Google適合API、onDatapointメソッドが呼び出されていません

Question

ステップカウントを取得できません。私はonDataPointメソッドを呼び出すことに固執しています。このコードはほぼ正しいです。私はステップカウントが表示されていない理由を見つけることができません。

Answer 1

（コメントで解くように）問題がTYPE_STEP_COUNT_CUMULATIVEがGoogle uses a combination of sensors, accelerometer, machine learning, etc. to determine step countタイプ - 生データではないということです。したがって、.setDataSourceTypes(DataSource.TYPE_RAW)行を削除する必要があります。

OPは、行を削除するだけでは、DataSource.TYPE_DERIVEDに置き換えるよりも正確さが劣ることに気付きました。

また、Google Fit FAQは、TYPE_DERIVEDを使用する例があります。
