java - 无法获取设备 IMEI

Question

我想获取设备IMEI，但它总是显示日志:

E/GoogleTagManager: Invalid macro: _gtm.loadEventEnabled

我已经添加了以下内容

apply plugin: 'com.google.gms.google-services'在build.grade中

<uses-permission android:name="android.permission.READ_PHONE_STATE" />在 AndroidManifest.xml 中。

我该如何修复它？或者有什么办法获取设备IMEI吗？

这是我的代码:

public class MainActivity extends AppCompatActivity {

    public static String deviceIMEI;

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

        TelephonyManager TelephonyMgr = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        deviceIMEI = TelephonyMgr.getDeviceId();
        Log.e("MainActivity", "deviceIMEI: " + deviceIMEI);
    }

}

这是我的 AndroidManifest.xml:

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

        </service>

        <service

            </intent-filter>
        </service>
    </application>

</manifest>

Answer 1

首先，您必须在 list 文件中请求用户访问电话权限:-

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

此后您可以获得 IMEI 号码
