[Q][DEV]Android Development Maps Question

I'm trying to develop (for the liveview) using an SDK and need to get a bitmap of Google Maps.
Code:
//Map Section
public class myMap extends MapActivity {
MapView mapView;
Bitmap bitmap;
boolean created = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
createMap();
}
public void createMap()
{
// build map and mark point
mapView = new MapView(this, "keykeykeykeykeykey");
mapView.setBuiltInZoomControls(false);
GeoPoint point = new GeoPoint(52242730,-884211);
mapView.getController().animateTo(point);
mapView.preLoad();
// copy MapView to canvas
bitmap = Bitmap.createBitmap(400, 800, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
mapView.draw(canvas);
PluginUtils.sendTextBitmap(mLiveViewAdapter, mPluginId, "Loading Map...", 128, 12);
created = true;
}
public void displayMap()
{
if (created == false)
{
createMap();
}
//Display map on device
Bitmap mybit = Bitmap.createBitmap(128, 128, Bitmap.Config.ARGB_8888);
for(int i = 0; i < 128; i++)
{
for(int j = 0; j < 128; j++)
{
mybit.setPixel(i, j, bitmap.getPixel(i, j));
}
}
//white pixel for debugging
mybit.setPixel(64, 64, Color.WHITE);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Is what I've got so far, the code in createMap() was in onCreate() but It didn't seem to be called.
Now it just force closes.
Anyone know how to help? Is there a better place to ask development questions?
Thanks.
-=Edit=-
Oh, and here's the routine calling the map thing, every couple of seconds.
Code:
private class Timer implements Runnable {
@Override
public void run() {
// TODO Auto-generated method stub
myMap theMap = new myMap();
theMap.displayMap();
}
}

Okay, looks like you cant use google street map like this.
Anyone looking for similar solution, I used open street map and downloaded 'slipery tiles' png's. They provide java routines for finding the tile url from lat/lon.

Why my items are not redrawn after invoking `invalidateViews()` ?

Why my items are not redrawn after invoking `invalidateViews()` ?
I ask because i try to refresh `listItems` after a bg-thread notify an image rsc was downloaded.
But nothing is updated. Only after exiting and re-entering the new icons are drawn.
I have an activity with `adapter` of type `SettingValueAdapter extends BaseAdapter`
it has a member:
`private SettingsValue[] values;`
it has two interesting methods:
@override
public View getView(int position, View view, ViewGroup parent) {
AddressItem ai= (AddressItem)getItem(position);
DriveToNativeManager dnm = DriveToNativeManager.getInstance();
if (view == null) {
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = li.inflate(R.layout.address_item, null);
}
view.setTag(R.id.addressItem,ai);
view.setTag(position);
view.findViewById(R.id.fullAddressItemCol).setVisibility(View.VISIBLE);
view.findViewById(R.id.addressItemTouch).setVisibility(View.GONE);
view.findViewById(R.id.addressItemImage).setVisibility(View.GONE);
if (ai != null) {
...
}
view.findViewById(R.id.addressItemIconLayout).setVisibility(View.VISIBLE);
Drawable icon = ResManager.GetSkinDrawable(ai.getIcon() + ".bin");
((ImageView)view.findViewById(R.id.addressItemIcon)).setImageDrawable(icon);
..
}
I attach a callback to the bg-thread (c language) image downloading process.
The callback switches to the ui-thread and calls this `refreshList`:
public void refreshSearchIconsOnSearchActivity() {
Runnable refreshViewEvent = new Runnable() {
@override
public void run() {
Activity currentActivity = AppService.getActiveActivity();
if (currentActivity instanceof SearchActivity) {
Log.d("w", "refreshSearchIconsOnSearchActivity callback running in thread "
+ Thread.currentThread().getId() );
//results list
((SearchActivity) currentActivity).refreshList();
}
}
};
AppService.Post(refreshViewEvent);
}
However, the images are done downloading and are not refreshed on the activity.
They are refreshed only when I leave an re-enter the activity.
What am I missing?

