A.通话是否具有视频功能   mCallLogCache.isVideoEnabled()

packages\apps\Dialer\src\com\android\dialer\calllog\calllogcache\CallLogCache.java

mIsVideoEnabled = CallUtil.isVideoEnabled(mContext);  import com.android.contacts.common.CallUtil;

?

1 2 3 4 5 6 7

public boolean isVideoEnabled() {     if (!mHasCheckedForVideoEnabled) {         mIsVideoEnabled = CallUtil.isVideoEnabled(mContext);         mHasCheckedForVideoEnabled = true;     }     return mIsVideoEnabled; }

packages\apps\ContactsCommon\src\com\android\contacts\common\CallUtil.java

/**
* Indicates that the video calling is not available.
*/
public static final int VIDEO_CALLING_DISABLED = 0;

/**
* Indicates that video calling is enabled, regardless of presence status.
*/
public static final int VIDEO_CALLING_ENABLED = 1;

getVideoCallingAvailability 看支不支持 video_calling 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

public static boolean isVideoEnabled(Context context) {     return (getVideoCallingAvailability(context) & VIDEO_CALLING_ENABLED) != 0; }     public static int getVideoCallingAvailability(Context context) {     if (!PermissionsUtil.hasPermission(context, android.Manifest.permission.READ_PHONE_STATE)             || !CompatUtils.isVideoCompatible()) {         return VIDEO_CALLING_DISABLED;     }     TelecomManager telecommMgr = (TelecomManager)             context.getSystemService(Context.TELECOM_SERVICE);     if (telecommMgr == null) {         return VIDEO_CALLING_DISABLED;     }       List<PhoneAccountHandle> accountHandles = telecommMgr.getCallCapablePhoneAccounts();     for (PhoneAccountHandle accountHandle : accountHandles) {         PhoneAccount account = telecommMgr.getPhoneAccount(accountHandle);         if (account != null) {             if (account.hasCapabilities(PhoneAccount.CAPABILITY_VIDEO_CALLING)) {//能够视频通话的标志                 // Builds prior to N do not have presence support.                 if (!CompatUtils.isVideoPresenceCompatible()) {                     return VIDEO_CALLING_ENABLED;                 }                   int videoCapabilities = VIDEO_CALLING_ENABLED;                 if (account.hasCapabilities(                         PhoneAccountSdkCompat.CAPABILITY_VIDEO_CALLING_RELIES_ON_PRESENCE)) {//列表示是否联系人的电话号码支持视频通话                     videoCapabilities |= VIDEO_CALLING_PRESENCE;                 }                 return videoCapabilities;             }         }     }     return VIDEO_CALLING_DISABLED;//以上条件均不满足 最后就会返回VIDEO_CALLING_DISABLED 0 }

frameworks\base\telecomm\java\android\telecom\PhoneAccount.java

Android 8.0 PhoneAccount全面解析 PhoneAccount这个类是关于SIM卡信息的

PhoneAccount account = telecommMgr.getPhoneAccount(accountHandle);

account.hasCapabilities(PhoneAccount.CAPABILITY_VIDEO_CALLING)  

account.hasCapabilities(PhoneAccountSdkCompat.CAPABILITY_VIDEO_CALLING_RELIES_ON_PRESENCE)

 

B.添加拨号的intent  videoCallButtonView.setTag(IntentProvider.getReturnVideoCallIntentProvider(number));

b.1. packages\apps\Dialer\src\com\android\dialer\calllog\IntentProvider.java

主要看 new IntentProvider() 类中 getIntent 方法

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

public static IntentProvider getReturnVideoCallIntentProvider(final String number) {     return getReturnVideoCallIntentProvider(number, null); }   public static IntentProvider getReturnVideoCallIntentProvider(final String number,         final PhoneAccountHandle accountHandle) {     return new IntentProvider() {         @Override         public Intent getIntent(Context context) {             return new CallIntentBuilder(number)                     .setPhoneAccountHandle(accountHandle)                     .setCallInitiationType(LogState.INITIATION_CALL_LOG)                     .setIsVideoCall(true)                     .build();         }     }; }

public abstract Intent getIntent(Context context);

没想到IntentProvider 也是个抽象类  public abstract class IntentProvider  {

b.2. packages\apps\Dialer\src\com\android\dialer\util\IntentUtil.java   构建intent   // 普通电话为VideoProfile.STATE_AUDIO_ONLY

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

public static class CallIntentBuilder {     private Uri mUri;     private int mCallInitiationType;     private PhoneAccountHandle mPhoneAccountHandle;     private boolean mIsVideoCall = false;    ……     public Intent build() {         return getCallIntent(                 mUri,                 mPhoneAccountHandle,                 mIsVideoCall ? VideoProfile.STATE_BIDIRECTIONAL : VideoProfile.STATE_AUDIO_ONLY,                 mCallInitiationType);     } }

1.4.按钮监听事件 走 else startActivityWithErrorToast

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

@Override public void onClick(View view) {     if (view.getId() == R.id.primary_action_button && !TextUtils.isEmpty(voicemailUri)) {         mVoicemailPrimaryActionButtonClicked = true;         mExpandCollapseListener.onClick(primaryActionView);     } else if (view.getId() == R.id.call_with_note_action) {         CallSubjectDialog.start(                 (Activity) mContext,                 info.photoId,                 info.photoUri,                 info.lookupUri,                 (String) nameOrNumber /* top line of contact view in call subject dialog */,                 isBusiness,                 number,                 TextUtils.isEmpty(info.name) ? null : displayNumber, /* second line of contact                                                                        view in dialog. */                 numberType, /* phone number type (e.g. mobile) in second line of contact view */                 accountHandle);     } else {         final IntentProvider intentProvider = (IntentProvider) view.getTag();         if (intentProvider != null) {             final Intent intent = intentProvider.getIntent(mContext);             // See IntentProvider.getCallDetailIntentProvider() for why this may be null.             if (intent != null) {                 DialerUtils.startActivityWithErrorToast(mContext, intent);             }         }     } }

1.5.packages\apps\Dialer\src\com\android\dialer\util\DialerUtils.java

 intent.getAction()->android.intent.action.CALL　处理拨号

public static void startActivityWithErrorToast(Context context, Intent intent, int msgId) {     try {         if ((IntentUtil.CALL_ACTION.equals(intent.getAction())                         && context instanceof Activity)) {             // All dialer-initiated calls should pass the touch point to the InCallUI             Point touchPoint = TouchPointManager.getInstance().getPoint();             if (touchPoint.x != 0 || touchPoint.y != 0) {                 Bundle extras;                 // Make sure to not accidentally clobber any existing extras                 if (intent.hasExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS)) {                     extras = intent.getParcelableExtra(                             TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS);                 } else {                     extras = new Bundle();                 }                 extras.putParcelable(TouchPointManager.TOUCH_POINT, touchPoint);                 intent.putExtra(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS, extras);             }               final boolean hasCallPermission = TelecomUtil.placeCall((Activity) context, intent);             if (!hasCallPermission) {                 // TODO: Make calling activity show request permission dialog and handle                 // callback results appropriately.                 Toast.makeText(context, "Cannot place call without Phone permission",                         Toast.LENGTH_SHORT);             }         } else {             context.startActivity(intent);         }     } catch (ActivityNotFoundException e) {         Toast.makeText(context, msgId, Toast.LENGTH_SHORT).show();     } }
