google maps - MapsDemo not working + android -

-

i trying mapsdemo project shipped google add-ons work. got md5 fingerprint of default debug certificate , using generated maps api key , used in layout file. in manifest file have added permissions required it. manifest file looks like

<uses-permission android:name="android.permission.internet"></uses-permission> <uses-permission android:name="android.permission.access_fine_location"></uses-permission>  <uses-sdk android:minsdkversion="3" />  <application android:label="@string/activity_sample_code"         android:icon="@drawable/app_sample_code" >      <uses-library android:name="com.google.android.maps" />     <activity android:name="com.example.android.apis.mapsdemo" android:label="mapsdemo">         <intent-filter>             <category android:name="android.intent.category.launcher"></category>             <action android:name="android.intent.action.main"></action>         </intent-filter>    </activity>      <!-- ************************************* -->     <!--      view/widget package samples      -->     <!-- ************************************* -->      <activity android:name="com.example.android.apis.view.mapviewdemo" android:label="mapview">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.sample_code" />         </intent-filter>     </activity>      <activity android:name="com.example.android.apis.view.mapviewcompassdemo" android:label="mapview , compass">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.sample_code" />         </intent-filter>     </activity>

my maps layout file looks 

 <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/main"     android:layout_width="fill_parent"      android:layout_height="fill_parent">     <com.google.android.maps.mapview         android:layout_width="fill_parent"          android:layout_height="fill_parent"         android:enabled="true"         android:clickable="true"         android:apikey="0msdghc7pl9izft4m7vdaxrreci8jizebeulpvw"         /> </linearlayout>

but after this, see blank gid screen. no maps shown. please me in resolving issue. doing wrong here??

this think google maps api v1 deprecated. v2 visit https://developers.google.com/maps/documentation/android/ api documentation.

also can try quick start guide https://docs.google.com/document/pub?id=19nqzvkp-cvld7_vrpwnhfl-ae9fjbjysowonzztnhzw

enjoy. :-)

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