In previous article, we looked at Notification API with Hello SmartWatch demo. In this article, we will focus on Control API.

http://forum.xda-developers.com/smartwatch/sony/tut-smartwatch-app-development-part-3-t2807966
Control API is responsible for
Extension lifecycle: It allows you to start and stop extension using Intent. Extension means SmartWatch Host application.
Control.Intents.CONTROL_START_INTENT
Control.Intents.CONTROL_STOP_INTENT.
Controlling the display: Normally we don't require to control the display. Default screen state is "Auto", for the specific need you can change screen state by using Intent.
Control.Intents.SCREEN_STATE_OFF
Control.Intents.SCREEN_STATE_AUTO
Control.Intents.SCREEN_STATE_DIM
Control.Intents.SCREEN_STATE_ON
Controlling the LEDs: It used to switch on /off LEDs based on notification.
Control.Intents.CONTROL_LED_INTENT
Controlling the vibrator: It allows you to vibrate SmartWatch.
Control.Intents.CONTROL_VIBRATE_INTENT
Key event: It is used to capture hardware key i.e. home, back and menu key, which is available in SmartWatch2.
Control.Intents.CONTROL_KEY_EVENT_INTENT
Touch event: It is used to capture touch events.
Control.Intents.CONTROL_TOUCH_EVENT_INTENT
Control.Intents.CONTROL_SWIPE_EVENT_INTENT
Control.Intents.CONTROL_OBJECT_CLICK_EVENT_INTENT
Sony's Add-on SDK version 2.0 supports ListView and GridView but this article focuses on basic controls only. For the demo I will create a simple layout with ImageView and TextView. I will animate ImageView with thread and also capture onClick event of ImageView.

Click on Android will fire onClick event from host app to extension app
Click on menu hardware button to make menu item visible.
Step 1: Create java class named "HelloControlSmartWatch2.java" and extend with ControlExtension.
Code:
package com.kpbird.hellosmartwatch;
import android.content.Context;
import android.location.Address;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;

private static final int MENU_ITEM_0 = 0;
private static final int MENU_ITEM_1 = 1;
private static final int MENU_ITEM_2 = 2;
private boolean mIsShowingAnimation = false;
private Animation mAnimation = null;
private Handler mHandler;
private ControlViewGroup mLayout = null;
private String TAG = this.getClass().getSimpleName();
private Bundle[] mMenuItemsText = new Bundle[3];
public HelloControlSmartWatch2(Context context, String hostAppPackageName,Handler handler) {
super(context, hostAppPackageName);
if (handler == null) {
throw new IllegalArgumentException("handler == null");
}
mHandler = handler;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.hello_control_2, null);
mLayout = parseLayout(layout);
if(mLayout !=null){
ControlView androidAnim = mLayout.findViewById(R.id.imgHelloControl);
androidAnim.setOnClickListener(new OnClickListener() {
@Override
public void onClick() {
Toast.makeText(mContext, "Button Clicked", Toast.LENGTH_LONG).show();
Log.i(TAG, "Android Button Clicked");

}
});
}
mMenuItemsText[0] = new Bundle();

mMenuItemsText[2].putString(Control.Intents.EXTRA_MENU_ITEM_TEXT, "Item 3");
}
@Override
public void onResume() {
super.onResume();
showLayout(R.layout.hello_control_2, null);
startAnimation();
}
@Override
public void onPause() {
super.onPause();
stopAnimation();
}
@Override
public void onDestroy() {
stopAnimation();
mHandler = null;
};
public static int getSupportedControlWidth(Context context) {
return context.getResources().getDimensionPixelSize(R.dimen.smart_watch_2_control_width);
}

}
@Override
public void onTouch(ControlTouchEvent event) {
Log.i(TAG, "onTouch() " + event.getAction());
}
@Override
public void onObjectClick(ControlObjectClickEvent event) {
Log.i(TAG, "onObjectClick() " + event.getClickType());
if (event.getLayoutReference() != -1) {
mLayout.onClick(event.getLayoutReference());
}

