The 238 | following considerations are for informational purposes only, are not 239 | exhaustive, and do not form part of our licenses. 240 | 241 | Considerations for licensors: Our public licenses are 242 | intended for use by those authorized to give the public 243 | permission to use material in ways otherwise restricted by 244 | copyright and certain other rights. Our licenses are 245 | irrevocable. Licensors should read and understand the terms 246 | and conditions of the license they choose before applying it. 247 | Licensors should also secure all rights necessary before 248 | applying our licenses so that the public can reuse the 249 | material as expected. Licensors should clearly mark any 250 | material not subject to the license. This includes other CC- 251 | licensed material, or material used under an exception or 252 | limitation to copyright. More considerations for licensors: 253 | wiki.creativecommons.org/Considerations_for_licensors 254 | 255 | Considerations for the public: By using one of our public 256 | licenses, a licensor grants the public permission to use the 257 | licensed material under specified terms and conditions. If 258 | the licensor's permission is not necessary for any reason--for 259 | example, because of any applicable exception or limitation to 260 | copyright--then that use is not regulated by the license. Our 261 | licenses grant only permissions under copyright and certain 262 | other rights that a licensor has authority to grant. Use of 263 | the licensed material may still be restricted for other 264 | reasons, including because others have copyright or other 265 | rights in the material. A licensor may make special requests, 266 | such as asking that all changes be marked or described. 267 | Although not required by our licenses, you are encouraged to 268 | respect those requests where reasonable.

To the 279 | extent this Public License may be interpreted as a contract, You are 280 | granted the Licensed Rights in consideration of Your acceptance of 281 | these terms and conditions, and the Licensor grants You such rights in 282 | consideration of benefits the Licensor receives from making the 283 | Licensed Material available under these terms and conditions. 284 | 285 | 286 | Section 1 -- Definitions. 287 | 288 | a. Adapted Material means material subject to Copyright and Similar 289 | Rights that is derived from or based upon the Licensed Material 290 | and in which the Licensed Material is translated, altered, 291 | arranged, transformed, or otherwise modified in a manner requiring 292 | permission under the Copyright and Similar Rights held by the 293 | Licensor. For purposes of this Public License, where the Licensed 294 | Material is a musical work, performance, or sound recording, 295 | Adapted Material is always produced where the Licensed Material is 296 | synched in timed relation with a moving image. 297 | 298 | b.

Effective Technological Measures means those measures that, in the 311 | absence of proper authority, may not be circumvented under laws 312 | fulfilling obligations under Article 11 of the WIPO Copyright 313 | Treaty adopted on December 20, 1996, and/or similar international 314 | agreements. 315 | 316 | e. Exceptions and Limitations means fair use, fair dealing, and/or 317 | any other exception or limitation to Copyright and Similar Rights 318 | that applies to Your use of the Licensed Material. 319 | 320 | f. Licensed Material means the artistic or literary work, database, 321 | or other material to which the Licensor applied this Public 322 | License. 323 | 324 | g.

Licensor means the individual(s) or entity(ies) granting rights 330 | under this Public License. 331 | 332 | i. Share means to provide material to the public by any means or 333 | process that requires permission under the Licensed Rights, such 334 | as reproduction, public display, public performance, distribution, 335 | dissemination, communication, or importation, and to make material 336 | available to the public including in ways that members of the 337 | public may access the material from a place and at a time 338 | individually chosen by them. 339 | 340 | j. Sui Generis Database Rights means rights other than copyright 341 | resulting from Directive 96/9/EC of the European Parliament and of 342 | the Council of 11 March 1996 on the legal protection of databases, 343 | as amended and/or succeeded, as well as other essentially 344 | equivalent rights anywhere in the world. 345 | 346 | k. You means the individual or entity exercising the Licensed Rights 347 | under this Public License. Your has a corresponding meaning. 348 | 349 | 350 | Section 2 -- Scope. 351 | 352 | a. License grant. 