Each app sample is an independent project in DevEco Studio. You can import a project into DevEco Studio to learn how to use APIs in the sample by browsing code, building the project, and installing and running the app. 11 12## Content <a name="sectionMenu"></a> 13 14- Basic 15 - [`Screenshot`：Screenshot （ArkTS）（API9）](code/SystemFeature/Media/Screenshot) 16- AppSample 17 - [`Chat`：Chat Sample（ArkTS）（API9）](code/Solutions/IM/Chat) 18- Account 19 - [`AppAccountManager`：App Account Manager （ArkTS）（API9）](code/BasicFeature/Security/AppAccountManager) 20- Communication 21 - [`RPC`：RPC Connection （ArkTS）（API9）](code/BasicFeature/Connectivity/RPC) 22 - [`Wlan`：WLAN （ArkTS）（API9）](code/SystemFeature/Connectivity/Wlan) 23- ability 24 - [`JsDistributedMusicPlayer`：Distributed Music Player（JS）（API10）](code/SuperFeature/DistributedAppDev/JsDistributedMusicPlayer) 25 - [`FormExtAbility`：Stage Form（ArkTS）（API9）](code/SystemFeature/Widget/FormExtAbility) 26 - [`MissionManager`：System Mission Manager(ArkTS)（API9）](code/SystemFeature/ApplicationModels/MissionManager) 27- common 28 - [`Clock`：Clock（JS）（API10）](code/Solutions/Tools/JsClock) 29 - [`DistributeCalc`：Distributed Calculator（JS）（API10）](code/SuperFeature/DistributedAppDev/DistributeCalc) 30 - [`ResourceManager`：Resource Manager（ArkTS）（API9）](code/BasicFeature/Resource/ResourceManager) 31 - [`International`：i18n（ArkTS）（API9）](code/SystemFeature/Internationalnation/International) 32- data 33 - [`KvStore`：Distributed Database（ArkTS）（API9）](code/SuperFeature/DistributedAppDev/Kvstore) 34 - [`DistributedRdb`：Distributed RDB（ArkTS）（API9）](code/SuperFeature/DistributedAppDev/DistributedRdb) 35 - [`Preferences`：Preference（ArkTS）（API9）](code/BasicFeature/DataManagement/Preferences) 36 - [`DistributedNote`：Distributed Memo (ArkTS)（API9）](code/SuperFeature/DistributedAppDev/DistributedNote) 37- device 38 - [`Sensor`：Sensor（ArkTS）（API9）](code/BasicFeature/DeviceManagement/Sensor) 39 - [`Vibrator`：Vibrator（ArkTS）（API9）](code/BasicFeature/DeviceManagement/Vibrator) 40 - [`DeviceUsageStatistics`：Device Usage Statistics（ArkTS）（API9）](code/SystemFeature/DeviceUsageStatistics/DeviceUsageStatistics) 41 - [`Browser`：Browser（ArkTS）（API9）](code/BasicFeature/Web/Browser) 42- Graphics 43 - [`Window`：Window(ArkTS)（API9）](code/SystemFeature/WindowManagement/WindowManage) 44- media 45 - [`Recorder`：Recorder（ArkTS）（API9）](code/SystemFeature/Media/Recorder) 46 - [`MultiMedia`：Multi Media（ArkTS）（API9）](code/Solutions/Media/MultiMedia) 47- DFX 48 - [`FaultLogger`：Fault Logger（ArkTS）（API9）](code/BasicFeature/DFX/FaultLogger) 49 - [`Logger`：Logger(ArkTS)（API9）](code/BasicFeature/DFX/Logger) 50- Telephony 51 - [`Call`：Call（ArkTS）（API9）](code/SystemFeature/Telephony/Call) 52 - [`Message`：Message（ArkTS）（API9）](code/SystemFeature/Telephony/Message) 53 - [`RadioTech`：Radio Tech（ArkTS）（API9）](code/BasicFeature/Telephony/RadioTech) 54 - [`SimManager`：SIM Card Manager（ArkTS）（API9）](code/BasicFeature/Telephony/SimManager) 55 - [`MobileNetwork`：Cellular Network(ArkTS)（API9）](code/BasicFeature/Telephony/MobileNetwork) 56- thread 57 - [`JsWorker`：Launch