我正在尝试检测一个拨出的电话开始播放铃声时的状态。我试过各种方法来检测这种状态。以下是其中一些:
一。使用
PhoneStateListener
:
(
Cannot detect when outgoing call is answered in Android
)
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class CustomPhoneStateListener extends PhoneStateListener {
public void onCallStateChanged(int state, String num) {
Log.d(CallStatusPlugin.TAG, ">>>state changed" + state);
}
}
但是州政府
TelephonyManager.CALL_STATE_IDLE
,
TelephonyManager.CALL_STATE_OFFHOOK
不会给我们这些状态。
2。使用
READ_PRECISE_PHONE_STATE
:
将方法添加到上述电话状态侦听器
public void onPreciseCallStateChanged() {
Log.d(CallStatusPlugin.TAG, "onPreciseCallStateChanged");
}
但是根据我的研究,阅读精确的状态需要应用程序必须是一个系统应用程序。
三。使用
NotificationListener
:
public class CustomNotificationListener extends NotificationListenerService {
public static final String TAG = "CallStatusPlugin";
public CustomNotificationListener() {
Log.v(TAG, ">>> CustomNotificationListener");
}
public void onNotificationPosted(StatusBarNotification sbn) {
Log.i(TAG, "New Notification");
Bundle extras = sbn.getNotification().extras;
if ("Ongoing call".equals(extras.getString(Notification.EXTRA_TEXT))) {
Log.v(TAG, "outgoing call");
} else if ("Dialing".equals(extras.getString(Notification.EXTRA_TEXT))) {
Log.v(TAG, "dialling call");
}
}
}
但这没有帮助,因为操作系统不会在拨出电话的铃声开始播放时更改通知。
四。使用
BroadcastReceiver
:
public class CallBroadcastReceiver extends BroadcastReceiver {
public static final String TAG = "CallStatusPlugin";
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.i(TAG, "CallBroadcastReceiver state: " + state);
// TelephonyManager.EXTRA_FOREGROUND_CALL_STATE = "foreground_state"
Log.d(TAG, "new state >>>>" + intent.getIntExtra("foreground_state", -2));
}
}
但也没有帮助。
5个。使用反射:
我还尝试使用反射获取默认拨号程序的实例,但没有成功:
//com.samsung.android.incallui
Reflections reflections = new Reflections("com.samsung.android.contacts", new SubTypesScanner(false));
final ClassLoader classLoader = this.getClass().getClassLoader();
ClassLoader[] loaders = { classLoader };
ConfigurationBuilder configurationBuilder = (ConfigurationBuilder) reflections.getConfiguration();
configurationBuilder.setClassLoaders(loaders);
Log.d(TAG, "cl" + classLoader.toString());
Set<Class<? extends Object>> allClasses = reflections.getSubTypesOf(Object.class);
Log.d(TAG, "allclasses" + allClasses.toString());
我不能上任何课(也许我没有正确地使用反射)
通过将默认拨号程序(我不想使用)替换为自定义拨号程序来获取
Call
国家。
import android.os.Bundle;
import android.telecom.Call;
import android.telecom.InCallService;
import android.util.Log;
public class CustomInCallService extends InCallService {
public static final String TAG = "CallStatusPlugin";
@Override
public void onCallAdded(Call call) {
Log.d(TAG, "onCallAdded: " + call.getState());
call.registerCallback(
new Call.Callback() {
@Override
public void onConnectionEvent (Call call, String event, Bundle extras) {
Log.d(TAG, "Call.Callback.onConnectionEvent: " + event + ", " + call.getState());
}
@Override
public void onStateChanged (Call call, int state) {
Log.d(TAG, "Call.Callback.onStateChanged: " + state + ", " + call.getState());
}
}
);
}
}
这个
onStateChanged
最后给了我一些东西:
呼叫状态
->9级(
STATE_CONNECTING
)->1个(
STATE_DIALING
)->4个(
STATE_ACTIVE
)(回答时)->7(
STATE_DISCONNECTING
)
但呼叫状态也更改为
状态拨号
当拨出的电话有问题时,例如无法接通已拨号码或电话已关机。所以这意味着我们不能说
DIALING
状态是传出呼叫开始播放铃声的状态。

)
public class OutCallLogger extends BroadcastReceiver {
public static final String TAG = "CallStatusPlugin";
public OutCallLogger() {
Log.e(TAG, "\n\n\nOutCallLogger Instance Created\n\n\n");
}
@Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.i(TAG, "OutCallLogger state: " + state);
String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "Outgoing Number: " + number);
// TelephonyManager.EXTRA_FOREGROUND_CALL_STATE = "foreground_state"
Log.d(TAG, "new state >>>>" + intent.getIntExtra("foreground_state", -2));
Log.d(TAG, "new state >>>>" + intent.getIntExtra("ringing_state", -2));
Log.d(TAG, "new state >>>>" + intent.getIntExtra("background_state", -2));