353 | 354 | 1. Subject to the terms and conditions of this Public License, 355 | the Licensor hereby grants You a worldwide, royalty-free, 356 | non-sublicensable, non-exclusive, irrevocable license to 357 | exercise the Licensed Rights in the Licensed Material to: 358 | 359 | a. reproduce and Share the Licensed Material, in whole or 360 | in part; and 361 | 362 | b. produce, reproduce, and Share Adapted Material. 363 | 364 | 2. Exceptions and Limitations. For the avoidance of doubt, where 365 | Exceptions and Limitations apply to Your use, this Public 366 | License does not apply, and You do not need to comply with 367 | its terms and conditions. 368 | 369 | 3. Term. The term of this Public License is specified in Section 370 | 6(a). 371 | 372 | 4. Media and formats; technical modifications allowed. The 373 | Licensor authorizes You to exercise the Licensed Rights in 374 | all media and formats whether now known or hereafter created, 375 | and to make technical modifications necessary to do so. The 376 | Licensor waives and/or agrees not to assert any right or 377 | authority to forbid You from making technical modifications 378 | necessary to exercise the Licensed Rights, including 379 | technical modifications necessary to circumvent Effective 380 | Technological Measures. For purposes of this Public License, 381 | simply making modifications authorized by this Section 2(a) 382 | (4) never produces Adapted Material. 383 | 384 | 5. Downstream recipients. 385 | 386 | a. Offer from the Licensor -- Licensed Material. Every 387 | recipient of the Licensed Material automatically 388 | receives an offer from the Licensor to exercise the 389 | Licensed Rights under the terms and conditions of this 390 | Public License. 391 | 392 | b. No downstream restrictions. You may not offer or impose 393 | any additional or different terms or conditions on, or 394 | apply any Effective Technological Measures to, the 395 | Licensed Material if doing so restricts exercise of the 396 | Licensed Rights by any recipient of the Licensed 397 | Material. 398 | 399 | 6. No endorsement. Nothing in this Public License constitutes or 400 | may be construed as permission to assert or imply that You 401 | are, or that Your use of the Licensed Material is, connected 402 | with, or sponsored, endorsed, or granted official status by, 403 | the Licensor or others designated to receive attribution as 404 | provided in Section 3(a)(1)(A)(i). 405 | 406 | b. Other rights. 407 | 408 | 1. Moral rights, such as the right of integrity, are not 409 | licensed under this Public License, nor are publicity, 410 | privacy, and/or other similar personality rights; however, to 411 | the extent possible, the Licensor waives and/or agrees not to 412 | assert any such rights held by the Licensor to the limited 413 | extent necessary to allow You to exercise the Licensed 414 | Rights, but not otherwise. 415 | 416 | 2. Patent and trademark rights are not licensed under this 417 | Public License. 418 | 419 | 3. To the extent possible, the Licensor waives any right to 420 | collect royalties from You for the exercise of the Licensed 421 | Rights, whether directly or through a collecting society 422 | under any voluntary or waivable statutory or compulsory 423 | licensing scheme. In all other cases the Licensor expressly 424 | reserves any right to collect such royalties. 425 | 426 | 427 | Section 3 -- License Conditions. 428 | 429 | Your exercise of the Licensed Rights is expressly made subject to the 430 | following conditions. 431 | 432 | a. Attribution. 433 | 434 | 1. If You Share the Licensed Material (including in modified 435 | form), You must: 436 | 437 | a. retain the following if it is supplied by the Licensor 438 | with the Licensed Material: 439 | 440 | i. identification of the creator(s) of the Licensed 441 | Material and any others designated to receive 442 | attribution, in any reasonable manner requested by 443 | the Licensor (including by pseudonym if 444 | designated); 445 | 446 | ii. a copyright notice; 447 | 448 | iii. a notice that refers to this Public License; 449 | 450 | iv. a notice that refers to the disclaimer of 451 | warranties; 452 | 453 | v. a URI or hyperlink to the Licensed Material to the 454 | extent reasonably practicable; 455 | 456 | b. indicate if You modified the Licensed Material and 457 | retain an indication of any previous modifications; and 458 | 459 | c. indicate the Licensed Material is licensed under this 460 | Public License, and include the text of, or the URI or 461 | hyperlink to, this Public License. 462 | 463 | 2. You may satisfy the conditions in Section 3(a)(1) in any 464 | reasonable manner based on the medium, means, and context in 465 | which You Share the Licensed Material.