}
}
private void toggleAnimation() {
if (mIsShowingAnimation) {

}
else {
startAnimation();
}
}
private void startAnimation() {
if (!mIsShowingAnimation) {
mIsShowingAnimation = true;
mAnimation = new Animation();
mAnimation.run();
}
}
private void stopAnimation() {
if (mIsShowingAnimation) {
// Stop animation on accessory
if (mAnimation != null) {
mAnimation.stop();
mHandler.removeCallbacks(mAnimation);

}
mIsShowingAnimation = false;
}
}
private class Animation implements Runnable {
private int mIndex = 1;
private boolean mIsStopped = false;
Animation() {
mIndex = 1;
}
public void stop() {
mIsStopped = true;
}
@Override
public void run() {
int resourceId;
switch (mIndex) {
case 1:
resourceId = R.drawable.dancing_android_0;
break;
case 2:
resourceId = R.drawable.dancing_android_1;
break;
default:
Log.e(TAG, "mIndex out of bounds: " + mIndex);
resourceId = R.drawable.dancing_android_0;
break;
}
mIndex++;
if (mIndex > 2) {
mIndex = 1;
}
if (!mIsStopped) {
updateAnimation(resourceId);
}
if (mHandler != null && !mIsStopped) {
mHandler.postDelayed(this, ANIMATION_DELTA_MS);
}
}
private void updateAnimation(int resourceId) {
sendImage(R.id.imgHelloControl, resourceId);
}
};
}
Step 2: Open HelloExtensionService.java and override "createExtensionControl" method. In this method we need to identify accessory type before creating object of HelloControlSmartWatch2 class. To identify accessory type ExtensionUtils class has method named "DeviceInfoHealper".
Code:
@Override
public ControlExtension createControlExtension(String hostAppPackageName) {
// First we check if the API level and screen size required for
// SampleControlSmartWatch2 is supported
boolean advancedFeaturesSupported = DeviceInfoHelper.isSmartWatch2ApiAndScreenDetected(this, hostAppPackageName);
if (advancedFeaturesSupported) {
return new HelloControlSmartWatch2(this,hostAppPackageName, new Handler());
} else {
return null;
}
}
Step 3: Open HelloRegistrationInformation.java and change return value from 0 to 2 of "getRequiredControlApiVersion" method, 0 means our example doesn't require Control API, 1 and 2 represent minimum version of API required. We also need to override method named "isDisplaySizeSupported" for the confirmation of Display Size.
Code:
...
...
@Override
public int getRequiredControlApiVersion() {
return 2;
}
....
@Override
public boolean isDisplaySizeSupported(int width, int height) {
return ((width == HelloControlSmartWatch2.getSupportedControlWidth(mContext)
&& height == HelloControlSmartWatch2
.getSupportedControlHeight(mContext) || width == HelloControlSmartWatch2
.getSupportedControlWidth(mContext) && height == HelloControlSmartWatch2
.getSupportedControlHeight(mContext)) );
}
...
...
Step 4: Finally, Open AndroidManiFest.xml and add following action in HelloExtensionReceiver. It will require to capture onClick, onTouch and onObject click event.
Code:
...
...
<action android:name="com.sonyericsson.extras.aef.control.TOUCH_EVENT" />
<action android:name="com.sonyericsson.extras.aef.control.SWIPE_EVENT" />
<action android:name="com.sonyericsson.extras.aef.control.OBJECT_CLICK_EVENT" />
<action android:name="com.sonyericsson.extras.aef.control.MENU_ITEM_SELECTED" />
...
...
Step 5: Compile & Execute HelloSmartWatch example
Download Source Code​Note: 1. Import project in eclipse 2. Make sure that you change SmartExtensionUtils and SmartExtensionAPI path from project properties.

