Change package name doesn't make changes in generated file

Change package name doesn't make changes in generated file - android

My package name was com.softmills.ogram and i have changed to com.ogram.sp and change applicationId in gradle file as well and clean the project and invalidate cash and restart it showed that error

this line that caused the problem import com.softmills.ogram.common.model.Shift;
i don't know why it still see the old package name so i change it manually and rerun again but the same issue cause it's generated class

FragmentStatePagerAdapter not refreshing fragments when notifyDataSetChanged is called

I am trying to implement a dynamic list update to FragmentStatePagerAdapter. I have a list of few fragments which have radio buttons, edit text, and different other fragments having just a single view.
Now the logic revolves around radio button fragment, so lets suppose you have a list having 10 elements and the list item showing the radio button is 6, and there are 2 options for the user to select on the radio button fragment. If user selects 1st option then 8th item should be shown and 7th should be skipped and if 2nd option is selected then 7th should be shown and then 9th.
I have added a view pager, and have an associated FragmentStatePagerAdapter associated with it. Now I was able to populate the list based on the option but when I refresh list in the adapter, it does not hops from 6th to 8th and still shows 7th.
Can someone help me around it on how can I implement the hopping mechanism on FragmentStatePagerAdapter?

I think the below line contains error
GlobalData.citydata = (PCityData) gson.fromJson(response.getString("data"), listType);
I think you are trying to cast gson.fromJson(response.getString("data"), listType) to PCityData which is ArrayList

you are getting error on this line:
GlobalData.citydata = (PCityData) gson.fromJson(response.getString("data"), listType);
because:
gson.fromJson(response.getString("data"), listType);
this return a arraylist and it is not casting into your custom model
to fix this change your GlobalData.java class
public static PCityData citydata = null;
to
public static ArrayList<PCityData> citydata = null;

Gson gson = new Gson();
Type listType = new TypeToken<List<PCityData>>() {
}.getType();
// Issue is here
GlobalData.citydata = (PCityData) gson.fromJson(response.getString("data"), listType);
Fix 1 : GlobalData.citydata should be of type List<PCityData>.
Fix 2 : Change like this GlobalData.citydata = (List<PCityData>) gson.fromJson(response.getString("data"), listType);

Clear Cache of All Apps in Marshmallow?

I try to solve using below code:
[Reference: Android: Clear Cache of All Apps?
PackageManager pm = getPackageManager();
// Get all methods on the PackageManager
Method[] methods = pm.getClass().getDeclaredMethods();
for (Method m : methods) {
if (m.getName().equals("freeStorage")) {
// Found the method I want to use
try {
long desiredFreeStorage = 8 * 1024 * 1024 * 1024; // Request for 8GB of free space
m.invoke(pm, desiredFreeStorage , null);
} catch (Exception e) {
// Method invocation failed. Could be a permission problem
}
break;
}
}
and add permission in AndroidMenifest.xml file
<uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>
But when i run this code, then throw exception :
java.lang.IllegalArgumentException: Wrong number of arguments; expected 3, got 2
Any suggestion to overcome this exception or another solution for clear cache of all apps programmatically. Thanks

follow the link. hopefully get a solutions

It looks like there is an additional freeStorage() method added in Android 6 (Marshmallow) that takes an additional volumeUuid parameter:
public void freeStorage(long freeStorageSize, IntentSender pi)
public abstract void freeStorage(String volumeUuid, long freeStorageSize,
IntentSender pi)
Obviously, the new method is showing up first in the returned list of declared methods.
To get around this, you can alter the orginal code so that it looks like this:
PackageManager pm = getPackageManager();
// Get all methods on the PackageManager
Method[] methods = pm.getClass().getDeclaredMethods();
for (Method m : methods) {
if (m.getName().equals("freeStorage")) {
Class[] params = m.getParameterTypes();
if (params.length == 2) {
// Found the method I want to use
try {
long desiredFreeStorage = 8 * 1024 * 1024 * 1024; // Request for 8GB of free space
m.invoke(pm, desiredFreeStorage , null);
} catch (Exception e) {
// Method invocation failed. Could be a permission problem
}
break;
}
}
}

How to pass List of list of objects from one activity to another

I need to pass an arraylist which contains object with a string and arraylist. I am unable to pass the arraylist to other activity. In the Activity1 the list contains value that I have verified.
DepositBn:
package support;
import android.os.Parcel;
import android.os.Parcelable;
import com.google.gson.annotations.SerializedName;
import java.util.ArrayList;
public class DepositBn implements Parcelable {
private String limit;
#SerializedName("period")
private ArrayList<Rate> rateList;
protected DepositBn(Parcel in) {
limit = in.readString();
}
public String getLimit() {
return limit;
}
public void setLimit(String limit) {
this.limit = limit;
}
public ArrayList<Rate> getRateList() {
return rateList;
}
public void setRateList(ArrayList<Rate> rateList) {
this.rateList = rateList;
}
public class Rate {
private String rate;
public String getRate() {
return rate;
}
public void setRate(String rate) {
this.rate = rate;
}
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(limit);
}
public static final Creator<DepositBn> CREATOR = new Creator<DepositBn>() {
#Override
public DepositBn createFromParcel(Parcel in) {
return new DepositBn(in);
}
#Override
public DepositBn[] newArray(int size) {
return new DepositBn[size];
}
};
}
In the Activity1:
#Override
protected void onPostExecute(ArrayList<DepositBn> result) {
super.onPostExecute(result);
System.out.println("result = " + result);
for (DepositBn depositBn : result) {
System.out.println("----" + depositBn.getLimit());
}
try {
Intent intent = new Intent(DepositRates.this, GenericRateDisplay.class);
Resources res = DepositRates.this.getResources();
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("depositBnArrayList",result);
bundle.putString("pageName", res.getString(R.string.domesticRates));
intent.putExtras(bundle);
startActivity(intent);
} catch (Exception ex) {
ex.printStackTrace();
}
}
In Activity2:
package in.co.sbm.sbmvirtual;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;
import support.DepositBn;
public class GenericRateDisplay extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_generic_rate_display);
Bundle b = this.getIntent().getExtras();
ArrayList<DepositBn> depositBnArrayList = b.getParcelableArrayList("depositBnArrayList");
//String pageName = b.getString("pageName");
ArrayList<String> rateList = new ArrayList();
for (DepositBn depositBn : depositBnArrayList) {
for(DepositBn.Rate rate : depositBn.getRateList()){
rateList.add(rate.toString());
}
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(GenericRateDisplay.this,
android.R.layout.simple_list_item_1, rateList);
ListView listView = (ListView) findViewById(R.id.genericListView);
listView.setAdapter(adapter);
}
}

I have fixed it. I have used inner class as well which I did not serialize hence I was unable to use putSerializable. I have serialized both the outer and inner class and used intent.putSerializable.

Loading data from sqlite and displaying on ViewPager

Been trying to load data from sqlite and display it on viewpager without much success.
I have a viewpager with two tabs which should hold data based on the tag_id passed as a parameter of newInstance. There is also an action bar navigation spinner with a list of counties that is used for filter data displayed based on the county_id.
Am able to fetch data from server and save it in the sqlite db but displaying it is the problem. Data is not dispalyed on the first page of the viewpager but it exists in the sqlite. Data for the second is the only one laoded.
