I'M developing on a finding nearby place on GooGle map v2.project contains no error but there is unable to find activity error in Logcat.
so i think the problem is in oncreate() method whiche i set Adapter.
could you cheek my code please.

I think you should have to change
SupportMapFragment fragment = ( SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
to
SupportMapFragment fragment = ((SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map));
For more info please look at this answer...
you should add these line in your layout file
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
I think you r using com.google.android.gms.maps.MapFragment.

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'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:

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");

Just update
String read_query = "select * from"+ ContactsTask.ContactsEntry.TABLE_NAME;
to
String read_query = "select * from "+ ContactsTask.ContactsEntry.TABLE_NAME;
Always close cursor. update your initializeData method
public void initializeData() {
try {
contactsList = new ArrayList<>();
try{
c = db.rawQuery(read_query,null);
c.moveToFirst();
while (!c.isLast())
{
names = c.getString(0);
phone = c.getInt(1);
email = c.getString(2);
address = c.getString(3);
contactsList.add(new Contacts(names,phone,email,address));
}
c.isLast();
names = c.getString(0);
phone = c.getInt(1);
email = c.getString(2);
address = c.getString(3);
contactsList.add(new Contacts(names,phone,email,address));
} catch (Exception e) {
// exception handling
} finally {
if(c != null){
c.close();
}

I am having a few issues running my custom CursorAdapter in my application. According to my logcat, the error I get:
11-08 06:41:03.228 6109-6109/? W/System.err? java.lang.RuntimeException: Unable to start activity ComponentInfo{com.app.name/com.app.name.MyActivity}: java.lang.NullPointerException

11-08 06:41:03.231 6109-6109/? E/AndroidRuntime? FATAL EXCEPTION: main
occurs at line 71 which sets the adapter (obj.setAdapter(myAdapter)). Initially I thought my database data retrieve function (Cursor chatCursor = mydb.selectConversation(msgId);) did not return any data but after testing it with the chatCursor.getCount() function, I realized that was not the case. Kindly assist me in solving this issue. Below are the codes for my activity, adapter and logcat. Thanks in advance.
MyAdapter.java
public class MyAdapter extends CursorAdapter {
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
public MyAdapter(Context context, Cursor cursor) {
super(context, cursor, 0);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.chat_left, parent, false);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
TextView user = (TextView) view.findViewById(R.id.reply_user);
TextView msg = (TextView) view.findViewById(R.id.reply_msg);
String theTime = cursor.getString(cursor.getColumnIndexOrThrow("message_id"));
String theMessage = cursor.getString(cursor.getColumnIndexOrThrow("message"));
user.setText(theTime);
msg.setText(String.valueOf(theMessage));
}
}
MyActivity.java
public class MyActivity extends ListActivity {
//Utils Class
Utils util;
final Context context = this;
private ProgressBar dialog;
ListView obj;
DBHelper mydb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view);
util = new Utils(this);
mydb = new DBHelper(this);
Bundle extras = getIntent().getExtras();
final Integer msgId = extras.getInt("id");
obj = (ListView) findViewById(R.id.list);
Cursor chatCursor = mydb.selectConversation(msgId);
MyAdapter myAdapter = new MyAdapter(this, chatCursor);
obj.setAdapter(myAdapter);
}

Take a look to your activity_view.xml. Probably the listview ID isn't "list" as you state when you try to find it with findViewById(R.layout.list).
I am currently working on the new Google Maps Android API v2.
My MapActivity class is working with my Samsung galaxy s3 ans s2 with the code below:
However, there are some particular devices are not working such as: GT-S5830i
class MapActivity extends FragmentActivity implements OnMapClickListener, OnMapLongClickListener, OnMarkerClickListener
{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
tvLocInfo = (TextView)findViewById(R.id.locinfo);
android.support.v4.app.FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment myMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
myMap = myMapFragment.getMap();
myMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
ArrayList<Cooridnates> cooridnatesList = MainActivity.getList();
for(int i=0;i<cooridnatesList.size();i++)
{
//Toast.makeText(MapActivity.this, "SIZE : " + " " + cooridnatesList.size(), Toast.LENGTH_LONG).show();
LatLng point = new LatLng(cooridnatesList.get(i).getLat(),cooridnatesList.get(i).getLon());
tvLocInfo.setText("markers added");
myMap.addMarker(new MarkerOptions().position(point).title(point.toString()));
center=CameraUpdateFactory.newLatLng(point);
}
CameraUpdate zoom=CameraUpdateFactory.zoomTo(16);
myMap.moveCamera(center);
myMap.animateCamera(zoom);
myMap.setOnMapClickListener(this);
myMap.setOnMarkerClickListener(this);
markerClicked = false;
}
For some reason, I am getting this error:

You function MainActivity.getList() probably returned an empty list, so for loop doesn't execute center=CameraUpdateFactory.newLatLng(point);.
it seems center is null in this >> myMap.moveCamera(center);, make an appropriate check on this variable before passing it in moveCamera method.
It seems problem is here. center might have null value, So to get proper explanation debug your application.
center is initialzed here.
center=CameraUpdateFactory.newLatLng(point);
It might assign null in center.
myMap.moveCamera(center); <<<PROBLEM is here
if(center != null )
myMap.moveCamera(center);
