如何在Android中获取默认手机IMEI？

此示例演示了如何在android中获取默认手机IMEI。

步骤1-在Android Studio中创建一个新项目，转到File⇒New Project并填写所有必需的详细信息以创建一个新项目。

步骤2-将以下代码添加到res / layout / activity_main.xml。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:gravity="center"
   android:layout_height="match_parent"
   tools:context=".MainActivity"
   android:orientation="vertical">
   <TextView
      android:id="@+id/text"
      android:textSize="30sp"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />
</LinearLayout>

在上面的代码中，我们采用了文本视图来显示电话IMEI。

步骤3-将以下代码添加到java / MainActivity.xml

package com.example.myapplication;

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.RequiresApi;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.telephony.TelephonyManager;
import android.widget.TextView;

import static android.Manifest.permission.READ_PHONE_NUMBERS;
import static android.Manifest.permission.READ_PHONE_STATE;
import static android.Manifest.permission.READ_SMS;

public class MainActivity extends AppCompatActivity {
   private static final int PERMISSION_REQUEST_CODE = 100;
   TextView textView;
   TelephonyManager telephonyManager;

   @RequiresApi(api = Build.VERSION_CODES.P)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView = findViewById(R.id.text);
      telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
      if (ActivityCompat.checkSelfPermission(this, READ_SMS) != PackageManager.PERMISSION_GRANTED &&
         ActivityCompat.checkSelfPermission(this, READ_PHONE_NUMBERS) !=
         PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
         READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
         ActivityCompat.requestPermissions(this, new String[]{READ_SMS, READ_PHONE_NUMBERS, READ_PHONE_STATE}, PERMISSION_REQUEST_CODE);
      } else {
         textView.setText(""+telephonyManager.getImei());
      }
   }

   @RequiresApi(api = Build.VERSION_CODES.P)
   @Override
   public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
      super.onRequestPermissionsResult(requestCode, permissions, grantResults);
      switch (requestCode) {
         case PERMISSION_REQUEST_CODE:
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) != 
               PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
               Manifest.permission.READ_PHONE_NUMBERS) != PackageManager.PERMISSION_GRANTED &&
               ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) !=
               PackageManager.PERMISSION_GRANTED) {
               return;
            } else {
               textView.setText(""+telephonyManager.getImei());
            }
      }
   }
}

步骤3-将以下代码添加到AndroidManifest.xml

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

   <uses-permission android:name="android.permission.READ_PHONE_NUMBERS" />
   <uses-permission android:name="android.permission.READ_PHONE_STATE" />
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>