I have a Slideshow for the Home Page of my app looks sorta like the Houzz apps Home Page, were it displays a new image daily. But their is one issue I am having is that all of my images are coming in so blurry. I've checked the Resolution and it shouldn't be that blurry for no reason at all. I've tried changing setScaleType such as switching it too CENTER, CENTER_CROP, and Etc... None of those seemed to work.

It is a tradition to exchange business cards with new colleges or partners, but keeping physical business cards is not easy at all. To solve this problem, many apps and mini programs providing the electronic business card function have emerged. You must be wondering how to develop such a function for your app.
Try integrating HUAWEI Nearby Service and use its Nearby Message feature to quickly implement the point-to-point business card exchange function. Check out the function demo below.

}
If you are interested in the implementation details, download the source code from GitHub. You can optimize the code based on your app requirements.
Github demo link: https://github.com/HMS-Core/hms-nearby-demo/tree/master/NearbyCardExchange
The development procedure is as follows:
1. Getting Started
If you are already a Huawei developer, skip this step. If you are new to Huawei Mobile Services (HMS), you need to configure app information in AppGallery Connect, enable Nearby Service on the HUAWEI Developers console, and integrate the HMS Core SDK. For details, please refer to the documentation.
2. Adding Permissions
Before using Nearby Message, add the network, Bluetooth, and location permissions. Add the following permissions to the AndroidManifest.xml file of your project:
Code:
<uses-permission android:name="android.permission.INTERNET " />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<!-- The location permission is also required in Android 6.0 or later. -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
1. Code Development
2.1 Submitting a Dynamic Permission Application
Ensure that the Bluetooth and location functions are enabled and the device has been connected to the Internet properly. Then submit a dynamic permission application for the location permission.
Code:
@Override
public void onStart() {
super.onStart();
getActivity().getApplication().registerActivityLifecycleCallbacks(this);
checkPermission();
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
for (int i = 0; i < permissions.length; ++i) {
if (grantResults[i] != 0) {
showWarnDialog(Constants.LOCATION_ERROR);
}
}
}
private void checkPermission() {
if (!BluetoothCheckUtil.isBlueEnabled()) {
showWarnDialog(Constants.BLUETOOTH_ERROR);
return;
}
if (!LocationCheckUtil.isLocationEnabled(this.getActivity())) {
showWarnDialog(Constants.LOCATION_SWITCH_ERROR);
return;
}
if (!NetCheckUtil.isNetworkAvailable(this.getActivity())) {
showWarnDialog(Constants.NETWORK_ERROR);
return;
}
String[] deniedPermission = PermissionUtil.getDeniedPermissions(this.getActivity(), new String[] {
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION
});
if (deniedPermission.length > 0) {
PermissionUtil.requestPermissions(this.getActivity(), deniedPermission, 10);
}
}
2.2 Encapsulating the Business Card Publishing and Subscription APIs
When a subscribed business card message is detected by the onFound method, display it in the business card searching pop-up; when a business card message is no longer discoverable (onLost), delete it from the business card searching pop-up.
Code:
private MessageHandler mMessageHandler = new MessageHandler() {
@Override
public void onFound(Message message) {
CardInfo cardInfo = JsonUtils.json2Object(new String(message.getContent(), Charset.forName("UTF-8")),
CardInfo.class);
if (cardInfo == null) {
return;
}
mSearchCardDialogFragment.addCardInfo(cardInfo);
}
@Override
public void onLost(Message message) {
CardInfo cardInfo = JsonUtils.json2Object(new String(message.getContent(), Charset.forName("UTF-8")),
CardInfo.class);
if (cardInfo == null) {
return;
}
mSearchCardDialogFragment.removeCardInfo(cardInfo);
