Android: How to parse JSON file with GSON library?

Looking at your data it seems your identifiers are not constant. In this case it would work if you use a typemap. So something like this: HashMap<String, Integer> mMap = null; Type type = new TypeToken<HashMap<String, Integer>>() {}.getType(); mMap = new Gson().fromJson(json, type);

Create POJO for your json response. public class JsonResponsePojo { @SerializedName("KD Privat") @Expose private Integer KDPrivat; @SerializedName("KD WLAN Hotspot") @Expose private Integer KDWLANHotspot; @Expose private Integer treeWifi; @Expose private Integer cafeWifi; /** * * @return * The KDPrivat */ public Integer getKDPrivat() { return KDPrivat; } /** * * @param KDPrivat * The KD Privat */ public void setKDPrivat(Integer KDPrivat) { this.KDPrivat = KDPrivat; } /** * * @return * The KDWLANHotspot */ public Integer getKDWLANHotspot() { return KDWLANHotspot; } /** * * @param KDWLANHotspot * The KD WLAN Hotspot */ public void setKDWLANHotspot(Integer KDWLANHotspot) { this.KDWLANHotspot = KDWLANHotspot; } /** * * @return * The treeWifi */ public Integer getTreeWifi() { return treeWifi; } /** * * @param treeWifi * The treeWifi */ public void setTreeWifi(Integer treeWifi) { this.treeWifi = treeWifi; } /** * * @return * The cafeWifi */ public Integer getCafeWifi() { return cafeWifi; } /** * * @param cafeWifi * The cafeWifi */ public void setCafeWifi(Integer cafeWifi) { this.cafeWifi = cafeWifi; } } Read wifi -HotSpot Gson gson=new Gson(); JsonResponsePojo data=gson.fromJson(responseString, JsonResponsePojo.class); String kdWLanHotSpot=data.getKDPrivat();