Log.d(TAG, "new state >>>>" + intent.getIntExtra("disconnect_cause", -2));
final ClassLoader classLoader = this.getClass().getClassLoader();
try {
Class<?> callManagerClass = classLoader.loadClass("com.android.internal.telephony.CallManager");
Log.e(TAG, "CallManager: Class loaded " + callManagerClass.toString());
Method[] methods = callManagerClass.getDeclaredMethods();
for (Method m : methods) {
Log.e(TAG, "Methods: " + m.getName());
}
Method getInstanceMethod = callManagerClass.getDeclaredMethod("getInstance");
getInstanceMethod.setAccessible(true);
Log.e(TAG, "CallManager: Method loaded " + getInstanceMethod.getName());
Object callManagerObject = getInstanceMethod.invoke(null);
Log.e(TAG, "CallManager: Object loaded " + callManagerObject.getClass().getName());
Method getAllPhonesMethod = callManagerClass.getDeclaredMethod("getAllPhones");
Log.e(TAG, "CallManager: Method loaded " + getAllPhonesMethod.getName());
Method getForegroundCallsMethod = callManagerClass.getDeclaredMethod("getForegroundCalls");
Log.e(TAG, "CallManager: Method loaded " + getForegroundCallsMethod.getName());
List foregroundCalls = (List) getForegroundCallsMethod.invoke(callManagerObject);
Log.e(TAG, "Foreground calls: " + foregroundCalls + ", " + foregroundCalls.size());
Method getBackgroundCallsMethod = callManagerClass.getDeclaredMethod("getBackgroundCalls");
Log.e(TAG, "CallManager: Method loaded " + getForegroundCallsMethod.getName());
List backgroundCalls = (List) getBackgroundCallsMethod.invoke(callManagerObject);
Log.e(TAG, "Background calls: " + backgroundCalls + ", " + backgroundCalls.size());
Timer timer = new Timer();
// keep printing all the for 20 seconds to check if we got one
TimerTask doAsynchronousTask = new TimerTask() {
long t0 = System.currentTimeMillis();
@Override
public void run() {
// cancel the timer after 20 seconds
if (System.currentTimeMillis() - t0 > 20 * 1000) {
cancel();
return;
}
try {
List phonesObject = (List) getAllPhonesMethod.invoke(callManagerObject);
Log.e(TAG, "All phones " + phonesObject + ", " + phonesObject.size());
List foregroundCalls = (List) getForegroundCallsMethod.invoke(callManagerObject);
Log.e(TAG, "Foreground calls: " + foregroundCalls + ", " + foregroundCalls.size());
Object backgroundCalls = getBackgroundCallsMethod.invoke(callManagerObject);
Log.e(TAG, "Background calls: " + backgroundCalls);
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.i(TAG, "New state: " + state);
} catch (Exception e) {
Log.e(TAG, ">>>1. " + e.getMessage());
}
}
};
timer.schedule(doAsynchronousTask, 0, 1000); //execute in every 1000 ms
} catch (ClassNotFoundException e) {
Log.e(TAG, ">>>2. " + e.getMessage());
} catch (NoSuchMethodException e) {
Log.e(TAG, ">>>3. " + e.getMessage());
} catch (InvocationTargetException e) {
Log.e(TAG, ">>>4. " + e.getMessage());
} catch (IllegalAccessException e) {
Log.e(TAG, ">>>5. " + e.getMessage());
}
}
}
但我得到了所有的背景/前景电话和emty结果:
08-03 15:19:22.638 2586 4636 E CallStatusPlugin: All phones [], 0
08-03 15:19:22.639 2586 4636 E CallStatusPlugin: Foreground calls: [], 0
08-03 15:19:22.639 2586 4636 E CallStatusPlugin: Background calls: []
不确定OS是否正在使用
呼叫管理器
或者不。
经过2-3周的研究,我了解到:
-
隐藏的API为我们提供了与OS更深入的集成(但是
Google may remove access to hidden API in Android P
)
-
Ringing sound of an outgoing call == Ringback tone
-
State dialing !== State of playing ringback tone
-
但是
我没有得出一个结论,我可以说,这是一种方式,我们可以得到的状态,一个传出的电话开始播放铃声
我通过读取所有操作系统日志
adb logcat '*:V'
当我听到铃声的时候看到一个日志正在打印(
adb logcat -b system '*:V'
):

然后我开始用谷歌搜索与
android io统计事件
&安培;
gsm连接事件
但我想不出任何方法来获得拨出电话的特定状态,即电话开始播放铃声。
我查看了各种Android代码,发现了一些提示:
-
TelephonyConnection
-
GsmConnection
有什么提示或方向可以帮助我实现这个目标吗?像GSM连接,
ConnectionService
,
ConnectivityManager
,
ConnectionService
或
ConnectionRequest
有什么事吗?
编辑1:
我读了更多的日志
SipManager
我读到了
SIP Basic Call Flow Examples
我想,Android是用来打电话或接电话的。
