--------------------------------------------------------------------------------
1 | # Contributor Covenant Code of Conduct
2 |
3 | ## Our Pledge
4 |
5 | In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
6 |
7 | ## Our Standards
8 |
9 | Examples of behavior that contributes to creating a positive environment include:
10 |
11 | * Using welcoming and inclusive language
12 | * Being respectful of differing viewpoints and experiences
13 | * Gracefully accepting constructive criticism
14 | * Focusing on what is best for the community
15 | * Showing empathy towards other community members
16 |
17 | Examples of unacceptable behavior by participants include:
18 |
19 | * The use of sexualized language or imagery and unwelcome sexual attention or advances
20 | * Trolling, insulting/derogatory comments, and personal or political attacks
21 | * Public or private harassment
22 | * Publishing others' private information, such as a physical or electronic address, without explicit permission
23 | * Other conduct which could reasonably be considered inappropriate in a professional setting
24 |
25 | ## Our Responsibilities
26 |
27 | Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
28 |
29 | Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
30 |
31 | ## Scope
32 |
33 | This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
34 |
35 | ## Enforcement
36 |
37 | Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at nachiketavadera@outlook.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
38 |
39 | Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
40 |
41 | ## Attribution
42 |
43 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

10 | ## Summary
11 |
12 | The base of this project is LED provided along with the Camera in a typical Android smart phone. After seeing that Play Store has a number of apps that ask for unnecessary permissions, I decided to create an app that toggles the LED without asking for any type of permission. This app also implements a service that detects when the device is shook (used to toggle the flashlight).

32 | ## Code
33 |
34 | The majority of the code is written in Java and is simple. For detecting shake motion:
35 | Declare global variables:
36 |
37 | ```java
38 | SensorManager sensorManager = null;
39 | public static final float SHAKE_THRESHOLD = 10.25f; // How hard should user shake to invoke the service
40 | public static final int MIN_TIME_BETWEEN_SHAKES = 1000;
41 | private long lastShakeTime = 0;
42 | private boolean isFlashlightOn = false;
43 | ```
44 |
45 | Initialize sensorManager:
46 |
47 | ```java
48 | sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
49 | if (sensorManager != null) {
50 | Sensor accelerometer = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
51 | sensorManager.registerListener((SensorEventListener) this, accelerometer, SensorManager.SENSOR_DELAY_NORMAL);
52 | }
53 | ```
54 |
55 | Make class implement SensorEventListener interface and override it's onSensorChanged method:
56 |
57 | ```java

114 | ## Contributing
115 |
116 | Any help, including feedback, is highly appriciated. I have just started out with Android and I’m relatively new to app development.
117 |
118 | 1. Fork it!
119 | 2. Create your feature branch: `git checkout -b new-branch`
120 | 3. Commit your changes: `git commit -am 'Make a valuable addition'`
121 | 4. Push to the branch: `git push origin new-feature`
122 | 5. Submit a pull request :D
123 |
124 | ## Next Step
125 |
126 | Once staretd, an app can never be completely finished.
127 |
128 | 1. Provide users option to toggle the service ON/OFF.
129 | 2. Optimize code.
130 | 3. Make flashlight toggle easier.

156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.
