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.

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.

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.

All drawing happens on the UI thread by overriding the 11 | custom view's onDraw() method. You can use this technique when drawing 12 | always takes less time than a screen refresh cycle on all target devices. 13 | 14 | Pre-requisites 15 | -------------- 16 | 17 | You need to know: 18 | - How to open, build, and run apps with Android Studio. 19 | - How to extract string resources and use string resources in the code. 20 | - How to create a custom view that handles touch or click events. 21 | - Basic understanding of the activity lifecycle. 22 | 23 | Getting Started 24 | --------------- 25 | 26 | 1.
