Android method missing: ScanRecord.parseFromBytes

I searched the source code for android 22 to change my code to a new BLE scan and came across a ScanRecord class. When I opened the source code for ScanRecord (sources / android-22 / android / bluetooth / le / ScanRecord.java), I saw that the parseFromBytes function exists:

/** * Parse scan record bytes to {@link ScanRecord}. * <p> * The format is defined in Bluetooth 4.1 specification, Volume 3, Part C, Section 11 and 18. * <p> * All numerical multi-byte entities and values shall use little-endian <strong>byte</strong> * order. * * @param scanRecord The scan record of Bluetooth LE advertisement and/or scan response. * @hide */ public static ScanRecord parseFromBytes(byte[] scanRecord)

But if I try to use it in my code, he will not be able to find this function. Also, if I check the API here , the function is not mentioned at all.

I am using Android Studio 1.3.1 with compileSdkVersion 22, minSdkVersion 18, targetSdkVersion 22 and buildToolsVersion 22.0.1

What am I missing? Why can't I use this function, although it is part of the Android source code?

Thanks for clarifying.

The ScanRecord class has been added to the Level 21 API. You can get an instance of it from ScanResult Code:

 ScanCallback leScanCallback = new ScanCallback() { @Override public void onScanResult(int callbackType, ScanResult result) { ScanRecord record = result.getScanRecord(); } }

Public functions are available in this instance of the object.

I had the same problem and wanted to use ScanRecord.parseFromBytes. After many searches, I noticed that it has a "@hide" tag that effectively hides it from the compiler. See What does @hide mean in Android source code?

I'm in two minds to use reflection, but I want to access the fields in ScanRecord (e.g. TxPower)
