我遵循了示例中的代码(https://developers.google.com/fit/android/ble-sensors)但我得到了以下错误。
private void buildFitnessClient() {
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.API)
.addScope(FitnessScopes.SCOPE_ACTIVITY_READ)
.addScope(FitnessScopes.SCOPE_BODY_READ)
.addScope(FitnessScopes.SCOPE_LOCATION_READ)
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
buildBle(); // Scan for BLE Devices.
}
@Override
public void onConnectionSuspended(int i) {
// ..
}
}
)
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
// ..
}
)
.build();
}
private void buildBle() {
BleScanCallback callback = new BleScanCallback() {
@Override
public void onDeviceFound(BleDevice device) {
ClaimBleDeviceRequest request = new ClaimBleDeviceRequest.Builder()
.setDevice(device)
.build();
PendingResult<Status> pendingResult =
Fitness.BleApi.claimBleDevice(mClient, request);
}
@Override
public void onScanStopped() {
// ..
}
};
StartBleScanRequest request = new StartBleScanRequest.Builder()
.setDataTypes(DataTypes.HEART_RATE_BPM)
.setBleScanCallback(callback)
.build();
PendingResult<Status> pendingResult =
Fitness.BleApi.startBleScan(mClient, request);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// ..
buildFitnessClient();
}
调用buildBle()方法会出现以下错误。

请帮忙。谢谢
您应该在claimBleDevice调用中使用该设备。像这样：
BleScanCallback callback = new BleScanCallback() {
@Override
public void onDeviceFound(BleDevice device) {
PendingResult<Status> pendingResult =
Fitness.BleApi.claimBleDevice(mClient, device);
}
尝试将其添加到GoogleApiClient构建器：
.addApi(Fitness.BLE_API)
试试这个，
private BleScanCallback callback;
private void buildBle() {
callback = new BleScanCallback() {
@Override
public void onDeviceFound(BleDevice device) {
// ClaimBleDeviceRequest request = new ClaimBleDeviceRequest(mClient,device);
PendingResult<Status> pendingResult =
Fitness.BleApi.claimBleDevice(mClient, device);
}
@Override
public void onScanStopped() {
// ..
}
};
StartBleScanRequest request = new StartBleScanRequest.Builder()
.setDataTypes(DataType.TYPE_HEART_RATE_BPM)
.setBleScanCallback(callback)
.build();
PendingResult<Status> pendingResult =
Fitness.BleApi.startBleScan(mClient, request);
}
