用TelephonyManager获取峨眉

Question

我正在尝试获取dispositvo的峨眉标识号，我尝试过这个方法，但我总是返回null：

代码：

private String getEmei()
    {
        String Emei="";
        try
        {
            TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
            Emei=telephonyManager.getDeviceId();
        }

        catch(Exception ex)
        {
            return "";
        }

        if (Emei==null)
        {
            return "";
        }

        Long suma_digitos =Long.valueOf(Emei);

        if (suma_digitos==0) 
            return "";
        else
        {
            //Log.i("Emei","emei: "+Emei+"\n");
            return Emei;
        }
    }

如果您必须对文件或manifiest.xml (这是解决方案)设置一些权限，则不会。

我不在乎IMEI或其他唯一的设备编号。

非常感谢你尽力帮助你的时间。

试试下面的代码：

Main.java

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.widget.TextView;

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //Getting the Object of TelephonyManager 
        TelephonyManager tManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
        //Getting the SIM card ID
        String simId=tManager.getSimSerialNumber();

        //Getting Phone Number
        String tnumber=tManager.getLine1Number();

        //Getting IMEI Number of Devide
        String Imei=tManager.getDeviceId();

        TextView s=(TextView)findViewById(R.id.simid);//Getting TexView from main.xml to Display SIM Card Id
        s.setText("Sim id - "+simId);//Displaying SIM card Id in the TextView
        TextView t=(TextView)findViewById(R.id.phoneno);//getting TextView from main.xml to display Phone Number
        t.setText("Phone No - "+tnumber);//Displaying the Phone Number.
        TextView i=(TextView)findViewById(R.id.imeino);//Getting the TextView to display IMEI number
        t.setText("IMEI number - "+Imei);//Displaying IMEI number



    }
}

布局XML代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Phone Detail"
        android:textAppearance="?android:attr/textAppearanceLarge" />

<!-- TextView to display SIM Card id -->
    <TextView
        android:id="@+id/simid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium" />

<!-- TextView to Display IMEI no -->
    <TextView
        android:id="@+id/imeino"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium" />

<!-- TextView to Display Phone Number -->
    <TextView
        android:id="@+id/phoneno"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>

与您的

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.imei"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />
    <!-- Permission to Read Phone Detail such as IMEI no,SIM Card Id etc -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".Main" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
