How to determine whether the phone was hung up locally or was hung up by the remote end?

Question

When an incoming call hangs up, how do you judge whether to hang up or hang up? How do I monitor the hangup button on the phone page? If you know the answer, please tell me, thank you！

In my opinion, you can NOT do this.

But looking into DisconnectCause (android.telecom.DisconnectCause), maybe here has some help.

/** Disconnected because of an unknown or unspecified reason. */
public static final int UNKNOWN = 0;
/** Disconnected because there was an error, such as a problem with the network. */
public static final int ERROR = 1;
/** Disconnected because of a local user-initiated action, such as hanging up. */
public static final int LOCAL = 2;
/**
 * Disconnected because of a remote user-initiated action, such as the other party hanging up
 * up.
 */
public static final int REMOTE = 3;
/** Disconnected because it has been canceled. */
public static final int CANCELED = 4;
/** Disconnected because there was no response to an incoming call. */
public static final int MISSED = 5;
/** Disconnected because the user rejected an incoming call. */
public static final int REJECTED = 6;
/** Disconnected because the other party was busy. */
public static final int BUSY = 7;
/**
 * Disconnected because of a restriction on placing the call, such as dialing in airplane
 * mode.
 */
public static final int RESTRICTED = 8;
/** Disconnected for reason not described by other disconnect codes. */
public static final int OTHER = 9;

Sure there are much more reasons than local or remote hang-up.

Looking into android.telecom.ConnectionService, maybe some hack way can achieve your target.

Good luck.
