这篇博客主要介绍了蓝牙文件传输的相关操作，包括设备选择界面的入口以及如何停止和隐藏传输界面。在停止传输的代码中，详细展示了传收状态、文件信息以及目标设备详情。

1）设备选择界面：com.android.settings/.bluetooth.DevicePickerActivity；

2）停止、隐藏传输界面：com.android.bluetooth/.opp.BluetoothOppTransferActivity

2.1）停止传输的代码：

 // "Stop" buttonthis.getContentResolver().delete(mUri, null, null);

 BluetoothTransferContentObserver 
 Intent intent = getIntent();
136        mUri = intent.getData();
137
138        mTransInfo = new BluetoothOppTransferInfo();
139        mTransInfo = BluetoothOppUtility.queryRecord(this, mUri);
public class BluetoothOppTransferInfo {
40    int mID;
41
42    int mDirection;
43
44    long mTotalBytes;
45
46    long mCurrentBytes;
47
48    int mStatus;
49
50    Long mTimeStamp;
51
52    String mDestAddr; // bt address
53
54    String mFileName;
55
56    String mFileType;
57
58    String mFileUri; // the uri of the transferring file, related to the URI
59
60    String mDeviceName; // bt device name
61
62    boolean mHandoverInitiated; // the transfer was initiated by connection handover (eg.           NFC)
63    // int mScanned;
64}
65

 mObserver = new BluetoothTransferContentObserver();
153            getContentResolver().registerContentObserver(BluetoothShare.CONTENT_URI, true,
154                    mObserver);

  public static final Uri CONTENT_URI = Uri.parse("content://com.android.bluetooth.opp/btopp");

mDirection：0，是传；1，是收；

{mID=27, mDirection=1, mTotalBytes=293837, mCurrentBytes=293837, mStatus=200, mTimeStamp=1528275867985, mDestAddr='90:F0:52:00:6F:03', mFileName='/storage/emulated/0/bluetooth/S80605-193537.jpg', mFileType='image/jpeg', mFileUri='content://media/external/images/media/994', mDeviceName='MEIZU PRO 6 Plus', mHandoverInitiated=false}