a worker（API12）](code/LanguageBaseClassLibrary/ConcurrentModule) 58- CompleteApps 59 - [`KikaInput`：Lite Input Method（JS）（API10）](code/Solutions/InputMethod/KikaInput) 60 - [`FlipClock`：Flip Clock（ArkTS）（API9）](code/Solutions/Tools/FlipClock) 61- ETSUI 62 - [`DefiningPageLayoutAndConnection`：Defining Page Layout and Connection（ArkTS）（API9）](code/UI/ArkTsComponentCollection/DefiningPageLayoutAndConnection) 63 - [`MediaQuery`：Media Query （ArkTS）（API9）](code/UI/ArkTsComponentCollection/MediaQuery) 64 - [`AdaptiveCapabilities`：AdaptiveCapabilities（ArkTS）（API9）](code/SuperFeature/MultiDeviceAppDev/AdaptiveCapabilities) 65 - [`Game2048`：2048 Game（ArkTS）（API9）](code/Solutions/Game/Game2048) 66 - [`Lottie`：Lottie（ArkTS）（API9）](code/Solutions/Game/Lottie) 67- Notification 68 - [`CustomCommonEvent`：Custom Common Event（ArkTS）（API9）](code/BasicFeature/Notification/CustomCommonEvent) 69 - [`CustomEmitter`：Custom Emitter （ArkTS）（API9）](code/BasicFeature/Notification/CustomEmitter) 70 - [`CustomNotification`：Subscribe&Send Notification （ArkTS）（API9）](code/BasicFeature/Notification/CustomNotification) 71- Network 72 - [`Http`：http Request（ArkTS）（API9）](code/BasicFeature/Connectivity/Http) 73 - [`Socket`：Socket（ArkTS）（API9）](code/BasicFeature/Connectivity/Socket) 74- Preset 75 - [`ArkTSClock`：Clock（ArkTS）（API9）](code/Solutions/Tools/ArkTSClock) 76 - [`ArkTSDistributeCalc`：Distributed Calculator（ArkTS）（API9）](code/SuperFeature/DistributedAppDev/ArkTSDistributedCalc) 77 - [`ArkTSDistributedMusicPlayer`：Distributed Music Player (ArkTS)（API9）](code/SuperFeature/DistributedAppDev/ArkTSDistributedMusicPlayer) 78- PackageManagement 79 - [`ZipLib`：zip&unzip(ArkTS)（API9）](code/LanguageBaseClassLibrary/ZipLib) 80- ResourcesSchedule 81 - [`Flybird`：Game（ArkTS）（API9）](code/SystemFeature/TaskManagement/Flybird) 82 83## Usage<a name="section17988202503116"></a> 84 851. Import an independent app sample project into DevEco Studio for compilation, building, running, and debugging. 862. Some samples contain multiple modules. You can compile and build a single module to generate a HAP file or compile and build the entire project to generate multiple HAP files. 873. After HAP installation and execution, you can view the execution effect of the sample on the device and then conduct debugging. 88 89## Limitations<a name="section18841871178"></a> 90 911. Before installing and running the sample, check the **deviceType** field in the **config.json** file to obtain the device types supported by the sample. You can modify this field to enable the sample to run on your target device. \(The **config.json** file is generally stored in the **entry/src/main** directory, which may be different depending on the samples.\) 922. If you want to run the app sample on OpenHarmony, configure the development environment by referring to [DevEco Studio \(OpenHarmony\) User Guide](https://gitee.com/openharmony/docs/blob/master/en/application-dev/quick-start/Readme-EN.md). 933. App samples that can run on standard-system or small-system devices (as stipulated in **Readme**) must run on OpenHarmony. 94
