End call in android programmatically
For Android P (since Beta 2) and above, there is finally a formal API for endCall:
https://developer.android.com/reference/android/telecom/TelecomManager#endCall()
The ANSWER_PHONE_CALLS
permission is required in manifest:
<uses-permission android:name="android.permission.ANSWER_PHONE_CALLS" />
With the permission, for API level 28 or above:
TelecomManager tm = (TelecomManager) mContext.getSystemService(Context.TELECOM_SERVICE);
if (tm != null) {
boolean success = tm.endCall();
// success == true if call was terminated.
}
At the same time the original endCall()
method under TelephonyManager
is now protected by MODIFY_PHONE_STATE
permission, and can no longer be invoked by non-system Apps by reflection without the permission (otherwise a Security Exception will be triggered).
You do not need to be a system app. First, create package com.android.internal.telephony
in your project, and put this in a file called "ITelephony.aidl
":
package com.android.internal.telephony;
interface ITelephony {
boolean endCall();
void answerRingingCall();
void silenceRinger();
}
Once you have that, you can use this code to end a call:
TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
Class clazz = Class.forName(telephonyManager.getClass().getName());
Method method = clazz.getDeclaredMethod("getITelephony");
method.setAccessible(true);
ITelephony telephonyService = (ITelephony) method.invoke(telephonyManager);
telephonyService.endCall();
You could use this inside a PhoneStateListener, for example. For this to work, you require permissions in manifest:
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
Edit: Apologies for horrible formatting, I still can't figure out how to properly do code blocks here :/