}
};
private void publish(String namespace, String type, int ttlSeconds, OnCompleteListener<Void> listener) {
Message message = new Message(JsonUtils.object2Json(mCardInfo).getBytes(Charset.forName("UTF-8")), type,
namespace);
Policy policy = new Policy.Builder().setTtlSeconds(ttlSeconds).build();
PutOption option = new PutOption.Builder().setPolicy(policy).build();
Nearby.getMessageEngine(getActivity()).put(message, option).addOnCompleteListener(listener);
}
private void subscribe(String namespace, String type, int ttlSeconds, OnCompleteListener<Void> listener,
GetCallback callback) {
Policy policy = new Policy.Builder().setTtlSeconds(ttlSeconds).build();
MessagePicker picker = new MessagePicker.Builder().includeNamespaceType(namespace, type).build();
GetOption.Builder builder = new GetOption.Builder().setPolicy(policy).setPicker(picker);
if (callback != null) {
builder.setCallback(callback);
}
Nearby.getMessageEngine(getActivity()).get(mMessageHandler, builder.build()).addOnCompleteListener(listener);
}
2.3 Processing the Business Card Exchange Menu
When two users exchange business cards face to face, exchange the business card exchange codes. When the business card message of the remote endpoint is published, subscribe to it.
Code:
private boolean onExchangeItemSelected() {
PinCodeDialogFragment dialogFragment = new PinCodeDialogFragment(passwrod -> {
MyCardFragment.this.publish(passwrod, passwrod, Policy.POLICY_TTL_SECONDS_MAX, result -> {
if (!result.isSuccessful()) {
String str = "Exchange card fail, because publish my card fail. exception: "
+ result.getException().getMessage();
Log.e(TAG, str);
Toast.makeText(getActivity(), str, Toast.LENGTH_LONG).show();
return;
}
MyCardFragment.this.subscribe(passwrod, passwrod, Policy.POLICY_TTL_SECONDS_INFINITE, ret -> {
if (!ret.isSuccessful()) {
MyCardFragment.this.unpublish(passwrod, passwrod, task -> {
String str = "Exchange card fail, because subscribe is fail, exception("
+ ret.getException().getMessage() + ")";
if (!task.isSuccessful()) {
str = str + " and unpublish fail, exception(" + task.getException().getMessage()
+ ")";
}
Log.e(TAG, str);
Toast.makeText(getActivity(), str, Toast.LENGTH_LONG).show();
});
return;
}
mSearchCardDialogFragment.setOnCloseListener(() -> {
MyCardFragment.this.unpublish(passwrod, passwrod, task -> {
if (!task.isSuccessful()) {
Toast.makeText(getActivity(), "Unpublish my card fail, exception: "
+ task.getException().getMessage(), Toast.LENGTH_LONG).show();
}
});
MyCardFragment.this.unsubscribe(task -> {
if (!task.isSuccessful()) {
Toast.makeText(getActivity(), "Unsubscribe fail, exception: "
+ task.getException().getMessage(), Toast.LENGTH_LONG).show();
}
});
});
mSearchCardDialogFragment.show(getParentFragmentManager(), "Search Card");
}, null);
});
});
dialogFragment.show(getParentFragmentManager(), "pin code");
return true;
}
2.4 Adding a Business Card to Favorites
When a user adds a business card to favorites, add the card to the favorites list; when a user removes a business card from favorites, remote the card from the favorites list. In addition, store related data locally.
Code:
@Override
public void onFavorite(CardInfo cardInfo, boolean isFavorite) {
if (isFavorite) {
mFavoriteMap.put(cardInfo.getId(), cardInfo);
} else {
mFavoriteMap.remove(cardInfo.getId());
}
Set<String> set = new HashSet<>(mFavoriteMap.size());
for (CardInfo card : mFavoriteMap.values()) {
set.add(JsonUtils.object2Json(card));
}
SharedPreferences sharedPreferences = getContext().getSharedPreferences("data", Context.MODE_PRIVATE);
sharedPreferences.edit().putStringSet(Constants.MY_FAVORITES_KEY, set).apply();
}
5. Conclusion
This demo uses Nearby Message feature of HUAWEI Nearby Service. What Nearby Message is capable of is more than just developing functions for exchanging business cards face-to-face. Here are some examples:
1. Face-to-face teaming in multiplayer sports games
2. Face-to-face round joining in board games
3. Near-field go-Dutch payment function
4. Music sharing
