### Launch Database Manager from TextView Click

Source: https://github.com/sanathp/databasemanager_for_android/blob/master/README.md

Implement an OnClickListener for a TextView to programmatically start the AndroidDatabaseManager activity. This method provides a simple way to integrate the database management interface into your application's user interface, allowing users to access it via a text element.

```Java
TextView tv =(TextView)findViewById(R.id.yourtextviewid);

tv.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {

      Intent dbmanager = new Intent(getActivity(),AndroidDatabaseManager.class);
        startActivity(dbmanager);
         }
    });
```

### Launch Database Manager from Button Click

Source: https://github.com/sanathp/databasemanager_for_android/blob/master/README.md

Attach an OnClickListener to a Button to initiate the AndroidDatabaseManager activity. This approach offers a common and intuitive user interface element for launching the database manager, providing easy access for developers during the app's development phase.

```Java
Button button =(Button)findViewByID(R.id.yourbuttonid);

button.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {

      Intent dbmanager = new Intent(getActivity(),AndroidDatabaseManager.class);
        startActivity(dbmanager);
         }
    });
```

### Declare AndroidDatabaseManager Activity in Manifest

Source: https://github.com/sanathp/databasemanager_for_android/blob/master/README.md

Add this activity declaration to your AndroidManifest.xml file. Replace 'yourpackagename' with the actual package where AndroidDatabaseManager.java is located. This ensures the activity is registered and can be launched within your Android application.

```XML
<activity android:name="yourpackagename.AndroidDatabaseManager" 
    android:theme="@style/Theme.AppCompat.Light"/>
```

### Execute Raw SQL Query on Android SQLite Database

Source: https://github.com/sanathp/databasemanager_for_android/blob/master/helperFunction.txt

This Java method, `getData`, takes a SQL query string as input and executes it against the writable SQLite database. It returns an `ArrayList` containing two `Cursor` objects: one for query results (if successful) and another for status/error messages. It includes error handling for `SQLException` and general `Exception`, logging errors and returning them via the second Cursor.

```Java
public ArrayList<Cursor> getData(String Query){
	//get writable database
	SQLiteDatabase sqlDB = this.getWritableDatabase();
	String[] columns = new String[] { "message" };
	//an array list of cursor to save two cursors one has results from the query 
	//other cursor stores error message if any errors are triggered
	ArrayList<Cursor> alc = new ArrayList<Cursor>(2);
	MatrixCursor Cursor2= new MatrixCursor(columns);
	alc.add(null);
	alc.add(null);
	
	try{
		String maxQuery = Query ;
		//execute the query results will be save in Cursor c
		Cursor c = sqlDB.rawQuery(maxQuery, null);

		//add value to cursor2
		Cursor2.addRow(new Object[] { "Success" });
		
		alc.set(1,Cursor2);
		if (null != c && c.getCount() > 0) {

			alc.set(0,c);
			c.moveToFirst();
			
			return alc ;
		}
		return alc;
	} catch(SQLException sqlEx){
		Log.d("printing exception", sqlEx.getMessage());
		//if any exceptions are triggered save the error message to cursor an return the arraylist
		Cursor2.addRow(new Object[] { ""+sqlEx.getMessage() });
		alc.set(1,Cursor2);
		return alc;
	} catch(Exception ex){
		Log.d("printing exception", ex.getMessage());

		//if any exceptions are triggered save the error message to cursor an return the arraylist
		Cursor2.addRow(new Object[] { ""+ex.getMessage() });
		alc.set(1,Cursor2);
		return alc;
	}
}
```
