this answer based on other answer in java. using androidjavaclass , androidjavaobject, won't need java code , jar/aar plugin at-all. done c#.

string[] getandroidemailaccounts() {     androidjavaclass unityplayer = new androidjavaclass("com.unity3d.player.unityplayer");     androidjavaobject currentactivity = unityplayer.getstatic<androidjavaobject>("currentactivity");      androidjavaclass acmanager = new androidjavaclass("android.accounts.accountmanager");     androidjavaobject acmanageract = acmanager.callstatic<androidjavaobject>("get", currentactivity);      androidjavaobject accounts = acmanageract.call<androidjavaobject>("getaccountsbytype", "com.google");     androidjavaobject[] accountarray = androidjnihelper.convertfromjniarray<androidjavaobject[]>(accounts.getrawobject());      string[] accountname = new string[accountarray.length];      (int = 0; < accountname.length; i++)     {         accountname[i] = accountarray[i].get<string>("name");     }      return accountname; }

you need permission in manifest:

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

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -
