Android widget background color not updating - android-widget

I want to change the widget background transparency dynamically. The user can define a custom value in percent in my SettingsActivity. After I call updateWidget() from my activity the widget does not update immediately. It is only working if I re-add the widget.
When I set a breaking I see that updateWidgetListView() is called.

getmap is deprecated getMapAsync doesnt work

My app call getmap() method and notice that is depracated and I've to use getMapAsync() instead, however I've read all posts everywhere on the internet and none helped me. Sometimes I got "null pointer return message". I'll hope someone help me to do that.....
My MapFragment.java:
private void setUpMapIfNeeded() {
if (map == null) {
map = ((MapView) view.findViewById(R.id.map)).getMap();
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
map.setMyLocationEnabled(false);
map.getUiSettings().setMyLocationButtonEnabled(false);
map.getUiSettings().setZoomControlsEnabled(false);
btnMyLocation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Location loc = map.getMyLocation();
if (myLocation != null) {
LatLng latLang = new LatLng(myLocation.getLatitude(),
myLocation.getLongitude());
animateCameraToMarker(latLang, true);
}
}
});
map.setOnCameraChangeListener(new OnCameraChangeListener() {
public void onCameraChange(CameraPosition camPos) {
if (currentZoom == -1) {
currentZoom = camPos.zoom;
} else if (camPos.zoom != currentZoom) {
currentZoom = camPos.zoom;
return;
}
if (!isMapTouched) {
curretLatLng = camPos.target;
if (!isAddDestination) {
// layoutMarker.setVisibility(LinearLayout.VISIBLE);
if (listType.size() > 0) {
stopUpdateProvidersLoaction();
getAllProviders(curretLatLng);
}
getAddressFromLocation(camPos.target, etSource);
}
}
isMapTouched = false;
}
});
}
}
The onCreateView:
#Override

.setPreviewFpsRange(): Having problems updating frames per second in camera .setParameters()

UPDATED 28 October 2015 to reflect current progress.
I have an application that allows the user to set camera parameters for Motion JPEG recording, create an MJPEG file, and then the user can modify those settings and create another file with the updated settings. I am having a problem updating the frames per second setting when the initial value is something other than 30 FPS. When the initial value is 30 FPS, I can update to a different FPS level and sucessfully record a video AT THAT LEVEL. However, I cannot update from a level that is not equal to 30FPS to another FPM level. I get a crash with LogCat showing a problem at
camera.setParameters(parameters);
Full LogCat of error is below,

Screenshot: Showing fields, buttons, and surface config
Resolution: It appears that much of the above erratic behaviour may be related to the primary testing device which is a Panasonic Toughpad JT-B1. Running
.getSupportedPreviewFpsRange();
on this device returns a range of 8,000-30,000 fps. However, many values in this range result in crashes, and some values outside of this range appear to work fine. Testing a Samsung S4 Active resulted in none of these inconsistencies, with all of the values in the returned range (4,000 - 30,000) working fine, and no tested values outside of this range demonstrating any functionality as expected.
Camera API does not allow to set the preview FPS range to arbitrary values. You are supposed to query the camera parameters for the list of supported ranges, and any other combination is not guaranteed to work.
In principle, using unsupported values for Camera.setParameters() is undefined behavior. Different devices will fail or work differently when you try the same inputs.
Definitely, though, you should stop preview to change camera parameters, and restart the preview after that.
Other than that, you probably can use a workaround to hold on to supported parameters. To achieve 2 fps, and switch to 10 fps, you don't need to change camera settings. Your logic can filter out relevant frames in your onPreviewFrame() by timestamp.
Furthermore, your code is suboptimal when it comes to preview callbacks. First of all, you should open the camera on a separate handler thread, then the preview callbacks will not arrive on the UI thread (the newer versions of Android become even more jealous about apps hijacking the Main thread for CPU or network intensive tasks).
Second, consider using camera.setPreviewCallbackWithBuffer() to avoid unnecessary garbage collection. An extra advantage of this technique is that if you only prepare one preview buffer, you will only receive preview callbacks when you release it. So, you can simply use the code:
public void onPreviewFrame(byte[] data, Camera camera) {
long timestampBeforecompression = SystemClock.uptimeMillis();
compress(data);
long compressionMillis = SystemClock.uptimeMillis() - timestampBeforecompression;
SystemClock.sleep(1000000/intFramesPerSecond - compressionMillis);
camera.addCallbackBuffer(data);
}
Maybe, you can be more precise if you also compensate for the current camera frame rate, but this is probably not critical when speaking about 2 or 3 FPS.
Finally, there is another hint: many devices still support the deprecated setPreviewFrameRate(), and even declare the supported FPS values that may be of interest for you:

GetChildView gets not called

I have searched similar threads but they didn't help me and they were light different or they still are unanswered, so I'll describe my trouble.
I have an ExpandableListView with a custom ExpandableListAdapter and I can show my Groups but not my Children. GetChildView don't get called anyway.
I would thank you for your Help.
EDIT:
If I log this section
...
client = (ExpandableListView)row.findViewById(R.id.field_expandable_list);
client.setFocusable(false);
client_adapter = new ClientAdapter(context, titles, allFields);
client.setAdapter(client_adapter);
Log.i("TAG", "WmsMApActivity::doClient:: Adapter #children: "+client_adapter.getChildrenCount(0)+
" ExpListView #children: "+client.getChildCount());
...
, then I get that
I/TAG(692): WmsMApActivity::doClient::0 Adapter #children: 13 ExpListView #children: 0
So, my Adapter gets Data but the variable client (ExpandableListView) don't realize, it has data although I properly set it.
My code is the following
Main Code
// view = Item of my ListView. We come from a OnClickItem Method
private void doClient(View view) {
ArrayList<String> titles = new ArrayList<String>();
titles.add("fields");
ArrayList allFields = transformFarmsResult(parentItems);

((ViewGroup) view).removeView(lin_layout_field_list);
} else {

// ----------- Inflating ExpandableListView "Fields"

View row = inflater.inflate(R.layout.field_list, null);
client = (ExpandableListView)row.findViewById(R.id.field_expandable_list);
// Adapter Population
client_adapter = new ClientAdapter(context, titles, allFields);
client.setAdapter(client_adapter);

params.addRule(RelativeLayout.ALIGN_LEFT, title_tv.getId() );

EDIT(2):
As said, it's no problem cause of Layouts or ClientAdapter, so that it works fine in this example
public class ClientActivity2 extends Activity{
private ExpandableListView client;
private ClientAdapter client_adapter;
private ArrayList children;
private ArrayList<String> groups;
private LayoutInflater inflater;
private LinearLayout lin_layout_probe;
private Context context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.field_list);
context = getApplicationContext();
prepareData();
ExpandableListView client = (ExpandableListView)findViewById(R.id.field_expandable_list);
client_adapter = new ClientAdapter(context, groups, children);
client.setAdapter(client_adapter);
client.expandGroup(0);
}
private void prepareData() {
children = new ArrayList();
HashMap<String,Object> hm1 = new HashMap<String,Object>();
hm1.put(Constants._FIELDNAME,"Child1");
children.add(hm1);
HashMap<String,Object> hm2 = new HashMap<String,Object>();
hm2.put(Constants._FIELDNAME,"Child2");
children.add(hm2);
HashMap<String,Object> hm3 = new HashMap<String,Object>();
hm3.put(Constants._FIELDNAME,"Child3");
children.add(hm3);
groups = new ArrayList<String>();
groups.add("Group1");
}
}
Now it comes what confuses me...
If I test all(Adapter and the same calls) with a simple Activity, which has a clickable TextView at its main layout then works fine!
If I click this TextView then the ExpandableListView prompts with properly populated Group and Children and they are expandable/collapsable.
If I test like my last post hier,(ExpandableListView embedded in a ListView Item) so, the ExpandableListView prompts, if I click that the ExpandableListView of that Item
then the groups are populated but not the children. GetChildView gets never called!!!(I used LogCat, so I'm completely sure)
I have seen, many people had troubles with clicks in ExpandableListViews in ListViewItems, my case is different, I can perform that, my trouble is understanding, why with a TextView works fine that ExpandableListView Population via my custom BaseExpandableListAdapter but not in a ListView Item.
Solved
In my first level Adapter (An adapter for the first level ExpandableListView) I modified the getChildView Method
...
// Member Field
private ExpandableListView expandable_field_list;
...
#Override
public View getChildView(int groupPosition, int childPosition,boolean isLastChild, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if ( groupPosition == 1 ) {
if ( expandable_field_list == null ) {
expandable_field_list = new CustomExpandableListView(context);
// Here I initialize the second and third Level
client_adapter = new ClientAdapter(context, groups, children);
expandable_field_list.setAdapter(client_adapter);
} else {
client_adapter.notifyDataSetChanged();
}
convertView = expandable_field_list;
}
return convertView;
}
...
And CustomExpandableListView looks like this
public class CustomExpandableListView extends ExpandableListView {
private boolean expanded = true;
public CustomExpandableListView(Context context) {
super(context);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (isExpanded()) {
// View.MEASURED_SIZE_MASK represents the largest height possible.
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
} else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
#Override
protected void onDetachedFromWindow() {
try {
super.onDetachedFromWindow();
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
}
public void setIsExpanded(boolean expanded) {
this.expanded = expanded;
}
public boolean isExpanded() {
return expanded;
}
}
That is its aspect now as desired

Your data goes through a few steps before making it to the ListView, so the source of the problem could be in one of a few different steps. If you debug your code and check the value of m_result at the beginning of getDir(), you can determine where the problem is coming from. If the value is as expected, there's probably an issue in getDir(), whereas if there's a problem with the string, the issue is probably in doInBackground() (and easy to spot if you know what's wrong with the result, as it turned out).

Why am I getting a null pointer exception?

The title of this problem describes my problem. I have tried fixing this for a while and i am tired of searching and would like some help please. It used to work until I added the Handler and runner. I am trying to make an application that is a simple clock application that the user can set to any time that they want to. Whenever I go to run the application, it opens and then says it would not start properly. This is an activity that is set by another activity and then it changes the values it receives, it also displays these values in textviews.

Thank you.
int Hour = extras.getInt("HoursS");
Hour = Hours;
int Minute = extras.getInt("MinutesS");
Minute = Minutes;
int Second = extras.getInt("SecondsS");
Second = Seconds;
String TimeOfDaySs = extras.getString("TimeOfDayS");
TimeOfDaySs = TimeOfDayS;
Change above code with this::
int Hour = extras.getInt("HoursS");
Hours = Hour;
int Minute = extras.getInt("MinutesS");
Minutes = Minute;
int Second = extras.getInt("SecondsS");
Seconds = Second;
String TimeOfDaySs = extras.getString("TimeOfDayS");
TimeOfDayS = TimeOfDaySs;
Simply, u were getting null pointer exception bcoz u were setting null values to Hour,Minute,Second and TimeOfDaySs and accessing them.
Cheers....!!!
