I'm creating my own application. I tested it on Android Lollipop and Marshmallow - everything works great. But whenever I try Android Kitkat, an error occurs. Here's error log:
E/AndroidRuntime: FATAL EXCEPTION: main

It looks like problem is on line 62 in "progi" class, but - as for me - everything is OK especially that on newer Android versions it works great.
public class Progi extends AppCompatActivity {
Intent intent;
Bundle liczby;
Bundle doble;
BigDecimal tablica [][];
BigDecimal punkty = new BigDecimal(-1);
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
android.content.SharedPreferences shared = android.preference.PreferenceManager.getDefaultSharedPreferences(this);
boolean warunek = shared.getBoolean("serial", false);
android.view.MenuItem menuitem = menu.getItem(0);
if(warunek)
{
menuitem.setTitle("Oceny pojedynczo");
}
else menuitem.setTitle("Oceny seryjnie");
return true;
}
public boolean onCreateOptionsMenu(Menu menu) {
android.view.MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.firstmenu, menu);
return true;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layoutprogi);
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
getSupportActionBar().setTitle("Progi punktowe");
intent = getIntent();
liczby = intent.getBundleExtra("liczby");
doble = intent.getBundleExtra("doble");
tablica = (BigDecimal[][]) doble.getSerializable("doble"); //here is line 62
if(intent.hasExtra("max")) {
Bundle a = intent.getBundleExtra("max");
punkty = (BigDecimal) a.getSerializable("max");
}
przejscie(true);
if(punkty.compareTo(new BigDecimal(-3))==0)
{
procenty(findViewById(android.R.id.content));
}
else if(punkty.compareTo(new BigDecimal(-1))!=0)
{
liczymy(findViewById(android.R.id.content));
}}
And in case someone asking "what 'tablica' gets from intent?":
BigDecimal[][] tablica = new BigDecimal[16][3];
//here i get data from file and put in inside "tablica"
Bundle doble = new Bundle();
doble.putSerializable("doble", tablica);
Intent intent = new Intent(Starter.this, MyActivity.class);
intent.putExtra("doble", doble);
startActivity(intent);
Any idea what's wrong?
Try switching your array implementation (BigDecimal[] []) to ArrayList.
If you want to pass an Array through an intent on Android versions
prior to Android 5.0.1 (maybe some older versions work aswell, but up
to Android 4.3 it is NOT working) You'll have to work around it. You
could do this by converting your Array to an ArrayList.
Then you would be casting it something like this:
(ArrayList<ArrayList<BigDecimal>>) doble.getSerializable("doble");

My app when installed on my relatively new Huawei running Oreo 8.0 is able to launch and run the app smoothly. The app also runs fine on the Nexus Emulator running Lollipop. However, on my other phone running KitKat 4.4 the app crashes when launched.
I think the problem occured when I added a default NavigationDrawerActivity.

As suggested in the comments section, I was actually missing some other res -v21 folders which support API level 21 for Android KitKat. For some reason I didn't move them into my new project. It is working now, thank you.
i tried to use a library (https://android-arsenal.com/details/1/1414) for a sticky header in a list view. I this configured well the library because i can use classes from there.
The code i'm using is like in the example from the link above, but i get a nullPointerExeption at ".build();"
This is the code :
public class MainActivity extends Activity {
ViewGroup containerLayout ;
ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
containerLayout = (ViewGroup) findViewById(R.id.containerLayout);
listView = (ListView) findViewById(R.id.list);
String[] values = new String[]{"Android List View",
"Adapter implementation",
"Simple List View In Android",
"Create List View Android",
"Android Example",
"List View Source Code",
"List View Array Adapter",
"Android Example List View",
};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, values);
// Assign adapter to ListView
listView.setAdapter(adapter);
StikkyHeaderBuilder.stickTo(listView)
.setHeader(R.id.header,containerLayout )
.minHeightHeader(250)
.animator(new IconAnimator())
.build();
} }
And this is my error log:

I am trying to pass String data using intent from Authorites.class to Issues.class . When a radio button is chosen and button is clicked, 1st activity has to show toast as well as pass the Radio button value to next activity.
When i choose the radio-button and press the button in Authorites.class,the app stops and exits. Plz find where have i gone wrong
public class Authorities extends AppCompatActivity {
/**
* ATTENTION: This was auto-generated to implement the App Indexing API.
* See https://g.co/AppIndexing/AndroidStudio for more information.
*/
//private GoogleApiClient client;
RadioButton auth_button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_authorities);
final RadioGroup auth_grp = (RadioGroup) findViewById(R.id.rgrp);
Button button1 = (Button) findViewById(R.id.authselect);
button1.setOnClickListener( new View.OnClickListener(){
#Override
public void onClick (View v){
// store the text corresponding to the RadioButton which is clicke
int sa = auth_grp.getCheckedRadioButtonId();
auth_button = (RadioButton) findViewById(sa);
// String auth=auth_button.getText().toString();
Toast.makeText(Authorities.this, auth_button.getText(), Toast.LENGTH_SHORT).show();
Intent i;
i=new Intent(Authorities.this, Issues.class);
// Intent i = new Intent().setClassName("com.example.chethan.wapp.Authorities", "com.example.chethan.wapp.Issues");
// i.putExtra("Auth",auth);
// Starts TargetActivity
// Authorities.this.startActivity(i);
startActivity(i);
}
});
}
Issues.class should recieve the Intent data returned from previous activity
public class Issues extends AppCompatActivity {
CheckBox mws,sl,swc,sws,dr;
Button b2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// mws=(CheckBox)findViewById(R.id.mws);
// sl=(CheckBox)findViewById(R.id.sl);
// swc=(CheckBox)findViewById(R.id.swc);
// sws=(CheckBox)findViewById(R.id.sws);
// dr=(CheckBox)findViewById(R.id.dr);
b2=(Button)findViewById(R.id.nxt);
Bundle extras = getIntent().getExtras();
String value1 = extras.getString("Auth");
Toast.makeText(getApplicationContext(),"Authority you chose is:\n"+value1,Toast.LENGTH_LONG).show();
}
Here's the log cat:

