arm - How do I make an embedded Android OS with just one app? -

-

i make own embedded system built on android (arm) using devices distributed android without launcher.

or

i want start android application launched on top , refuse close , shutdown android app.

essentially you're trying have custom build of aosp "home" application. if /packages/apps/launcher2 you'll find code default home screen.

if @ androidmanifest.xml file in there, you'll see this:

     <activity         android:name="com.android.launcher2.launcher"         android:launchmode="singletask"         android:cleartaskonlaunch="true"         android:statenotneeded="true"         android:theme="@style/theme"         android:screenorientation="nosensor"         android:windowsoftinputmode="stateunspecified|adjustpan">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.home" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.monkey"/>         </intent-filter>     </activity>

essentialy, says activity reacts

android.intent.category.home intent.

when system finishes booting (the activitymanager more specifically), sends intent. so, if want app start instead of launcher, create app similar intent filter , remove default launcher2 (take out of list in build/target/product/generic.mk , put yours instead). make sure relevant .mk file has this:

local_overrides_packages := home

so long app doesn't provide way user launch other apps using icons (like launcher does), no other app started; unless of course sends activity-starting intent other path 1 controlled app - using "am" command on target's android shell.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
