java - Application not running, android (eclipse) -


i wanted run applications directly through device. did necessary configurations , when run application eclipse lists devices choose from. device there , has serial number of 'samsung-gt_s5570..' target of 2.3.4. when click ok says installed , done, how come application doesn't start on phone ? there step run application or start ? out of curiosity mounting usb having not starting ?

update manifest file

   <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myapp" android:versioncode="1" android:versionname="1.0" >  <uses-sdk     android:minsdkversion="8"     android:targetsdkversion="17" />  <application     android:allowbackup="true"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" > </application>      </manifest>

you need have activites declared in manifest or won't run. also, need 1 entry point app or won't know start. here example of mine. note launcher , main intent filters

 <activity         android:name="com.some.example.loginscreen"         android:configchanges="keyboardhidden|orientation|locale"         android:label="" >          <intent-filter>              <action android:name="android.intent.action.main" />               <category android:name="android.intent.category.launcher" />         </intent-filter>       </activity>

note section in intent filters docs below

most applications have way start fresh, without reference particular data. activities can initiate applications have filters "android.intent.action.main" specified action. if represented in application launcher, specify "android.intent.category.launcher" category:

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
