[](https://android-arsenal.com/details/1/7018) [](https://github.com/duanhong169/Camera/blob/master/LICENSE) [](https://appcenter.ms)
2 |
3 | Use Android camera to take pictures and videos, based on [camera2](https://developer.android.com/reference/android/hardware/camera2/package-summary) api.
4 |
5 | 
6 |
7 | ## Features
8 |
9 | * Auto filled `CameraView` for previewing
10 | * Support both image capture & video record
11 | * Configurable audio/video size and aspect ratio, auto focus, tap to focus, flash control, pinch to zoom, etc.
12 |
13 | ## Gradle
14 |
15 | ```
16 | dependencies {
17 | implementation 'com.github.duanhong169:camera:${latestVersion}'
18 | ...
19 | }
20 | ```
21 |
22 | > Replace `${latestVersion}` with the latest version code. See [releases](https://github.com/duanhong169/Camera/releases).
23 |
24 | ## Usage
25 |
26 | * Add `CameraView` into your layout xml:
27 |
28 | ```xml
29 |
42 | ```
43 |
44 | > See [`top_defaults_camera_attrs.xml`](./camera/src/main/res/values/top_defaults_camera_attrs.xml) for all supported attributes.
45 |
46 | * Create a `Photographer` with the `CameraView`:
47 |
48 | ```java
49 | @Override
50 | protected void onCreate(@Nullable Bundle savedInstanceState) {
51 | super.onCreate(savedInstanceState);
52 |
53 | // ...
54 |
55 | CameraView preview = findViewById(R.id.preview);
56 | photographer = PhotographerFactory.createPhotographerWithCamera2(this, preview);
57 |
58 | // ...
59 | }
60 | ```
61 |
62 | * Implement and set `Photographer.OnEventListener` to receive events from the camera:
63 |
64 | ```java
65 | photographer.setOnEventListener(new SimpleOnEventListener() {
66 | @Override
67 | public void onDeviceConfigured() {}
68 |
69 | @Override
70 | public void onPreviewStarted() {}
71 |
72 | @Override
73 | public void onZoomChanged(float zoom) {}
74 |
75 | @Override
76 | public void onPreviewStopped() {}
77 |
78 | @Override
79 | public void onStartRecording() {}
80 |
81 | @Override
82 | public void onFinishRecording(String filePath) {}
83 |
84 | @Override
85 | public void onShotFinished(String filePath) {}
86 |
87 | @Override
88 | public void onError(Error error) {}
89 | });
90 | ```
91 |
92 | * Start/stop preview in `onResume()`/`onPause()`:
93 |
94 | ```java
95 | @Override
96 | protected void onResume() {
97 | super.onResume();
98 | photographer.startPreview();
99 | }
100 |
101 | @Override
102 | protected void onPause() {
103 | photographer.stopPreview();
104 | super.onPause();
105 | }
106 | ```
107 |
108 | * `PhotographerHelper` is your friend:
109 |
110 | ```java
111 | photographerHelper = new PhotographerHelper(photographer); // init with photographer
112 | photographerHelper.setFileDir(Commons.MEDIA_DIR); // set directory for image/video saving
113 | photographerHelper.flip(); // flip back/front camera
114 | photographerHelper.switchMode(); // switch between image capture/video record
115 | ```
116 |
117 | See a complete usage in the app sample code.

82 | institute patent litigation against any entity (including a
83 | cross-claim or counterclaim in a lawsuit) alleging that the Work
84 | or a Contribution incorporated within the Work constitutes direct
85 | or contributory patent infringement, then any patent licenses
86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.
88 |
89 | 4. Redistribution. You may reproduce and distribute copies of the
90 | Work or Derivative Works thereof in any medium, with or without
91 | modifications, and in Source or Object form, provided that You

104 | the Derivative Works; and
105 |
106 | (d) If the Work includes a "NOTICE" text file as part of its
107 | distribution, then any Derivative Works that You distribute must
108 | include a readable copy of the attribution notices contained

110 | pertain to any part of the Derivative Works, in at least one
111 | of the following places: within a NOTICE text file distributed
112 | as part of the Derivative Works; within the Source form or
113 | documentation, if provided along with the Derivative Works; or,
114 | within a display generated by the Derivative Works, if and
115 | wherever such third-party notices normally appear. The contents
116 | of the NOTICE file are for informational purposes only and
117 | do not modify the License. You may add Your own attribution
118 | notices within Derivative Works that You distribute, alongside
119 | or as an addendum to the NOTICE text from the Work, provided
120 | that such additional attribution notices cannot be construed
121 | as modifying the License.
122 |
123 | You may add Your own copyright statement to Your modifications and
124 | may provide additional or different license terms and conditions
125 | for use, reproduction, or distribution of Your modifications, or

127 | reproduction, and distribution of the Work otherwise complies with
128 | the conditions stated in this License.
129 |
130 | 5. Submission of Contributions. Unless You explicitly state otherwise,
131 | any Contribution intentionally submitted for inclusion in the Work
132 | by You to the Licensor shall be under the terms and conditions of
133 | this License, without any additional terms or conditions.
134 | Notwithstanding the above, nothing herein shall supersede or modify
135 | the terms of any separate license agreement you may have executed
136 | with Licensor regarding such Contributions.
137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,
140 | except as required for reasonable and customary use in describing the
141 | origin of the Work and reproducing the content of the NOTICE file.
142 |
143 | 7. Disclaimer of Warranty. Unless required by applicable law or
144 | agreed to in writing, Licensor provides the Work (and each
145 | Contributor provides its Contributions) on an "AS IS" BASIS,
146 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 | implied, including, without limitation, any warranties or conditions
148 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 | PARTICULAR PURPOSE. You are solely responsible for determining the
150 | appropriateness of using or redistributing the Work and assume any
151 | risks associated with Your exercise of permissions under this License.

154 | whether in tort (including negligence), contract, or otherwise,
155 | unless required by applicable law (such as deliberate and grossly
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.
