AsyncTask callbacks and threads in Android: excerpt from page 43 of the BCA 318T notes

BCA 318T exam corner: 65 two-mark and 43 ten-mark exam questions by unit

Each unit ends with questions labelled "2 Marks" and "10 Marks", matching the end-term paper.

• Unit 1, 10 Marks: Explain how to receive and broadcast intents using Broadcast Receivers (static and dynamic). Pointer: page 17, the onReceive() class and the static vs dynamic table.
• Unit 2, 2 Marks: Differentiate Toast and Snackbar. Pointer: a Snackbar sits in the app and can carry one action such as UNDO; a Toast has none (page 38).
• Unit 3, 2 Marks: What is the Fused Location Provider? Pointer: it mixes GPS, Wi-Fi and cell data for the best accuracy at low battery cost (page 52).
• Unit 4, 10 Marks: Write a program for insert, update, delete and select using SQLiteOpenHelper. Pointer: the DBHelper class on page 63.

The BCA 318T notes list 65 two-mark and 43 ten-mark exam questions across 4 units, plus 73 code listings.

These GGSIPU BCA Sem 6 Mobile Application Development notes follow the BCA scheme for the 2024-25 batch onwards. The 2026-27 edition marks where Android has moved on from the syllabus names: AsyncTask deprecated in API 30, Loaders in API 28, Android 14 foreground service types and Material 3. Read our editorial policy.

The same team prepares GGSIPU important questions for every course.

Do the BCA 318T notes cover the full GGSIPU syllabus?

Yes. Every topic in the four official BCA 318T units has its own section in the notes; the unit check found no gap.

Official sources: BCA Scheme of Examination & Syllabi, batch 2024-25 onwards (2026) and the BCA scheme of examination, w.e.f. 2024-25.

Every course in GGSIPU notes is mapped to its official PDF the same way.

How to write BCA 318T answers: lifecycle diagrams, code-backed ten-mark answers and two-mark comparisons

Two-mark answers need a definition plus one difference or example; ten-mark answers need a diagram or table, method names and short code. The notes' exam tips show what each long answer carries:

• Activity lifecycle (page 15): draw the flow, write all 7 methods with one line each, name the 4 states and the back stack, end with the Logcat demo, and call super.onXxx() first.
• Layouts (page 24): a small box sketch per layout, 3 key attributes each, and one line that ConstraintLayout is the default because it avoids deep nesting.
• Fragment life cycle (page 33): the 11 callbacks from onAttach() to onDetach(), the flow, and the Activity vs Fragment table.
• Maps and Places (page 55): one line on restricting the API key to the package name and SHA-1 fingerprint.
• SQLite (page 64): ? placeholders with selection arguments instead of joined user input, plus transactions for bulk inserts.

Two mistakes the notes warn about: hard-coding text in Java instead of strings.xml, and running network or database work on the main thread, which brings an ANR after about 5 seconds. Practise this format on GGSIPU BCA important questions.

BCA 318T and the BCA 318P Mobile Application Development lab, plus other GGSIPU BCA Sem 6 papers

The official PDF leaves the BCA 318P practical list to the teacher, who notifies it in the first week. The code to rehearse is already here, from intents in Unit 1 to SQLite in Unit 4. These Mobile Application Development notes in English use the same Java and XML you type in the lab.

Taking BCA 318T means skipping the other electives: BCA 312T Data Visualization & Analytics, BCA 314T Deep Learning with Python and BCA 316T Web Security. Everyone takes BCA 302T Distributed systems and Cloud Computing, BCA 304T Machine Learning, BCA 306T Software Project Management and BCA 320 Minor Project.
