camera - android.intent.action.CAMERA_BUTTON not broadcasting on Desire Z (Froyo)? -

-

i have hard time intercepting hw camera button on desire z (froyo). wrote sample runs fine on g1 (1.6) not on aforementioned phone.

androidmanifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="net.company" android:versioncode="1" android:versionname="1.0"> <uses-sdk android:minsdkversion="4" />  <application android:icon="@drawable/icon" android:label="@string/app_name">     <activity android:name=".camerareceivertestactivity"         android:label="@string/app_name">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>     <receiver android:enabled="true" android:exported="true"         android:name=".camerabuttonreceiver">         <intent-filter android:priority="999">             <action android:name="android.intent.action.camera_button" />             <category android:name="android.intent.category.default" />         </intent-filter>     </receiver> </application> </manifest>

and camerabuttonreceiver.java

package net.company;  public class camerabuttonreceiver extends broadcastreceiver {   static {     log.w("cbr", "onreceive clazz init");   }    @override   public void onreceive(context context, intent intent) {       log.w("cbr", "onreceive camera");       abortbroadcast();   } }

on g1 (1.6) see both messages press camera button , default camera app suppressed. however, on desire z (froyo) no such thing happens. after playing priority, code/xml declarations dare phone sends broadcast other name.

there no requirement device manufacturer send broadcast when camera button clicked, reading of compatibility definition document. might used foreground activity on desire z. don't have z , cannot confirm tests.

since vast majority of android devices not have camera button @ all, need ensure app works without such button, , advise users camera button may or may not work app depending upon device.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
