进程已列入白名单-从Firebase接收数据时应用崩溃

Question

从Firebase接收数据时，我面临一个很大的问题。 我想要一种方法来接收目标，而其他方法来接收用户位置。

这是我的代码：

private DatabaseReference mDatabase,mDatabase2;
LocationHelper locationHelpry;

protected void onCreate(Bundle savedInstanceState) {

    mDatabase = FirebaseDatabase.getInstance().getReference().child("users");
    mDatabase2 = FirebaseDatabase.getInstance().getReference("users").child("targets");

    ReceiveTargets();
    RecieveLocation();

}

private void ReceiveTargets(){
    Log.i("ttt","1st created");

    mDatabase2.addValueEventListener(new ValueEventListener() {

        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            Log.i("ttt","2nd Created");
            for (DataSnapshot ds: dataSnapshot.getChildren()){
                LocationHelper locationHelper = new LocationHelper();
                locationHelper = ds.getValue(LocationHelper.class);

                Log.i("ttt", "rrr"+ds.getChildrenCount());
            }
        }
    }
}

错误正在显示：

E/Zygote: isWhitelistProcess - Process is Whitelisted
