How do I determine whether an application is a system application?

Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)

Solution

Use bundleManager.getApplicationInfo (available only for system applications) to obtain application information, and check the value of systemApp in the information. The application is a system application if the value is true.

How do I obtain the version code and version name of an application?

Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)

Solution

Use bundleManager.getBundleInfoForSelf() to obtain the bundle information, which contains the version code (specified by BundleInfo.versionCode) and version name (specified by BundleInfo.versionName) .

Example

import bundleManager from '@ohos.bundle.bundleManager';
import hilog from '@ohos.hilog';
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT;
try {
  bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {
    const versionCode = data.versionCode;
    const versionName = data.versionName;
    hilog.info(0x0000, 'testTag', `successfully. versionCode: ${versionCode}, versionName: ${versionName}`);    
  }).catch(err => {
    hilog.error(0x0000, 'testTag', 'failed. Cause: %{public}s', err.message);
  });
} catch (err) {
  hilog.error(0x0000, 'testTag', 'failed: %{public}s', err.message);
}

How do I obtain the application version number, version name, and screen resolution?

Applicable to: OpenHarmony 3.2 Beta5

Solution

Obtain the bundle information from the @ohos.bundle.bundleManager module.

The bundle information contains the application version number and version name.

import bundleManager from '@ohos.bundle.bundleManager';
...
bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION).then((bundleInfo)=>{
  let versionName = bundleInfo.versionName; // Application version name.
  let versionNo = bundleInfo.versionCode; // Application version number.
}).catch((error)=>{
  console.error("get bundleInfo failed,error is "+error)
})

Obtain screenDensity from the @ohos.app.ability.Configuration module. screenDensity contains the screen resolution information.

import common from '@ohos.app.ability.common';
...
let context = getContext(this) as common.UIAbilityContext;
let screenDensity = context.config.screenDensity;

How do I obtain the source file path of the current application?

Applicable to: OpenHarmony 3.2 Beta 5 (API version 9)

this.uiAbilityContext.abilityInfo.applicationInfo.codePath
```
Method 2: Use @ohos.bundle.bundleManager to obtain the source file path.
1. Import the @ohos.bundle.bundleManager module and use bundleManager.getBundleInfoForSelf() to obtain the bundle information.

```
import bundleManager from '@ohos.bundle.bundleManager';
bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION).then((bundleInfo)=>{
  this.sourcePath = bundleInfo.appInfo.codePath;
})
