[移动开发]android蓝牙同步通讯录

代码来源　Pie 9.0.0_r3

通讯录存放在哪？

系统有个apk叫

ContactsProvider
里面有如下数据库，通讯录就存在数据库里
/data/data/com.android.providers.contacts/databases/calllog.db
/data/data/com.android.providers.contacts/databases/contacts2.db
/data/data/com.android.providers.contacts/databases/profile.db

谁去管理同步过程？

蓝牙电话同步通讯录时会去操作ContactsProvider
PhonebookPullRequest.java

Handler接收消息进行同步
PbapClientConnectionHandler.java

241            case MSG_DOWNLOAD:
242                try {
243                    mAccountCreated = addAccount(mAccount);
244                    if (!mAccountCreated) {
245                        Log.e(TAG, "Account creation failed.");
246                        return;
247                    }
248                    // Start at contact 1 to exclued Owner Card PBAP 1.1 sec 3.1.5.2
249                    BluetoothPbapRequestPullPhoneBook request =
250                            new BluetoothPbapRequestPullPhoneBook(PB_PATH, mAccount,
251                                    PBAP_REQUESTED_FIELDS, VCARD_TYPE_30, 0, 1);
252                    request.execute(mObexSession);
253                    PhonebookPullRequest processor =
254                            new PhonebookPullRequest(mPbapClientStateMachine.getContext(),
255                                    mAccount);
256                    processor.setResults(request.getList());
257                    processor.onPullComplete();
258                    HashMap<String, Integer> callCounter = new HashMap<>();
259                    downloadCallLog(MCH_PATH, callCounter);
260                    downloadCallLog(ICH_PATH, callCounter);
261                    downloadCallLog(OCH_PATH, callCounter);
262                } catch (IOException e) {
263                    Log.w(TAG, "DOWNLOAD_CONTACTS Failure" + e.toString());
264                }

哪里发送的消息呢？
1.连接上PBAP后已经解除锁屏
PbapClientStateMachine.java

295    class Connected extends State {
296        @Override
297        public void enter() {
298            Log.d(TAG, "Enter Connected: " + getCurrentMessage().what);
299            onConnectionStateChanged(mCurrentDevice, mMostRecentState,
300                    BluetoothProfile.STATE_CONNECTED);
301            mMostRecentState = BluetoothProfile.STATE_CONNECTED;
302            if (mUserManager.isUserUnlocked()) {
303                mConnectionHandler.obtainMessage(PbapClientConnectionHandler.MSG_DOWNLOAD)
304                        .sendToTarget();
305            }
306        }

2.收到解除锁屏广播后会调用　resumeDownload

356    public void resumeDownload() {
357        sendMessage(MSG_RESUME_DOWNLOAD);
358    }
==========================
321                case MSG_RESUME_DOWNLOAD:
322                    mConnectionHandler.obtainMessage(PbapClientConnectionHandler.MSG_DOWNLOAD)
323                            .sendToTarget();
324                    break;
