android - security vulnerabilities in using launching activity -


in android , use home screen activity shows registred items .

when launching application, home screen activity launched default.

from settings screen of application, can set password app. once set password. every time launch application. shows password screen. after entering password takes home screen activity.

but hacker point of view, without knowing password, can still go home screen when give command.

    start -n com.share.device/.device.devicelistactivity

this automatically starts home screen activity, though have set password application.

how can restrict access home screen activity, if use "am start" command.

i dont want directly access home screen when there password set application. please suggest how can rectify issue.

introactivity -> devicelistactvity

using "am start" command, can directly start devicelistactivity

androidmanifest.xml

<activity     android:name=".common.introactivity"     android:screenorientation="unspecified"     android:theme="@android:style/theme.notitlebar.fullscreen" >     <intent-filter>         <action android:name="android.intent.action.main" />         <category android:name="android.intent.category.launcher" />     </intent-filter> </activity> <activity     android:name=".device.devicelistactivity"     android:configchanges="orientation|keyboardhidden"     android:screenorientation="unspecified"     android:theme="@android:style/theme.notitlebar" /> </activity>

have login activity set static variable somewhere. in devicelistactivity, check variable. if isn't set, not run activity- instead launch login activity , finish() yourself.

this better if value set coming server, such login token if info coming server.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
