Android的 - 致命異常：主要了java.lang.RuntimeException：無法啓動活動ComponentInfo

我試圖讓我的設備的電話號碼，收到以下錯誤：Android的 - 致命異常：主要了java.lang.RuntimeException：無法啓動活動ComponentInfo

致命異常：

主

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.dell.myapplication/com.example.dell.myapplication.MainActivity}: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10035 nor current process has android.permission.READ_PHONE_STATE.

我是一個新的android開發。我查看了LogCat生成的錯誤，但根據收到的錯誤不知道問題以及在哪裏找到它。

感謝您的幫助和抱歉的持續時間！

這裏是我的代碼：

MainActivity.java

package com.example.dell.myapplication; 

import android.content.Context;

import android.view.View; 
import android.widget.Button; 
import android.widget.Toast; 

import java.util.List; 

public class MainActivity extends ActionBarActivity { 

    public MainActivity() { 
    } 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     TelephonyManager tm=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE); 
     String imei = tm.getDeviceId(); 
     String phone = tm.getLine1Number(); 
     Toast.makeText(MainActivity.this, "my IMEI: "+imei, Toast.LENGTH_LONG).show(); 
     Toast.makeText(MainActivity.this,"my phone: "+phone,Toast.LENGTH_LONG).show(); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
//  if (id == R.id.action_settings) { 
//   return true; 
//  } 

     return super.onOptionsItemSelected(item); 
    } 
}

activity_main.xml中

您是否在清單中添加權限？ –

清單檔案中的添加READ_PHONE_STATE許可

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

READ_PHONE_STATE

Allows read only access to phone state.

Note: If both your minSdkVersion and targetSdkVersion values are set to 3 or lower, the system implicitly grants your app this permission. If you don't need this permission, be sure your targetSdkVersion is 4 or higher.

Protection level: dangerous Constant Value: "android.permission.READ_PHONE_STATE"

添加權限READ_PHONE_STATE

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

在你的清單，你需要爲了增加followong讀取手機號碼：

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

在你的logcat，系統講述了在你的理由此線錯誤：

Caused by: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10035 nor current process has android.permission.READ_PHONE_STATE.
