在这里，我在ANDROID_DEVICE_ID = mTelephonyMgr.getDeviceId();线得到错误。

而我正在使用API 23进行测试。在我的其他应用程序中，此代码完美适用于API 23.

请包含相关的logcat消息。 –

你的'targetSdkVersion'是什么？你在测试什么版本的Android？ – CommonsWare

另外，您的清单结构可能有问题。请张贴整个清单，而不仅仅是行。如果您不在''标签外部放置这些标签，它们将被忽略。 –

如果您的设备是Android 6.0 Marshmallow，请确保您的targetSdkVersion小于23或使用以下代码来确定您是否已被授予READ_PHONE_STATE权限。

private void checkPermission() { 
    // Here, thisActivity is the current activity 
    if (ContextCompat.checkSelfPermission(thisActivity, 
        Manifest.permission.READ_PHONE_STATE) 
      != PackageManager.PERMISSION_GRANTED) { 

     // Should we show an explanation? 
     if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, 
       Manifest.permission.READ_PHONE_STATE)) { 

      // Show an explanation to the user *asynchronously* -- don't block 
      // this thread waiting for the user's response! After the user 
      // sees the explanation, try again to request the permission. 

     } else { 

      // No explanation needed, we can request the permission. 

      ActivityCompat.requestPermissions(thisActivity, 
        new String[]{Manifest.permission.READ_PHONE_STATE}, 
        MY_PERMISSIONS_REQUEST_READ_PHONE_STATE); 

      // MY_PERMISSIONS_REQUEST_READ_PHONE_STATE is an 
      // app-defined int constant. The callback method gets the 
      // result of the request. 
     } 
    } 
} 

@Override 
public void onRequestPermissionsResult(int requestCode, 
     String permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: { 
      // If request is cancelled, the result arrays are empty. 
      if (grantResults.length > 0 
       && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

       // permission was granted, yay! Do the 
       // contacts-related task you need to do. 

      } else { 

       // permission denied, boo! Disable the 
       // functionality that depends on this permission. 
      } 
      return; 
     } 

     // other 'case' lines to check for other 
     // permissions this app might request 
    } 
}

什么是MY_PERMISSIONS_REQUEST_READ_PHONE_STATE在这里？ –

@chiragpatel MY_PERMISSIONS_REQUEST_READ_PHONE_STATE是一个应用程序定义的int常量。它特定的请求代码与报告给onRequestPermissionsResult（int，String []，int []）的结果相匹配。 – Chaos

谢谢。但我收到未定义的错误MY_PERMISSIONS_REQUEST_READ_PHONE_STATE。！ –
