我目前正試圖通過我的應用程序顯示今天的當前步驟。我有下面的代碼，其中大部分時間都是正確的。我也已將SHA1證書添加到開發者控制檯。Google fit history API不會檢索數據集？
我不斷收到錯誤「插入數據集時出現問題。」在我登錄之後，沒有其他的事情出現後，我有點困惑，爲什麼？
此外，這似乎是脾氣暴躁，有時它的工作原理和顯示隨機數7個數據集（不是我的步數），所以我的第二個問題是我如何才能讓它顯示在今天？

private void buildFitnessClient() {
if (mClient == null) {
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.HISTORY_API)
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
new InsertAndVerifyDataTask().execute();
}
@Override
public void onConnectionSuspended(int i) {
// If your connection to the sensor gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
Toast.makeText(getBaseContext(), "Connection lost. Cause: Network Lost.", Toast.LENGTH_LONG).show();
} else if (i
== GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG,
"Connection lost. Reason: Service Disconnected");
}
}
}
)
.enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Google Play services connection failed. Cause: " +
result.toString());
Toast.makeText(getBaseContext(), "Google Play services connection failed. Cause: " +

}
如果我認爲這個問題所在。
