[Android] I want to make QA easier ... That's right! Let's make a debug menu!

What is a debug menu?

Hidden features for software developers. Since it is a function for developers only, it is standard that general users cannot operate it.

Do you need it?

It's not a mast. It's just to make debugging easier, so let's start by hearing from the person who debugs. However, if there is a voice saying that it would be nice to have it, or if debugging requires man-hours for engineers, it is better to make it.

Implemented function example

View & copy

• Build Ver.
• HOSTNAME (switching server host)
• AdID etc...

action

• IMAGE CACHE Deleted (Glide)
• Delete all data
• Change date (reset)
• Test user for external cooperation
• Authentication from external access
• Withdrawal etc...

Implementation example

This is an item cell sample. I think it's okay for parents to enclose it in ScrollView and multiply it.

It's just a dividing line.

component_divider_wrap.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/div"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="72dp"
        android:layout_weight="1">

        <View style="@style/divider_horizontal"/>

    </LinearLayout>
</merge>

An example is described in onCreate as a sample, but it becomes difficult to read as the number of items increases, so it may be good to bind items with Butter Knife.

DebugMenuActivity.java

public class DebugMenuActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_debug_menu);
        
        // Build Ver. Text
        TextView buildInfoTxt = (TextView)findViewById(R.id.build_info_txt);
        
        buildInfoTxt.setText("Ver. " + BuildConfig.VERSION_NAME + " " + BuildConfig.BUILD_TIMESTAMP + " " + BuildConfig.BUILD_HASH + " (" + BuildConfig.BUILD_MACHINE + ")");
        // Build Ver. Area
　　　　LinearLayout buildInfoArea =(LinearLayout)findViewById(R.id.build_info_area);
        
        buildInfoArea.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                copyClipBoard((String)buildInfoTxt.getText());
            }
        });
    }

   //Copy to clipboard
   private void copyClipBoard(String copySource) {
        if (copySource.equals("")) {
            return;
        }
 
        //Create an Item to store in the clipboard
        ClipData.Item item = new ClipData.Item(copySource);

        //Creating a MIME TYPE
        String[] mimeType = new String[1];
        mimeType[0] = ClipDescription.MIMETYPE_TEXT_URILIST;

        //Creating a ClipData object to store in the clipboard
        ClipData cd = new ClipData(new ClipDescription("text_data", mimeType), item);

        //Store data in clipboard
        ClipboardManager cm = (ClipboardManager) getActivity().getSystemService(Context.CLIPBOARD_SERVICE);
        cm.setPrimaryClip(cd);
    }
}

If you add a function that gives a suggestion when you tap the icon when changing the Host Name with self-satisfaction, it is surprisingly popular, or if you implement it because it is better to be able to authenticate external access, Pl will ** give me yakiniku Was ** ** Athlete engineers who like yakiniku!
