在android7.0的系统下发现TelephonyManager.getDeviceId()在权限允许的情况下取得返回值也为null,解决方法如下:
public static String getDeviceId(Context context) {
String id; //android.telephony.TelephonyManager TelephonyManager mTelephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); if (mTelephony.getDeviceId() != null) { id = mTelephony.getDeviceId(); } else { //android.provider.Settings; id = Settings.Secure.getString(context.getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID); } return id; }
