我正在开发一个应用程序,其中我们需要的一件事就是控制传出呼叫,至少能够从我们的应用程序中阻止它。
我尝试使用现有活动中的Intent.ACTION_CALL
:
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
startActivity(callIntent);
但是通过API似乎不允许停止呼叫。
你能建议一些解决方法吗?
例如:在通话期间启用飞机模式?只是一个例子;这个黑客对我不起作用。

已经提到在BroadcastReceiver
中捕获拨出电话,如果您想在拨号前结束通话,这绝对是最好的方式。
然而,一旦拨号或通话,该技术就不再适用。我到目前为止挂断的唯一方法是通过Java Reflection这样做。由于它不是公共API的一部分,因此您应该小心使用它,而不是依赖它。对Android内部组成的任何更改都将有效地破坏您的应用程序。
Prasanta Paul's blog demonstrates如何实现,我在下面进行了总结。
获取ITelephony
对象:
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
try {
// Java reflection to gain access to TelephonyManager's
// ITelephony getter
Log.v(TAG, "Get getTeleService...");
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
com.android.internal.telephony.ITelephony telephonyService =
(ITelephony) m.invoke(tm);
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG,
"FATAL ERROR: could not connect to telephony subsystem");
Log.e(TAG, "Exception object: " + e);
}
结束通话:
telephonyService.endCall();

试试这个:
(我使用了Reflection to access advanced telephony features并修改了某些内容)
// required permission <uses-permission android:name="android.permission.CALL_PHONE"/>
try {
//String serviceManagerName = "android.os.IServiceManager";
String serviceManagerName = "android.os.ServiceManager";
String serviceManagerNativeName = "android.os.ServiceManagerNative";
String telephonyName = "com.android.internal.telephony.ITelephony";
Class telephonyClass;
Class telephonyStubClass;
Class serviceManagerClass;
Class serviceManagerStubClass;
Class serviceManagerNativeClass;
Class serviceManagerNativeStubClass;
Method telephonyCall;
Method telephonyEndCall;
Method telephonyAnswerCall;
Method getDefault;
Method[] temps;
Constructor[] serviceManagerConstructor;
// Method getService;
Object telephonyObject;
Object serviceManagerObject;
telephonyClass = Class.forName(telephonyName);
telephonyStubClass = telephonyClass.getClasses()[0];
serviceManagerClass = Class.forName(serviceManagerName);
serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
Method getService = // getDefaults[29];
serviceManagerClass.getMethod("getService", String.class);
Method tempInterfaceMethod = serviceManagerNativeClass.getMethod(
"asInterface", IBinder.class);
Binder tmpBinder = new Binder();
tmpBinder.attachInterface(null, "fake");
serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
telephonyObject = serviceMethod.invoke(null, retbinder);
//telephonyCall = telephonyClass.getMethod("call", String.class);
telephonyEndCall = telephonyClass.getMethod("endCall");
//telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
telephonyEndCall.invoke(telephonyObject);
} catch (Exception e) {
e.printStackTrace();
Log.error(DialerActivity.this,
"FATAL ERROR: could not connect to telephony subsystem");
Log.error(DialerActivity.this, "Exception object: " + e);
}

BroadcastReceiver
。ACTION_NEW_OUTGOING_CALL
方法onReceive
意图
setResultData(null)
这会阻止呼叫发起(只要你的接收者是最后一个处理我认为的意图)
答案 3 :(得分:5)
您可以尝试启用然后禁用飞行模式:
android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.AIRPLANE_MODE_ON, 1);
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", 1);
sendBroadcast(new Intent("android.intent.action.AIRPLANE_MODE"));
sendBroadcast(intent);
android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.AIRPLANE_MODE_ON, 0);
intent.putExtra("state", 0);
sendBroadcast(new Intent("android.intent.action.AIRPLANE_MODE"));
sendBroadcast(intent);

对于Ilana:
public class ilanasReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
if (getResultData()!=null) {
String number = "123456";
setResultData(number);
}
}
}
}
另外在Manifest中放入包部分:
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
就是这样。

这是最新的代码,它也适用于Android P,因为它具有正式的API(here):
在清单中,添加以下内容:
hts
在代码中,使用此:
Java:
<uses-permission android:name="android.permission.ANSWER_PHONE_CALLS"/>
或在科特林:
@SuppressLint("PrivateApi")
public static boolean endCall(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
final TelecomManager telecomManager = (TelecomManager) context.getSystemService(Context.TELECOM_SERVICE);
if (telecomManager != null && ContextCompat.checkSelfPermission(context, Manifest.permission.ANSWER_PHONE_CALLS) == PackageManager.PERMISSION_GRANTED) {
telecomManager.endCall();
return true;
}
return false;
}
//use unofficial API for older Android versions, as written here: https://stackoverflow.com/a/8380418/878126
try {
final Class<?> telephonyClass = Class.forName("com.android.internal.telephony.ITelephony");
final Class<?> telephonyStubClass = telephonyClass.getClasses()[0];
final Class<?> serviceManagerClass = Class.forName("android.os.ServiceManager");
final Class<?> serviceManagerNativeClass = Class.forName("android.os.ServiceManagerNative");
final Method getService = serviceManagerClass.getMethod("getService", String.class);
final Method tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder.class);
final Binder tmpBinder = new Binder();
tmpBinder.attachInterface(null, "fake");
final Object serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
final IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
final Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
final Object telephonyObject = serviceMethod.invoke(null, retbinder);
final Method telephonyEndCall = telephonyClass.getMethod("endCall");
telephonyEndCall.invoke(telephonyObject);
return true;
} catch (Exception e) {
e.printStackTrace();
LogManager.e(e);
}
return false;
}

考虑到可能出现的恶作剧,如果允许,我会感到惊讶。
这个帖子断然说the API cannot end a call。其他have tried。
答案 7 :(得分:0)
根据ACTION_NEW_OUTGOING_CALL
的文件
意图将具有以下额外值:
EXTRA_PHONE_NUMBER - 最初打算拨打的电话号码。
广播完成后,resultData将用作要调用的实际号码。如果为null,则不会进行任何调用。
