intent.ACTION_SEND)
        intent.type = "text/plain"
        intent.putExtra(Intent.EXTRA_TEXT,Message)
        startActivity(intent)

    }


    private fun openAppSetting(){

        val intent = Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
        intent.data = Uri.fromParts("Package",packageName,null)
        startActivity(intent)

    }




}

此处显示：

And here is manifest :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.mjk.thefirst">

推荐答案

PhoneNumber）
startActivity（i）

}


private fun addContact（Name：String，Number：字符串）{

val intent = Intent（Intent.ACTION_INSERT）
intent.type = ContactsContract.Contacts.CONTENT_TYPE
intent.putExtra（ContactsContract.Intents.Insert.NAME，Name ）
intent.putExtra（ContactsContract.Intents.Insert.PHONE，Number）
startActivity（intent）

}


私人乐趣sendMessage（Message：String）{

val intent = Intent（Intent.ACTION_SEND）
intent.type =text / plain
intent.putExtra（Intent.EXTRA_TEXT，Message ）
startActivity（意图）

}


私人乐趣openAppSetting（）{

val intent =意图（设置） .ACTION_APPLICATION_DETAILS_SETTINGS）
intent.data = Uri.fromParts（Package，packageName，null）
startActivity（intent）

}




}

PhoneNumber") startActivity(i) } private fun addContact(Name : String,Number:String){ val intent = Intent(Intent.ACTION_INSERT) intent.type = ContactsContract.Contacts.CONTENT_TYPE intent.putExtra(ContactsContract.Intents.Insert.NAME , Name) intent.putExtra(ContactsContract.Intents.Insert.PHONE , Number) startActivity(intent) } private fun sendMessage(Message : String){ val intent = Intent(Intent.ACTION_SEND) intent.type = "text/plain" intent.putExtra(Intent.EXTRA_TEXT,Message) startActivity(intent) } private fun openAppSetting(){ val intent = Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS) intent.data = Uri.fromParts("Package",packageName,null) startActivity(intent) } }

这里有清单：
