我有利用ContentProvider和Asynctask救了我的数据到数据库SQLite问题的数据保存到SQLite的，这里是我的代码如何使用内容提供商和的AsyncTask
BtnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String JudulSesi = String.valueOf(judulSesi.getText());
String Description = String.valueOf(Ket.getText());
ContentValues contentValues = new ContentValues();
contentValues.put(LocalDBHandler.FIELD_SESSION_TYPE, sessionType);
contentValues.put(LocalDBHandler.FIELD_SESSION_NAME, JudulSesi);
contentValues.put(LocalDBHandler.FIELD_SESSION_DESC, Description);
contentValues.put(LocalDBHandler.FIELD_SESSION_TIME,Date.toString());
contentValues.put(LocalDBHandler.FIELD_ELAPSED_TIME, dataTimeElapsed);
contentValues.put(LocalDBHandler.FIELD_ARRAYPOINT,stringPoint);
contentValues.put(LocalDBHandler.FIELD_DISTANCE, dataJarak);
contentValues.put(LocalDBHandler.FIELD_SPEED, speed);
contentValues.put(LocalDBHandler.FIELD_HEART_RATE, heartRate);
contentValues.put(LocalDBHandler.FIELD_CALLORIES, callorie);
SaveToDatabase savetoDB = new SaveToDatabase();
savetoDB.execute(contentValues);
Toast.makeText(SaveSession.this, "You Click Save Button", Toast.LENGTH_SHORT).show();
}
});
private class SaveToDatabase extends AsyncTask<ContentValues,Void,Void>{
@Override
protected Void doInBackground(ContentValues... contentValues) {
getContentResolver().insert(Uri.parse(LocalDBHandler.DATABASE_TABLE),contentValues[0]);
return null;
}
}
当我运行我的程序，它的关闭，这里是logcat结果

它说我的Asynctask得到错误，但我不知道它在哪里。
