Question

I am building an android app for which I need to check the sync setting of each individual account registered in the device. I know that I can do it through ContentResolver class but I am having some problem with it. I’ve managed to get the list of all accounts on the device but I don’t know where to get the relevant authority of a specific account at run time. Below is the code:

AccountManager acm = AccountManager.get(getApplicationContext());
    Account[] acct = acm.getAccounts();
    for(int i=0;i<acct.length;i++){
        int p = ContentResolver.getIsSyncable(acct[i], null);
        Log.i(TAG,"account name is"+acct[i].name);
        Log.i(TAG,"answer to syncable is: "+String.valueOf(p));

The getIsSyncable(Account am,String authority) asks for an account and an authority. As you can see I am passing in NULL instead of the actual authority. Does anyone know of a way I can find the authority to the relevant account?

You can retrieve the known SyncAdapters and then query the ContentResolver

AccountManager acm
        = AccountManager.get(getApplicationContext());
    Account[] acct = null;

    SyncAdapterType[] types = ContentResolver.getSyncAdapterTypes();
    for (SyncAdapterType type : types) {
      Log.d(TAG, "--------------------");
      Log.d(TAG, type.authority + "--" + type.accountType);
      acct = acm.getAccountsByType(type.accountType);
      for (int i = 0; i < acct.length; i++) {
        int p = ContentResolver.getIsSyncable(acct[i], type.authority);
        Log.i(TAG, "account name: " + acct[i].name);
        Log.i(TAG, "syncable: " + String.valueOf(p));
      }
    }

Output:
