如何使用代碼編程獲取設備的IMEI / ESN號但是在android> 6中

Question

我的Android版本是Marshmallow 6.0

如何以編程方式在android> 6中查找/獲取imei編號。

注意：我在AndroidManifest.xml文件中添加了READ_PHONE_STATE權限。

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

並且在MainActivity中

TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String deviceid = manager.getDeviceId();

//Device Id is IMEI number

Log.d("msg", "Device id " + deviceid);

我的Android版本是Marshmallow 6.0

注意：您需要運行時權限

我在AndroidManifest.xml文件中添加了READ_PHONE_STATE權限。

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

在MainActivity中：

private static final int PERMISSIONS_REQUEST_READ_PHONE_STATE = 999;

private TelephonyManager mTelephonyManager;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE},
                PERMISSIONS_REQUEST_READ_PHONE_STATE);
    } else {
        getDeviceImei();
    }
....

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {
    if (requestCode == PERMISSIONS_REQUEST_READ_PHONE_STATE
            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        getDeviceImei();
    }
}

private void getDeviceImei() {

    mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    String deviceid = mTelephonyManager.getDeviceId();
    Log.d("msg", "DeviceImei " + deviceid);
}

此外，在API級別26中不推薦使用getDeviceId（）方法。因此，您還需要使用getImei（）或getAllCellInfo（）來獲取imei詳細信息。

需要權限：READ_PHONE_STATE

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

/**
 * Gets the device unique id called IMEI. Sometimes, this returns 00000000000000000 for the
 * rooted devices.
 **/
public static String getDeviceImei(Context ctx) {
    TelephonyManager telephonyManager = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
    Log.i(Tag, "Return Sim count in device : "+manager.getPhoneCount());
    Log.i(Tag, "Defualt device ID: "+manager.getDeviceId());
    Log.i(Tag, "First Sim IMEI:  "+manager.getDeviceId(0));
    Log.i(Tag, "Secand Sim IMEI "+manager.getDeviceId(1));
    return telephonyManager.getDeviceId();
}

如果設備ID不可用，則返回null。
