android - Galaxy Tab2 は、HDPI または MDPI 解像度バケットの下にあります

Question

Galaxy Tab2 のアプリケーションを開発しています。画面解像度は 600*1024 (169 PPI) です。Android Documentによると、HDPI Android 解像度バケットに分類されます。このデバイスの最小幅は 600 PPI です。次に、1.50 で割ると 400 dp になります。したがって、その最小幅は 400 dp です。次に、sw-320dp フォルダーに移動します。しかし、実際には sw600dp にあるはずです。

だから私の疑いは、Tab2 id HDPI または MDPI ですか? または私は計算で何か間違いをしましたか？

私のコード:

public void calculate(View view)
    {
        EditText widthResolution=(EditText)findViewById(R.id.dip_et_screenwidthres);
        EditText heightResolution=(EditText)findViewById(R.id.dip_et_screenheightres);
        EditText size=(EditText)findViewById(R.id.dip_et_screensize);


        String screenWidth = widthResolution.getText().toString();
        Double screenWidthD=Double.valueOf(screenWidth);

        String screenHeight = heightResolution.getText().toString();
        Double screenHeightD=Double.valueOf(screenHeight);

        String screenSize = size.getText().toString();
        Double screenSizeD=Double.valueOf(screenSize);

        Double sumOfXY2=(screenWidthD*screenWidthD)+(screenHeightD*screenHeightD);
        double totalDiagonalRes = Math.sqrt(sumOfXY2);

        Double diagonalPPI =totalDiagonalRes/screenSizeD;

        //used for calculation
        int diagonalPPIInt=diagonalPPI.intValue();