Because you are getting string value1 data from getString("Auth") of Intent in Issues class but in Authorities class you are not putting any ("Auth") value in Intent obj.
So uncomment this line...
i.putExtra("Auth",auth);
then run the project...
I've programmed a game for android, everything works fine, but now I want my app to have Google play Games services (leaderboards and achievements). I used the Google example code to log in to the Google services (no errors in the script), but every time I want to connect with my App in debug mode, I get this error:

And the App crashes. Here's my code for the MainActivity where I want it to connect:
public class MainActivity extends BaseGameActivity implements
GameHelper.GameHelperListener, View.OnClickListener {
public static int REQUEST_LEADERBOARD = 1002;
boolean mExplicitSignOut = false;
boolean mInSignInFlow = false;
GoogleApiClient mClient() {
return null;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
setRequestedClients(BaseGameActivity.CLIENT_GAMES | BaseGameActivity.CLIENT_APPSTATE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.startbutton);
button.setOnClickListener (this);
Button highscorebutton = (Button)findViewById(R.id.highscorebutton);
highscorebutton.setOnClickListener(this);
findViewById(R.id.sign_in_button).setOnClickListener(this);
findViewById(R.id.sign_out_button).setOnClickListener(this);
}
public void onClick(View view) {
if(view.getId()==R.id.startbutton) {
startActivityForResult(new Intent(this, buttonActivity.class), 1);
} else if(view.getId()==R.id.highscorebutton) {
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)),REQUEST_LEADERBOARD);
} else if (view.getId() == R.id.sign_in_button) {
// start the asynchronous sign in flow
beginUserInitiatedSignIn();
}
else if (view.getId() == R.id.sign_out_button) {
// sign out.
signOut();
// show sign-in button, hide the sign-out button
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Games.Leaderboards.submitScore(getApiClient(), getString(R.string.the_best_players), resultCode);
if(requestCode==1) {
if(resultCode > leseHighscore()) {
schreibeHighscore(resultCode);
}
}
}
#Override
public void onSignInFailed() {
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
#Override
public void onSignInSucceeded() {
View a = findViewById(R.id.highscorebutton);
a.setVisibility(View.VISIBLE);
View b = findViewById(R.id.button3);
b.setVisibility(View.VISIBLE);
findViewById(R.id.sign_in_button).setVisibility(View.GONE);
findViewById(R.id.sign_out_button).setVisibility(View.VISIBLE);
}

Thanks, GoogleWelt
According to the official documentation, "Before any operation is executed, the GoogleApiClient must be connected"
When the user in not connected(signed in) and clicks to show leaderboards or achievements, it results in the exception thrown. Modify your code for launching the leaderboard like this:
} else if(view.getId()==R.id.highscorebutton) {
if (isSignedIn())
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)), REQUEST_LEADERBOARD);
else showAlert("Please sign in to view leaderboards");
}
Use the same logic for showing achievements:
if (isSignedIn())
startActivityForResult(Games.Achievements.getAchievementsIntent(getApiClient()), REQUEST_ACHIEVEMENT);
else showAlert("Please sign in to view achievements");
Check the part where you are getting ApiClient i.e. getApiClient().
Write the code below to see if GoogleApiClient is Connected or not.
GoogleApiClient mGoogleApiClient;
if(mGoogleApiClient.isConnected()){
// good
}else{
//connect it
mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);
}
I want to know why my application is throwing a runtime exception when I run it? I used to the code in the following link for my application,
dynamically add and remove view to viewpager.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar ab=getActionBar();
pagerAdapter = new MainPagerAdapter();
pager = (ViewPager) findViewById (R.id.pager);
pager.setAdapter (pagerAdapter);
inflater = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v0 = (FrameLayout) inflater.inflate (R.layout.listlayout, null);
Button button=(Button)findViewById(R.id.button1);
button.setOnClickListener(this);
pagerAdapter.addView (v0, 0);
pagerAdapter.notifyDataSetChanged();
}
#Override
public void onClick(View v) {
if(v.getId()==R.id.button1)
{
pagerAdapter.addView (v0);
pagerAdapter.notifyDataSetChanged();
}
}

the object on line 43 of your code within your onCreate method is null. Most likely the target of one of your findViewById calls is not returning what you expect it to.