It makes use of the Navigation component within Jetpack to move the user between different screens. Each screen is implemented as a Fragment. 8 | The app navigates using buttons, the Action Bar, and the Navigation Drawer. 9 | Since students haven't yet learned about saving data or the Android lifecycle, it tries to eliminate bugs caused by configuration changes. 10 | 11 | ## Screenshots 12 | 13 | ![Screenshot1](screenshots/screen_1.png) ![Screenshot2](screenshots/screen_2.png) 14 | 15 | ## How to use this repo while taking the course 16 | 17 | 18 | Each code repository in this class has a chain of commits that looks like this: 19 | 20 | ![listofcommits](https://d17h27t6h515a5.cloudfront.net/topher/2017/March/58befe2e_listofcommits/listofcommits.png) 21 | 22 | These commits show every step you'll take to create the app. Each commit contains instructions for completing the that step. 23 | 24 | Each commit also has a **branch** associated with it of the same name as the commit message, seen below: 25 | 26 | ![branches](https://d17h27t6h515a5.cloudfront.net/topher/2017/April/590390fe_branches-ud855/branches-ud855.png 27 | ) 28 | Access all branches from this tab 29 | 30 | ![listofbranches](https://d17h27t6h515a5.cloudfront.net/topher/2017/March/58befe76_listofbranches/listofbranches.png 31 | ) 32 | 33 | 34 | ![branchesdropdown](https://d17h27t6h515a5.cloudfront.net/topher/2017/April/590391a3_branches-dropdown-ud855/branches-dropdown-ud855.png 35 | ) 36 | 37 | The branches are also accessible from the drop-down in the "Code" tab 38 | 39 | 40 | ## Working with the Course Code 41 | 42 | Here are the basic steps for working with and completing exercises in the repo. 43 | 44 | The basic steps are: 45 | 46 | 1. Clone the repo 47 | 2. Checkout the branch corresponding to the step you want to attempt 48 | 3. Find and complete the TODOs 49 | 4. Optionally commit your code changes 50 | 5. Compare your code with the solution 51 | 6. Repeat steps 2-5 until you've gone trough all the steps to complete the toy app 52 | 53 | 54 | **Step 1: Clone the repo** 55 | 56 | As you go through the course, you'll be instructed to clone the different exercise repositories, so you don't need to set these up now. You can clone a repository from github in a folder of your choice with the command: 57 | 58 | ```bash 59 | git clone https://github.com/udacity/REPOSITORY_NAME.git 60 | ``` 61 | 62 | **Step 2: Checkout the step branch** 63 | 64 | As you go through different steps in the code, you'll be told which step you're on, as well as a link to the corresponding branch. 65 | 66 | You'll want to check out the branch associated with that step. The command to check out a branch would be: 67 | 68 | ```bash 69 | git checkout BRANCH_NAME 70 | ``` 71 | 72 | **Step 3: Find and complete the TODOs** 73 | 74 | Once you've checked out the branch, you'll have the code in the exact state you need. You'll even have TODOs, which are special comments that tell you all the steps you need to complete the exercise. You can easily navigate to all the TODOs using Android Studio's TODO tool. To open the TODO tool, click the button at the bottom of the screen that says TODO. This will display a list of all comments with TODO in the project. 75 | 76 | We've numbered the TODO steps so you can do them in order: 77 | ![todos](https://d17h27t6h515a5.cloudfront.net/topher/2017/March/58bf00e7_todos/todos.png 78 | ) 79 | 80 | **Step 4: Commit your code changes** 81 | 82 | After You've completed the TODOs, you can optionally commit your changes. This will allow you to see the code you wrote whenever you return to the branch. The following git code will add and save **all** your changes. 83 | 84 | ```bash 85 | git add . 86 | git commit -m "Your commit message" 87 | ``` 88 | 89 | **Step 5: Compare with the solution** 90 | 91 | Most exercises will have a list of steps for you to check off in the classroom. Once you've checked these off, you'll see a pop up window with a link to the solution code. Note the **Diff** link: 92 | 93 | ![solutionwindow](https://d17h27t6h515a5.cloudfront.net/topher/2017/March/58bf00f9_solutionwindow/solutionwindow.png 94 | ) 95 | 96 | The **Diff** link will take you to a Github diff as seen below: 97 | ![diff](https://d17h27t6h515a5.cloudfront.net/topher/2017/March/58bf0108_diffsceenshot/diffsceenshot.png 98 | ) 99 | 100 | All of the code that was added in the solution is in green, and the removed code (which will usually be the TODO comments) is in red. 101 | 102 | You can also compare your code locally with the branch of the following step. 103 | 104 | ## Report Issues 105 | Notice any issues with a repository? Please file a github issue in the repository. 106 | 107 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | /* 2 | * Copyright 2018, The Android Open Source Project 3 | * 4 | * Licensed under the Apache License, Version 2.0 (the "License");
