该应用程序需要使电话拨出，并附加一些 DTMF 音调。这个电话会定期发生，需要在重启时启动后台服务，或者主活动启动（后者主要是调试）。我在阳光下获得了所有许可，但我仍然无法做到这一点。
背景：电话被用作机舱的远程监视器（+ADK 板），向我发送与附加音调相关的数据，然后挂断。
- Android 的特定版本是 2.3.6，在预付费的 ATT Fusion 2 上。
我看过一些票，上面说最初可以发送 DTMF 音调 - 但不能在通话期间发送。这可以。我不确定会有什么不同。
我已经很久没有为 Android 编程了，所以请放轻松。
我收到的错误是：
06-05 14:42:41.019: W/ActivityManager(195): Unable to start service Intent { act=android.intent.action.CALL dat=tel:xxx-xxx-xxxx flg=0x10000004 }: not found
呼叫服务接收者：
public class CallServiceReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, CallService.class);
context.startService(service);
}
}
呼叫服务：
public class CallService extends Service {
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Intent call = new Intent(Intent.ACTION_CALL);
String number = "XXX-XXX-XXXX"; // US phone number
String tones = "1234*5678*9*1234#";
Log.i("wtf", "Dialing: " + mumber);
Log.i("wtf", "Append tones: " + tones);
call.setData(Uri.parse("tel://" + number + "," + tones));
call.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
call.addFlags(Intent.FLAG_FROM_BACKGROUND);
this.getBaseContext().startService(call);
return Service.START_NOT_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
public class MyBinder extends Binder {
CallService getService() {
return CallService.this;
}
}
}
首先，我尝试在 Activity 启动 20 秒后调用它（它会重复，但我现在将标志设置为“0”）。
从活动开始：
public class StartFromActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AlarmManager service = (AlarmManager) this.getBaseContext()
.getSystemService(Context.ALARM_SERVICE);
Intent callServiceIntent = new Intent(this.getBaseContext(), CallServiceReceiver.class);
PendingIntent pendingCallServiceIntent = PendingIntent.getBroadcast(this.getBaseContext(), 0, callServiceIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar callServiceStart = Calendar.getInstance();
callServiceStart.add(Calendar.SECOND, 20);
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
callServiceStart.getTimeInMillis(), 0, pendingCallServiceIntent);
}
}
然后，我尝试在启动后 20 秒从服务调用调用（它会重复，但我现在将标志设置为“0”）。
OnRestartReceiver：
public class OnRestartReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
AlarmManager service = (AlarmManager) this.getBaseContext()
.getSystemService(Context.ALARM_SERVICE);
Intent callServiceIntent = new Intent(this.getBaseContext(), CallServiceReceiver.class);
PendingIntent pendingCallServiceIntent = PendingIntent.getBroadcast(this.getBaseContext(), 0, callServiceIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar callServiceStart = Calendar.getInstance();
callServiceStart.add(Calendar.SECOND, 20);
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
callServiceStart.getTimeInMillis(), 0, pendingCallServiceIntent);
}
}
清单看起来像：
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<activity android:name=".StartFromActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
</intent-filter>
</activity>
<receiver
android:name=".OnRestartReceiver"
android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<receiver android:name=".CallServiceReceiver"/>
<service android:name=".CallService"/>
</application>
有人对此有见识吗？
