我有兩個相對簡單的代碼。一項主要活動和一項意向服務。爲什麼我無法啓動我的IntentService？
主要活動
public class IntentServiceTest1Activity extends Activity {
/** Called when the activity is first created. */
public class ResponseReceiver extends BroadcastReceiver {
public static final String ACTION_RESP =
"com.mamlambo.intent.action.MESSAGE_PROCESSED";
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
TextView result = (TextView) findViewById(R.id.txt_result);
String text = intent.getStringExtra(SimpleIntentService.PARAM_OUT_MSG);
result.setText(text);
}
}
private ResponseReceiver receiver;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
IntentFilter filter = new IntentFilter(ResponseReceiver.ACTION_RESP);
filter.addCategory(Intent.CATEGORY_DEFAULT);
receiver = new ResponseReceiver();
registerReceiver(receiver, filter);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener(){
public void onClick(View v){
EditText input = (EditText) findViewById(R.id.txt_input);
String strInputMsg = input.getText().toString();
Intent msgIntent = new Intent(IntentServiceTest1Activity.this, SimpleIntentService.class);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_MSG, strInputMsg);
startService(msgIntent);
}
});
}
}
意向服務
public class SimpleIntentService extends IntentService {
public static final String PARAM_IN_MSG = "imsg";
public static final String PARAM_OUT_MSG = "omsg";
public SimpleIntentService() {
super("SimpleIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
String msg = intent.getStringExtra(PARAM_IN_MSG);
SystemClock.sleep(30000); // 30 seconds
String resultTxt = msg + " "
+ DateFormat.format("MM/dd/yy h:mmaa", System.currentTimeMillis());
Intent broadcastIntent = new Intent();
broadcastIntent.setAction(ResponseReceiver.ACTION_RESP);
broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
broadcastIntent.putExtra(PARAM_OUT_MSG, resultTxt);
sendBroadcast(broadcastIntent);
}
}
的logcat說
06-26 04:16:00.545: W/ActivityManager(67): Unable to start service Intent {
cmp=com.intentservicetest1/.SimpleIntentService (has extras) }: not found
我能做些什麼來糾正呢？
