Error with reading parcelable object (after application is restored)

I have to save my custom class in save state bundle. So, I made it Parcelable and it looks good. When I rotate screen everything is goind well. But, when I minimalize my app, open some other, rotate screen and I try to go back to my app (from recent apps) it crashes.

So, players is parcelable class. It is basically a List. Player is another class, serializable.
Player.java
import java.io.Serializable;
public class Player implements Serializable{
private String name;
private int points = 0;
// getters and setters
}
Players.java
public class Players implements Parcelable {
private List<Player> players;
//constructor, getters, setters
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeList(players);
}
public static final Parcelable.Creator<Players> CREATOR = new Parcelable.Creator<Players>() {
public Players createFromParcel(Parcel in) {
return new Players(in);
}
public Players[] newArray(int size) {
return new Players[size];
}
};
public Players(Parcel in) {
in.readList(players, List.class.getClassLoader());
}
}
At this point I don't know why my app crash. When I rotate it it's ok, when I minimize and maximize is ok, when I minimize, do some staff (open another app, rotate screen etc) and try to maximize it from recents it crash.
I'll be very gratefull for any kind of help ;) !
Have a good afternoon!

Parcelable class nest parcelable objects only.
Here in your case Player is not parcelable and is used in Parcelable class Players. Try to implement Parcelable in Player class too.
Your problem with minimising and opening the application is because Parcelable object is saved but it is not retrieved properly.
try to make following changes in your code :
public class Player implements Parcelable{
String name;
int points;
// getter setter
public static final Creator<Player> CREATOR = new Parcelable.Creator<Player>() {
#Override
public Player createFromParcel(Parcel in) {
return new Player(in);
}
#Override
public Player[] newArray(int size) {
return new Player[size];
}
};
public Player(Parcel in) {
this.name = in.readString();
this.points = in.readInt();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(points);
}
}
And in Players class while reading the list replace:
in.readList(players, List.class.getClassLoader());
with :
players = new ArrayList<>();
in.readList(players, getClass().getClassLoader());
Your code should work fine after these changes.

Hi every one I have created a fragment class and included in my project.Now the problem is the classes which i have included fragment is not working and it get stops unfortunately.It shows error like this.

Watch out for this log message
Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class fragment
You are having some problem with the xml view file . and most probably in line no 11 . you can try removing
xmlns:ads="http://schemas.android.com/apk/res-auto"
from adview.The namespace is declared in the root element .Also the fill_parent is depreciated . use match_parent

I'm making an app that needs to login with facebook and then start maps. It crashes instantly on my phone with "has unfortunaly stopped working". It seems to be the facebook SDK widget button that I use for login, but I cant figure out how to fix it

My project is composed of two modules, test-kt and app, for the new Kotlin stuff and existing Java code respectively. test-kt/build.gradle has the following:
apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 9
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
main.kotlin.srcDirs += 'src/main/kotlin'
main.java.srcDirs += 'src/main/kotlin'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
}
buildscript {
ext.kotlin_version = '0.11.91.2'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.android.tools.build:gradle:1.1.0'
}
}
repositories {
mavenCentral()
}
I've tried adding the Kotlin libs as dependencies within app as well with no luck. Is there something I'm missing?
EDIT: Upon further investigation, it looks like this only happens whenever I use property references (such as ::x) and not when I use extension methods. I definitely have included kotlin-reflect... any ideas?

I just encountered this as well when upgrading to Kotlin version 0.11.91.2. There is apparently an issue where the Android toolset does not pack a file prepended with a dot into resources. (note that the file the exception references, .kotlin_string_table, is prepended with a dot).
A fix has been written but not yet released. You can try using the snapshot release of Kotlin in order to take advantage of it, or otherwise just wait for the next update.

fragments class unable to start activity componentinfo

I wanted to learn Fragment. So started to learning from tutorialspoint.com.
The Example was:
This example will explain you how to create your own Fragments. Here
we will create two fragments and one of them will be used when device
is in landscape mode and another fragment will be used in case of
portrait mode.
When I runned application occurred this Exception:

Why?????
I think this is may related to API level (My application API level is 21).
Please see example link and help. Thanks.

The tag fragment in your xml should be: Fragment, it uses
capital letters.

First, the name of fragment in activity_main.xml should be your fragment's absolute path.In this case, name should be net.motameni.apps.fragments.LM_Fragment
Second, in the line of fragmentTransaction.replace(android.R.id.content,pm_fragment);, R should be your-pkg-name.R but not android.R. The former is the R you generated while the latter is generated by Android SDK.
Third, if you want to add a pm_fragment, you need to change your activity_main.xml into this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:baselineAligned="false"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<FrameLayout
android:id="#+id/content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
Meanwhile, you need change your code like this:
fragmentTransaction.replace(R.id.content,pm_fragment);
Most importantly, the R is your-pkg-name.R

here in your fragment XML :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
you have to add a context to it and change it to :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.blaw.blawblaw">
then in your Main XMl :
<fragment
android:name="net.motameni.apps.fragments"
android:id="#+id/lm_fragment"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"/>
you don't have this fragment "net.motameni.apps.fragments" ! you should change it to "com.blaw.blawblaw" then that fragment show on your page !
and you just need one fragment in your XML , you add two , that's wrong
just add one and then handle fragment changing on your main class !
Best Regard !
