鸿蒙系统（HarmonyOS）获取APP与ability信息

一、设计布局

<Button
    ohos:height="match_content"
    ohos:width="match_parent"
    ohos:id="$+id:GetAppInfo"
    ohos:padding="5fp"
    ohos:top_margin="10fp"
    ohos:left_margin="20fp"
    ohos:right_margin="20fp"
    ohos:bottom_margin="10fp"
    ohos:text_size="22fp"
    ohos:text_color="#fff"
    ohos:background_element="$graphic:background_button"
    ohos:text="获取应用程序信息"></Button>

<Text
    ohos:height="match_content"
    ohos:width="match_parent"
    ohos:id="$+id:ShowAPPInfo"
    ohos:left_padding="20fp"
    ohos:right_padding="20fp"
    ohos:top_padding="0fp"
    ohos:text_size="14fp"
    ohos:text_color="#fff"
    ohos:multiple_lines="true"
    ohos:text=""></Text>

二、打开MainAbilitySlice.JAVA文件录入以下关键代码

private static final HiLogLabel hiLogLabel = new HiLogLabel(HiLog.LOG_APP, 0x00888, "BingJu.NETWorkLog");

private Text ShowAPPInfo;
@Override
public void onStart(Intent intent) {
    super.onStart(intent);
    super.setUIContent(ResourceTable.Layout_ability_main);
    Button GetAPPInfo=(Button) findComponentById(ResourceTable.Id_GetAPPInfo);
    GetAPPInfo.setClickedListener(clickedListener);
    ShowAPPInfo=(Text) findComponentById(ResourceTable.Id_ShowAPPInfo);
}

public Component.ClickedListener clickedListener= component -> {
    switch (component.getId()){
        case ResourceTable.Id_GetAPPInfo:
            ShowAPPInfo.setText("");
            this.UpdateAPPInfo();

            break;
        default:
            break;
    }
};

public void UpdateAPPInfo(){
    TaskDispatcher taskDispatcher=this.getUITaskDispatcher();
    taskDispatcher.asyncDispatch(() -> {
        AbilityInfo abilityInfo = this.getAbilityInfo();;
        try{
            //ShowAPPInfo.append("包名："+abilityInfo.bundleName+"rn");
            //ShowAPPInfo.append("类名："+abilityInfo.className+"rn");

            }
